Problems solved by technology

[0003] At present, the waterproofness of the crack glue used for repairing concrete cracks is not strong, and the infiltration of water will not only make the crack difficult to sew and crack again
At the same time, if the waterproof measures are not done well, it will easily lead to the instability of the building.

Abstract

The invention discloses a waterproof type concrete crack adhesive which comprises the following raw materials in parts by weight: 30-80 parts of epoxy resin, 5-35 parts of polysulfide rubber, 10-40 parts of an alkali amino curing agent, 1-15 parts of polystyrene, 1-12 parts of coumarone, 1-8 parts of titanium dioxide, 1-10 parts of crylic acid, 2-15 parts of ethylene glycol monoethyl ether acetate, 1-10 parts of butanediol, 4-20 parts of ethyl acetate, 1-8 parts of tert-butyl peroxybenzoate, 1-10 parts of attapulgite powder, 1-6 parts of a silane coupling agent, 1-7 parts of morpholine and 5-30 parts of aids. The adhesive is capable of effectively sealing cracks, effectively preventing water and preventing influence of moisture to cracks and wall surfaces.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a waterproof concrete crack glue. Background technique [0002] Concrete has the advantages of high strength, good durability, and low price, and is widely used in the construction field. However, the porosity of concrete itself and the unavoidable defects existing in the interior of concrete make the impermeability of concrete poor. Studies have shown that water infiltration is the main cause of various diseases of concrete. The appearance of cracks accelerates the destruction of concrete structures. Although various concrete surface protective agents reduce the number of concrete cracks, it is almost impossible to completely eliminate concrete cracks. Therefore, repairing concrete cracks is an effective measure to prevent further expansion of concrete diseases. [0003] At present, the waterproofness of the crack glue used for repairing concrete cracks is not strong, and the infi...
