Abstract

The invention discloses environment-friendly organic silicon defoamer. The environment-friendly organic silicon defoamer is prepared from, by weight, 30-50 parts of dimethicone, 10-30 parts of silicon dioxide, 0.3-0.5 part of stearic acid, 3-5 parts of soybean oil, 6-10 parts of soya bean lecithin, 1-3 parts of glycerol monostearate, 1.3-1.5 parts of microcrystalline wax, 1-3 parts of Twain-60, 3-5 parts of silicone emulsion, 0.3-0.8 part of agar, 0.3-0.5 part of butyl acrylate, 0.3-0.5 part of isooctyl maleate, 2-4 parts of nonyl phenol polyoxyethylene ether, 0.8-1.7 parts of straw powder, 2.3-3.6 parts of coconut shell, and 10-20 parts of water.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to an environment-friendly organic silicon defoamer. Background technique [0002] In the process of industrial production, if there is a large amount of foam, it will bring a lot of troubles to the production process, such as the production capacity will be greatly limited; cause waste of raw materials and products; affect product quality; pollute the environment, etc. Therefore, how to effectively control the foam in the production process has become the focus of researchers. Nowadays, defoamers are generally used to eliminate foam generated in industrial production. [0003] Defoamers commonly used in industry can generally be divided into three categories: organic defoamers, silicone defoamers and polyether defoamers. Silicone defoamer is composed of dimethyl silicone oil and SiO2 in a certain proportion. The defoamer made in this way has the characteristics of ins...
