Water-based unsaturated polyester resin and preparation method thereof
The invention belongs to the technical field of high molecular materials and relates to water-based unsaturated polyester resin and a preparation method thereof. The water-based unsaturated polyester resin is prepared from the following raw materials in parts by weight: 180-230 parts of polylol, 250-310 parts of unsaturated polyacid, 0-40 parts of saturated polyacid, 210-280 parts of air drying agent, 0.2-0.8 part of antioxidant, 0.5-1 part of catalyst, 0.04-0.08 part of polymerization inhibitor, 32-65 parts of neutralizing agent, 130-260 parts of cosolvent and 400-570 parts of pure water. The water-based unsaturated polyester resin has the advantages that the water-based unsaturated polyester resin can be diluted with water; the prepared lacquer is low in VOC discharge and flexible in construction; the water-based unsaturated polyester resin has low cost, net flavor and air drying property and can be cured at normal temperature or cured by heating; and the water-based unsaturated polyester resin is used for replacing the traditional resin for traditional oil paint products and has wide application prospects.
