Application of water-based polyurethane paint (WPU) Polyurethane (PU) is the abbreviation of polyurethane. This type of paint was developed in the 1960s and was widely used in the surface finishing of wood, metal and other materials in the late 1970s. Water-based polyurethane (WPU) is a type of polyurethane and is mainly used for the surface finishing of wood products. It is characterized by using water instead of organic solvents as the dispersion medium of the raw material system, so it is more environmentally friendly than traditional wood floor paints. At the same time, WPU paint also has the advantages of good surface hardness, strong wear resistance, aging resistance and strong adhesion, etc., and is widely used in the surface finishing of wood products such as solid wood floors and solid wood furniture.”1. As early as the 1990s, Surface finishing has become an important application field of waterborne polyurethane coatings, and the research on waterborne polyurethane coatings in the industry has become increasingly mature and perfect.
Application of UV paint UV-curable paint is also called photosensitive paint. In the 1960s, developed countries such as Europe and the United States began to develop and use UV paint as a surface finishing material for wood products. It was not until the 1990s that UV paint gradually entered the Chinese people's field of vision. Although the development of uV paint in my country started late, it can develop rapidly and occupy the market due to its good surface performance and outstanding environmental protection characteristics.
UV paint can automatically spray liquid paint onto the surface of wood products such as floors using professional finishing equipment. The photosensitive organic matter in the paint is decomposed under the irradiation of ultraviolet light (wavelength 320-390 nm) to generate free radicals, and the resin is rapidly cured at the same time. conjunctiva. Due to the uniformity of the molecular structure and the strong three-dimensionality of the uV paint film, its surface hardness is high, so its surface hardness and thickness can meet the needs of indoor sports floors; in addition, the uV paint also has good transparency. The application of uV paint on indoor wooden sports floors is becoming more and more extensive. The organic volatiles in UV paint can be decomposed and volatilized in the process of ultraviolet light irradiation, so it is one of the most environmentally friendly finishing materials in the current wood product surface finishing materials.
