Description

technical field [0001] The invention relates to the technical field of structural adhesives, more specifically, the invention relates to a high-strength structural adhesive for bonding rubber and concrete and a preparation method thereof. Background technique [0002] Ordinary glue cannot achieve firm bonding with rubber and concrete at the same time due to its low colloidal strength. Non-structural adhesives have low strength and poor durability, and can only be used for ordinary and temporary bonding, sealing, and fixing, and cannot be used for bonding structural parts. [0003] The structural adhesive has high strength, anti-stripping, impact resistance, and simple construction process. It is used for the bonding of metal, ceramics, plastic, rubber, wood and other materials of the same kind or between different kinds of materials, and can partially replace traditional connection forms such as welding, riveting and bolting. The stress distribution on the joint surface is...
