Abstract

The invention relates to a polyether amine derivative modified styrene-acrylic emulsion and a preparation method thereof. Weight part, the polyether amine derivative modified styrene-acrylic emulsioncomprises the following components in parts by weight: 5.0-12.0 parts of a polyether amine derivative, 12.0-30.0 parts of an acrylate hard monomer, 4.0-15.0 parts of an acrylate soft monomer, 4.0-8.0parts of glycidyl acrylate, 15.0-30.0 parts of styrene, 1.5-4.0 parts of a cross-linking monomer, 2.0-4.0 parts of acrylic acid. 0.1 to 0.4 part of benzoyl peroxide, 0.4 to 0.8 part of sodium bicarbonate, 2.5 to 8.0 parts of a neutralizer, 1.5 to 5.0 parts of an emulsifier, 5.0 to 10.0 parts of a cosolvent, and 100.0 to 200.0 parts of deionized water; wherein the mass ratio of the acrylic acid hard monomer to the acrylic acid soft monomer is 2.0-3.0: 1; the polyether amine derivative modified styrene-acrylic emulsion prepared by the invention has the characteristics of good adhesive force, good flexibility, high hardness and the like, contains a Schiff base structure and has good sterilization and antibacterial functions, and when a coating is prepared, a bactericide does not need to be added additionally.

Description

technical field [0001] The invention relates to a modified styrene-acrylic emulsion, in particular to a polyetheramine derivative modified styrene-acrylic emulsion and a preparation method thereof, belonging to the technical field of synthetic resins. Background technique [0002] The emulsion obtained by copolymerizing monomers such as styrene and acrylate is called styrene-acrylate emulsion, or styrene-acrylic emulsion for short. 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. Because of its high cost performance, non-toxic, odorless, non-combustible, less pollution, weather resistance, stain resistance, corrosion resistance and other characteristics, it is widely used in adhesives, paper sizing agents and coatings. [0003] However, due to the poor performance of the traditional styrene-acrylic emulsion coating fil...
