Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a molded resin for improving the insulation performance and thermal deformation temperature of outdoor electrical appliances and a preparation method thereof. Background technique [0002] Polyester resin is the abbreviation of unsaturated polyester adhesive. Unsaturated polyester adhesive is mainly composed of unsaturated polyester resin, initiator, accelerator, filler, thixotropic agent and so on. A linear structure (see linear polymer) polyester resin containing -CH=CH- double bonds in the main chain, which can be mixed with ethylenic monomers, such as styrene, acrylate, vinyl acetate, etc., in Under the action of initiators and accelerators, it can be polymerized into insoluble and infusible products at room temperature. Polyester resin is a general term for polymer compounds formed by polycondensation of diols or dibasic acids or polyols and polybasic acids. Polyester res...
