Abstract

The invention relates to the technical field of paste production methods, and specifically relates to a production method of spray water paste. The method comprises the following steps: (1) first mixing: sequentially adding 2-4 parts of an acrylic acid, 3-5 parts of butyl acrylate, 4-6 parts of methyl methacrylate and 1-3 parts of a methacrylic acid into a polymerization kettle to stir in part by weight, and heating the obtained mixture to 80 DEG C; (2) second mixing: dropwise adding 1-3 parts of water, 2-4 parts of an emulsifier and 2-4 parts of an initiator into the polymerization kettle in the step (1) to stir in part by weight, and after the dropwise adding is completed, carrying out heat preservation on the obtained product 4 hours, wherein the dropwise adding temperature is 80-85 DEG C, and the dropwise adding time is 5-6 hours. According to the invention, through adopting the steps of mixing, polymerization and cooling and the like, the prepared spray water paste has the characteristics of low viscosity, good heat dissipation, good heat shrinkable property, less impurities, uneasiness for blistering, and uneasy production of cracks on paste membranes, and the like, and the concentration of odor emitted by the prepared spray water paste is low. In addition, the method disclosed by the invention is simple in production method, low in cost, and small in environmental pollution.

Description

technical field [0001] The invention relates to the technical field of slurry production methods, in particular to a production method of water spray slurry.
