Abstract

The invention relates to the technical field of coatings, in particular to a water-resistant acrylate emulsion adhesive and a preparation method thereof. The preparation method of the water-resistant acrylate emulsion adhesive comprises the following steps: mixing polystyrene methyl methacrylate, methyl acrylate, hydroxyethyl acrylate, hydroxyethyl methylacrylate, hexyl acrylate, 2-ethylhexyl acrylate and methyl methacrylate, stirring and dissolving for 60-80 minutes at the temperature of 45-50 DEG C; adding a defoaming agent, a thickening agent and a surfactant for continuous reaction, wherein the reaction temperature is 50-55 DEG C, and the reaction time is 25-35 minutes; and adding an emulsifying agent and deionized water for emulsifying at the emulsifying temperature of 55-60 DEG C for 25-35 minutes, and stopping heating to obtain the water-resistant acrylate emulsion adhesive. According to the preparation method, the reaction temperature and the reaction time in the preparation process can be effectively reduced, so that the energy consumption is effectively reduced, the production efficiency is improved, and the problems of high energy consumption and low production efficiency in the preparation process of the existing adhesive are solved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-resistant acrylate emulsion adhesive and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of urbanization and the improvement of people's living standards, the standards for architectural coatings have also been continuously improved. Decorative materials represented by ceramics, artificial stones and natural stones have been greatly welcomed, but the biggest disadvantages Therefore, after these substrates are bonded to concrete, hollowing and shedding appear in a short period of time. The main reason for this phenomenon is that the performance of early tile adhesives is unstable and the reaction with concrete is poor. Therefore, acrylate emulsion adhesives entered the market in due course. [0003] Although the acrylate emulsion adhesive can effectively solve the hollowing and shedding phenomenon during tile laying...
