Abstract

The invention relates to water-soluble acrylic resin and a preparing method thereof, and relates to the technical field of chemical raw materials. The water-soluble acrylic resin is prepared from methyl methacrylate, n-butyl methacrylate, acrylic acid, n-butyl acrylate, 2-ethylhexyl acrylate, methyl isobornyl acrylate, hydroxy-propyl acrylate, dibenzoyl peroxide, water, a neutralizing agent and isobutyl alcohol. The water-soluble acrylic resin is formed by (methyl) methacrylate monomers as a main raw material through chemical polymerization. According to the water-soluble acrylic resin and the preparing method thereof, the water-soluble acrylic resin can be matched with curing agents such as fully etherificated amino resin and closed isocyanate to prepare outdoor environment-friendly paint, and a paint film has excellent salt mist resistance, ageing resistance, self-cleaning performance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of chemical raw materials, in particular to a water-soluble acrylic resin and a preparation method thereof. Background technique [0002] Water-soluble acrylic resins include acrylic resin emulsion, acrylic resin aqueous dispersion (also known as water dilutable acrylic acid) and acrylic resin aqueous solution. Emulsions are mainly synthesized by emulsifying oily ethylenic monomers in water under the initiation of water-based free radical initiators, while resin aqueous dispersions are synthesized by different processes such as free radical solution polymerization or stepwise solution polymerization. From the perspective of particle size: emulsion particle size > resin aqueous dispersion particle size > aqueous solution particle size. [0003] Acrylic emulsion is mainly used as the base material of latex paint, and it occupies an important application in the architectural coatings market. At present, ...
