Acrylic emulsion for encaustic tile paint

Abstract

The invention discloses an acrylic emulsion for encaustic tile paint, which is mainly prepared from alkene monomers, an emulsifier, a co-emulsifier, an initiator, a buffering agent and water. The improvement of the invention is as follows: alkene hydrophobic function monomer acrylamide and alkene organosilane coupling agent are utilized to modify acrylic polymers, thereby enhancing the adhesion of the polymers to cement tiles and the rainfall erosion resistance of the polymers; and especially, polyester polyol with proper molecular weight is introduced into the emulsion polymerization to obviously enhance the luster, fullness and leveling property of the polymer film, thereby enhancing the color vividness and brightness of encaustic tiles. The emulsion is mainly used for manufacturing roof encaustic tile paint, thereby beautifying the roofs of the city buildings.

Description

technical field [0001] The invention relates to an acrylic emulsion for color tile paint. Background technique [0002] Color tile is a kind of cement tile that has developed rapidly in recent years with the acceleration of urban construction, and has replaced the original earth-fired tile. Color tile paint is a paint emulsion used to decorate and protect cement tiles. At present, due to the influence of emulsifier and water, the domestic acrylic emulsion has a large gap with solvent-based paint in terms of gloss, fullness, leveling, water resistance, etc. In the prior art, the method of changing the particle size of emulsion particles is generally used to narrow the gap in glossiness. It has been reported in the literature that in order to obtain a higher gloss coating, the particle size of the emulsion is required to be as small as possible, because the emulsion with a fine particle size has excellent film-forming properties and adhesion properties to pigments, thereby i...

Problems solved by technology

However, the smaller the particle size of the emulsion, the greater the viscosity, which will lead to poor leveling and fullness, and then affect the gloss. The relationship between these is difficult to grasp. Other properties of the coating can only be improved through functional monomer modification. It is difficult to improve the gloss, leveling and fullness of the coating, so no matter through various technical modifications, including core-shell, interpenetrating network and other methods, it is difficult to achieve the ideal coating effect for the coating used for color tiles
