Description

technical field [0001] The invention relates to an acrylic structural adhesive with good weather resistance and stability and a preparation method thereof, belonging to the field of adhesives. Background technique [0002] The second-generation Structural Acrylic Adhesive (SGA) is a reactive two-component adhesive, which has the characteristics of rapid curing at room temperature, high strength, good toughness, and oily surface bonding. It is widely used in aviation, automobiles, machinery, electronic appliances, etc. , instrumentation, construction, furniture, toys and other industries of structural bonding. [0003] At present, the particularity of the use environment of some electronic products requires that the adhesive has good performance such as high and low temperature resistance, humidity and heat aging resistance, etc., and requires fast curing and relatively long operating time during the application process. Ordinary Acrylic structural adhesives are difficult to...
