Abstract

The invention relates to a composite organic-silicon liquid defoaming agent. The composite organic-silicon liquid deforming agent is composed of the following components in parts by weight: 12-18 parts of liquid organic silicon active matter, 10-20 parts of an emulsifying agent, 30-35 parts of a stabilizer, 1-5 parts of hydrophobic particles and 42-45 parts of a surface modifier, wherein the organic silicon defoaming active matter is one of or a compound of more than one of methyl silicone oil, methyl phenyl silicone oil, ethyl silicone oil, polyether modified silicone oil and dimethyl siloxane hydrolysate; an emulsifying auxiliary is one of or a compound of more than one of a non-ionic surfactant, alkylphenol polyoxyethylene ether, polyoxyethylene ether and fatty alcohol polyoxyethylene ether; the stabilizer is starch; the hydrophobic particles are one of or a compound of more than one of anhydrous sodium sulfate, alum and white carbon black; and the surface modifier is one of triethanolamine and n-octyl alcohol or a compound of the two. The composite organic-silicon liquid defoaming agent provided by the invention not only can play good defoaming effect in an application process,but also can maintain good stability and persistence in various service environments.

Description

technical field [0001] The invention relates to the field of fine chemical additives, in particular to a composite organosilicon liquid defoamer. Background technique [0002] Silicone defoaming agent has rapid defoaming and long-lasting foam suppression; good dispersibility, high temperature resistance, acid and alkali resistance, electrolyte resistance, shear resistance, good compatibility with various dyes and chemicals, no oil drift, no silicon spots; Safe and non-toxic, in line with environmental protection requirements; stable quality and other characteristics, it is the most widely used system in the field of defoamers. Silicone defoamers are commonly used in the market as aqueous phase emulsion type and solvent type; the aqueous phase emulsion type has the characteristics of good storage stability, convenient transportation, and easy use, and can be prepared into a compound type of antifoaming agent of various organosilicon compounds. foaming agent.
