Continuable-extrusion-molded and baking-free outer-wall self-heat-insulation hollow building block and preparation method thereof

Abstract

The invention relates to a continuable-extrusion-molded and baking-free outer-wall self-heat-insulation hollow building block and a preparation technology thereof. Specially, the baking-free outer-wall self heat-insulation hollow building block is obtained by using a geopolymer or a mixture of the geopolymer and cement as a bonding agent, a hollow glass micro bead or a mixture of the hollow glass micro bead and a glazed hollow bead as an ultralight filler, using one or more of furnace slag, coal cinder, mine tailings, and brick slag as a secondarily light filler for coordination, performing linear cutting molding under a plastic condition by adopting a continuous extrusion process or performing molding by adopting a pressing process, and performing maintenance. The continuable-extrusion-molded and baking-free outer-wall self heat-insulation hollow building block has the characteristics of high early strength, high strength and light mass, heat preservation and fire resistance, permeability resistance and sound-insulation performance, good interface bonding performance, a beautiful appearance and the like; and the preparation method just needs a simple extrusion molding process or a pressing molding process, and has the advantages that the production capacity is large, the operation is convenient, molds and storage yards are less, the manufacture costs are low and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a non-fired external wall self-insulating hollow block capable of continuous extrusion molding and a preparation method thereof. Background technique [0002] The issue of energy saving has been widely valued by countries all over the world. In my country's "Twelfth Five-Year Plan", energy conservation and environmental protection rank first among major industries; The top priority of the work, so energy-saving and environmentally friendly materials have a broad space for development. In terms of energy consumption, building energy consumption ranks first in all industries; in building energy consumption, the energy wasted through walls occupies a major position, so the development of wall insulation and energy-saving materials is of great significance to people's livelihood and social and economic development. At present, external wall insulation materials are divided...

Problems solved by technology

[0005] The main purpose of the present invention is to overcome the inability of the prior art to provide a self-insulating hollow hollow wall with simple and efficient preparation process, high strength, early strength and other mechanical properties, as well as self-insulation, fire resistance, sound absorption, impermeability and other functions. To overcome the shortcomings of blocks, provide a self-insulating hollow block for non-fired external walls that can be continuously extruded and formed, which is high-strength, light-weight, and has good thermal insulation, fire protection, sound insulation, and impermeability properties.
