Real stone paint is based on one or more synthetic resin emulsions, adding a small amount of film-forming aids as bonding materials, using different grades of natural colored sand or artificial sand as aggregates, and adding dispersants and defoamers in a quantitative manner. , bactericide, multifunctional additives, thickeners and a series of additives, adding quantitative deionized water to prepare a high-quality, high-performance architectural coating with a decorative effect similar to marble, granite and other stone materials. The film structure of real stone paint is as follows:
Based on the problems of current engineering applications such as low bonding strength of real stone paint, whitening when exposed to water, blooming, cracking and falling off, and poor stain resistance, Cha Ling's article "Research on the Preparation and Performance of Real Stone Paint" mainly studies the middle layer of real stone paint. Starting with the composition, mechanism of action, preparation method, and the choice of finish paint, through a large number of experimental comparisons and orthogonal methods, a real stone paint exterior wall coating system with better effect is obtained, and the experimental results are analyzed. Types and dosages of emulsions, types and dosages of aggregates, dosages of film-forming aids, types and dosages of dispersants, types and dosages of thickeners, types and dosages of defoamers, types and dosages of silicone additives, etc. The influence of real stone paint performance.
Summarize
Through the analysis of the experimental results, the final conclusions are as follows:
