Abstract
The invention discloses a defoaming agent, which comprises the following ingredients in parts by mass: 10-70 parts of water, 32-35 parts of dimethicone, 30-35 parts of polyether modified silicone oil, 20-25 parts of an emulsifier, and 0.5-0.8 part of a dispersing agent, wherein fatty alcohol polyoxyethylene ether is adopted as the emulsifier, the flashing point of the dimethicone is 295-300DEG C, and the dispersing agent is one of or the mixture of any two of silicon dioxide, acrylate copolymer and polymethylsilane in any ratio. The defoaming agent not only is economic, environmentally friendly, safe, and simple to prepare, and has good stability and excellent defoaming and foaming inhibition effects, and the usage amount of the defoaming agent is only 0.1-0.12% by mass of that of a to-be-defoamed material.
Description
Technical field
The present invention relates to a kind of defoamer.
Background technology
The effect of industrial defoaming agent mainly contains two aspects: froth breaking (abolish in industrial processes, produce or product in harmful foam of existing) and press down bubble (suppressing to produce new foam in foaming system).Existing widely used defoamer mainly contains the silicone based and large series of polyethers two.The broken bubble power of silicone based defoamer is strong, antifoaming speed is fast, but a little less than pressing down bubble ability; Polyethers defoamer a little less than froth breaking ability, presses down bubble ability strong.But a lot of fields, as papermaking, textile printing and dyeing, oil product processing, sewage disposal, oil exploitation and conveying etc., need defoamer to possess fine froth breaking simultaneously and press down bubble function.At present, domestic the demand of defoamer that possesses froth breaking simultaneously and press down bubble function is mainly realized by import, price is very expensive.
Summary of the invention
The invention provides a kind of defoamer.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of defoamer, comprise water 10-70 part, dimethicone 32-35 part, polyether modified silicon oil 30-35 part, emulsifying agent 20-25 part, dispersant 0.5-0.8 part, described emulsifying agent is AEO, described dimethyl-silicon oil flash is 295-300 ℃, and described dispersant is the mixture of one or more any proportionings in silica, acrylic copolymer and polymethyl silicane, and described umber is mass fraction.
Described defoamer also comprises thickener 3-5 part, and described umber is mass fraction.
Described thickener is polyvinylether or polyacrylate.
Described emulsifying agent is peregal A-20.
Defoamer of the present invention, not only economy, environmental protection, safety, preparation are simple, and have good stability and good froth breaking presses down bubble effect, and its consumption is only for treating the 0.1-0.12% of quality consumption of froth breaking material.
The specific embodiment
Embodiment 1
A kind of defoamer, comprises 10 parts, water, 35 parts of dimethicones, 30 parts of polyether modified silicon oils, 25 parts of emulsifying agents, 0.5 part of dispersant, described emulsifying agent is peregal A-20, described dimethyl-silicon oil flash is 295-300 ℃, and described dispersant is silica, and described umber is mass fraction; Above-mentioned material is mixed and obtains defoamer.
Embodiment 2
A kind of defoamer, comprises 70 parts, water, 32 parts of dimethicones, 35 parts of polyether modified silicon oils, 20 parts of emulsifying agents, 0.8 part of dispersant, described emulsifying agent is peregal A-20, described dimethyl-silicon oil flash is 295-300 ℃, and described dispersant is silica, and described umber is mass fraction; Above-mentioned material is mixed and obtains defoamer.
