Water based calcium stearate dispersion for papermaking and preparation method thereof
The invention relates to a water-based dispersion and a preparation method, wherein the water-based dispersion takes calcium stearate as the main component and is used for papermaking. The dispersion is mainly used as an auxiliary, a functional auxiliary, and a coating lubricant in the papermaking and coating processes. The dispersion is formed by processing the calcium stearate, an emulsifier A, an emulsifier B, an auxiliary, a dispersing agent, a defoamer, a fungicide, and water; and the product comprising the steps of adding the calcium stearate, the emulsifier, A, the emulsifier B, the auxiliary, the dispersing agent, the defoamer, the fungicide, and the water into a high-pressure reaction kettle according to a certain proportion; sealing the high-pressure reaction kettle and heating to 160-190DEG C; mixing the materials at a constant temperature for one h; and then rapidly cooling to the room temperature to obtain the target product. According to the proportion and the method, the viscosity range of the prepared water-based calcium stearate dispersion is 90-680mPa.S, the particle size range is 0.45-5.0 microns, and the solid content is 39-75wt%. The water-based calcium stearate dispersion has the advantages of a simple process, high efficiency, no color reversion of the product, no odor, no pollution, and the like; and the particle size, the solid content, and the viscosity are adjustable. Water-based calcium stearate dispersion liquid of a kind of paper grade (stock) and preparation method thereof The present invention relates to a kind of main paper grade (stock) water-based dispersion liquid of forming and preparation method thereof with the calcium stearate, and this dispersion liquid is mainly as paper making and cloth coating process auxiliary agent, functional aid and coating lubricant.
