Description
Technical field
The invention belongs to defoaming agent technical field, it is related to a kind of chemical assistant and preparation method thereof, specifically relates to one
Novel defoaming agent of kind and preparation method thereof.
Background technique
In the industrial processes such as synthetic latex, papermaking, weaving, food, fermentation, medicine, many bubbles are often generated
Foam or even harmful foam, affect normal production, this just needs to be eliminated or inhibited with defoaming agent.Disappear both at home and abroad at present
Infusion is many kinds of.Mainly have: grease type defoaming agent, several major class such as organic silicon defoaming agent and polyethers defoaming agent.
Wherein the defoaming agent of grease type is cheap, although still largely using currently on the market, it steeps dense form
The elimination ability of foam is poor.Grease type defoaming agent antifoam performance is low, and usual dosage is the 20- of organic silicon and polyethers defoaming agent
60 times；Organic silicon defoaming agent generally comprises dimethyl silicone polymer etc., though this kind of defoaming agent defoaming effectiveness is high, foam inhibition effect
Fruit is poor.
Polyethers defoaming agent mainly has straight-chain polyether etc., and foam inhibition ability is strong, is the leading defoaming of current fermentation industry application
Agent, but its antifoaming speed is slower than organic silicon defoaming agent, " polyethers 330 ", " PPG ", " GP " polyethenoxy ether, due to they
The end of the chain is hydrophobic chain, is not easy to disperse in fermentation liquid, causes that antifoaming speed is slow, does not catch up with the speed of fermentation blistering, is influenced
Defoaming effect.
And as " GPE ", " PPE ", " 3010 ", polyoxypropylene ethylene oxide glycerin ether, several defoaming agents are being defoamed earlier above
Though had been improved in performance, because hydrophilic chain polyoxyethylene chain have hypotoxicity, in fermenting and producing, have hinder thalli growth with
And the phenomenon that killing a small amount of somatic cells, occurs, and there are problems that influencing fermentation efficiency to a certain extent.
Summary of the invention
The present invention is solves the problems, such as above technical, and design provides a kind of novel defoaming agent and preparation method thereof, prepares
Defoaming agent by with emulsifier AEO sealing end, make segment both ends become to do the hydrophobic chain blocked with emulsifier AEO, between centre is
Every the block polymer molecules of hydrophilic chain, while added with lanolin, silicone oil, defoaming dynamics is strengthened, antifoaming speed is improved, is disappeared
In addition to toxicity improves production efficiency so that antifoaming speed improves 40-60 times than other polyether-type defoaming agents.
In order to reach above-mentioned technical effect, the present invention takes following technical scheme: a kind of defoaming agent, by total weight hundred
Divide than being 100% calculating, including following components in percentage by weight: polyoxypropylene ethylene oxide glycerin ether 79.5%-90%, cream
Agent AEO 0.6%-2.1%, silicone oil 4%-7.7%, lanolin 5%-9.5%, stable and uniform agent 0.4%-1.2%.
More preferably defoaming agent is 100% calculating, including following components in percentage by weight by total weight percent: poly-
Oxypropylene ethylene oxide glycerin ether 85%, emulsifier AEO 2%, silicone oil 5%, lanolin 7%, stable and uniform agent 1%.
Wherein, stable and uniform agent is oleamide.
Emulsifier fatty alcohol polyoxyethylene ether (AEO) is one of AEO-3, AEO-7, AEO-9 or a variety of.
Silicone oil is dimethicone, diethyl silicone oil, diphenyl silicone oil, hydrogen methyl-silicone oil, hydrogen ethyl silicon oil, hydrogen phenyl silicon
The mixture of one or more of oil, amido silicon oil.
Each raw material in the present invention is the conventional products sold in the market.
A kind of preparation method producing above-mentioned defoaming agent, method includes the following steps: successively successively adding to reaction unit
Enter polyoxypropylene ethylene oxide glycerin ether, emulsifier, lanolin, stable and uniform agent, silicone oil；It is every a kind of component is added all to be added
Thermal agitation.
It is further method includes the following steps:
(1) polyoxypropylene ethylene oxide glycerin ether is put into reaction unit, is heated and is stirred, mixing time 0.5-
1.5h, while being heated to 35-40 degrees Celsius；
(2) on the basis of 35-40 degrees Celsius of temperature, continue that emulsifier AEO is added to reaction unit, mixing time is
0.5-1.5h；
(3) lanolin, mixing time 1-2h are put into reaction unit；
(4) stable and uniform agent is put into reaction unit, and reaction unit is heated up to 75-85 degrees Celsius at this time, is stirred
It mixes, mixing time 1-3h；
(5) on the basis of 75-85 degrees Celsius of temperature, silicone oil is put into reaction unit, keeps temperature 75-85 Celsius
Degree, is stirred, and mixing time 2-3h stops heating after homogeneous, naturally cools to room temperature to get the defoaming agent is arrived；
Entire reaction process speed of agitator is 60-90r/min.
Further, method includes the following steps:
(1) in the reaction unit with heating and stirring function, polyoxypropylene ethylene oxide glycerin ether is put into, heats and stirs
It mixes, speed of agitator 70r/min, mixing time 1h, while being heated to 40 degrees Celsius；
(2) on the basis of 40 degrees Celsius of temperature, emulsifier AEO is put into reaction unit, is stirred, speed of agitator
For 70r/min, mixing time 1h；
(3) lanolin is put into reaction unit, is stirred, speed of agitator 70r/min, mixing time 1.5h；
(4) stable and uniform agent is put into reaction unit, and reaction unit is heated up to 80 degrees Celsius at this time, is stirred,
Speed of agitator is 70r/min, and mixing time 2h makes it sufficiently combine closely, is homogeneous；
(5) on the basis of 80 degrees Celsius of temperature, silicone oil is put into reaction unit, is kept for 85 degrees Celsius of temperature, is carried out
Stirring, speed of agitator 70r/min, mixing time 2.5h stop heating after homogeneous, naturally cool to room temperature to get to should
Defoaming agent.
The invention has the benefit that
(1) defoaming agent becomes polyoxypropylene ethylene oxide glycerin ether segment both ends with emulsification with emulsifier AEO sealing end
Agent AEO does the hydrophobic chain blocked, and centre is the block polymer molecules for being spaced hydrophilic chain, and effect strengthens defoaming dynamics, mentions
High antifoaming speed, eliminates toxicity.
(2) the distinctive fatty acid of lanolin, collagen, property are stablized, and preferably effectively continue lengthening defoaming and continue
Pot life.
(3) for silicone oil due to its small molecule, surface tension is small, high surface activity, and defoaming power is strong, it is simultaneous to all bubble systems
Have the function of foam inhibition, brokenly bubble.
(4) defoaming agent being prepared has good stability, defoaming intensity height, while eliminating hypotoxicity, and to hair
Mycelia during ferment provides nutrient, and antifoaming speed improves 40-60 times than other polyether-type defoaming agents.In papermaking, hair
It is eliminated in the industries such as ferment, food, medicine and inhibits foam that there is excellent using effect, be used especially in chemical fibre industry, more
The wretched insufficiency of organic silicone oil defoaming agent is mended.
