Solid waste regenerated foamed ceramic material for thermal insulation wall and preparation method

Abstract

The invention discloses a preparation method of a solid waste regenerated foamed ceramic material for a heat preservation and insulation wall. According to the preparation method, screening, refining, foaming and curing are performed on solid wastes such as industrial tailings and construction wastes to form fireproof foamed ceramic for heat preservation and insulation of a building wall. The method specifically comprises the following steps of: enabling the performance of the solid wastes to meet the requirements of a foamed ceramic raw material on fineness and purity through processes such as carbon removal and ball milling; mixing the solid wastes with a foaming agent and a curing agent, preparing the foamed ceramic through technological processes such as foaming, curing and hydration; and finally cutting and grading the foamed ceramic material with a low heat conductivity coefficient so as to apply the material to the thermal insulation wall. With the material adopted, not only can the problem of environmental pollution caused by solid wastes be solved, but also heat energy consumption of buildings can be reduced, and a good strategy is provided for turning waste into wealth.

Description

technical field [0001] The invention belongs to the technical field of preparation of thermal insulation materials, in particular to a method for preparing solid waste regenerated foam ceramic materials used for thermal insulation walls. Background technique [0002] With the rapid development of industrialization and urbanization, huge energy consumption and the generation of a large amount of solid waste come with it. Among the major solid wastes in my country, general industrial solid wastes generate the largest amount. In addition, the amount of construction waste in my country has accounted for 30% to 40% of the total amount of urban waste. Although there are many kinds of solid waste treatment methods at present, for example, sanitary landfill, incineration, composting and so on. However, these methods not only occupy a large amount of land and cost a lot of construction funds, but also cause serious environmental pollution problems caused by dust, dust and ash in th...

Problems solved by technology

At present, the utilization of solid waste is less, and the domestic utilization rate is less than 10%.

[0003] At present, there are huge safety hazards in the use of traditional organic thermal insulation materials (such as polystyrene foam, polyurethane foam, granular insulation materials)

Once a fire breaks out, the organic material will soften and deform above 100°C, which will cause the fire to spread rapidly and cause unpredictable losses and casualties

At the same time, after the organic board is ignited, the toxic and harmful gas produced volatilizes in the air. After the human body inhales it, it is easy to cause a variety of respiratory diseases and cause additional damage.

On the other hand, traditional inorganic thermal insulation materials (such as foam concrete, rock wool, and glass wool) will cause problems such as reduced structural durability and difficult construction due to their low mechanical strength, high water absorption, and poor construction operability.
