Problems solved by technology

However, the outdoors will be exposed to the sun and rain, and as the rain soaks, there will be problems of falling between the paint films and poor adhesion
The existing UV permeable bottoms used for calcium-silicon boards have problems such as poor yellowing resistance and poor outdoor weather resistance, which cannot meet the requirements of the market and customers
This severely restricts the development and promotion of UV paint, and affects the economic benefits of the UV industry.

Abstract

The invention provides a UV infiltration bottom for a calcium silicon plate, wherein the UV infiltration bottom comprises: an aromatic polyurethane acrylic resin, aliphatic polyurethane acrylate, propoxylated neopentyl glycol diacrylate, trimethylolpropane triacrylate, an organosilicon antifoaming agent and a photoinitiator. According to the present invention, by compounding aromatic polyurethaneacrylic resin, aliphatic polyurethane acrylate, propoxylated neopentyl glycol diacrylate and trimethylolpropane triacrylate, the obtained UV infiltration bottom has good water resistance, can providegood interlayer adhesion to substrates and paint films, further has advantages of excellent leveling property, excellent yellowing resistance and excellent outdoor weather resistance, and can well meet the applications of the UV infiltration bottom in outdoor wall surfaces, especially in calcium silicon plates.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a UV permeable bottom for calcium-silicon boards. Background technique [0002] UV paint is a light-curing paint. It is currently a widely used furniture paint. Its main features are: after strong ultraviolet light curing treatment, the color is stable and always new. The UV paint film has a three-dimensional structure with high hardness, good wear resistance, and good transparency. The product is scratch-resistant and friction-resistant, and can stand the test of time. UV paint is widely used in office furniture, etc. In recent years, it has become more and more widely used in indoor and outdoor decorative panels. [0003] As a decorative board, calcium silicate board is also widely used in UV paint on outdoor walls. However, it will be exposed to the sun and rain outdoors, and as the rain soaks, there will be problems of falling between the paint films and poor adhe...
