Problems solved by technology

[0002] The most widely used waterproof coatings in the prior art are polyurethane waterproof coatings, which are cheap and have a strong and pungent smell. The main function is benzene compounds. Thinner or gasoline can be diluted for construction. Since thinner is more advantageous in price compared with gasoline, 95% of engineering teams will use thinner to dilute traditional polyurethane waterproof coatings. The main component of thinner is organic solvents containing benzene , and benzene is recognized as a strong carcinogen, using this material for construction waterproofing can only temporarily solve the problem of leakage in a short period of time

Abstract

The invention provides an environment-friendly abrasion-resistant waterproof leakage repair material and a preparation method thereof.The environment-friendly abrasion-resistant waterproof leakage repair material is prepared from hydroxyl waterborne polyurethane containing isocyanate, calcium carbonate powder, powdery inorganic pigment, a defoaming agent and a colorless transparent waterborne polyurethane cross-linking agent, and the material comprises, by weight, 100 parts of hydroxyl waterborne polyurethane, 35-45 parts of calcium carbonate powder and 20-30 parts of the waterborne polyurethane cross-linking agent.The hydroxyl waterborne polyurethane, the calcium carbonate powder, the powdery inorganic pigment and the defoaming agent form a first component, and the waterborne polyurethane cross-linking agent forms a second component.When the material is used, the two components are mixed so that the environment-friendly abrasion-resistant waterproof leakage repair material can be obtained.the material is free of toxin, environment friendly and stable in performance, and is elastic, high in bonding force and resistant to acid, alkaline and aging after being cured into a film, the service life can be 30 years or above, and the defects that an existing conventional waterproof anti-seeping grouting material is not durable and not environmentally friendly enough can be overcome and made up for.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to an environmentally friendly wear-resistant waterproof leak-trapping material and a preparation method thereof. Background technique [0002] The most widely used waterproof coatings in the prior art are polyurethane waterproof coatings, which are cheap and have a strong and pungent smell. The main function is benzene compounds. Thinner or gasoline can be diluted for construction. Since thinner is more advantageous in price compared with gasoline, 95% of engineering teams will use thinner to dilute traditional polyurethane waterproof coatings. The main component of thinner is organic solvents containing benzene , and benzene is recognized as a strong carcinogen, using this material for construction and waterproofing can only temporarily solve the problem of leakage in a short period of time.
