Abstract

The invention relates to a bi-component high-temperature-resistant and low-temperature-resistant novel acrylate structural adhesive and a preparation method thereof. The structural adhesive comprisesa component A and a component B, wherein the component A comprises an acrylate monomer a, a polyimide oligomer, a flexibilizer, a stabilizer, a coupling agent, an accelerator and other assistants; andthe component B comprises an acrylate monomer b, a plasticizer, an oxidant and a polymerization inhibitor. The preparation method comprises the following steps: mixing the acrylate monomer a, the polyimide oligomer and the flexibilizer in proportion until the components are completely dissolved, adding the stabilizer, the accelerant and other assistants, uniformly mixing, adding the coupling agent, stirring, and defoaming to obtain the component A; uniformly mixing the acrylate monomer b, the plasticizer, the oxidant and the polymerization inhibitor, and defoaming to obtain the component B; when the structural adhesive is used, the component A and the component B are mixed to obtain the structural adhesive. The structural adhesive provided by the invention has excellent high and low temperature resistance, good stability, long storage time and simple preparation method; the sizing is easy to control and convenient to operate.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a novel two-component high- and low-temperature-resistant acrylate structural adhesive and a preparation method thereof. Background technique [0002] Acrylic structural adhesive is a reactive two-component adhesive, which has been widely used in structural bonding due to its simple process, fast curing at room temperature, good toughness, high strength, and oil surface bonding. [0003] With the development of the times and the continuous improvement of product requirements, the existing acrylic structural adhesives have high bonding strength, extensive bonding performance, fast curing at room temperature, excellent weather resistance and stability, and good comprehensive performance; Some products have high toughness and high strength; some products have low odor and so on. However, with the increasing application requirements of products, acrylic structural adhesive products need bet...
