Fabricated building thermal insulation wallboard and preparation method thereof

Abstract

The invention discloses a fabricated building thermal insulation wallboard which comprises the following raw materials in parts by weight: 70-90 parts of cement, 50-70 parts of high-calcium fly ash, 30-50 parts of quartz sand powder, 10-20 parts of polyacrylate emulsion, 6-10 parts of iris ensata thunb root internal fibers, 5-10 parts of polyvinyl acetate emulsion, 5-10 parts of sodium polyacrylate, 10-20 parts of magnesium aluminum silicate, 8-16 parts of oxidized polyethylene wax, 2-5 parts of potassium methyl silicate, 2-5 parts of divinyl benzene, 10-20 parts of activated carbon powder, 6-12 parts of silicon dioxide, 8-15 parts of ornithogalum caudatum bulb extracting solution, 2-4 parts of nonylphenol polyoxyethylene ether and 8-12 parts of water reducing agent. The invention furtherdiscloses a preparation method of the fabricated building thermal insulation wallboard. The thermal insulation wallboard material prepared by the method is high in strength, low in heat conductivity coefficient, low in volume water absorption and not easy to damp.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a prefabricated building thermal insulation wallboard and a preparation method thereof. Background technique [0002] Energy conservation and emission reduction is an inevitable requirement for promoting economic structural adjustment, transforming development mode, and realizing sustainable economic and social development. Prefabricated buildings are a new way to develop energy conservation and emission reduction, reduce energy consumption, and promote the sustainable development of my country's economy. The prefabricated building is a building assembled on the construction site with prefabricated workpieces. Since the prefabricated parts are made in advance according to the market and user needs, it has the advantages of fast construction speed, low cost, less affected by climate and weather, saving labor and reducing construction costs. The workload and complexity ...

AI Technical Summary

Problems solved by technology

[0003] Ordinary buildings are insulated through concrete walls and insulation layers, thereby reducing indoor and outdoor temperature exchange. In order to achieve thermal insulation effects in prefabricated buildings, special insulation wall panels are required for insulation. Ordinary insulation wall panels have poor waterproof and moisture-proof performance and are prone to moisture and mildew change, resulting in short service life of thermal insulation wall panels, and it is easy to cause adverse effects on the living environment
