Environment protection and energy-saving novel heat insulation building material and preparation method thereof

Abstract

The invention discloses an environment protection and energy-saving novel heat insulation building material, which is prepared from, by weight, 80-90 parts of Portland cement, 8-10 parts of sulphate aluminium cement, 14-18 parts of fly ash, 8-10 parts of silicon ash, 2-4 parts of anti-crack enhancer, 1-2 parts of curing agent, 2-4 parts of fiber, 1-3 parts of calcium stearate, 0.1 part of foam stabilizer, 62-65 parts of water, 8-10 parts of hydrogen peroxide. The building material is green and environment-friendly, fireproof and high temperature resistant; the fireproof temperature is up to over 1000 DEG C; the combustion performance is grade A; through the test verification, the heat conductivity is about 0.05 W / (m.K), and the material is light in weight and low in density and water absorption rate; the density is 130-150 kg / m3; the waterproof property is good; the building material can be widely applied to a building wall slab, and especially applicable to the wall slab of an air control heat insulation warehouse. Meanwhile, the building material is simple in technique and high in production efficiency; the cost can be reduced to about 130 Yuan / m3; thus the building material is good for popularization and use on a large scale.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and in particular relates to an environmentally friendly and energy-saving new thermal insulation building material and a preparation method thereof. Background technique

[0002] Foamed cement is to fully foam the required formula raw materials mechanically through chemical principles, and mix the foam and cement slurry evenly, and then carry out cast-in-place construction or mold molding through the chemical reaction between raw materials, and is formed by natural curing. A new type of lightweight insulation material containing a large number of closed pores. It belongs to the bubble-like thermal insulation material, and its outstanding feature is that it forms closed foam pores inside the concrete, which makes the concrete lightweight and thermally insulated.

[0003] This year, with the extensive implementation of the national energy-saving policy, the industrial development of fo...
