Abstract

The invention discloses a high-efficiency rubber antifoaming composition, which is composed of the following raw materials (by weight): 50-60 parts of siloxane, 3.6-7.5 parts of triacetin, 1.6-2.5 parts of ethylene bis stearamide, 23-35 parts of hydrophobic silica, 2.6-3.2 parts of methylcyclohexane, 1.4-2.2 parts of magnesium stearate, 1.2-2.3 parts of Di-n-octyltin oxide, 10-15 parts of high carbon alcohol, 2.4-3.4 parts of ethyl acrylate, 3.5-6.5 parts of benzyltriphenylphosphonium bromide, 5-9 parts of an aluminate coupling agent, 10-20 parts of cement clinker, 8-12 parts of polyvinyl acetal resin, 20-30 parts of water glass, 2.7-3.2 parts of t-pentane chloride, and 3-7 parts of multivalent metal salt. The rubber antifoaming composition of the invention has the advantages of low cost,great improvement of calcium oxide storage time, good stability, difficulty in moisture absorption and deterioration, easy weighing, high moisture absorption efficiency, stable product quality and thelike.

Description

technical field [0001] The invention relates to the technical field related to rubber, in particular to a high-efficiency rubber defoamer composition. Background technique [0002] Antifoaming agent, also known as antifoaming agent, is a food additive that reduces surface tension during food processing, inhibits foam generation or eliminates foam that has already occurred. There are many types of existing defoamers, some will affect the basic properties of the foaming system, some have poor defoaming effect, poor suppression performance, some are not good enough in diffusivity, and some are chemically unstable and safe The performance is not high. Contents of the invention [0003] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, and propose a kind of high-efficiency rubber defoamer composition. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A ...
