Problems solved by technology

With the development of the automobile industry, the requirements for auto parts are getting higher and higher, and the polycarbonate of the existing technology has been increasingly unable to meet the requirements of the automobile industry for the strength of parts
[0004] Therefore, many fiber-reinforced modified resins have appeared at home and abroad, such as increasing the strength of polycarbonate through glass fibers or carbon fibers. However, although carbon fibers have high strength and good thermal stability, they are relatively heavy, easy to rust, and easy to damage. Although glass fiber has high strength and cheap price, it is easy to melt at high temperature, which will lead to the decline of material performance

Description

technical field [0001] The invention relates to the field of plastic raw materials, in particular to a basalt fiber reinforced PC composite material and a preparation method thereof. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Due to its excellent physical and chemical properties, PC engineering plastics are widely used in various industries. Its three major application areas are glass assembly industry, automobile industry, electronics and electrical appliances industry, followed by industrial machinery parts, CDs, packaging, computers and other offices. Equipment, medical and healthcare, film, leisure and protective equipment, etc. [0003] In the automotive industry, polycarbonate has good impact resistance, thermal distortion resistance, good weat...
