However, it has the disadvantages of poor heat resistance, low hardness, poor water resistance, low-temperature brittleness, high-temperature stickiness and the like. In recent years, silicone-modified acrylate emulsions have received much attention. Some organic silicon monomers are introduced to modify the acrylate emulsion, and the performance of the acrylate emulsion is improved by adopting related technologies, so that a high-performance copolymer emulsion is obtained, and the high-performance copolymer emulsion has better emulsion hardness, stain resistance and water resistance. The coating is used as a coating layer to be coated on the surface of a glass fiber fabric, so that the surface wear resistance of the fabric can be improved, and the fabric has better transparency.
