Document Type and Number:
WIPO Patent Application WO/2020/062970
Kind Code:
A1
Abstract:
Disclosed are an organosilicon modified polyether polyol as well as a preparation method therefor and an application thereof, relating to the technical field of polyurethane coating. The organosilicon modified polyether polyol has a structure comprising a structural unit consisting of organosiloxane and allyl glycidyl ether linked together by means of double-bond addition, and can be applied to the preparation of self-cleaning oily or waterborne polyurethane coatings. In the present invention, organosiloxane is introduced into the polyether polyol structure by means of double-bond addition; due to the unique umbrella structure, the polyether polyol can be better stretched; and the low surface energy of the siloxane in the coating can be migrated to the surface of the coating; thereby, the coating prepared with the modified polyether polyol has a surface with self-cleaning properties, and has good stability and strong adhesion.
