Abstract
A powerful defoaming agent is prepared by adding polyoxypropylene glycerol ether or polyoxypropylene oxyethyl glycerol ether or a mixture of the polyoxypropylene glycerol ether and the polyoxy oxyethyl glycerol ether into dimethyl silicone oil and stearic acid, wherein the specific proportions of the components are as follows (weight ratio): 0.5-5% of dimethyl silicone oil, 0.5-3% of stearic acid, 0-99% of polyoxypropylene glycerol ether and 0-99% of polyoxypropylene polyoxyethylene glycerol ether. The invention has strong defoaming force, long foam inhibition time and better effect than other defoamers although the dosage is less.
Description
The present invention relates to a kind of foam mortifier.
Employed defoamer kind is a lot of in industrial production at present, as the defoamer that is used for oily medium has dimethicone and polyoxyethyl propyl glycerin ether, this polyoxyethyl propyl glycerin ether also can be used for the defoamer of aqueous medium, and the defoamer that is used for aqueous medium also has the mixture of polyoxyethyl propyl polyoxy ethyl glycerin ether and dimethicone and emulsifying agent, polyoxyethyl propyl polyoxy ethyl glycerin ether and polyoxyethyl propyl glycerin ether catch on the bubble speed all not good enough, so consumption is more, generally 0.08% to product cost is increased, toxicity increases, can cause that antibiotic production is tired reduces or food fermentation production (as monosodium glutamate) is produced acid and reduced, clean upward very difficult the use because of catching the bad industry of bubble performance again, though dimethicone is good defoamer in oily medium, but can not be directly used in water base froth breaking owing to it is water insoluble, it can only be used after with emulsifying agent emulsification, but its stability is bad, wall built-up and influence extraction effect during use, and it is also relatively poor to press down the bubble ability.
In view of above-mentioned weak point of the prior art the object of the present invention is to provide a kind of consumption few, the froth breaking ability can be used for the defoamer of oil-water media by force.
Purpose of the present invention can realize by following measure:
A kind of mighty defoamer, it contains dimethicone, polyoxyethyl propyl polyoxy ethyl glycerin ether and/or polyoxyethyl propyl glycerin ether, it is characterized in that: it also contains stearic acid, the concrete ratio of these components following (weight ratio):
Dimethicone 0.5～5%
Stearic acid 0.5～3%
Polyoxyethyl propyl glycerin ether and/or polyoxy
Propyl group polyoxy ethyl glycerin ether 93～99%
The present invention adds polyoxyethyl propyl glycerin ether or polyoxyethyl propyl polyoxy ethyl glycerin ether or the two mixture in dimethicone and stearic acid.
One of main component of the present invention is a dimethicone, and its chemical structural formula is:
It is a kind of defoamer commonly used, its ratio shared in whole defoamer has certain scope, if consumption very little, then do not reach the effect of rapid froth breaking, if consumption does not only increase the cost that defoaming effect also can increase product on the contrary too much, general select 0.5～5% more suitable, and preferably 2%.Another Main Ingredients and Appearance of defoamer of the present invention is a stearic acid, and its molecular formula is CH
3(CH
2)
16COOH.Its proportion is less, generally all float on the dielectric surface, it has the autohemagglutination effect, himself static can produce polarization force foam is destroyed, its shared ratio in defoamer also has certain limit, if consumption does not reach the effect of froth breaking very little, and consumption is too many, defoamer is white in color influences its outward appearance, general select 0.5～3% more suitable, preferably 2.5%, defoamer of the present invention is except that containing above-mentioned two kinds of materials, remaining composition can all be the polyoxyethyl propyl glycerin ether, and its molecular formula is (CH
3OH)
2CHOHCH
3(OCH
2CH)
mMolecular weight is between 4000～5000, and it also is the defoamer of using always, and it mainly acts on is to suppress the foam growth; Also can all be polyoxyethyl propyl polyoxy ethyl glycerin ether, its molecular formula be (CH
3OH)
2CHOHCH
3(OCH

m(OCH

2)
nMolecular weight is between 3000～4000, and it also is the defoamer of using always, and it mainly acts on is the moment froth breaking; Can also be the mixture of polyoxyethyl propyl glycerin ether and polyoxyethyl propyl polyoxy ethyl glycerin ether, both can be that arbitrary proportion mixes, but preferably mix at 1: 1.
Its preparation process of defoamer of the present invention is as follows: stearic acid, polyoxyethyl propyl polyoxy ethyl glycerin ether and/or the polyoxyethyl propyl glycerin ether of specified quantity are placed container, and heating makes it liquidus temperature and surpasses 70 ℃ so that stearic acid is melted under stirring condition.Add the dimethicone of specified quantity after stearic acid all melts again, stirring and can obtaining outward appearance in 20～30 minutes is translucent liquid.
The present invention has following advantage compared to existing technology:
1. surface-active is big, surface tension is little, big to the contact angle of water, froth breaking power is strong, it is long to press down the bubble time.
Heatproof, anti-oxidant, not volatile, chemical stability is high, be difficult for and foaming medium generation chemical reaction.
3. nonhazardous can be widely used in food, medicine and other is industrial, selects different component and ratio according to the different scopes of application.
4. though consumption less but effect is better than other defoamer.
5. can increase tiring of product with this defoamer.
Example 1
Get 0.5 part of stearic acid and 99 parts of polyoxyethyl propyl polyoxy ethyl glycerin ethers, their addings are had in the reactor of steam jacket, start agitator and to chuck to feeding steam, make the interior temperature of container above 70 ℃, the dimethicone that adds 0.5 part after stearic acid all melts again in reactor, stirring and can obtaining outward appearance in 30 minutes is 100 parts of translucent defoamer liquid.
Example 2
Get the operation of 0.5 part of stearic acid, 99 parts of polyoxyethyl propyl glycerin ethers and 0.5 part of dimethicone repetition example 1, can obtain outward appearance is 100 parts of translucent defoamer liquid.
Example 3
Get the operation of 2 parts of stearic acid, 48 parts of polyoxyethyl propyl glycerin ethers, 48 parts of polyoxyethyl propyl polyoxy ethyl glycerin ethers and 2 parts of dimethicone repetition examples 1, can obtain outward appearance is 100 parts of translucent defoamer liquid.
Example 4
Get the operation of 2 parts of stearic acid, 60 parts of polyoxyethyl propyl polyoxy ethyl glycerin ethers, 37 parts of polyoxyethyl propyl glycerin ethers and 1 part of dimethicone repetition example 1, can obtain outward appearance is 100 parts of translucent defoamer liquid.
Example 5
Get the operation of 3 parts of stearic acid, 96 parts of polyoxyethyl propyl polyoxy ethyl glycerin ethers and 1 part of dimethicone repetition example 1, can obtain outward appearance is 100 parts of translucent defoamer liquid.
Example 6
Getting operation that 2 parts of stearic acid, 93 parts of polyoxyethyl propyl glycerin ethers and 5 parts of dimethicones repeat examples 1, can to obtain outward appearance be 100 parts of translucent defoamer liquid.
Annotate: the used percentage of the present invention all is weight percentage.
