Abstract

The invention discloses a graphene oxide modified organic silicon defoamer, which comprises the following raw materials in percentage: graphene oxide modified organic silicone oil 5-12%, dimethyl silicone oil 10-25%, silica 2-5%, polyether 7-10%, emulsifier 5-7%, catalyst 0.05-0.15%, stabilizer 1-4%, deionized water 50-60%, fixed high viscosity silica paste 3-5%, low viscosity silica paste 2-6% and white carbon black 3-10%. The invention has the advantages of simple production process, easily available raw materials, no pollution, easy industrial production, short defoaming time, high efficiency, high temperature resistance, acid and alkali resistance, hydrophilicity and the like, and moderate price, and can be widely applied to printing and dyeing, ink, coating, papermaking and other industries.

Description

technical field [0001] The invention relates to the technical field of defoamers, in particular to a graphene oxide modified silicone defoamer and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, industries involving stirring will be accompanied by the generation of foam, such as papermaking, ink, paint, fermentation, printing and dyeing and other industries. Foam is a coarse dispersed phase of gas in liquid. On the one hand, it will greatly limit industrial production capacity; on the other hand, it will cause waste of raw materials and products, and affect the quality and performance of products. The industry usually chooses to add a defoamer to the reaction system to eliminate and suppress the generation of foam. However, the defoaming efficiency of the existing defoaming agent is not high, the defoaming time is long, and it is not resistant to high temperature and acid and alkali, which is not conducive to...
