Title:
PREPARATION METHOD FOR ORGANIC SILICON ANTI-FOAMING AGENT FOR CATIONIC FOAMING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/001574
Kind Code:
A1
Abstract:
According to the present invention, the applicability of an anti-foaming agent in a cationic foaming system is improved by introducing cationic thickening agents in batches. A preparation method comprises: mixing silicone polyether, some cationic thickening agents, and some water to obtain a mixture M; and mixing the rest thickening agents with water to obtain a mixture N; and emulsifying an anti-foaming agent active matter and an emulsifier mixture, and then respectively adding the mixture A and the mixture B to finally obtain an organic silicon anti-foaming agent. The anti-foaming agent has long-lasting anti-foaming performance in the cationic foaming system, and does not cause problems such as precipitation.
