Description

technical field [0001] The invention relates to a graphene-modified unsaturated polyester resin glue and a preparation method thereof, belonging to the technical field of polymer materials and environmental protection. Background technique [0002] Unsaturated polyester resin is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid diols. Unsaturated polyester resin has the characteristics of low price and wide application, and has been widely used, especially in my country, which is a big country in the production and use of unsaturated polyester resin. Unsaturated polyester resin has been widely used in construction, anti-corrosion, yacht, furniture coating and other fields. [0003] However, compared with resins such as epoxy resin and furan resin, unsaturated polyester resin is still lacking in corrosion resistance. In addition, it also has defects such as ...
