Description

Technical Field

[0002] Thermal insulation cotton is a material with highly efficient thermal insulation properties, widely used in construction, industry, transportation, and other fields. It is often made of ceramic fibers, glass fibers, aerogel fibers, etc., and reduces heat transfer through air barriers between fibers or special structures. In construction, it is used for exterior wall and roof insulation to reduce energy consumption; in industry, it is used to wrap kilns and pipes to improve energy efficiency; in transportation, it can provide thermal insulation and noise reduction, as seen in applications such as automobile engine compartments.

[0003] Existing thermal insulation cotton is relatively simple in structure and function. However, thermal insulation cotton is often used in various high-temperature environments, such as kilns and factories. In these high-temperature environments, not only is good thermal insulation performance required, but it also needs to have a certain flame-retardant effect. Otherwise, once the thermal insulation cotton is burned on a large scale, it will suffer significant losses. Therefore, it is necessary to design a flame-retardant thermal insulation cotton to solve this problem. Utility Model Content
