Abstract
The present invention discloses a kind of modified organic silicon defoamer and preparation method thereof, and by weight percentage, modified organic silicon defoamer includes：Dimethicone 60 80%；White carbon 5 25%；Tween 1 5%；Poly- methyl polyoxyethylene ether 1 3%；AEO 1 4%；Sodium carboxymethylcellulose 5 25%；Sorbic acid 0.1 2%；Catalyst 0.1 0.3%.It is rapid that the present invention dissolves CMC in emulsion-type organic silicon defoamer preparation technology, dissolution time significantly shortens, and need not individually pre-dispersed dose, the stability of product can further be improved on original Process ba- sis using the method simultaneously, therefore the method greatlys save time, energy consumption and the cost of whole preparation technology, and improves product quality.
Description
Technical field
The present invention relates to defoamer production field, more particularly to a kind of modified organic silicon defoamer and its preparation side
Method.
Background technology
In order to ensure the quality of emulsion-type organic silicon defoamer, emulsify preparation technology in often need by using chemistry,
Machinery or other methods strengthen its stability.It is mainly by adding sodium carboxymethylcellulose in chemical method at present
（Abbreviation CMC）Realized with increasing the viscosity of system, but solubility of the CMC in water is not high, and course of dissolution is also quite very long,
Directly CMC is added to the water, occurs that a large amount of clear gum things are suspended in reactor surface after stirring, formed " flake ",
Constantly adhere to on wall and agitator simultaneously, cause feedstock portions to waste, even if the CMC in water also usually needs stirring
Could substantially completely dissolve within 4-6 hours.On the other hand the polysaccharide structures that it has, when temperature is raised, its solubility drops on the contrary
It is low, and emulsion-type organic silicon defoamer often needs to be carried out at a temperature of 60-75 DEG C in preparation process, thus more increases it
The degree of difficulty of water is dissolved in actual production, so as to cause course of dissolution slow, wastage of material further, the froth breaking is ultimately resulted in
The quality of agent is affected.
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 modified organic silicon defoamer and its system
Preparation Method, it is intended to the problems such as solving the poor solubility property that organic silicon defoamer is present in the prior art, product stability difference.

A kind of preparation method of modified organic silicon defoamer as described above, wherein：Sequentially added in 55-80 DEG C of water
Dimethicone, white carbon, tween, poly- methyl polyoxyethylene ether, AEO, sodium carboxymethylcellulose, sorb
Acid, catalyst, are stirred mixing, are finally cooled to normal temperature.
The present invention dissolves CMC rapidly in emulsion-type organic silicon defoamer preparation technology, and dissolution time is by original 4-6
Hour is reduced to 1-1.5 hour, and need not individually pre-dispersed dose, while can be in original Process ba- sis using the method
The upper stability for further improving product, therefore the method greatlys save time, energy consumption and the cost of whole preparation technology, and
And improve product quality.
