Abstract
The invention discloses a polyether-siloxane isooctanol antifoaming agent, which comprises the following ingredients (by weight): 20-40% of polyether, 20-35% of dimethicone, 10-25% of water, 10-15% of diphenethyl diphenol polyoxyethylene ether and 10-15% of isooctyl alcohol. Meanwhile, the invention also discloses a preparation method of the above antifoaming agent. In comparison with a traditional technology, the polyether-siloxane isooctanol antifoaming agent is economic, environmentally-friendly and safe, is simple to prepare, has both antifoaming and foam inhibition functions and is used less than other antifoaming agents. Production costs are greatly saved, and economic benefit is raised.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of polyether silicone oil isooctyl alcohol defoamer and preparation method thereof.
Background technology
Defoamer is also called defrother or foam-killing agent, 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 production 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 isooctyl alcohol defoamer.
Another object of the present invention is to the preparation method that above-mentioned polyether silicone oil isooctyl alcohol 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 isooctyl alcohol defoamer, comprises the component of following weight percent: the polyethers of 20 ~ 40%, the dimethyl silicone oil of 20 ~ 35%, the water of 10 ~ 25%, the diphenylethyl diphenol Soxylat A 25-7 of 10 ~ 15% and 10 ~ 15% isooctyl alcohol.
Wherein, preferably, by the component of following weight percent form 20 ~ 40% polyethers, 20 ~ 35% dimethyl silicone oil, the water of 10 ~ 25%, the diphenylethyl diphenol Soxylat A 25-7 of 10 ~ 15% and 10 ~ 15% isooctyl alcohol.
A kind of method preparing polyether silicone oil isooctyl alcohol defoamer, each material is measured by formula, polyethers, dimethyl silicone oil, diphenylethyl diphenol Soxylat A 25-7 and isooctyl alcohol 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, usage quantity is also few compared with other defoamers, has greatly saved production cost, has improve economic benefit.
