The invention discloses a concrete adhesive, which is prepared from the following raw materials in parts by weight: 3-8 parts of lithium silicate, 6-8 parts of an enhancer, 7-11 parts of vinylidene chloride, 6-10 parts of dichloroethane, 5-10 parts of acetone, 5-11 parts of imide, 3-10 parts of dibutyl phthalate, 4-9 parts of emulsified asphalt, 6-8 parts of an ethylene-acrylic acid copolymer, 3-6 parts of ester ring aldehyde, 5-10 parts of dimeric epoxy pentadiene, 4-8 parts of aluminum oxide, 9-15 parts of acrylic resin and 6-8 parts of epoxy resin. The concrete adhesive disclosed by the invention has the beneficial effects of high bonding strength, and no loosening or crack, and is capable of effectively restoring concrete.
Description
technical field [0001] The present invention relates to a concrete adhesive. Background technique [0002] Among the concrete buildings and structures, due to design and construction defects and aging, damage and disasters in the long-term use process, the concrete structure cracks, poor seismic performance, insufficient bearing capacity, etc. affect its safety and use functions. The method is to frequently sprinkle water on the concrete surface for maintenance or repair. But these methods are all cumbersome, and the operation is not very convenient. Adhesives can be added to concrete to enhance the adhesion between concrete, which can effectively prevent concrete cracking. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a concrete adhesive which has high bonding strength and can effectively repair concrete without loosening or cracking. [0004] In order to solve t...
