Problems solved by technology

[0004] (1) Because of the organic binder, there is the release of formaldehyde, which is harmful to the human body;
[0005] (2) Not resistant to high temperature
At high temperature (such as fire, etc.), the organic binder will decompose and release toxic and harmful gases, and the material will loosen and fall off, which is not conducive to safe use;
[0006] (3) The structural strength of the material is low
If the density is greatly increased, the strength is improved, but the thermal conductivity is also increased, which reduces the thermal insulation effect

Description

technical field [0001] The invention relates to a basalt continuous fiber thermal insulation material and a preparation method thereof, in particular to a building wall thermal insulation material and a preparation method thereof, and belongs to the technical field of inorganic thermal insulation materials. Background technique [0002] Currently commonly used inorganic thermal insulation materials such as asbestos, glass wool, rock wool, aluminum silicate fiber and other fibrous materials are usually products made of phenolic resin or urea-formaldehyde resin through heat setting. [0003] Thermal insulation materials for buildings are generally divided into organic and inorganic thermal insulation materials. At present, due to the consideration of environmental protection and safety, organic thermal insulation materials are being gradually phased out, and inorganic thermal insulation materials are used. Among the commonly used inorganic thermal insulation materials such as...
