Abstract
A polyether-silicone oil-potassium iodide antifoaming agent is disclosed. The antifoaming agent comprises 20-40% by weight of polyether, 20-35% by weight of dimethyl silicone oil, 10-25% by weight of water, 10-15% by weight of phenethylphenol polyoxypropylene polyoxyethylene ether and 10-15% by weight of potassium iodide. A preparing method of the antifoaming agent is also disclosed. Compared with traditional techniques, the antifoaming agent is economical, environmental friendly, safe and simple in preparation, and has functions of defoaming and inhibiting foams, a using amount of the antifoaming agent is reduced than that of other antifoaming agents, a production cost is greatly reduced and economic benefit is increased.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of polyether silicone oil KI defoamer and preparation method thereof.
Background technology
Defoamer is also called defrother or foamicide, can produce the foam that many impacts are produced in industrial processes, needs to add defoamer.Industrial defoaming agent mainly contains two aspect effects, froth breaking (abolishing unwanted bubbles that is that produce in industrial processes or that exist in product) and but bubble (suppressing to produce new foam in foaming system).Existing widely used defoamer is silicone based and the large series of polyethers two.Silicone based defoamer breaks that bubble power is strong, antifoaming speed is fast, but it is weak to press down bubble ability; Polyethers defoamer then defoaming capacity is weak, and a big gun ability is strong.And a lot of field, as papermaking, textile printing and dyeing, oil product processing, sewage disposal, oil exploitation and conveying etc., need defoamer have good froth breaking simultaneously and press down bubble function.At present, the domestic demand of defoamer to possessing froth breaking and press down bubble function simultaneously mainly realizes by import, and price is very expensive.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of polyether silicone oil KI defoamer.
Another object of the present invention is to the preparation method that above-mentioned polyether silicone oil KI defoamer is provided.
Technical scheme: in order to reach foregoing invention object, the present invention has specifically come like this: a kind of polyether silicone oil KI defoamer, comprises the component of following percentage by weight: the polyethers of 20 ~ 40%, the dimethicone of 20 ~ 35%, the water of 10 ~ 25%, the phenethyl phenol polyoxyethylene polyoxypropylene ether of 10 ~ 15% and 10 ~ 15% KI.
Wherein, preferably, by the component of following percentage by weight form 20 ~ 40% polyethers, 20 ~ 35% dimethicone, the water of 10 ~ 25%, the phenethyl phenol polyoxyethylene polyoxypropylene ether of 10 ~ 15% and 10 ~ 15% KI.
A kind of method preparing polyether silicone oil KI defoamer, each material is measured by formula, polyethers, dimethicone, phenethyl phenol polyoxyethylene polyoxypropylene ether and KI are stirred 1 ~ 2 hour at 40 ~ 50 DEG C, adds water after to be mixed and continue stirring 20 ~ 40 minutes and get final product.
Beneficial effect: the present invention is compared with conventional art, and economy, environmental protection, safety and preparation is simple, and have both froth breaking simultaneously and press down bubble function, use amount is also few compared with other defoamers, has greatly saved production cost, has improve economic benefit.
