Abstract

The invention discloses a defoaming agent with a high defoaming speed. The defoaming agent is prepared from the following raw materials in parts by weight: 850-900 parts of water, 20-30 parts of polyisobutylene, 3-4 parts of sodium tripolyphosphate, 200-250 parts of dimethyl silicone oil, 200-250 parts of tributyl phosphate, 35-50 parts of emulsifier, 50.6-62.5 parts of mannitol, 40-50 parts of sodium stearate, 58.5-62.5 parts of diatomite, 5-7 parts of sodium hydroxymethylcellulose, 3-5 parts of thickener, 50-60 parts of polystyrene, 30-50 parts of polyether and 3-5 parts of dispersant, 30-50parts of linear grease, 65-85 parts of liquid paraffin and 6-8 parts of glycerol. The defoaming agent has beneficial effects of high surface activity, strong defoaming power, small use level, low cost and the like. The defoaming agent has characteristics of good dispersibility and rapid defoaming, and being non-toxic, odorless, and conducive to production safety.

Description

technical field [0001] The invention relates to the technical field of defoaming agents, in particular to a defoaming agent with fast defoaming speed and a preparation method thereof. Background technique [0002] Defoamer, also known as defoamer, is an additive that reduces surface tension during processing, inhibits foam generation or eliminates foam that has already occurred. [0003] Many harmful foams are often produced in the process of industrial production, which requires defoamers to eliminate and suppress them. However, when the existing defoamers are used in the processing of very bubbly solutions, they still have the problems of slow defoaming speed and short foam suppression time, resulting in poor defoaming effect, thereby affecting the normal production of the industry. [0004] To sum up, how to solve the problem of slow defoaming speed is an urgent technical problem to be solved at present. Contents of the invention [0005] The technical task of the pre...
