MANUFACTURING METHOD OF HIGHLY WATER-RESISTANT EMULSION FOR CONCRETE COATINGS WITH WATER-REDUCTION AND SURFACE-PENETRATION FUNCTIONS

摘要

The present invention relates to an emulsion resin composition for highly water-resistant concrete surface coatings having a permeability and a water sensitizer, and a method of manufacturing the same, and an object thereof is a methylmethacrylate / acrylic acid water-soluble resin having a water soluble function to perform a steric hindrance as a emulsifier. And emulsion resin compositions for highly water-resistant concrete surface coatings having a permeability and a water repellent function to impart electrostatic stability and to prevent coagulation by calcium ions so as to polymerize resin-reinforced emulsions having excellent compatibility with cement. It is to provide a manufacturing method.;The present invention comprises the steps of dissolving methyl methacrylate / acrylic acid water-soluble resin in water having a pH of 9 or more; Putting methyl methacrylate / acrylic acid water-soluble resin dissolved in water having a pH of 9 or more into the reactor at a time; Heating the reaction temperature of the reactor to 80 ° C; Initiating a reaction by adding ammonium persulfate to the reactor; Methyl acrylate, butyl acrylate, 2-ethyl hexyl acrylate is added to the reactor in a semi-continuous manner to prepare an emulsion resin composition for a highly water-resistant concrete surface coating agent having a permeability and a water reducing agent through the step of emulsion polymerization. have.;Emulsion resin, high water resistance, methyl methacrylate / acrylic acid water soluble resin, water reducing agent, emulsifier
