Abstract

The invention provides a light energy-saving and heat-insulating composite wallboard which is on the basis of organic / inorganic hybridized nano-enhanced modification technology and a preparation method thereof, and relates to a heat-insulating wallboard. According to the heat-insulating wallboard, a calcium silicate plate serves as a surface layer of the wallboard and ceramsite concrete serves as a core material. The ceramsite concrete is prepared from ceramsite, cement, coal ash, gypsum, AcryloPOSS, redispersible emulsion powder, cellulose, a water reducing agent, a foaming agent and an early strength agent. The strength, the durability, the flame resistance and the working performances of the light energy-saving and heat-insulating composite wallboard are improved by adding organic / inorganic hybridized nano particles into the ceramsite concrete and using the nano size enhancement effect and the flame resistance of the POSS, so the composite wallboard is energy-saving and environment-friendly, is easy to assemble and disassemble and can be hung through a nail.

Description

technical field [0001] The invention relates to a thermal insulation wallboard, in particular to a lightweight energy-saving thermal insulation composite wallboard based on organic / inorganic hybrid nano-reinforcement modification technology and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, population growth and the improvement of people's living standards, the scale of economic infrastructure has expanded, the construction has developed rapidly in the direction of diversification and technology, and building materials have also developed in the direction of environmental protection, energy saving, light weight and high strength. Clay bricks in traditional partition wall materials destroy fields and occupy land, seriously waste land resources, consume serious energy, and even pollute the environment. At the same time, the wet construction method used in them results in high labor intensity and high construction ...
