Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polycarbonate / AS / acrylic resin alloy material and a preparation method thereof. Background technique [0002] Polycarbonate resin (i.e. PC resin) has excellent impact strength and excellent comprehensive mechanical, thermal and electrical properties. It is widely used in automobiles, aerospace, electronic appliances, engineering construction and other fields, and has become the five most widely used engineering plastics. one. Although polycarbonate has many advantages, it also has obvious disadvantages, such as high cost of polycarbonate raw materials, thickness dependence of notched impact strength, chemical resistance, insufficient scratch resistance, poor processing fluidity, easy stress cracking, etc. , which limits the application fields of polycarbonate to some extent. [0003] In order to overcome these shortcomings of polycarbonate resin and make...
