Abstract

The invention relates to a high-temperature bar planting glue, which comprises the following components in parts by weight: a material A: 18-22 parts of epoxy resin, 3-4 parts of a diluent, 0.50-0.55 part of white carbon black and 18-18.5 parts of silica powder; and a material B comprises the following components in parts by weight: 10-12 parts of a curing agent, 0.1 part of a coupling agent, 0.70-0.75 part of white carbon black, 14.5-15 parts of silica powder and 0.04-0.06 part of color paste. According to the technical scheme, the high-temperature type bar planting glue is solvent-free and bi-component resin glue, and the problems that an existing bar planting glue is poor in infiltration effect, weak in adhesive force, poor in high-temperature resistance and low in bonding strength can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of rebar-planting glue, in particular to a high-temperature type rebar-planting glue. Background technique [0002] Chemical method planting tendons, referred to as planting tendons, also known as planting tendons. It is to drill holes in concrete, wall rocks and other base materials, then inject anchoring glue, and then implant ordinary steel bars or bolts. After the glue is cured, the steel bars or bolts will be integrated with the base material to achieve reinforcement. The role of reinforcement is to strengthen the connection between concrete and steel bars, so that the two can work together to bear various stresses. [0003] The performance of the planting glue varies according to the conditions of use. In humid climates, the planting glue is required to resist the humid environment, and in the high temperature environment, the planting glue is required to meet the high temperature resistance requireme...
