Abstract

The invention provides a styrene-acrylic emulsion for manufacturing artificial stone for solving the problems of lots of harmful VOCs (volatile organic compounds) existing in artificial stone, as well as high shrinkage percentage, low flame retardance, bad corrosion resistance, low hardness and the like of products, and provides a preparation method for the emulsion, and artificial stone prepared from the emulsion. The artificial stone is excellent in chemical corrosion resistance, pollution resistance, heat resistance and water resistance, and great in hardness.

Description

technical field [0001] The invention relates to a styrene acrylate emulsion used for manufacturing artificial stones, a preparation method thereof and the prepared water-based artificial stone, belonging to the fields of polymer chemistry and new materials. Background technique [0002] Artificial stone is a new product that first appeared in the United States in the 1930s. There are many ways to manufacture artificial stone, and the main raw materials are adhesives and fillers. Adhesive is the most important factor to determine the quality of artificial stone. From the perspective of adhesives, artificial boulders can be divided into two categories: inorganic artificial stones and organic polymer artificial stones. [0003] Among them, organic artificial stone has been sought after by people because of its superior performance. The current artificial stone research work is progressing rapidly. Some problems it faces, such as the aging problem of organic polymer artifici...
