A kind of using clay to prepare thermal insulation wall material and preparation method thereof

Abstract

The invention relates to the technical field of building thermal insulation materials, in particular to an anti-corrosion and waterproof coating for subway shield segments and a preparation method thereof; Agent, foaming agent, waterproofing agent and thickener are used as raw materials for preparing thermal insulation wall materials, and the prepared thermal insulation wall materials have heat resistance, good flame retardant effect, and have the advantages of small bulk density and good thermal insulation effect at the same time; The prepared thermal insulation wall material also has low temperature resistance, can be used normally under the condition of -30°C, and also has the advantages of good waterproof performance and strong wear resistance; Foaming is carried out during the material preparation, the preparation speed is improved, and waste is utilized at the same time, which is energy-saving and environmentally friendly; the present invention cooperates with the bamboo fiber, viscose fiber and glass fiber in the fiber combination, so that the strength and stiffness of the thermal insulation wall material are significantly improved improve.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a thermal insulation wall material prepared from clay and a preparation method thereof. Background technique [0002] Building energy consumption in developed countries abroad accounts for 30%-40% of the total energy consumption in society. Building energy conservation is the most potential and most direct and effective way among various ways of energy conservation. In building energy consumption, the energy consumption caused by external walls accounts for about 60% of the total building energy consumption, so wall insulation is the key to realizing building energy saving. [0003] At present, there are two main types of materials used for building exterior wall insulation in my country: (1) Organic insulation materials: polystyrene foam materials, foam rubber materials, polyurethane foam materials, etc.; (2) Inorganic insulation materials: rock wo...

Problems solved by technology

Among them, although organic insulation materials have good thermal insulation properties and small bulk density, they have poor heat resistance and are easy to burn, and they release a lot of heat and produce a lot of toxic fumes during combustion, which will not only accelerate the spread of the epidemic, but also easily cause casualties. With the emphasis on fire protection and the vigorous promotion and implementation of fire protection codes in the construction field, its scope of use will become smaller and smaller

Moreover, although the existing organic and inorganic thermal insulation materials have good heat resistance and flame retardant effect, they have large capacity and poor thermal insulation effect.
