Problems solved by technology

However, the thermal insulation building materials currently used are not ideal in various properties, especially in terms of thermal insulation, weather resistance, acid and alkali resistance, etc., which cannot meet people's needs.
Insulation materials in the prior art generally have hidden dangers such as large thermal conductivity, large specific gravity, easy to fall off, and poor moisture resistance, and the added ingredients and pungent odor of traditional insulation materials are likely to have adverse effects on human health and the environment

Abstract

The invention discloses a heat-insulation building environmental-protection composite material and a preparation method thereof. The composite material comprises 20-35 parts of diatomite, 20-30 parts of Portland cement, 15-30 parts of mixed resin, 10-20 parts of reinforced fibers, 8-15 parts of an inorganic filler, 20-35 parts of an antioxidant, 11-22 parts of protective colloid, 10-12 parts of a fire retardant, 10-15 parts of a foaming agent and 5-10 parts of a waterproof agent. The composite material improves the adhesion stress of a coating material and matrix resin, improves the processing technology of product coatings, improves the quality of building decoration products, prolongs the service life of the products, enhances the shock resistance and the cracking resistance of the products; and the preparation method has the advantages of simplicity, high yield, repeatable use of the material, greenness and environmental protection, energy saving and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of composite material production, in particular to a thermal insulation building environmental protection composite material and a preparation method thereof. Background technique [0002] The production cost of building composite materials in the prior art is high, the cost of raw materials is high, and the produced building composite materials do not have the performance of degradation and environmental protection, and the strength and toughness of the building composite materials in the prior art cannot meet the actual use time demand. [0003] The use of thermal insulation materials in buildings can not only save energy significantly, but also effectively improve living conditions. At present, the construction of thermal insulation materials in my country is still in the development stage, and the focus is on the thermal insulation in the cold northern regions and the thermal insulation in the southern ...
