Abstract
The present invention discloses a kind of foam inhibitor and preparation method thereof, and by weight percentage, foam inhibitor includes：Polyglycol ether 25 40%；Expoxy propane 15 35%；Methyl butanol 8 15%；Lecithin 10 28%；Ethylenediamine 4 8%；Dimethylethyloxy butyric acid 3 12%；Aluminium hydroxide 10 30%；Catalyst 0.1 0.3%.60 80 minutes prepared foam inhibitors are stirred after above-mentioned substance is added.The present invention has excellent defoaming capacity and suds ability, there are stronger emulsification, dispersion and penetrating power, can in aqueous systems self-emulsifying, good stability, with lasting defoaming effect, it is nontoxic, it is cheap, with stronger froth breaking suds function, without mineral matter hydrocarbons, be conducive to environmental protection, and the compatibility of frothing media is good；Effect stability in Storage period.Its effect can rapidly and cleanly eliminate papermaking paint by pump, sieve and coating process in air knife, and scraping force produces a large amount of harmfulness foams when being coated with.
Description
Technical field
It is the present invention relates to the froth breaking in Chemical Manufacture, foam inhibitor field more particularly to a kind of new in paper technology
Type foam inhibitor.
Background technology
Consumption of the defoamer in paper industry is little, but its effect can not be ignored.In whole pulp and paper industry mistake
Cheng Zhong is the sequence of operations from after boiling blowing, such as washing, screening, bleaching, concentration, pulp feeding system, top sizing, coating, black
Liquid recovery etc., is influenceed by foam to some extent, the normal production of interference, declines paper quality, and life will be made when serious
Product cannot go on.
It is well known that the defoamer for possessing brokenly bubble function can eliminate foam, and foam in liquid can be prevented with foam inhibitor
Produce.But existing foam inhibitor is still present many deficiencies, it is impossible to meet the froth breaking and suds demand in paper technology.
Therefore, prior art has yet to be improved and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of foam inhibitor and preparation method thereof, purport
Cannot meet the bubble-related issues that elimination paper technology is present defoamer of the prior art is solved.
A kind of foam inhibitor, wherein：By weight percentage, including：
Polyglycol ether 25-40%；
Expoxy propane 15-35%；
Methyl butanol 8-15%；
Lecithin 10-28%；
Ethylenediamine 4-8%；
Dimethylethyloxy butyric acid 3-12%；
Aluminium hydroxide 10-30%；
Catalyst 0.1-0.3%.
A kind of preparation method of foam inhibitor as described above, wherein, including step：After each raw material is added into container, stir
Mix 60-80 minutes prepared foam inhibitor.
The present invention has excellent defoaming capacity and suds ability, there is stronger emulsification, dispersion and penetrating power, can be in water
Self-emulsifying in system, good stability is nontoxic with lasting defoaming effect, cheap, with stronger froth breaking suds work(
Can, without mineral matter hydrocarbons, be conducive to environmental protection, and the compatibility of frothing media is good；Effect stability in Storage period.Its effect
Papermaking paint can rapidly and cleanly be eliminated and produce a large amount of harm sex vesicles in air knife, when scraping force is coated with by pump, sieve and coating process
Foam.
Specific embodiment
The present invention provides a kind of foam inhibitor and preparation method thereof, to make the purpose of the present invention, technical scheme and effect more
Clear, clear and definite, the present invention is described in more detail below.It should be appreciated that specific embodiment described herein is only used to
The present invention is explained, is not intended to limit the present invention.
Embodiment 1：

Methyl butanol 10%；
Lecithin 11%；
Ethylenediamine 5%；
Dimethylethyloxy butyric acid 5%；
Aluminium hydroxide 15.8%；
Catalyst 0.2%.
The present invention also provides a kind of preparation method of foam inhibitor as described in Example 1, and it includes step：Each raw material is added
After adding to container, 60 minutes prepared foam inhibitors are stirred.
Embodiment 2：
A kind of foam inhibitor, wherein：By weight percentage, including：
Polyglycol ether 28%；
Expoxy propane 16%；
Methyl butanol 10%；
Lecithin 16%；
Ethylenediamine 5%；
Dimethylethyloxy butyric acid 5%；
Aluminium hydroxide 19.7%；
Catalyst 0.3%.
The present invention also provides a kind of preparation method of foam inhibitor as described in Example 2, and it includes step：Each raw material is added
After adding to container, 80 minutes prepared foam inhibitors are stirred.
The present invention has excellent defoaming capacity and suds ability, there is stronger emulsification, dispersion and penetrating power, can be in water
Self-emulsifying in system, good stability is nontoxic with lasting defoaming effect, cheap, with stronger froth breaking suds work(
Can, without mineral matter hydrocarbons, be conducive to environmental protection, and the compatibility of frothing media is good；Effect stability in Storage period.Its effect
Papermaking paint can rapidly and cleanly be eliminated and produce a large amount of harm sex vesicles in air knife, when scraping force is coated with by pump, sieve and coating process
Foam.
It should be appreciated that application of the invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or converted, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Shield scope.
