Solid particle foam inhibitor and preparation method thereof

Abstract

The invention relates to a solid particle foam inhibitor and a preparation method thereof. The foam inhibitor component comprises an organic carrier, a main defoaming substance, an emulsifying agent, a structural agent and deionized water, wherein the organic carrier can be dextrin, starch, and the like; the main defoaming substance is a complex of high-viscosity silicone and low-viscosity silicone; and the structural agent can be acrylic acid and maleic acid copolymer, sodium citrate, and the like. The preparation method of the foam inhibitor comprises the following steps of: fully mixing the main defoaming substance with the emulsifying agent; then adsorbing the mixture on a carrier; adding the structural agent and granulating and drying to form a particle with favorable mobility. The prepared solid particle foam inhibitor is quite applicable to the industrial processes of cleaning, sewage treatment and textile printing and dyeing.

Description

technical field [0001] The invention relates to a solid particle antifoam agent and a preparation method thereof. The invention uses solid powder agglomerated polysiloxane to prepare a novel solid particle antifoam agent. This type of solid particle antifoam agent can be used in cleaning, daily chemical , sewage treatment, textile printing and dyeing and other industries. The solid particle foam suppressor belongs to fine chemical additives, therefore, the present invention belongs to the technical field of fine chemical preparations. technical background [0002] Foam is a common phenomenon in industrial processes such as industrial cleaning, sewage treatment, textile printing and dyeing, cement application, starch gelatinization, etc. Different systems have different reasons for foaming. For example, in industrial cleaning, industrial cleaning agents are used to remove dirt. Since the cleaning agent contains a large amount of surfactant, during the agitation process, the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the best-selling silicone defoamers on the market are mainly liquid types, which have the problems of poor compatibility and limited application range. In the cleaning industry, solid defoamers have unique advantages in comparison. Solid defoamers currently have the following problems: (1) Poor antifoaming performance; (2) Solid defoamers with zeolite as the carrier are prone to attenuation after long-term storage; (3) Sodium tripolyphosphate is used as the carrier (4) The solid defoamer with Yuanming powder as the carrier tends to become damp after being placed for a long time; (5) Some solid defoamers contain inorganic salts, and the content of inorganic salts Addition will affect other properties of the foaming system

The present invention mainly aims at the improvement of anti-foaming performance and the selection of suitable carrier, and develops a new type of solid particle anti-foaming agent, which not only solves the problems of easy moisture change and attenuation, but also is economical and environmentally friendly
