Light foamed ceramic wall building material with iron tailings as main raw material

Abstract

The invention relates to a light foamed ceramic wall building material with iron tailings as a main raw material and a production process thereof. The light foamed ceramic wall building material can be used for replacing traditional wall materials and thermal insulation materials. Iron tailings are adopted as the main raw material of the building material provided by the invention, quartz, calcite, sodium carbonate, borax, alumina and a foaming agent are configured, the ball milling time of raw materials in the production process is about 10h, the fineness is 300 meshes, a roller kiln is selected in the sintering process, the sintering period is about 6h, and the sintering temperature is about 1030 DEG C. The successful development of the building material of the invention is a technological revolution of building wall materials, which can greatly reduce the cost of building walls, reduce the labor intensity of workers, reduce the overall weight of buildings, reduce the basic load of the buildings, and meanwhile, achieving such targets of buildings as lightweight, thermal insulation, sound insulation, moisture resistance, and the like, and meeting the current environment-friendly, non-pollution and energy-saving requirements of modern buildings.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a foam ceramic lightweight wall building material with iron tailings as the main raw material. Background technique [0002] According to statistics from the Ministry of Housing and Urban-Rural Development, among the approximately 42 billion square meters of buildings in China, more than 95% of the building wall structure materials use traditional wall materials with high energy consumption and high thermal conductivity. An external thermal insulation layer must be added. At present, organic materials or inorganic composite materials are generally used for external wall insulation, and these materials generally have problems such as fire prevention, toxicity, durability, and waterproofing. For example, organic materials mainly include polystyrene boards, polyurethane boards, phenolic insulation boards, etc. These organic insulation materials belong to Class B, are not...

AI Technical Summary

Problems solved by technology

At present, organic materials or inorganic composite materials are generally used for external wall insulation, and these materials generally have problems such as fire prevention, toxicity, durability, and waterproofing.

For example, organic materials mainly include polystyrene boards, polyurethane boards, phenolic insulation boards, etc. These organic insulation materials belong to Class B, are not resistant to high temperatures, are easy to burn, and release a lot of heat when they burn, and produce a lot of toxic and harmful gases at the same time. Accelerate the spread of the fire, and easily cause casualties of trapped people and rescuers; inorganic composite materials mainly include rock wool board, glass wool board, etc. These inorganic composite insulation materials contain dust and fine fibers, which not only pollute the air but also easily breed bacteria. It has long been a hidden danger to people's health, and its durability and water resistance are not good.
