Abstract

The invention relates to the technical field of emulsion coatings, specifically to a styrene-acrylic emulsion. The styrene-acrylic emulsion comprises the following components in parts by weight: 85 to105 parts of acrylate monomer, 55 to 75 parts of styrene monomer, 1 to 5 parts of butyl acrylate, 4 to 10 parts of a weather-proof material, 1 to 8 parts of sodium bicarbonate, 1 to 4 parts of a silane coupling agent, 2 to 3 parts of an emulsifier, 1 to 3 parts of an initiator and 150 to 300 parts of deionized water. A water-resistant material is prepared from the following components in parts byweight: 15 to 30 parts of sodium fatty alcohol polyethylene sulfonate, 10 to 20 parts of silicon dioxide powder, 5 to 15 parts of silicone amide, 2 to 10 parts of hexamethylenediamine and 2 to 5 parts of triethylene tetramine. The styrene-acrylic emulsion prepared according to a formula disclosed by the invention has good weather resistance, and is applied to the coating industry so as to allow acoating to also have good weather resistance.

Description

technical field [0001] The invention relates to the technical field of emulsion coatings, in particular to a styrene-acrylic emulsion. Background technique [0002] Styrene-acrylic emulsion (styrene-acrylate emulsion) is obtained by emulsion copolymerization of styrene and acrylate monomers. Styrene-acrylic emulsion is the most researched system in emulsion polymerization, and it is also one of the top ten non-crosslinked emulsions with important industrial application value in the world today. As an important class of intermediate chemical products, styrene-acrylic emulsion has a very wide range of uses. It is mainly used as architectural coatings, metal surface latex coatings, floor coatings, paper adhesives, adhesives, etc. [0003] The formula of the existing styrene-acrylic emulsion mainly includes four parts of styrene monomer, acrylate monomer, emulsifier and initiator. Although the styrene-acrylic emulsion prepared by this formula has good oil resistance, heat resis...
