Abstract
The invention discloses a polyether silicone oil benzyl dimethyl phenol polyoxyethylene ether defoaming agent. The polyether silicone oil benzyl dimethyl phenol polyoxyethylene ether defoaming agent is prepared from, by weight, 20%-40% of polyether, 20%-35% of dimethyl silicon oil, 10%-25% of water, 10%-15% of paraffin and 10%-15% of benzyl dimethyl phenol polyoxyethylene ether. The invention further discloses a preparation method of the defoaming agent. Compared with the traditional art, the polyether silicone oil benzyl dimethyl phenol polyoxyethylene ether defoaming agent is economical, environmentally friendly, safe and easy to prepare, the defoaming function and the foam inhibiting function are achieved at the same time, the use amount is smaller than that of other defoaming agents, production cost is greatly reduced, and economic benefits are increased.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of polyether silicone oil benzyl dimethyl phenol polyethenoxy ether defoaming agent 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 benzyl dimethyl phenol polyethenoxy ether defoaming agent.
Another object of the present invention is to the preparation method that above-mentioned polyether silicone oil benzyl dimethyl phenol polyethenoxy ether defoaming agent 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 benzyl dimethyl phenol polyethenoxy ether defoaming agent, comprises the component of following percentage by weight: the polyethers of 20 ~ 40%, the dimethicone of 20 ~ 35%, the water of 10 ~ 25%, the paraffin of 10 ~ 15% and 10 ~ 15% benzyl dimethyl phenol polyethenoxy ether.
Wherein, preferably, by the component of following percentage by weight form 20 ~ 40% polyethers, 20 ~ 35% dimethicone, the water of 10 ~ 25%, the paraffin of 10 ~ 15% and 10 ~ 15% benzyl dimethyl phenol polyethenoxy ether.
A kind of method preparing polyether silicone oil benzyl dimethyl phenol polyethenoxy ether defoaming agent, each material is measured by formula, polyethers, dimethicone, paraffin and benzyl dimethyl phenol polyethenoxy ether 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.
