Abstract

The invention discloses an antibacterial styrene-acrylic emulsion, and a preparation method and the application thereof. The emulsion is prepared from the following components in parts by weight: 40 to 60 parts of deionized water, 15 to 20 parts of styrene, 15 to 20 parts of butyl acrylate, 3 to 5 parts of an emulsifier, 1 to 2 parts of a water-soluble initiator, 0.5 to 1 part of an oxidation-reduction system initiator, 2 to 7 parts of an antibacterial monomer, 0.1 to 0.3 part of a pH value regulator and 3 to 5 parts of other auxiliaries. By taking a main measure of adding a monomer having the antibacterial function for participation in polymerization reaction during synthesis of the styrene-acrylic emulsion, the styrene-acrylic emulsion has an antibacterial function, and no antibacterial auxiliary is needed; moreover, the styrene-acrylic emulsion is uniform in dispersion and difficult to seep. The antibacterial styrene-acrylic emulsion has the characteristics that the styrene-acrylic emulsion is high in efficiency and low in toxicity, is hardly affected by the change of the pH value, and is convenient to use, has a relatively strong stripping function for a mucous layer, is stable in chemical property, and has relatively good dispersion and corrosion inhibition effects.

Description

technical field

[0001] The invention relates to a building decoration material, in particular to an antibacterial styrene-acrylic emulsion, a preparation method and application. Background technique

[0002] Styrene-acrylic emulsion (styrene-acrylate emulsion) is mainly obtained by emulsion copolymerization of styrene and acrylate monomers. It is 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. Because styrene-acrylic emulsion has good adhesion, transparent film, good water resistance, oil resistance, heat resistance and aging resistance, it is widely used in interior and exterior wall coatings. In order to improve the comprehensive performance of styrene-acrylic emulsion coatings fo...
