Problems solved by technology

But at present, the industrial preparation of water-based acrylic pre-emulsion is to use water to dissolve the emulsifier and then add acrylic acid monomer for emulsification. It is restricted by the water solubility of non-ionic emulsifiers, and it takes a long time to dissolve. The prepared acrylic pre-emulsion is easy to separate. , poor stability of acrylic resin emulsion

Abstract

The invention discloses a water-based acrylic resin. The water-based acrylic resin comprises the following components in parts by weight: 30-32 parts of ethyl acrylate, 10-12 parts of butyl acrylate, 4-5 parts of methyl methacrylate, 1 part of methacrylic acid, 1 part of hydroxyethyl methacrylate, 0.4-1 part of diacetone acrylamide, 0.1-0.3 part of oxalyl dihydrazide, 1 part of triethanolamine, 0.2 part of potassium persulfate, 1.5 parts of butyl palmitate, 2-3 parts of a surfactant, 0.05 part of a defoamer, 0.01 part of a preservative and 40-45 parts of water medium. The water-based acrylic resin is prepared by chemically mixing a pre-emulsion; the elasticity, water resistance, soundness and other indexes of the water-based acrylic resin meet requirements; the prepared adhesive slurry is thick in film, good in fastness, high in water resistance, non-stick in surface, good in stability and extremely environment-friendly; therefore, the water-based acrylic resin is ideal water-based resin.

Description

technical field [0001] The invention aims at the field of chemical industry, and in particular relates to a water-based acrylic resin and a preparation method thereof. Background technique [0002] Acrylic resin, the English name is Acrylic acid Polymers, the Chinese alias is acrylic resin emulsion, the molecular formula is (C 3 h 4 o 2 )n, used to prepare leather and some high-end products as finishing agents, to prepare acrylic resin paints, etc., is a chemical intermediate. Compared with traditional solvent-based coatings, water-based coatings have the advantages of low price, safe use, saving resources and reducing environmental pollution, so they have become the main direction of the current development of the coatings industry. Water-based acrylic resin coatings are the fastest-growing and most diverse non-polluting coatings among water-based coatings. Waterborne acrylic resins include acrylic resin emulsions, acrylic resin aqueous dispersions and acrylic resin aqu...
