The invention relates to the technical field of adhesives, and particularly provides the transparent acrylate structural adhesive and the preparation method thereof.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a transparent acrylic structural adhesive and a preparation method thereof. Background technique [0002] With the development of the times and the continuous improvement of product requirements, the existing acrylate structural adhesives have high bonding strength, extensive bonding performance, fast curing at room temperature, excellent weather resistance and stability, and good comprehensive performance. [0003] At present, there are many types of acrylic structural adhesives, such as high toughness, high strength, high thermal conductivity, high and low temperature resistance, etc. Transparency Structural products have high transparency requirements for appearance applications, and at the same time need to maintain the original high strength and toughness requirements, which cannot be fully met by existing products. Contents of the invention [0004] In view of the abov...
