Description

A kind of special defoamer of resin

Technical field

The present invention relates to defoamer production field, more particularly to the special defoamer of production of resins.

Background technology

Industrial defoamer species is various at present, and performance joins that its is uneven, not perfect enough, is especially produced in resin of industry and gone Industry, therefore, this area is fast in the urgent need to a kind of antifoaming speed, prepares simple, low cost, the defoamer of convenient transportation.

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 special defoamer of resin, it is intended to solve Certainly prior art industrial defoaming agent antifoaming speed is slow, high cost the problems such as.

A kind of special defoamer of resin, wherein：By weight percentage, including：

Modified dimethicone 15-25%;

Modified polymethyl acid glyceride 10-15%;

Paraffin 3-18%;

Vegetable oil 4-15%;

Glycerine 5-10%;

Ethanol 3-10%;

Aluminum stearate 3-15%;

Emulsifying agent 2-8%;

Dispersant 1-8%;

Catalyst 0.1-0.3%.

The special defoamer of described resin, wherein：, in 10000-30000, vegetable oil is 20 for polydimethyl siloxane fluid molecular weight Density at DEG C is in 0.837-0.934g/cm3.

Defoamer of the invention has defoaming capacity strong, and the suds time is long, and the tender stabilization of property, environment-protecting asepsis are harmless, addition It is few, low cost, it is easy to the features such as being stored in transport.

Specific embodiment

The present invention provides a kind of special defoamer of resin, for make the purpose of the present invention, technical scheme and effect it is clearer, Clearly, the present invention is described in more detail below.It should be appreciated that specific embodiment described herein is only used to explain this Invention, is not intended to limit the present invention.
