Title:
ORGANIC SILICON DEFOAMING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2021/254170
Kind Code:
A1
Abstract:
The present invention relates to an organic silicon defoaming composition. Firstly, a vinyl polyorganosiloxane is reacted with a hydrogen-containing polyorganosiloxane at a certain molar ratio, a reaction control agent is then added dropwise, and finally, the polymer is mixed with a silicon resin and a filler such as silicon dioxide in order to prepare the organic silicon defoaming composition. The defoaming composition is prepared using a method of dropwise adding a reaction control agent. The reaction is mild and easy to control, the problems that the reactants are prone to gelling, the active substance is unstable in storage, etc. are solved, and the prepared active substance has a good and durable defoaming performance in a high-temperature strong base system.
