Problems solved by technology

[0002] As one of the widely used materials in construction, furniture and other fields, plastic sheet is not only low in cost but also convenient in production and molding, which makes it favored by merchants and consumers. With the increasing diversity of consumer demand, the performance of the sheet The requirements are becoming more and more stringent and targeted. Therefore, some plastic sheets currently on the market increase their toughness by adding toughening agents, and increase their weather resistance by adding light shielding agents. However, in terms of wear resistance It has always been a shortcoming of plastic boards. Since plastics are mostly resin components, the hardness of the surface is low. When it comes into contact with metal or stone and other materials, it is easy to have obvious scratch marks.
