Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a special back water pressure repairing coating with double waterproof effects for a basement.
Background
Because the main body of the basement of the building is mostly of a concrete structure, capillary holes and shrinkage-compensating cracks are easy to appear in the concrete in the solidification process, and leakage generally appears, a plugging mode of a water-back surface is generally adopted, and the existing market is used for basement base surface water seepage dietary modification materials and mainly comprises organic grouting foaming and inorganic permeable crystallization.
At present, an invention patent with a patent number of CN201810589064.8 discloses a back water pressure waterproof coating for leakage stoppage and leakage resistance of a back water surface, which comprises the following substances in parts by weight: 400-500 parts of Portland cement; 350-480 parts of sand filler; 20-50 parts of latex powder; 5-10 parts of a waterproof agent; 10-50 parts of a coagulant; 20-50 parts of active master batch; 2-10 parts of a thixotropic agent; 2-5 parts of fibers; 0-2 parts of cellulose ether; 1-3 parts of a defoaming agent; 1-10 parts of pigment. The coating can penetrate into capillary holes and micro cracks of a building through a carrier, and is dried, expanded and crystallized to block the capillary holes and the micro cracks to form a tough anti-seepage leakage blocking layer, but the coating does not have a double waterproof effect, has small reverse water seepage action in a state that open water exists on a base surface and the reverse water seepage is slow under high pressure, and has poor hardness, poor corrosion resistance and short service life.
Therefore, in order to solve the problem of poor waterproof effect, it is necessary to improve the use scenario of the back hydraulic repair coating.
