Abstract

The invention discloses a polycarbonate modified plastic which is prepared from the following raw materials in parts by mass: 80-100 parts of polycarbonate, 5-10 parts of nano calcium carbonate, 5-10 parts of polyurethane, 3-5 parts of glass fiber, 5-10 parts of carbon fiber, 2-5 parts of coupling agent, 1-3 parts of flame retardant, 1-3 parts of dispersing agent and 1-3 parts of antioxidant. The nano calcium carbonate is filled into the polycarbonate modified plastic to enhance the toughness of the polycarbonate. The added carbon fiber and glass fiber further enhance the yield strength and elastic modulus of the polycarbonate, lower the elongation at yield of the polycarbonate and greatly enhance the mechanical properties of the polycarbonate. Meanwhile, the added flame retardant enhances the flame retardancy of the polycarbonate.

Description

technical field [0001] The invention relates to the field of plastic modification, in particular to a polycarbonate modified plastic. Background technique [0002] Polycarbonate is a thermoplastic engineering resin with special molecular structure and excellent comprehensive performance. At present, its application is developing rapidly. It ranks second in the application of five major engineering resins, second only to the application of nylon. The molecular chain of polycarbonate contains benzene ring and carbonate structure, so the rigidity of its molecular chain is very large. Due to the special molecular structure of polycarbonate, many unique mechanical, thermal, optical and other properties of polycarbonate are determined. First of all, the mechanical properties of polycarbonate, it has excellent impact resistance, heat resistance, cold resistance and good wear resistance. Tensile properties and modulus of elasticity are also better. But polycarbonate also has many...
