Abstract

The invention discloses a cement-base elastic waterproof composite material which has the advantages of simple construction, low cost and no poison and pollution and comprises a powder material and a liquid material, wherein the weight ratio of the powder material to the liquid material is 2:1. The cement-base elastic waterproof composite material has the advantages that the cement-base elastic waterproof composite material is a two-component novel waterproof material prepared by compounding synthetic high-molecular polymer emulsion and an inorganic powder material, and the defects of dry shrinkage and deformation of cement are improved by utilizing the good elasticity of polymers; the waterproof material has not only the elasticity and the flexibility of organic materials, but also the good durability of inorganic materials, so that after the waterproof material is coated and cured, a continuous structural film is formed by polymer emulsion and connected into a solid integrality with set cement produced by hydrating the cement so as to ensure that the coating film has certain elasticity, flexibility, extensibility, tensile strength and durability; and the cement-base elastic waterproof composite material can be premixed in a plant, and after the two components are mixed and stirred into slurry on spot, the cement-base elastic waterproof composite material is coated on the surface of a concrete structure.

Description
