Abstract

The invention discloses a repairing material for building wall cracks, which comprises the following raw materials: 0.1-0.3 parts of silicon dioxide, 0.2-0.4 parts of talcum powder, and 0.1-0.3 parts of silicate double salt , 0.04-0.08 parts of inorganic minerals, 2.5-8 parts of cement clinker, 1-4 parts of hydroxypropyl methylcellulose, 3-25 parts of sodium tripolyphosphate, and 1-5 parts of polypropylene short fiber 2-8 parts for mixed materials, 1-11 parts for gypsum, 0.4-3 parts for grinding aids, 0.2-4 parts for superfine admixtures and 5-28 parts for water. The repairing material for building wall cracking of the present invention has a high degree of adhesion, can repair cracks at one time, is not easy to repeatedly appear cracks, is not easy to fall off and produce hollowing, and can prevent the wall from returning to alkali; the use method is simple and time-saving Labor-saving, labor-saving and material-saving; raw materials are easy to buy, and the market price is low.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a repairing material for building wall cracks. Background technique [0002] Due to thermal expansion and cold contraction, cracks in the wall are more and more common. When dealing with the problem of wall cracking in the prior art, a part of the wall covering on both sides of the crack is shoveled off, painted with latex, and then pasted on a hanging wall. Net, and finally paint a layer of paint on the hanging net. However, cracks will continue to appear after some cracks are repaired, which seriously affects the construction quality and brings safety hazards to the living environment. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] Aiming at the problems existing in the prior art, the object of the present invention is to provide a repairing material for building wall cracking, which can solve the probl...
