Aqueous acrylic resins include acrylic resin emulsions, aqueous acrylic resin dispersions (also referred to as water-dilutable acrylic acid), and aqueous acrylic resin solutions. Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, saving resources and energy, reducing environmental pollution and pollution, and have become the main direction of the current development of the coating industry. Waterborne acrylic resin coatings are the fastest growing and most varieties of non-polluting coatings in waterborne coatings.

Aqueous acrylic resins include acrylic resin emulsions, aqueous acrylic resin dispersions (also referred to as water-dilutable acrylic acid), and aqueous acrylic resin solutions. Emulsions are mainly synthesized by emulsifying olefinic monomers in water initiated by aqueous free radical initiators, while aqueous resin dispersions are synthesized by different processes such as free radical solution polymerization or stepwise solution polymerization. In terms of particle size, emulsion particle size> resin aqueous dispersion particle size> aqueous solution particle size. From the application of the previous two is the most important.
Acrylic water-based paint can be divided into water dispersion and water-soluble two categories, the former is based on water emulsion or hydrosol as the matrix coating. Water-soluble acrylate coatings are made of copolymer resins with active cross-linkable functional groups, and multi-series thermosetting coatings are used to add or not cross-linked resins during the paint making process, so that the active functional groups are cross-linked during the film formation to form a paint film with a type structure. The development of water-based acrylate coatings can ensure the performance of acrylate coatings under the conditions of a variety of unique, most of the organic volatile solvents replaced by water, so as to achieve a significant reduction in air pollution purposes.
