Title:
POLYURETHANE HAVING ANTI-ULTRAVIOLET PERFORMANCE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/242167
Kind Code:
A1
Abstract:
The present invention relates to the technical field of polyurethane polymer materials. Specifically disclosed are polyurethane having anti-ultraviolet performance and a preparation method therefor. In the present invention, triisopropyl borate, dihydric alcohol, and triatomic alcohol are used as raw materials, and a catalyst is added to prepare a chelating borate ester coupling agent containing a dihydroxy functional group, then the surface of a nano rare earth oxide is modified by using the chelating borate ester coupling agent containing the dihydroxy functional group to obtain a modified nano rare earth oxide, and in-situ polymerization is performed on the modified nano rare earth oxide and a polyester polyol or polyether polyol, polyisocyanate and a chain extender to obtain the polyurethane having the anti-ultraviolet performance. The polyurethane obtained in the present invention has a more durable, more stable and excellent anti-ultraviolet performance.
