Abstract

The invention discloses an aqueous emulsion type non-silicon defoaming agent and a preparation method thereof. The aqueous emulsion type non-silicon defoaming agent comprises hydrocarbons, alcohols, amides, polyether, purified water and a thickening agent, wherein the hydrocarbons comprise cycloalkane, olefin and aromatic hydrocarbon, the alcohols comprise fatty alcohol and benzyl alcohol, the proportion of the cycloalkane is 13-23 parts, and the proportion of the olefin is 19-31 parts. According to the invention, the number of the hydrocarbons and the number of the alcohols are increased, so the aqueous emulsion type non-silicon defoaming agent is rich in composition during the production of the non-silicon defoaming agent; the obtained finished non-silicon defoaming agent has the characteristics of non-flammability, no explosion, no corrosion, high temperature resistance and the like during the use; and when the finished non-silicon defoaming agent is applied to products requiring defoaming, the defoaming agent disclosed by the invention can quickly permeate into liquid and quickly diffuse, so stubborn foams generated by various surfactants are eliminated, the defoaming agent can stably defoam under strong alkali and high temperature, the defect of residual silicon spots of silicon defoaming agents is better changed, and the practicability of the non-silicon defoaming agent h is stronger.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to an aqueous emulsion type non-silicon defoamer and a preparation method thereof. Background technique [0002] Defoamer is a substance that can reduce the surface tension of water, solution, suspension, etc., prevent foam formation, or reduce or eliminate the original foam. Defoamer is widely used, such as food industry, paper industry, water industry, etc. Treatment, oil extraction industry, printing and dyeing industry, paint industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, dairy industry, etc. Non-silicon defoamer is just a kind of defoamer type. [0003] The non-silicon defoamers currently on the market are relatively simple in composition when used, and cannot achieve the effect of quickly penetrating into the liquid during the application process, and then take a long time in the process of diffusion ...
