Problems solved by technology

Due to its good mechanical properties, electrical insulation, chemical resistance, small shrinkage, good stability, and high adhesion, epoxy resin can be used as coatings, adhesives, composite resin matrix, electronic materials, etc. Packaging materials, etc., are widely used in machinery, electronic appliances, aerospace and other fields. However, due to the characteristics of its cross-linked network structure, the adhesive made of it has high brittleness after curing, poor peel strength, and poor durability. The defects of poor thermal properties and antibacterial properties limit its application to a certain extent

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an epoxy resin adhesive containing graphene oxide. Background technique [0002] Epoxy resins generally refer to molecules containing two or more epoxy groups, with organic compounds such as aliphatic, alicyclic or aromatic as the skeleton, and can be used in appropriate chemical reagents (curing agents) through epoxy groups. ) in the presence of a general term for compounds that react to form a three-dimensional network cured product. Due to its good mechanical properties, electrical insulation, chemical resistance, small shrinkage, good stability, and high adhesion, epoxy resin can be used as coatings, adhesives, composite resin matrix, electronic materials, etc. Packaging materials, etc., are widely used in machinery, electronic appliances, aerospace and other fields. However, due to the characteristics of its cross-linked network structure, the adhesive made of it has high...
