Abstract
The invention discloses fire retardant anti-ultraviolet PC/ABS composition. The invention comprises components with the compounding ratio being as follows: 300 to 400 parts of PC resin, 450 to 550 parts of ABS resin, 100 to 120 parts of main fire retardant, 30 to 40 parts of auxiliary fire retardant, 20 to 30 parts of flexibilizer, 2 to 4 parts of light absorber, 2 to 3 parts of hindered amine light stabilizer, 10 to 20 parts of light screening agent, and 4 to 9 parts of antioxidant agent. The fire retardant anti-ultraviolet PC/ABS composition prepared by the technical proposal of the invention not only has the advantages of high rigidity, good anti-ultraviolet performance and size stability, but also has good processibility, thus the fire retardant anti-ultraviolet PC/ABS composition can be used as the applicable material of a plastic shelled circuit breaker and other low voltage apparatus casings.
Description
Technical field
The present invention relates to a kind of flame-proof ultraviolet-resisting PC/ABS composition, belong to the high polymer alloy field.
Background technology
Polycarbonate and ABS composition have good thermotolerance, impact and good processibility.This alloy is widely used in automobile component, household electrical appliance and electronic devices and components.The material of household electrical appliance and business automation equipment shell has fire-retardant requirement, adds halogen compounds usually so that flame retardant resistance to be provided.The fire-retardant PC/ABS composition of Halogen has excellent performance, but the adding of fire retardant descends the ultraviolet-resistent property of material greatly; Halogen-free flame retardant PC/ABS ultraviolet-resistent property is relatively good, but costs an arm and a leg, and over-all properties is defectiveness also.
Brominated epoxy resin is a kind of good brominated flame-retardant, the flame retarding efficiency height, and good with the consistency of material, the ultraviolet-resistent property of fire retardant material is good.The high-molecular weight brominated epoxy resin has very high thermotolerance, can be used for fire-retardant various engineering plastics.
