Problems solved by technology
[0011] Most of the existing flame-retardant gel coat resins in the domestic market are synthesized from halogen-containing acids such as HET acid or tetrabromophthalic anhydride, and are formulated with reactive unsaturated polyester resins as the matrix. Flammability, but the weather resistance is not very ideal, it will turn yellow obviously after a short period of exposure to the sun, it is difficult to meet the requirements for the production of white or light-colored FRP products

Abstract
The invention relates to a flame retardant black gel coat for piano and a preparation method thereof. The gel coat is mainly composed of flame retardant epoxy vinyl resin taken as the resin matrix, color paste, thixotropic agent, filling material, promoter, crosslinking monomers, and levelling agent, and is prepared by the steps of stirring in steps, rolling and pressing, and vacuumizing. The black gel coat has a good flame retardant performance, good thixotropic property, moderate viscosity, and short post curing time, is suitable for spraying technology, and does not have the sagging phenomenon. The product has an excellent scratch resistant performance and weatherability.
Description
technical field [0001] The invention relates to a flame-retardant gel coat and a preparation method, in particular to a black gel coat for piano panels and a preparation method. Background technique [0002] Vinyl Ester Resins is an internationally recognized highly corrosion-resistant resin. The standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin. It has been dissolved in styrene solution. This type of resin 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 ester bonds, 35-50% less per mole th...
