Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly structural adhesive and a preparation method thereof. Background technique [0002] Structural adhesives, referred to as structural adhesives, generally refer to the components used to bond the body under stress, and are adhesives that require relatively high mechanical strength (especially impact peel strength) and durability. It is generally used for structural bonding of stressed parts such as tension, shear, impact and vibration. It has the advantages of high strength, anti-stripping, impact resistance, and simple construction technology. It is used in aerospace, rail vehicles, ships, and automobiles. have a wider range of applications. [0003] At present, there are epoxy resin, bismalay resin and cyanate resin structural adhesive films on the market, which can meet the application requirements in terms of mechanical strength, but the product h...
