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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
