Graphene repairing waterproof paint for concrete crack

Abstract

The invention discloses graphene repairing waterproof paint for a concrete crack. The graphene repairing waterproof paint is prepared from the following components in parts by weight: 50 to 58 parts of portland cement, 15 to 25 parts of vitrified micro bead powder, 4 to 8 parts of water repellent, 5 to 10 parts of acrylic latex powder, 10 to 15 parts of graphene nanosheet, 15 to 25 parts of quartzsand, 1 to 2 parts of glass chopped silk, 0.05 to 0.1 part of antifoaming powder and 0.5 to 1 part of filling material. Relative to existing repairing waterproof paint for the concrete crack, the graphene repairing waterproof paint is enhanced in performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a waterproof coating for repairing cracks in graphene concrete. Background technique [0002] With the vigorous development of the building decoration industry, it is not uncommon for concrete cracks to appear in buildings. The original method of concrete crack treatment is: mix the two-component organic polymer waterproof coating in proportion, and inject the cracks with a high-pressure grouting machine. , Penetrate into small cracks in the rock mass, produce a polymerization reaction, form a solid reinforcement, and the filling foams. However, because it is an organic material, it will shrink within a certain period of time, so it will seep water, shorten the service life, and increase maintenance costs. [0003] Later, people used paint to repair the gaps. However, the commonly used gap repair paints have short service life, high cost, and difficult work...

Problems solved by technology

[0002] With the vigorous development of the building decoration industry, it is not uncommon for concrete cracks to appear in buildings. The original method of concrete crack treatment is: mix the two-component organic polymer waterproof coating in proportion, and inject the cracks with a high-pressure grouting machine. , Penetrate into the small cracks of the rock mass, produce a polymerization reaction, form a solid reinforcement, and the filling foams, but because it is an organic material, it will shrink within a certain period of time, so it will seep water, the service life will be short, and the maintenance cost will be increased

[0003] Later, people used paint to repair the gaps. However, the commonly used gap repair paints have short service life, high cost, and difficult work, resulting in their service life being far shorter than that of concrete. High-pressure injection with two-component polymer waterproof paint After a period of time, the pulp is prone to shrinkage

Moreover, common caulking coatings, because they do not pay attention to the relationship between composition and performance, often lead to serious water seepage of grouting materials after a period of use, which seriously affects the normal service life of concrete and steel bars, and users are helpless. not repatching it
