Double-component wall surface structure crack repairing material and use method thereof

Abstract

The invention discloses a double-component wall surface structure crack repairing material and a use method thereof, wherein the double-component wall surface structure crack repairing material comprises a double-component wall surface structure agent divided into a component A and a component B; the component A is viscous liquid, the component B is powdery solid, and the component A and the component B are blended according to the proportion of (0.8-1):1 and stirred into uniform paste for use. The styrene-acrylic polymer emulsion contains high-flexibility polymer particles, the high-flexibility polymer particles and fillers such as cement, quartz sand and heavy calcium powder form a coated net-shaped structure under the action of various auxiliaries; meanwhile, the fibers are embedded in the coated net-shaped structure, the toughness of the material is enhanced, and the flexibility of the material can resist local wall activity; the material disclosed by the invention is high in adhesive force and can permeate into capillary pores of various base materials to form a hinge structure so as to resist activity difference among different materials; and the single-time batch scraping thickness of the material can reach 20 mm, the labor cost needed by construction is reduced, the material has the quick-drying performance, the single-time drying time is about 1 hour, and the maintenance man hour is shortened.

Description

technical field [0001] The application relates to the technical field of crack repair, in particular to a two-component wall structure crack repair material and its application method. Background technique [0002] Cracks on the wall can be divided into two categories, the other is the cracks that appear in the decoration, such as cracks caused by the difference in properties of different materials, cracks between gypsum boards or board walls, decoration plastering or putty materials caused by self-stress Cracks, etc.; the other type is structural cracks formed after problems with the building structure. [0003] The cracks that appear in the decoration can be divided into two categories according to the difficulty of repair. One is the cracks with small width and low activity in the later stage. After repairing, such cracks will basically not crack again; The first type is stubborn cracks with a large width and a large amount of activity in the later period. They are often...

AI Technical Summary

Problems solved by technology

[0004] Once the structural cracks of the building are found, they will be repaired by grouting and refilling mortar before decoration, but often with the continued settlement of the building, shrinkage of materials and other factors, most structural cracks will reappear, resulting in The decorative layer of the wall produces cracks; such stubborn cracks that are prone to secondary cracking have one thing in common, they all appear after the decoration is completed, resulting in complicated maintenance process, high cost and incomplete maintenance
