Problems solved by technology

Although the preparation of silicon-acrylic emulsion by mini-emulsion polymerization has made up for the problem of instability of conventional emulsion polymerization to a large extent, there is still a certain degree of hydrolysis of the organosilicon monomer distributed on the interface between droplets and water, which makes the emulsion poor long-term stability

Abstract

The invention provides environment-friendly encaustic tile coating and preparation method thereof, belonging to the field of coatings for buildings. Organosilicon modified acrylic emulsion obtained by polymerizing miniemulsion is used as a film forming material, and iron series pigment is used as an auxiliary material to prepare the environment-friendly encaustic tile coating, wherein the organosilicon modified acrylic emulsion comprises the following components in percentage by weight: 10-30 percent of acrylate monomer, 1-5 percent of organosilicon monomer, 0.1-2 percent of complex emulsifying agent, 0.1-1.5 percent of sodium bicarbonate, 0.01-1.0 percent of initiator, 0.1-1.5 percent of emulsifying aid and 70-90 percent of deionized water. The water resistance, the weather resistance and the aging resistance of the encaustic tile coating prepared from the emulsion are obviously improved.

Description

technical field [0001] The invention belongs to the field of architectural coatings, and relates to an environment-friendly water-based color tile coating based on silicone acrylic emulsion and a preparation method thereof. technical background [0002] With the rapid development of my country's construction industry, people have put forward more requirements for architectural beautification. Colored cement roof tiles are a new type of wall and roof materials for beautifying buildings. Compared with traditional clay colored tiles, colored cement roof tiles have the advantages of high strength, light weight, rich colors, and good decorative effects on the one hand. On the other hand, in the production process of colored roof tiles, cement is used instead of clay, effectively Protect our country's precious land resources. [0003] The earliest cement color tile is to spray a layer of solvent-based paint on the surface of the cement. This solvent-based paint has a lot of VOC e...
