Another kind is the two-step method, and preparation calcium stearate powder is distributed to the calcium stearate powder under the effect of auxiliary agents such as surfactant in the water more uniformly earlier, grinds at last. This method is simply easy and is the maximum method of the synthetic employing of calcium stearate in the market; But, because calcium stearate has stronger hydrophobicity, the shortcoming is that the emulsifying dispersant consumption is big, and the relative cost is higher when therefore preparing. Therefore, guaranteeing that every index of calcium stearate aqueous liquid dispersion reaches the required requirements under the prerequisite of the production application, reasonably optimizing prescription, and reducing cost is very important. To address the above problem, this invention aims to provide a kind of preparation method for calcium stearate aqueous liquid dispersion, simple, the consuming time weak point of its production technology, reduced production cost, the performance of calcium stearate aqueous liquid dispersion is improved significantly. The calcium stearate aqueous liquid dispersion method for preparing gained solid content is 30～55wt%, the particle size range is 5～10 μ m, and the range of viscosities is 106～234mPa.S.
Further, as mentioned above, the dispersant is one or more combinations in styrene-maleic anhydride copolymer, stearyl polyethylene ether, sodium phosphate trimer, sodium pyrophosphate, PEG400, and urea. Further, the above-mentioned emulsifying agent is one or more combinations in Tween-80, polysorbate60, sodium sulfate of polyethylene ether of fatty alcohol, polyoxyethylene-polyoxypropylene copolymer, fatty alcohol-polyoxyethylene ether, polyglycerol monolaurate, the polyethylene glycol laurate.
