Abstract

The invention discloses a building reinforcing epoxy adhesive and a preparation method thereof, and belongs to the field of building adhesives, and the building reinforcing epoxy adhesive comprises the following components by weight: 50-70 parts of epoxy resin; 5-10 parts of a curing agent; 1-5 parts of an accelerant; 8-15 parts of a diluent; 2-8 parts of aluminum hydroxide; 1-4 parts of filler. Aluminum hydroxide which is slow, durable and strong in acid resistance and has convergence and mucous membrane protection effects is added to be combined with other added raw materials, the prepared adhesive is high in strength and toughness, meanwhile, the flame-retardant function is added to the adhesive, the reaction of the adhesive can be promoted by adding ethyl acetate with solubility and quick-drying performance, and the adhesive has a good application prospect. According to the preparation method, the reaction speed of the adhesive is increased, and then the adhesive can be diluted byadding butanol which can be mixed and dissolved with various organic solvents, so that the concentration of the adhesive is reduced, the functions of the adhesive are increased, and the practicabilityof the adhesive is enhanced.

Description

technical field [0001] The invention belongs to the technical field of building adhesives, and in particular relates to a building reinforcement epoxy adhesive and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, the economic loss caused by the damage of concrete structures caused by various reasons is astonishing. Therefore, it is necessary to repair, update and transform the concrete structure. Now the common repairs include crack injection, steel plate reinforcement, and prestressing. method, carbon fiber reinforcement method and reinforced concrete reinforcement method, etc., the above reinforcement methods must be matched with the corresponding adhesive, the adhesive has excellent mechanical properties, aging resistance, water resistance, chemical medium resistance and good acid and alkali resistance Performance plays an important role in synthetic adhesives, but the strength and toughness of the adhesi...
