Abstract

The invention discloses heat-resistant unsaturated polyester resin. The heat-resistant unsaturated polyester resin comprises the following raw materials in parts by weight: 30-40 parts of phthalic anhydride, 5-15 parts of maleic anhydride, 20-40 parts of m-phthalic acid, 2-10 parts of fumaric acid, 8-16 parts of lauric acid, 1-6 parts of benzoic acid, 12-25 parts of tung oil anhydride, 50-80 parts of diglycol, 10-30 parts of propylene glycol, 5-15 parts of styrene, 20-40 parts of alpha-methyl styrene, 1-4 parts of a stabilizer, 0.1-0.8 part of hydroquinone, 5-15 parts of epoxy resin, 1-5 parts of nano-silicon dioxide and 1-4 parts of modified sodium acrylate. The heat-resistant unsaturated polyester resin has good heat resistance and antibacterial and anti-mold effects, high mechanical strength and remarkable aging resistance.

Description

technical field [0001] The invention relates to the technical field of unsaturated polyester resins, in particular to a heat-resistant unsaturated polyester resin. Background technique [0002] Unsaturated polyester resin is a kind of thermosetting material, which is the most commonly used thermosetting resin in the field of anchoring agent. Ordinary unsaturated polyester resin generally only adopts dibasic acid and dibasic alcohol polycondensation reaction, and adds styrene to dilute at the same time to form A linear polymer compound with ester bonds and unsaturated double bonds. The unsaturated polyester resin prepared by this traditional method is relatively unsatisfactory in terms of bonding and wetting. Meet the application requirements of some products and stone processing. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a heat-resistant unsaturated polyester resin, which has g...
