Abstract

The invention provides a reactive waterproof coating. The reactive waterproof coating is a waterproof coating which can be chemically and physically crosslinked with cement. The coating comprises, by weight, rubber latex, emulsified asphalt and a waterproof bridging agent. One end of the waterproof bridging agent in the above product reacts with unsaturated C=C double bond, a carboxyl group -COOH and a hydroxyl group -OH in rubber latex and the emulsified asphalt to realize connection, the other end of the waterproof bridging agent is combined with hydrated calcium silicate or calcium aluminate generated in the cement hydration process to form a chemical bond, the bridging agent and concrete undergo a chemical crosslinking reaction to tightly combine the rubber, the asphalt material and cement, associated positions have chemical bonds like an erected waterproof bridge and have an irreversible bonding effect after curing, and the asphalt is combined with the rubber to solidify a coating layer so as to keep asphalt adhesiveness and have the elasticity, the weatherability and other performances of the rubber after solidification. The coating is an aqueous environmentally-friendly coating, and has the advantages of convenient construction and excellent social and economic benefits.

Description

technical field [0001] The invention relates to a reactive waterproof coating, which is a water-based rubber waterproof coating capable of chemically reacting with cement concrete to produce chemical crosslinking. Background technique [0002] Water-based rubber waterproof coating is a coating with waterproof function that is made of high molecular polymer material as the main film-forming substance, adding emulsifier, water and some additives, and then processed by special technology. It has excellent high elasticity, excellent high and low temperature performance and waterproof performance. Rubber waterproof coating has excellent performance, but the disadvantage is that it is more expensive. Asphalt is a waterproof, moisture-proof, anti-corrosion, and cheap organic gelling material, but asphalt is easy to flow at high temperature and brittle at low temperature, and asphalt is solid at room temperature, so it is inconvenient to construct, so people make emulsified asphalt...
