Problems solved by technology

PC itself has a certain flame retardancy (oxygen index is 21% to 24%), but in TVs, computers, transformer coils, auto parts, building materials and other applications with high flame retardancy and high impact resistance requirements, The flame retardancy and impact resistance of polycarbonate are still insufficient, so it is necessary to develop an environmentally friendly flame-retardant and impact-resistant polycarbonate composite material to meet its market demand

Abstract

The invention discloses an environment-friendly flame-retardant impact-resistant polycarbonate composite material and a preparation method thereof. The environment-friendly flame-retardant impact-resistant polycarbonate composite material is prepared from a bisphenol A polycarbonate resin, polyetheretherketone, zinc stearate, magnesium stearate, polytetrafluoroethylene micropowder, aluminum metaphosphate, trichloroethyl phosphate, nano titanium carbide, tributyl citrate, antimony glance powder, hydrated magnesium silicate micropowder, pentaerythritol tetra[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], nano calcium carbonate, attapulgite, graphene, 2,2'-dihydroxy-4,4'-dimethoxy diphenyl ketone, ethylene bis stearamide and the like. The nano calcium carbonate, nano titanium carbide, hydrated magnesium silicate micropowder and the like are sufficiently dispersed in the plastic resin to enhance the weather resistance, mechanical properties and other properties of the material. The antimony glance powder, aluminum metaphosphate, polyetheretherketone, trichloroethyl phosphate and other reinforcing fillers and modifying materials are added to enhance the flame retardancy, impact resistance and other properties of the material.

Description

technical field [0001] The invention relates to a polycarbonate material, in particular to an environment-friendly flame-retardant and impact-resistant polycarbonate composite material and a preparation method thereof. Background technique [0002] Polycarbonate 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 the aliphatic and aliphatic-aromatic The mechanical properties of polycarbonate are low, so its application in engineering plastics is limited. At present, only aromatic polycarbonate has been industrialized. Polycarbonate has become the fastest growing general-purpose project among the five engineering plastics. plastic. Polycarbonate PC has good light transmission, impact resistance, UV radiation resistance and dimensional stability of its products and good molding processing performance, so it is widely...
