Description
Technical field
The present invention relates to chemical industry preparation technique field, more particularly to a kind of high efficiency defoamer and preparation method thereof.
Background technology
Foam may be defined as the gas being stabilized in liquid medium.In latex, textile sizing, food fermentation, biology doctor
Many unwanted bubbles can be produced in the commercial process of the industries such as medicine, agricultural chemicals, coating, petrochemical industry, papermaking, and then are influenceed
Plant capacity, the waste of raw material is caused, extend reaction time, influence product quality etc., therefore often need to add defoaming
Purpose caused by bubble is reduced or avoided to reach in agent.
Defoamer can be divided into two kinds of approach of suds and brokenly bubble from intreractive theory, and suds refer to suppress bubble as its name suggests
The generation of foam, that is to say, that favorable factor caused by foam is eliminated from source, and brokenly bubble refers to abolish caused foam,
To have the function that to reduce foam.Two kinds of defoaming modes of defoamer can all play a part of effectively controlling bubble amt, therefore
Important function is respectively provided with actual production.

S1, the dimethicone and polyvinylether for weighing corresponding parts by weight, after being well mixed, mixed liquor A is obtained, by corresponding parts by weight
Organosiloxane be encased in dropping funel, and side is stirred liquid A with 500~1000r/min speed, while by dropping liquid
Organosiloxane in funnel is added drop-wise in mixed liquor A, and the time for adding of organosiloxane is 10~20min/L, is treated organic
Siloxanes continues 5~10min of stirring after being added dropwise, obtain mixture B；
S2, mixing speed is down to 200~300r/min, then the double hard esters of hexenyl of corresponding parts by weight are added into mixture B
Acid amides, glyceryl monostearate and surfactant, continue 5~10min of mixing, mixing speed is then risen into 400~800r/
Min, montmorillonite powder, molybdenum disulfide, charcoal powder and the inorganic salts of corresponding parts by weight are added, continue 10~20min of stirring, are obtained mixed
Compound C, then 4A molecular sieves are added into mixture C, continue 5~10min of stirring, add the metal oxidation of corresponding parts by weight
Thing, produce high effective antifoaming agent.
