Abstract

The invention discloses a vinyl resin which comprises the following materials in parts by weight: 385-415 parts of epoxy resin, 71.4-75.4 parts of organic acid, 0.06-0.10 part of accelerator, 0.18-0.26 part of polymerization inhibitor and 107.2-132.98 parts of solvent. The preparation method comprises the following steps: mixing the epoxy resin and polymerization inhibitor, and slowly and dropwisely adding the acrylic acid monomer premixed with the accelerator, thereby obtaining the high-solid-content low-viscosity vinyl resin through technical control. The leveling property of the vinyl resin is obviously improved, the flexibility, light resistance, chalking resistance are improved, application efficiency is enhanced by more than 100%, and the service life is prolonged by 50%. The invention also discloses a preparation method of the vinyl resin.

Description

technical field [0001] The invention relates to the field of resin synthesis, in particular to a vinyl resin and a preparation method thereof. Background technique [0002] Vinyl resin is an internationally recognized highly corrosion-resistant resin, which is an unsaturated polyester resin with a special structure that is soluble in styrene liquid and contains unsaturated double bonds. Standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin, which has the following characteristics: [0003] 1. The double bonds at both ends of the molecular chain are extremely active, so that the vinyl resin can be cured quickly, and the strength of use can be obtained quickly, and a polymer with high corrosion resistance can be obtained; [0004] 2. Synthesized by methacrylic acid, the methyl group on the side of the ester bond can protect and improve the hydrolysis resistance; [0005] 3. The resin contains less ...
