Waterborne acrylic resins include acrylic resin emulsions, aqueous acrylic dispersions (also known as water-reducible acrylics), and aqueous acrylic resins
Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, resource and energy saving, and reduction of environmental pollution and pollution. Therefore, they have become the main direction for the development of the paint industry. Water-based acrylic olefin resin coatings are the most rapidly developing and most non-polluting coatings in waterborne coatings.
Waterborne acrylic resins include acrylic resin emulsions, acrylic resin water dispersions (also known as water-reducible acrylics), and aqueous acrylic resins. Emulsions are mainly synthesized by emulsifying oily vinyl monomers in water under the action of an aqueous free radical initiator, while aqueous resin dispersions are synthesized by different processes such as radical solution polymerization or stepwise solution polymerization. Seen from the particle size: Emulsion particle Resin water dispersion particle size> Aqueous solution particle size. From the perspective of application, the two are the most important.
Acrylic emulsion is mainly used as the base material for latex paints, and it occupies an important application in the architectural coatings market. Currently, its application is still expanding. In recent years, the development and application of acrylic resin water dispersion have attracted increasing attention. In industrial coatings, civil use The application of coatings continues to expand. According to the monomer composition, it is usually divided into pure acrylic emulsion, styrene-acrylic emulsion, vinegar-acrylic emulsion, silicon-acrylic emulsion, tertiary vinegar (tertiary carbonate-vinyl acetate) emulsion and tert-propylene (tertiary carbonate-acrylate) emulsion.
