Low-water-absorption solid waste foam concrete with waterproof layer structure and preparation method thereof

Abstract

The invention generally relates to the technical field of waterproof coatings, in particular to low-water-absorption solid waste foam concrete with a waterproof layer structure, which comprises a solid waste foam concrete body (1) and the waterproof layer structure, wherein the waterproof layer structure comprises a polymer cement waterproof layer (2), a capillary crystalline waterproof layer (3),a polymer emulsion waterproof layer (4) formed by compounding neoprene latex and an ethylene-vinyl acetate copolymer, and a single-component water-based waterproof layer (5) which are sequentially arranged from the surface of the solid waste foam concrete body (1) to the outside. All the layers in the waterproof layer structure are sequentially formed on the surface of the solid waste foam concrete body in a coating mode, a waterproof and hydrophobic system is formed, and the water absorption rate of the solid waste foam concrete is remarkably reduced.

Description

technical field [0001] The invention generally relates to the technical field of waterproof coatings, in particular to a low water absorption solid waste foam concrete with a waterproof layer structure and a preparation method thereof. Background technique [0002] Solid waste foam concrete has the advantages of light weight, thermal insulation, flame retardancy and environmental protection, and has broad application prospects in thermal insulation and sound insulation. There are many factors that cause the high water absorption rate of solid waste foam concrete materials, such as the density, pore structure and permeability mechanism of solid waste foam concrete. Easy water absorption and low strength are the main reasons affecting the large-scale application of solid waste foam concrete. The solid waste foam concrete is easy to absorb water mainly because the capillary pores penetrate and absorb water and the internal interconnected pores penetrate and absorb water, resul...

Easy water absorption and low strength are the main reasons affecting the large-scale application of solid waste foam concrete

The solid waste foam concrete is easy to absorb water mainly because the capillary pores penetrate and absorb water and the internal interconnected pores penetrate and absorb water, resulting in high water absorption and poor waterproof performance of the solid waste foam concrete, which is prone to water seepage and leakage during practical application and construction.
