Description

technical field [0001] The invention belongs to the technical field of unsaturated polyester resins, and in particular relates to a modified unsaturated polyester resin with excellent aging resistance 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. [0003] The anti-aging properties of unsaturated polyester resins in the prior art cannot meet the needs in actual production, so it is urgent to design ...
