Abstract
The present invention relates to chemicals technical fields, especially a kind of organic silicon defoamer, including 150 ~ 250 parts of dimethicone, 25 ~ 50 parts of silica, 100 ~ 200 parts of hydroxy silicon oil, 80 ~ 180 parts of tributyl phosphate, 60 ~ 80 parts of potassium hydroxide, the defoaming agent has excellent antifoam performance, have a wide range of application, it is environmentally protective, with more high temperature resistant, cold-resistant, ageing-resistant performance.
Description
Technical field
The present invention relates to chemicals technical field, especially a kind of organic silicon defoamer.
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 effect is unobvious, not environmentally, the present invention provides a kind of organosilicons to disappear
Infusion.
The technical solution adopted by the present invention to solve the technical problems is: a kind of organic silicon defoamer, including dimethyl-silicon
150 ~ 250 parts of oil, 25 ~ 50 parts of silica, 100 ~ 200 parts of hydroxy silicon oil, 80 ~ 180 parts of tributyl phosphate, potassium hydroxide 60 ~
80 parts, which has excellent antifoam performance, has a wide range of application, environmentally protective, with more high temperature resistant, resists cold, ageing-resistant
Performance.
The invention has the advantages that the defoaming agent has excellent antifoam performance, have a wide range of application, it is environmentally protective, more
With high temperature resistant, cold-resistant, ageing-resistant performance.
Specific embodiment
Below by specific embodiment, invention is further explained.
