Abstract
The invention discloses a defoaming agent. The defoaming agent contains silanol sodium 10-40 parts, water glass 50-70 parts, polyvalent metal salt 10-20 parts, water 20-30 parts, fatty acid 1-3 parts and ethylene glycol 1-20 parts. A certain amount of polyvalent metal salt is added into the defoaming agent, so that the defoaming effect is good.
Description
Technical field
The present invention relates to defoamer, relate in particular to a kind of defoamer.
Background technology
Defoamer, is called again anti-foaming agent, in industrial process, can produce many harmful foams, need to add defoamer.Be widely used in removing the harmful foam producing in the industry production processes such as latex, textile sizing, food fermentation, biological medicine, coating, petrochemical industry, papermaking, industry cleaning link, before froth breaking, the kind of defoamer is a lot, organosiloxane, polyethers, silicon and ether grafting, containing amine, imines and amide-type, there is antifoaming speed faster, but the bubble time is longer, Applicable media is wider, and even harsh media environment is as the feature of high temperature, strong acid and highly basic.Defoaming effect has much room for improvement.
Summary of the invention
Object of the present invention provides a kind of defoamer, solves one or more in above-mentioned prior art problem.
According to an aspect of the present invention, provide a kind of defoamer, comprise multiple silicon shrinking alcohol sodium 10-40 part, waterglass 50-70 part, multivalent metal salt 10-20 part, water 20-30 part, aliphatic acid 1-3 part, ethylene glycol 1-20 part.
In some embodiments, mix all raw materials, at 100-150 ℃, dry 150min, obtains manufactured goods.
The present invention, by adding a certain amount of multivalent metal salt, makes defoaming effect better.
The specific embodiment
Embodiment 1:
A defoamer, comprises 10 parts, multiple silicon shrinking alcohol sodium, 50 parts of waterglass, 10 parts of multivalent metal salts, 20 parts, water, 1 part, aliphatic acid, 1 part of ethylene glycol.
Embodiment 2:
A defoamer, comprises 25 parts, multiple silicon shrinking alcohol sodium, 60 parts of waterglass, 15 parts of multivalent metal salts, 15 parts, water, 2 parts, aliphatic acid, 11 parts of ethylene glycol.
Embodiment 3:
A defoamer, comprises 40 parts, multiple silicon shrinking alcohol sodium, 70 parts of waterglass, 20 parts of multivalent metal salts, 30 parts, water, 3 parts, aliphatic acid, 20 parts of ethylene glycol.
During making, first multiple silicon shrinking alcohol sodium is mixed with waterglass, then add other raw materials, after stirring and filtering, dry 150min at 100-150 ℃, finish grinding obtains manufactured goods.
In sum, a kind of defoamer of making, by adding a certain amount of multivalent metal salt, makes defoaming effect better.Multivalent metal salt can be CaCl
2, MgCl
2or FeCl
2.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
