Abstract
The present invention relates to chemicals technical fields, especially a kind of paper grade (stock) defoaming agent, including 120 ~ 300 parts of fatty acid, 50 ~ 80 parts of fatty acid amide, 60 ~ 95 parts of aliphatic ester, 3 ~ 9 parts of diglycol monotertiary olein, 55 ~ 85 parts of allyl alcohol, 2 ~ 8 parts of stearmide, 45 ~ 80 parts of sodium hydroxide, 1 ~ 2 part of dimethicone, the defoaming agent has excellent foam inhibition and defoaming capacity, it is low in cost, possess preferable economy and society value.
Description
Technical field
The present invention relates to chemicals technical field, especially a kind of paper grade (stock) defoaming 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 effect is poor, the present invention provides a kind of paper grade (stock) defoaming agents.
The technical solution adopted by the present invention to solve the technical problems is: a kind of paper grade (stock) defoaming agent, including fatty acid 120
~ 300 parts, it is 50 ~ 80 parts of fatty acid amide, 60 ~ 95 parts of aliphatic ester, 3 ~ 9 parts of diglycol monotertiary olein, 55 ~ 85 parts of allyl alcohol, hard
2 ~ 8 parts of acyl amine, 45 ~ 80 parts of sodium hydroxide, 1 ~ 2 part of dimethicone, the defoaming agent have excellent foam inhibition and defoaming capacity,
It is low in cost, possess preferable economy and society value.
The invention has the advantages that the defoaming agent has excellent foam inhibition and defoaming capacity, and it is low in cost, possess preferably
Economy and society value.
