example 1

[0022] Mix stearic acid and sodium hydroxide in a beaker at a mass ratio of 10:1, add water 5 times the mass of stearic acid into the beaker, and stir the reaction at a temperature of 85°C and a rotational speed of 400r / min. After 80 minutes, dilute sodium soap solution was obtained; the vermiculite was ground through a 100-mesh sieve to obtain fine vermiculite; the fine vermiculite and water were mixed in a flask at a mass ratio of 1:40, and fine vermiculite was added to the flask Alkyl quaternary ammonium salt with 4 times the mass of stone, under the conditions of temperature 85°C and rotation speed 350r / min, stirred and reacted for 9h, filtered to obtain filter cake, after the filter cake was washed 12 times with deionized water, in Dry to constant weight at a temperature of 90°C to obtain pretreated vermiculite; mix pretreated vermiculite with water at a mass ratio of 1:120, and add the mass of pretreated vermiculite to the mixture of pretreated vermiculite and water 2 ti...

Abstract

The invention discloses a preparation method of a waterborne zinc stearate dispersion solution and belongs to the technical field of chemical auxiliary agents. The preparation method comprises the following steps: mixing modified vermiculite sol and a diluted soda soap solution according to the mass ratio ranging from (10 to 2) to (10 to 3) in a reaction kettle; stirring and reacting for 30 to 60min under the conditions that the temprature is 80 to 85 DEG C and the rotary speed is 300 to 350r / min; then adding stearic acid which is 0.3 to 0.5 time of the mass of the modified vermiculite sol, ade-foaming agent which is 0.05 to 0.08 time of the mass of the modified vermiculite sol and a fungicide which is 0.01 to 0.05 time of the mass of the modified vermiculite sol; stirring and reacting for 2 to 4h under the conditions that the temprature is 80 to 88 DEG C and the rotary speed is 300 to 380r / min, so as to obtain the waterborne zinc stearate dispersion solution. The waterborne zinc stearate dispersion solution obtained by the invention has excellent dispersity.

Description

technical field [0001] The invention discloses a preparation method of a water-based zinc stearate dispersion liquid, belonging to the technical field of chemical additives. Background technique [0002] Higher fatty acid salts of metals other than sodium and potassium are commonly called metal soaps. They have the dual characteristics of metal salts and fatty acids, and are widely used as plastic stabilizers, lubricants, halogen absorbers, grease thickeners, textile waterproofing agents, Paint flatting agent and cosmetic powder and tablet release agent, etc. [0003] Stearate is a white, greasy, light, fine powder substance, insoluble in water, high melting point, good high-temperature film-forming performance, and the film is transparent or translucent. Stearate is widely used. For example, stearate can be used as PVC heat stabilizer, softener, lubricant, and film-forming agent; stearate is used as a good light stabilizer on agricultural films, which can inhibit the impac...
