Abstract

The invention discloses an aqueous zinc stearate dispersion liquid. The aqueous zinc stearate dispersion liquid is prepared from the following components by weight: 35 to 45% of zinc stearate, 4 to 10% of an emulsifier, 1 to 4% of a dispersant, 0.1 to 0.5% of a defoaming agent, 0.1 to 0.3% of an antiseptic and 40.2 to 59.8% of water, wherein the content of the above-mentioned components sums to 100%. The invention further discloses a preparation method for the aqueous zinc stearate dispersion liquid. The aqueous zinc stearate dispersion liquid provided by the invention has the advantages of a small particle size, high solid content, small viscosity, good stability, no toxicity, environment friendliness and an ideal lubrication effect. The preparation method for the aqueous zinc stearate dispersion liquid is simple, easy to operate and beneficial for industrialized application and enables production cost to be reduced.

Description

technical field [0001] The invention relates to a zinc stearate water-based dispersion and a preparation method thereof. The zinc stearate water-based dispersion is mainly used as a rubber release agent, a papermaking coating lubricant, a sensitizer for heat-sensitive paper, and a water-based coating. Auxiliary. Background technique [0002] As a lubricant, zinc stearate is widely used in industries such as rubber, paper making, paint and cosmetics. Since zinc stearate is insoluble in water and is dispersed in the system in the form of particles, the particle size directly affects the dispersion effect of active ingredients. Usually, the particle size is large, difficult to disperse and easy to precipitate, and the use effect is not ideal, so it is generally made into an aqueous dispersion to give full play to its effect. [0003] At present, there are very few manufacturers producing zinc stearate water-based dispersions. Most of the products produced have large particle ...
