Abstract
The present invention relates to chemicals technical fields, especially a kind of polyether antifoam agent, including 120 ~ 150 parts of polyglycol ether, 65 ~ 125 parts of ethylene oxide, 25 ~ 40 parts of butanol, 25 ~ 55 parts of lecithin, 45 ~ 80 parts of magnesium hydroxide, 20 ~ 35 parts of wollastonite, the defoaming agent possesses preferable defoaming and foam inhibition ability, stability is good, and effect is lasting and environmental protection.
Description
Technical field
The present invention relates to chemicals technical field, especially a kind of polyether antifoam agent.
Background technique
Defoaming agent, also referred to as defomaing agent are that surface tension is reduced in food processing process, and foam is inhibited to generate or eliminate
Generate the food additives of foam.China, which is permitted workable defoaming agent, the fatty acid ester compounded object of silicone emulsion, higher alcohols, polyoxy
Ethylene polyoxypropylene pentaerythrite ether, polyoxyethylene polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether and polyoxyethylene polyoxypropylene
7 kinds of glycerin ether, dimethyl silicone polymer etc..Defoaming agent is mostly liquid compound product, is broadly divided into three classes: mineral oils, organic
Silicon class, polyethers.Mineral oil defoaming agent is usually made of carrier, activating agent etc..Organic silicon defoaming agent generally comprises poly- two
Methylsiloxane etc..Organic silicon defoaming agent dissolubility is poor, at normal temperature have antifoaming speed quickly, foam inhibition it is preferable, but
High temperature issues layer estranged, antifoaming speed compared with the features such as slow, foam inhibition is poor.
The problems such as generally existing defoaming of defoaming agent currently on the market is slow, and defoaming effect is undesirable.
Summary of the invention
In order to overcome the shortcomings of that existing defoaming agent stability is poor, the duration is short, the present invention provides a kind of polyethers to disappear
Infusion.
The technical solution adopted by the present invention to solve the technical problems is: a kind of polyether antifoam agent, including polyglycol ether
120 ~ 150 parts, 65 ~ 125 parts of ethylene oxide, 25 ~ 40 parts of butanol, 25 ~ 55 parts of lecithin, 45 ~ 80 parts of magnesium hydroxide, wollastonite 20
~ 35 parts, which possesses preferable defoaming and foam inhibition ability, and stability is good, and effect is lasting and environmental protection.
The invention has the advantages that possessing preferable defoaming and foam inhibition ability, stability is good, and effect is lasting and environmental protection.
Specific embodiment
Below by specific embodiment, invention is further explained.

Embodiment 2
A kind of polyether antifoam agent, counts based on parts by weight, 128 parts of polyglycol ether, 80 parts of ethylene oxide, 33 parts of butanol, lecithin
32 parts of rouge, 55 parts of magnesium hydroxide, 28 parts of wollastonite.
Embodiment 3
A kind of polyether antifoam agent, counts based on parts by weight, 135 parts of polyglycol ether, 85 parts of ethylene oxide, 37 parts of butanol, lecithin
35 parts of rouge, 60 parts of magnesium hydroxide, 32 parts of wollastonite.
One embodiment of the present invention has been described in detail above, but the content is only that the present invention is preferably implemented
Example, should not be considered as limiting the scope of the invention.It is all according to all the changes and improvements made by the present patent application range
Deng should still be within the scope of the patent of the present invention.
