Abstract
The present invention relates to chemicals technical fields, especially a kind of aqueous defoamer, including 25 ~ 45 parts of dimethicone, 3 ~ 8 parts of hydroxypropyl methyl cellulose, 2 ~ 20 parts of white carbon black, 1 ~ 2 part of catalyst, 5 ~ 10 parts of dispersing agent, 6 ~ 12 parts of polyoxyethylene, the defoaming agent has good antifoam performance and stability, is widely used.
Description
Technical field
The present invention relates to chemicals technical field, especially a kind of aqueous 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 existing unconspicuous deficiency of defoaming agent effect, the present invention provides a kind of aqueous defoamers.
The technical solution adopted by the present invention to solve the technical problems is: a kind of aqueous defoamer, including dimethicone
25 ~ 45 parts, 3 ~ 8 parts of hydroxypropyl methyl cellulose, 2 ~ 20 parts of white carbon black, 1 ~ 2 part of catalyst, 5 ~ 10 parts of dispersing agent, polyoxyethylene 6
~ 12 parts, which has good antifoam performance and stability, is widely used.
The invention has the advantages that the defoaming agent has good antifoam performance and stability, it is widely used.
Specific embodiment
Below by specific embodiment, invention is further explained.
Embodiment 1
A kind of aqueous defoamer, counts based on parts by weight, 28 parts of dimethicone, 4 parts of hydroxypropyl methyl cellulose, white carbon black 5
Part, 1 part of catalyst, 6 parts of dispersing agent, 8 parts of polyoxyethylene.
Embodiment 2
A kind of aqueous defoamer, counts based on parts by weight, 33 parts of dimethicone, 5 parts of hydroxypropyl methyl cellulose, white carbon black 7
Part, 1 part of catalyst, 8 parts of dispersing agent, 8 parts of polyoxyethylene.
Embodiment 3
A kind of aqueous defoamer, counts based on parts by weight, 35 parts of dimethicone, 6 parts of hydroxypropyl methyl cellulose, white carbon black 9
Part, 2 parts of catalyst, 8 parts of dispersing agent, 9 parts of polyoxyethylene.
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.
