Embodiment 1

[0023] Take 20 parts of styrene-butadiene rubber latex with a solid content of 42 ± 0.5%, add 30 parts of styrene-butadiene rubber modified emulsified asphalt with a solid content of 42 ± 0.5% and 0.2 parts of vinyl triacetoxysilane under normal temperature stirring, and stir evenly. A reactive waterproof coating is obtained.

Embodiment 2

[0025] Take 30 parts of neoprene latex with a solid content of 50±0.5%, add 20 parts of neoprene modified emulsified asphalt with a solid content of 50±0.5% and 0.6 parts of N-phenyl-3-aminopropyl Trimethoxysilane, stir evenly to get reactive waterproof coating.

Embodiment 3

[0027] Take 40 parts of SBS rubber latex with a solid content of 60±0.5%, add 60 parts of emulsified asphalt with a solid content of 60±0.5% and 1 part of γ-chloropropyltriethoxysilane under normal temperature stirring, and stir evenly to obtain a reaction Type waterproof coating.

Abstract

The invention provides a reactive waterproof coating. A waterproof bridging agent is introduced in the invention. The waterproof coating formed by combining one end of the waterproof bridging agent with a C=C double bond, a carboxyl group -COOH and a hydroxyl group -OH in asphalt and combining the other end of the waterproof bridging agent with acid radicals generated after cement hydration comprises, by weight, 20-60 parts of rubber latex, 20-60 parts of emulsified asphalt and 0.3-4 parts of the waterproof bridging agent. When the waterproof bridging agent in the above product is in contact with a base surface, active groups in a molecule rapidly chemically reacts with the base surface to generate a chemical bonding effect and generate strong adhesion, other functional groups in the molecule are stretched in a rubber and asphalt composite layer and are tightly combined with the rubber and asphalt composite layer through steric hindrance and intermolecular active force, like a waterproof bridge is erected, and asphalt and rubber are combined to make a coating layer keep the adhesion of the asphalt and have the excellent elasticity, the weatherability and other performances of the rubber after curing. 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...
