Waterproof gum for stone

Abstract

The invention discloses a waterproof gum for stone. The waterproof gum is composed of liquid components and powdery components in a weight ratio of 1:(1-3), wherein the liquid components comprise 20-95% of acrylate emulsion, not more than 5% of antifoaming agent, not more than 4% of preservative and 4-75% of water; the powdery components comprise 0-70% of cement, 0-70% of quartz sand and 0-70% of calcium carbonate; and the powdery components comprise at least two of cement, quartz sand and calcium carbonate. By the adoption of the waterproof gum for the stone, disclosed by the invention, immersion of water and other harmful substances on the stone is reduced, so that the weathering of the stone is slowed down; and meanwhile, a good bonding performance is existent between the waterproof gum and base courses in the wet-sticking construction process, so that the phenomena, such as efflorescence, waterlogging, peeling, hollowing, dropping and cracking, on the stone are prevented.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a stone waterproof adhesive. Background technique [0002] Stone includes natural stone and artificial stone. It is a good decorative material for interior decoration and has many decorative effects, such as showing nobility, firmness, and beauty. However, due to different causes of many natural stones, there are many gaps and holes invisible to the naked eye in the stone, which will make the stone have a certain degree of water absorption, and even seep water to absorb harmful substances in the environment, accelerate the weathering of the stone, and affect the decorative effect and use. life. [0003] In actual use, "stone protective agent" is often painted on the surface of the stone to "protect" the stone. Stone protective agents are generally silicone or fluorocarbon materials. After being applied to the stone surface, they can go deep into the crevices and holes and form...

AI Technical Summary

Problems solved by technology

After being treated with stone protective agent, the protective effect on the surface and side of the stone is better, but the back (adhesive surface) of the stone is poorly compatible with the cement-based adhesive during wet paste construction, and the bonding performance is greatly reduced. It is easy to cause the stone to have shells, hollows, shedding, cracking, etc.; if it is not treated with stone protective agents, it is easy to cause white blooms, water stains, etc. on the surface of the stone
