Description

technical field [0001] The invention relates to the technical field of modified materials, in particular to an anti-aging PC-ABS alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a tough thermoplastic resin, but it is not resistant to ultraviolet light and is easily exposed to external ultraviolet light, which increases the internal heat energy of the resin and reduces the strength of the resin from both light and heat. the durability of the resin. Acrylonitrile-butadiene styrene copolymer (ABS) is a thermoplastic polymer material with high strength, good toughness and easy processing. It has excellent heat resistance and can improve the heat resistance of polycarbonate. performance, but the photoaging problem caused by its anti-ultraviolet radiation has not been solved. Therefore, in the anti-aging phenomenon of PC / ABS composite materials, it is basically to add ultraviolet absorbers and light stabilizers to the composite ...

[0002] Polycarbonate (PC) is a tough thermoplastic resin, but it is not resistant to ultraviolet light and is easily exposed to external ultraviolet light, which increases the internal heat energy of the resin and reduces the strength of the resin from both light and heat. increased resin durability

Acrylonitrile-butadiene styrene copolymer (ABS) is a thermoplastic polymer material with high strength, good toughness and easy processing. It has excellent heat resistance and can improve the heat resistance of polycarbonate. performance, but the photoaging problem caused by its anti-ultraviolet radiation has not been solved. Therefore, in the anti-aging phenomenon of PC / ABS composite materials, it is basically to add ultraviolet absorbers and light stabilizers to the composite materials to solve the aging problem, but due to The dispersibility of UV absorbers and light stabilizers in the composite material system is low, making it necessary to add more UV absorbers and light stabilizers to play an anti-aging effect, but at the same time, the excessive addition of UV absorbers and light stabilizers It will reduce the impact resistance of the composite material and cause certain damage to the strength of the material.
