Multifunctional composite building material and construction method thereof

Abstract

The invention relates to a multifunctional composite building material and a construction method therof. The functions of the material include heat preservation, cold preservation, heat interruption,water resistance, moisture prevention, fire prevention, peeling prevention, sound insulation, whitening prevention, air purification, sterilization, negative ion generation and the like. The inventionprovides the multifunctional composite building material. Nano-SiO2, nano-TiO2, nano-Al2O3, nano-ZnO and other nano-materials are mainly adopted. In addition, the material also adopts the following raw materials: nano-nickel-cobalt ferrite or nickel-zinc ferrite; surfactant; diethanolamine lauryl sulfonate or protein extract, pulp waste liquid, silica and other aerating agents; diamond health stone, hydroxyethyl cellulose (HEC) and other thickeners; and 3-butyl phosphate or butanol and other foam eliminate agents. The above raw materials are combined into the multifunctional composite building material according to a certain ratio. The invention also provides the construction method thereof. After the above multifunctional composite build material and a color carrier are mixed, the mixture is directly sprayed or applied to a concrete layer or a plastering layer inside and outside a building.

Description

Background technique [0001] At present, buildings such as residences, public houses, underground structures, refrigeration facilities, wall panel buildings, channel tunnels, tunnels, and road facilities are all undergoing some waterproof, moisture-proof, and thermal insulation after construction of concrete operations, wall laying, and building structures. Material or foam board, steel mesh construction or galvanized steel mesh construction, expansion and bolt fixing construction, second plastering, thin plastering, grinding, painting of interior and exterior wall paint, etc., require a lot of materials and labor , funding and project cycle. [0002] With the development of green environmental protection building technology and energy-saving technology and the provision of people's living standards, there is an increasing demand for zero-energy and zero-carbon buildings, especially for some processes such as thermal insulation, waterproof, moisture-proof and fireproof material...
