Abstract

The invention discloses an organic silicon de-foaming agent and a preparation method of the organic silicon de-foaming agent. The organic silicon de-foaming agent is prepared from the following formula components in parts by mass: 10 to 20 parts of fluorite, 5 to 7 parts of tert-amyl chloride, 3 to 5 parts of thulium trifluoroacetylacetonate, 3 to 5 parts of sodium carbonate, 3 to 5 parts of benzyltriphenylphosphonium bromide, 2 to 4 parts of 3-methyl-2-buten-1-ol, 4 to 6 parts of hydrophobic silicon dioxide, 6 to 8 parts of dimethicone, 10 to 12 parts of tetrabutylphosphonium bromide, 10 to 20 parts of coke, 5 to 15 parts of mineral oil, 10 to 12 parts of albite and 40 to 60 parts of water. The organic silicon de-foaming agent provided by the invention is simple in process, convenient to use and high in production efficiency and the utilization effect of the obtained de-foaming agent is good.

Description

technical field [0001] The invention relates to the technical field of defoaming, in particular to a silicone defoaming agent and a preparation method thereof. Background technique [0002] In most industrial production processes, a large number of air bubbles will affect production efficiency, product quality or cause equipment damage. Therefore, defoamers are widely used in various fields such as textiles, papermaking, petroleum, food, sewage treatment, pharmaceuticals, etc. In the papermaking industry, Foam will lead to abnormal production and paper defects, or even paper breaks, which will greatly reduce the working efficiency of the paper machine and the quality of paper output, and delay labor time and cause losses. The use of defoamers is one of the effective means of eliminating harmful foam in industry. Silicone defoamer has the characteristics of low mechanical tension, good chemical stability, heat resistance, and less dosage, and can adapt to the defoaming of we...
