Abstract

The invention discloses an anti-tensile composite steel adhesive and belongs to the technical field of building structure adhesives. Zeolite is subjected to ball milling and sieved, and refined zeolite is obtained; the refined zeolite and a gelatin liquid are subjected to ultrasonic mixing, filtering and drying, a dried filter cake is obtained, the dried filter cake and tetraethoxysilane are mixedand subjected to vacuum impregnation and filtration, filtered residues are obtained, carbonized and cooled, and a modified auxiliary material is obtained; cork powder, carbomer 934, biogas slurry, saccharose and water are mixed and fermented, ammonia water is dropwise added to adjust pH, filtration, drying and carbonization are performed, a carbonized material is obtained and mixed with a low-melting-point alloy, the mixture is subjected to ball milling, and a modified additive is obtained; epoxy resin, a diluent, unsaturated polyester resin, drying oil, the modified additive, a plasticizer,the modified auxiliary material, the curing agent and a coupling agent are mixed and stirred, and the anti-tensile composite steel adhesive is obtained. The provided anti-tensile composite steel adhesive has excellent mechanical performance.

Description

technical field [0001] The invention discloses a stretch-resistant composite steel adhesive, which belongs to the technical field of building structural adhesives. Background technique [0002] Engineering structure reinforcement is an emerging industry, which refers to the necessary structural transformation and reinforcement when the structural system of a building or structure cannot meet the requirements of use. In engineering structure reinforcement, bonded steel reinforcement is a common engineering reinforcement technology. In bonded steel reinforcement, concrete is a common base to be reinforced. In concrete reinforcement, structural adhesives are needed to bond the concrete base and steel to be reinforced. , so that it becomes a unified whole, and then bear the force together to play a role in structural reinforcement. In the reinforcement of bonded steel with concrete as the base material, GB50728-2011 puts forward clear requirements for the basic performance of t...
