EFFICIENT AQUEOUS NANO-SILICON RUBBER SEALING AND WATERPROOFING AGENT

An efficient aqueous nano-silicon rubber sealing and waterproofing agent, containing the following components in parts by weight: 10-90 parts of a nano-silica gel, 10-100 parts of nano diatomaceous earth, 5-150 parts of a nano polyurethane, 15-200 parts of a dry nano inorganic powder, 10-100 parts of nano methyl cellulose, 10-150 parts of a chelating agent, 15-200 parts of an expanding agent, 10-250 parts of a strengthening agent, 5-100 parts of an anti-freezing agent, 2-150 parts of a heat-resistant agent and 10-100 parts of an acid and alkali-resistant agent. The sealing and waterproofing agent has good waterproofness, permeability, film-forming property, elasticity, adhesion, water resistance and heat and humidity resistance, is suitable for being used in underground projects and waterproofing, anti-seepage and leakage repair projects such as roofing, and is also a good vapour barrier material in cold storage.
