Abstract

The invention discloses a special anti-foaming agent for resin. The special anti-foaming agent is prepared from, by weight, 15-25% of modified dimethicone, 10-15% of modified polymethylacrylic acid glyceride, 3-18% of paraffin, 4-15% of vegetable oil, 5-10% of glycerin, 3-10% of ethyl alcohol, 3-15% of aluminum stearate, 2-8% of an emulsifying agent, 1-8% of a dispersing agent and 0.1-0.3% of catalysts. The materials are added and stirred for 30-50min to obtain the special anti-foaming agent for resin. The molecular weight of polydimethyl siloxane fluid is 10000-30000, and density of the vegetable oil is 0.837-0.934g / cm<3> below 20 DEG C. The special anti-foaming agent has advantages of high anti-foaming performance, long foam inhibition time, stability in performance, environmental friendliness, nontoxicity, harmlessness, low addition quantity, low cost, easiness in storage and transport and the like.

Description

technical field [0001] The invention relates to the field of defoamer production, in particular to a special defoamer for resin production. Background technique [0002] At present, there are many types of defoamers in industry, and their performances are uneven and not perfect, especially in the industrial resin production industry. Therefore, there is an urgent need in this field for a defoamer with fast defoaming speed, simple preparation, low cost and convenient transportation. agent. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the object of the present invention is to provide a special defoamer for resin, which aims to solve the problems of slow defoaming speed and high cost of industrial defoamers in the prior art. [0005] A special defoamer for resin, wherein: by weight percentage, comprising: [0006] Modified simethicone 15-25%; [0007] Modi...
