Environment-friendly, heat-preserving and waterproof building composite board and preparation method thereof

Abstract

The invention discloses an environment-friendly, heat-preserving and waterproof building composite board and a preparation method thereof. The environment-friendly, heat-preserving and waterproof building composite board is prepared from the following raw materials in parts by weight: 30 to 50 parts of portland cement, 10 to 15 parts of fiber, 5 to 10 parts of montmorillonite powder, 8 to 15 parts of rutile titanium dioxide, 12 to 15 parts of organosilicone modified epoxy resin, 12 to 18 parts of gypsum, 15 to 25 parts of melamine, 4 to 9 parts of polyester fiber, 10 to 20 parts of a sodium silicate solution, 2 to 10 parts of polyacrylamide, 1 to 8 parts of tributyl phosphate, 11 to 17 parts of acrylate and 2 to 8 parts of lightweight aggregate. According to the invention, the preparation process is simple and has low cost; and the prepared environment-friendly, heat-preserving and waterproof building composite board has the advantages of light weight, good waterproof and heat-preserving effects, strong chemical stability, and no toxicity and odor, and is an ideal heat-preserving material.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to an environmentally friendly, heat-preserving and waterproof building composite board and a preparation method thereof.

AI Technical Summary

Problems solved by technology

EPS, XPS, and PU are all organic thermal insulation materials. The biggest advantage is light weight, heat preservation, and good heat insulation; the biggest defect is fire prevention, poor safety, easy aging, easy to burn, large smoke, high toxicity, and low load-bearing capacity when burning. , service life, and fire resistance are not as good as inorganic insulation materials
