Painting furniture is a process that determines whether your efforts to paint, repair, polish, color, and polish your furniture are ultimately lost. Some people may think that painting is just a common process, and some people think it is a creative link. In any case, as long as you use the right materials, take some time, and maintain a little patience, lacquering is still very easy. Wood House and you discuss how to choose the topcoat that best suits your furniture wood. In addition, the Wood House will explore some finishing techniques (including preparation and drying techniques). In this way, no matter what kind of topcoat you choose, the furniture will last forever.
Wood lacquer can generally be divided into two types of water-based lacquer and oil-based lacquer (referred to as paint). Of course, there are other classifications, for example, according to the level of use can be divided into primer and topcoat; according to the gloss can be divided into high-light, semi-matte Matte; according to its use can be divided into furniture paint, floor paint; according to the nature can be divided into single-component, two-component and three-component.
(1) Water-based paint
The first type is water-based wood lacquer with acrylic acid as the main component. It is mainly composed of acrylic emulsion and suitable for waterborne wood primer and matte finish. The main feature of this product is that it has good adhesion and does not deepen the color of wood. However, it is inferior in abrasion resistance and chemical resistance. Because of the poor gloss, it is impossible to produce high-gloss paint, and the hardness is generally poor, and the film-forming performance is poor. Because of its low cost and low technical content, it has become an entry-level product on the market.
The second type is water-based wood lacquer based on the combination of acrylic acid and polyurethane.
In addition to adhering to the characteristics of acrylic paint, it also features wear resistance and chemical resistance (the first two types are mostly used for doors and windows, furniture). It has the advantages of the above two types, the cost is relatively moderate, it can be self-crosslinking or can be used in two-component system, with good hardness, fast drying, good wear resistance, good chemical resistance, low yellowing or no yellowing, suitable for Make bright matt paint, primer, outdoor paint, etc.
The third category is 100% polyurethane waterborne wood lacquer
The abrasion resistance of polyurethane water-based wood lacquer is even several times that of oil-based paint, which is a high-grade product in water-based paint. Including aromatic and aliphatic polyurethane dispersions, waterborne wood lacquers based on aliphatic polyurethane dispersions, excellent yellowing resistance and outdoor. Their film-forming properties are good, self-crosslinking gloss is high, wear resistance is good, and bubbles and shrinkage cavities are not easily generated. But the hardness is general, the price is more expensive, suitable for making bright topcoat, floor paint, etc.;
The fourth category is water-based wood lacquer based on water-based two-component polyurethane.
The product is a two-component product, one of which is an aqueous polyurethane dispersion with -OH, the two components are aqueous curing agents, mainly aliphatic; the two components are cross-linked by mixing construction. It can significantly improve the water resistance, hardness, film fullness and gloss of water-based wood lacquer, and has better comprehensive performance and high anti-yellowing performance, especially suitable for outdoor coating. However, the product is complicated in construction and requires professional guidance.
1. Advantages and disadvantages of water-based paint
A, water-soluble paint, non-toxic and environmentally friendly, does not contain harmful solvents such as benzene, does not contain free TDI.
B. The construction is simple and convenient, and it is not easy to have common problems with oil paints such as bubbles and particles, and the paint film feels good.
C, high solid content, full film.
D, no yellowing, excellent water resistance, no burning.
F, can be constructed at the same time as other paints such as latex paint
G, part of the water-based paint is not high hardness, easy to scratch, this should be paid special attention when choosing.
In general, water-based paints are a good choice in terms of construction and environmental protection, except for a slightly higher price.
(two) paint
1, paint classification, the current market has more than a thousand kinds of paint on the market, the variety of colors, the name is also inconsistent, but according to the composition of the properties, the commonly used paints are divided into the following:
A, large paint, also known as natural paint, there are raw paint, cooked paint. The raw paint is toxic, the paint film is rough, and it is rarely used directly. It is processed into mature paint or modified to make various refined paints. The paint is suitable for drying in a humid environment. The resulting paint film has good gloss, toughness, high stability, strong acid resistance, but slow drying. The modified quick-drying varnish and Tiezhuang lacquer have low toxicity, tough film, can be sprayed and brushed, convenient to construct, acid and water resistant, and suitable for advanced coating.
B, clear oil, also known as cooked oil, paint oil. It can be used as a raw material for the preparation of original paint and anti-rust paint. It can also be used alone. Some clear oils (thinned thick paint and red dan) can be applied to wood or metal rust and corrosion protection. Add appropriate amount of pigment to form a colored oil.
C, thick paint, also known as lead oil. It is a mixture of pigment and earth oil. It needs to be diluted with oil and solvent to be used. It is widely used as a primer for the top layer, or it can be used as a surface layer alone. Suitable for low-demand buildings and wood primers, filling materials for water pipe joints.
