Abstract

The invention discloses a corrosion resistant unsaturated polyester resin, and belongs to the technical field of preparation of resins. The corrosion resistant unsaturated polyester resin comprises the following raw materials: unsaturated polyester resin, organic silicon resin, trimethyl phosphate, alkide resin, dicyclopentadiene, dibutyltin oxide, isophthalic anhydride, triiso-tricyanurate ester,polycarbonate, cobalt iso-octoate, cobalt cyclopentanecarboxylate, hexafluorobutyl methacrylate, methyl ethyl ketone peroxide, oleic acid, dibutyltin oxide, hexafluorobutyl methacrylate, trihydroxymethyl propane diallyl ether, castor oil, precipitated barium sulphate, glass flake, cellulose acetate, zinc acetate, a silane coupling agent KH-560, and a corrosion resistant modified auxiliary, and the corrosion resistant unsaturated polyester resin is prepared by the steps of preparing a matrix, preparing a modified material, mixing the matrix and the modified material, etc. The prepared unsaturated polyester resin has an excellent property of corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of resin preparation technology, in particular to a corrosion-resistant unsaturated polyester resin and a preparation method thereof. Background technique [0002] Unsaturated polyester is a kind of mature and industrialized thermosetting resin, and the corresponding products are widely used in laminates, building materials, adhesives, coatings, construction industry and electric power industry. Unsaturated polyester raw materials have wide sources and low cost; they can be cured at room temperature, the curing time is controllable, and the molding process is simple; after curing, the surface of the product is bright and plump, with high hardness, good wear resistance, excellent electrical properties and weather resistance. Although unsaturated polyesters have many advantages, there are also some disadvantages. For example, traditional unsaturated polyester materials are usually brittle, poor in toughness, ...
