Abstract

The invention discloses an improved epoxy resin adhesive which comprises the following components in parts by weight: 65-85 parts of epoxy resin, 20-30 parts of aromatic amine curing agent, 5-15 parts of imidazole curing accelerator, 25-35 parts of nitrile rubber, 1-2.5 parts of coupling agent, 15-25 parts of diluent, 10-20 parts of phosphorus based flame retardant, 5-10 parts of plasticizer, 10-15 parts of calcium carbonate filler and an appropriate amount of organic solvent. According to the improved epoxy resin adhesive, the tenacity of the epoxy resin adhesive can be improved by means of the addition of the hydroxyl-terminated nitrile rubber. The phosphorus-containing flame retardant can influence the glue overflow amount and the shelf life and improve the flame retardance of the adhesive; the tenacity can be improved by the plasticizer. Therefore, the epoxy resin adhesive has favourable flame retardance and tenacity and relatively high viscosity.

Description

Technical field: [0001] The invention relates to an epoxy resin composition, in particular to an epoxy resin adhesive. Background technique: [0002] With the rapid development of industries such as automobiles and electronics, the selection of epoxy resin materials used in the automobile and electronics industries is particularly important. At present, the combination of many resins and curing agents requires flame-retardant properties, and it is difficult to coordinate the viscosity and heat resistance. Therefore, in order to meet market considerations, it is currently necessary to provide an epoxy resin adhesive with good Flame retardant, heat resistance and viscosity properties. Invention content: [0003] The object of the present invention is to provide an improved epoxy resin adhesive, which has good toughness, flame retardancy, heat resistance and viscosity. [0004] In order to achieve the above object, an improved epoxy resin adhesive of the present invention i...
