Waterborne coatings are water-based coatings. Water-based paints include water-soluble paints, water-reducible paints, and water-dispersible paints (latex paints). The production process of waterborne wood lacquer is a simple physical mixing process. Waterborne wood lacquer is water-based solvent without any harmful volatilization. It is the safest and most environmentally friendly furniture lacquer coating. However, due to the combination of coating effect and coating process, the market share of water-based furniture lacquer in the domestic market is still very low, but its low-carbon environmental protection concept is the future development direction of furniture lacquer. It is believed that with the continuous advancement of technology, the application of water-based furniture lacquer will become more and more extensive. The difference between waterborne wood lacquer and oily wood lacquer Oily paints have higher relative hardness and better fullness, but water-based paints are more environmentally friendly. Usually oily paints use organic solvents, often called "Tana water" or "banana water", which are contaminated and can be burned. It can be seen that water-based paints and oil-based paints are fundamentally different in terms of environmental protection and health. Waterborne wood lacquer is the most technically challenging and technologically advanced product in wood coatings. Water-based wood lacquer is more and more market-oriented because of its non-toxic, environmentally friendly, odorless, volatile, non-flammable, non-explosive, high-safety, non-yellowing, and large brushing area. Welcome. Type of waterborne wood lacquer Although there are many brands of waterborne wood lacquers on the market today, the main components of the market can be divided into the following four categories: 1. Water-based wood lacquer with acrylic acid as the main component, the main feature is good adhesion, will not deepen the color of wood, but the wear resistance and chemical resistance are poor, the hardness of the paint film is soft, the pencil rule is HB, fullness Poor, comprehensive performance is general, construction is prone to defects. Because of its low cost and low technical content, it is the main product that most water-based paint companies are bringing to the market. This is why most people think that water-based paint is not good. The advantage is that it is cheap. 2. Water-based wood lacquer with acryl base and polyurethane composite as the main component. Its characteristics are not only adhering to the characteristics of acrylic lacquer, but also adding strong wear resistance and chemical resistance. Some enterprises are marked as water-based polyester paint. . The hardness of the paint film is good, the pencil rule is 1H, the fullness is good, and the comprehensive performance is close to the oil paint. At present, only a few companies in China can produce. 3. Polyurethane water-based paint, its comprehensive performance is superior, the fullness is high, the hardness of the paint film can reach 1.5-2H, the wear resistance even exceeds the oil paint, the service life and color matching have obvious advantages, and it is the advanced product in water-based paint. . 4. Pseudo-aqueous paint, add curing agent or chemicals, such as “hardenerâ€, “paint film enhancerâ€, “special dilution waterâ€, etc., some of which can also be diluted with water, but the solvent content is very high. It is more harmful to humans, some even exceed the toxicity of oil paints, and some companies are labeled as water-based polyester paints. Consumers can easily distinguish it. Common problems and solutions Paint film wrinkling Some construction workers use a one-time thick coating method when using a water-based wood lacquer for flat coating. The fullness is excellent, but the surface of the paint film is wrinkled. The problem is caused by the thick water-based paint film at high temperature, the surface of the paint film is quickly dried to form a film, and the thick inner layer is dry slowly, and the flow of the paint during the drying process produces a poor tension, resulting in uneven film surface. That is wrinkling. Therefore, do not apply thick coating once during construction. In particular, do not use direct pouring. Thin coating should be adopted to ensure uniform drying of the coating to achieve film smoothing effect. The adhesion of the paint film is poor in summer and the humidity in the air is high in some areas. After the construction of the general water-based wood lacquer, it will be found that the adhesion between the coating layers is not strong, resulting in poor adhesion, and the layers are peeled off from each other, and even the whole piece can be peeled off like a peeling. The direct cause of poor adhesion between the layers of the paint film is that the painter does not polish the layers during construction. Because the painter is in a hurry, in the next process, it is not polished, but is directly applied to the previous paint film. In addition, the temperature is high, and the time required for the wet paint film and the dry paint film to form a firm layer is insufficient. Adhesion is affected. Therefore, the construction workers are required to fully grind each floor during high-temperature weather construction to improve adhesion, and the construction arrangement is appropriate in the morning and evening to ensure that the inherent quality of the product is reflected. Paint film cracking This phenomenon is also more common in summer construction. Because during the construction process, the coating film of the paint layer is too thick, the surface layer is dried and the film formation speed is fast, while the thick inner layer is dry slowly, which directly causes cracking of the primer. At the same time, we must also pay attention to the quality of the sheet, it is recommended to buy a stable sheet. White lacquer Mainly due to the humidity in the construction environment is too large, the coating film is too thick during construction and other reasons. Because of the high temperature in summer, the air humidity in some areas is relatively high. The drying time of the paint layer is accelerated with the increase of the temperature, but the drying time is slower; the painter may neglect the dry time during the construction process, and immediately after the paint layer is dry, another paint is applied. Causes the bottom paint layer to be completely dry. In rainy weather or in high humidity, it is easy to produce whitening of the paint layer.
