Abstract

The invention discloses zinc stearate sol low in free acid content and a preparation method thereof. The zinc stearate sol is prepared by reaction under model temperature of krfft*2 DEG C. The zinc stearate sol comprises, by weight percentage, 86.7% of stearic acid emulsion and 13.3% of zinc oxide dispersion liquid, wherein the zinc oxide dispersion liquid comprises, by weight percentage, 4% of zinc oxide, 1% of dispersing agent, 0.1% of multifunctional catalyst, 0.1% of defoaming agent, 0.1% of environment-friendly sterilizing agent and 8% of deionized water. The preparation method has the advantages that the reaction is complete, the generation of three wastes is avoided, reaction byproducts are avoided, the prepared zinc stearate sol is low in free fatty acid content, pure in component and small in particle size, and the low viscosity of high-solid-content products is guaranteed; independent catalyst pollution is avoided, and low fatty acid residues are achieved; the conversion rate and fineness of zinc stearate are increased; the method is high in yield, minimum in energy consumption and simplified in process control, and the prepared zinc stearate sol is low in particle size distribution.

Description

technical field [0001] The invention relates to the technical field of camellia oleifera, in particular to a zinc stearate sol with low free acid content and a preparation method. Background technique [0002] Zinc stearate is a widely used fine chemical material, but its application is limited due to its strong hydrophobicity. Zinc stearate sol is a water-soluble product that expands applications and improves use efficiency, and is widely used in rubber, plastics, coatings, inks, paints, thermal paper, cosmetics and other industries. At present, my country's coatings, papermaking, and cosmetics industries, which consume a large amount and have high quality requirements, almost use imported products from Japan and Germany. The prices are relatively high, and there is no room for negotiation on prices. The reason is that imported products have low free acid content, good dispersibility, small particle size, high effective content, pure ingredients, and stable and reliable qu...
