Description
Technical Field
The invention belongs to the technical field of defoaming agents, and particularly relates to a defoaming agent for coating ink.
Background
In the fields of oil and gas exploitation, pulping and papermaking, textile printing and dyeing, biological fermentation, sewage treatment, coating processing, building industry and the like, the foam generated by stirring can cause the problems of capacity reduction, reaction period extension, raw material waste and the like. The addition of the defoaming agent can eliminate the foam in a short time. The defoaming agent can be divided into mineral oil defoaming agent, polyether defoaming agent, organic silicon defoaming agent and the like. The mineral oil defoaming agent can only be used under the conditions of small liquid shearing force and mild foaming capacity of the contained surfactant, and has poor capability of eliminating compact foam.
The polyether defoamer can only play a defoaming role when the temperature of a foaming system exceeds a cloud point temperature. In recent years, silicone defoaming agents have attracted much attention because of their high defoaming efficiency, small amount and no physiological toxicity, but silicone has poor dispersibility, is difficult to emulsify, tends to aggregate into oil droplets having an excessively large particle size and no defoaming activity, and pure silicone oil has no defoaming effect on foams in aqueous solutions.

Preferably, the defoaming agent for the coating ink is prepared into an aqueous solution with the mass fraction of 0.1-1.0% for use.
The invention has the beneficial effects that:
1. the defoaming agent for the coating ink ensures the overall defoaming and foam inhibiting effects of the defoaming agent, the added auxiliary agent component can effectively promote the effects of the main active components to be exerted, and simultaneously can improve the conditions of invalidation such as viscosity increase, crosslinking tendency and the like caused by the overall long-term storage, and improve the stability of the quality during storage and use. Finally, under the combined action of the components, the defoaming agent for the coating ink, which is prepared by the invention, has good defoaming and foam inhibiting properties, stable quality after long-term storage and use and good use value.
2. The defoaming agent for the coating ink is added with substances such as hydrophobic silicon dioxide, nano silver oxide, nano zinc oxide and the like, and the substances are mutually matched and can be used as a defoaming core to play a role in quickly defoaming.
