Description

technical field [0001] The invention relates to the technical field of unsaturated polyester resins, in particular to a flame-retardant and corrosion-resistant modified 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...