D, blending paint, also known as blending paint. It is the most commonly used type of paint. The texture is soft, uniform, moderately thick, corrosion-resistant, light-resistant, long-lasting, non-cleaving, strong hiding power, good durability and convenient construction. It is divided into oil-soluble blending paint and magnetic blending paint. The latter is now known as Dudan blending paint. Suitable for magnetic blending paint indoors, this blending paint is better than oily blending paint, the paint film is hard, bright and smooth, but the weather resistance is worse than oily blending paint.
E, varnish
The varnish is divided into two categories: oil-based varnish and resin varnish. The former is commonly known as “Fan Lishuiâ€, and the latter is commonly known as “bubble waterâ€. It is a clear paint without pigment. The resins used in the resin varnish are mainly polyester resin, polyurethane, acrylic resin and the like. There are several types of varnish:
â— Ester glue varnish, also known as water resistant varnish. The paint film is bright and has good water resistance, but the gloss is not durable and the drying property is poor. Suitable for wooden furniture, doors and windows, slab coating and metal surface glazing.
â— Novolac, commonly known as Yongming paint. Fast drying, the film is tough and durable, good gloss, heat resistance, water resistance, weak acid and alkali resistance. The disadvantage is that the paint film is easy to yellow and brittle. Suitable for wooden furniture doors and windows, slab coating and metal surface glazing.
â— Alkyd varnish, also known as Sambo paint. This paint has better adhesion, gloss and durability than the first two. It is fast drying, high hardness, polished, polished and bright. However, the film is brittle, heat resistant, and poor in atmospheric resistance. Suitable for painting interior doors and windows, floors, furniture, etc.
â— Nitro varnish, also known as clear spray paint, wax. It has the characteristics of fast drying, hard, bright, wear-resistant and durable. It is an advanced coating suitable for the coating of wood and metal surfaces. It is used for high-grade doors and windows, siding and handrails.
â— Shellac varnish, also known as blister water, alcohol varnish, also referred to as lacquer. It is a solution prepared by dissolving insect film in alcohol above 95 degrees. The paint is easy to use, fast drying, and the paint film is hard and bright. The disadvantages are poor water resistance and weather resistance, loss of sunlight during sun exposure, and whitening of hot water. Generally used for the finishing of indoor wood furniture.
â— Acrylic varnish. It can be dried at room temperature, has good weather resistance, light resistance, heat resistance, mildew resistance and adhesion, but has poor gasoline resistance. Suitable for spraying anodized aluminum alloy surfaces. Used as a sealer in wood finishing, the paint film is hard and bright, can be insulated, and it is dry quickly. It is easy to whiten when hot water is used, and its adhesion is good. It is mainly suitable for wood and furniture. Objects susceptible to moisture and heat are not suitable.
F, enamel, is made of varnish as the base material, added by pigment grinding. After the coating is dried, it is magneto-optic and the coating film is hard. Commonly used are phenolic enamel and alkyd enamel, suitable for metal screen mesh, etc. . The anti-rust paint has zinc yellow and iron red epoxy primer. The paint film is tough and durable, and has good adhesion. If used together with ethylene phosphating primer, it can improve heat resistance and salt spray resistance. It is suitable for coastal areas and temperature. The base of tropical metal materials.
Home decoration, the most used is polyurethane wood lacquer, and door and window alcohol enamel enamel, alkyd blending paint. Polyurethane wood lacquer contains toluene diisocyanate, which is a harmful substance that has tearing effect and also causes mild skin coloration. Its vapor will have strong irritation to the respiratory tract, even at low concentrations of vapor. There are also 2-5% of people who develop allergic reactions similar to allergic asthma. Organic solvents such as turpentine, turpentine, gasoline, acetone, and ether used in alcoholic and alkyd paints are unpleasant and even unpleasant. Some counterfeit and shoddy products use polyester waste silk instead of alkyd resin, and the use of super solvents and pure benzene, the consequences are even more serious. Pay special attention to the selection of quality products when using. After the room has been painted, it should be ventilated at the right time. After the renovation of the new home, it is best to vacate for 1-2 months.
G, super environmentally friendly plant paint
The natural plant-based paints that have been introduced vary from raw material selection to processing. Its raw materials are selected from linseed oil, orange oil, sycamore oil, hemp resin, turpentine, eucalyptus oil and other natural plants. It is a new paint coating synthesized by high-tech which conforms to the natural ecological balance. Just like the tung oil used in the lacquer ware used in ancient times, natural plant-type paint can be applied to the top surface of the living room wall and the furniture surface, and it will not cause any harm to the human body during the painting operation and volatilization after painting. Since the pigments and dilution solvents of natural botanical paints are also extracted from natural plants, they are also free of volatile harmful gases. Workers can work in a closed space environment and can enter after painting. Even if the remaining material evaporates, it can return to nature to circulate. In addition, the various ingredients from the plant have an affinity with the natural ecological environment, so that during the painting operation, the constructor can smell the smell of orange or pine leaves, making people feel fresh and not stimulated like chemical paint. People are crying, throat discomfort, and even other patients.
