Abstract

The invention discloses a water-proof back adhesive for stone. The adhesive consists of a liquid component and a powder component in a weight ratio of 1:1-3, wherein the liquid component comprises 20 to 95 percent of acrylic ester emulsion, no more than 5 percent of antifoaming agent, no more than 4 percent of preservative and 4 to 75 percent of water; and the powder component comprises at least two of 0 to 70 percent of cement, 0 to 70 percent of quartz sand and 0 to 70 percent of calcium carbonate. The water-proof back adhesive for the stone slows down stone weathering by reducing the immersion of water and other harmful substances into the stone and has high bonding performance with a substrate during wet combining construction, so that the stone is free from phenomena such as efflorescence, water stain, flaking, hollowing, falling, cracking and the like.

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...
