Abstract

The invention discloses a stable water-based calcium stearate dispersion and a preparation method thereof. The stable water-based calcium stearate dispersion comprises calcium stearate, an emulsifier,a deflocculating agent, a dispersing agent, a defoaming agent, a bactericide, polyoxyethylene ether, sodium sulfonate, sodium sulfate, urea, oleic acid, water and other components, and is obtained bymixing all above components through the three-step method. The stable water-based calcium stearate dispersion has the advantages of high solid content, low viscosity, good stability and environmentalfriendliness; and the preparation method of the stable water-based calcium stearate dispersion has the advantages of simple steps and economical cost.

Description

technical field [0001] The invention belongs to the field of chemical additives, in particular to a stable aqueous calcium stearate dispersion and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of coating technology, the demand for copper plate coated paper, high-gloss cast coated paper, glassine paper and carbonless copy paper in industrial production is increasing, and the requirements for coating quality are getting higher and higher. There are also more and more applications for dispersions. However, the existing calcium stearate emulsion has disadvantages such as poor stability, high dispersion viscosity, and low solid content, which is not conducive to the improvement of coating quality. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides a stable water-based calcium stearate dispersion with high solid content, low viscosity,...
