Abstract
Disclosed is an impact-resistant and aging-resistant reflective plastic applied to an automobile, which is prepared by copolymerizing of polyether polyol, 4,4,4-triphenylmethane triisocyanate and a benzimidazole derivative modified ZnS-mesoporous silica composite, the benzimidazole derivative modified ZnS-mesoporous silica composite is a ZnS-mesoporous silica composite modified by an anti-aging agent and a silane coupling agent KH-560, the ZnS-mesoporous silica is obtained by mixing an amphoteric surfactant, zinc chloride, and γ-aminopropyltrimethoxysilane uniformly, then reacting in ethyl orthosilicate, and calcining with hydrogen sulfide. In the present disclosure, by dispersing zinc sulfide in the pores of mesoporous carbon dioxide, chemical grafting 2-(2-hydroxy-5-aminophenyl)benzimidazole as a bridge onto isocyanate, and then polymerizing into polyurethane, which can improve the reflective performance and aging resistance of polyurethane, and improve the abrasion resistance and impact resistance.
