Method for preparing calcium stearate water based dispersion liquid

The invention discloses a method for preparing a calcium stearate water-based dispersion liquid. The method comprises the following steps: adding water and an emulsifier, dispersant, and 20-40% of the total content of a defoaming agent in a reaction kettle in a certain proportion, stirring until the emulsifier is dispersed uniformly, then stopping stirring, adding calcium stearate into the reaction kettle, then rapidly stirring until calcium stearate is completely wetted, then reducing the stirring speed and continuing to stir for 30-45 min, then adding a preservative and 60-80% of the total content of the defoaming agent into the reaction kettle, after carrying out superfine grinding for 3-8 min, screening through a 1000-1500 mesh supersonic wave vibrating screen, and obtaining the calcium stearate water-based dispersion liquid with the particle size of 5-10 microns. The method has the advantages of being simple in the formula, easy to operate, and short in time consumption; the product is non-crusting, is good inhomogeneity and stabilization, is environmentally friendly, has an adjustable solid content of calcium stearate and adjustable viscosity of the final system in a certain scope, and has an ideal lubrication effect—a kind of preparation method of calcium stearate aqueous liquid dispersion. The present invention relates to a kind of preparation method of calcium stearate aqueous liquid dispersion; this aqueous liquid dispersion is mainly a papermaking coating process auxiliary agent, plastic processing lubricant, waterproof textile agent, and paint flatting agent.
