Abstract

The invention discloses a special steel bar embedding adhesive for steel bar and concrete anchoring and belongs to the technical field of building materials. Polyvinyl alcohol and acetic acid solutionare heated and stirred for dissolution, and a dissolved solution is obtained; beeswax is melted, and heated and stirred with the dissolved solution, emulsifier is added dropwise, emulsification is performed, and a formaldehyde solution is added dropwise; after heating and stirring reaction, ammonia is added dropwise to adjust pH; an epichlorohydrin solution is added, heating reaction is performed, ammonia is added to maintain the pH, a reaction solution is obtained, and filtering and washing are performed to obtain vinyl alcohol resin; the polyvinyl alcohol resin, pig hair powder, milk, emulsifier and water are stirred, and an organic mixture is obtained; silicate solution, Portland cement, water reducing agent, magnesium sulfate whisker, calcium sulfate, silane coupling agent and raney nickel are stirred, and an inorganic mixture is obtained; the organic mixture and the inorganic mixture are stirred, and the special steel bar embedding adhesive for steel bar and concrete anchoring isobtained. The special steel bar embedding adhesive for steel bar and concrete anchoring has excellent water resistance and mechanical properties.

Description

technical field [0001] The invention discloses a reinforcement glue specially used for anchoring steel bars and concrete, which belongs to the technical field of building materials. Background technique [0002] Rebar planting refers to a technology that drills holes, injects glue, inserts steel bars on the existing structure, and anchors the steel bars in the structure after the glue is cured. Rebar anchoring technology has the characteristics of convenient construction, simple process, good adaptability, time saving, reliability and flexibility, etc. It is widely used in projects such as adding layers, such as the post-anchoring of steel bars and bolts in concrete components, the fixing of curtain wall brackets, the fixing of various equipment foundations, the anchoring connection of steel structures and concrete structures, etc. [0003] Rebar anchoring technology is one of the important means to implement building renovation, structural reinforcement, and equipment inst...
