Problems solved by technology

There are generally three types of traditional thermal insulation materials: rock wool thermal insulation material (the main component is rock wool), ceramic fiber thermal insulation material (the main component is ceramic fiber) and organic thermal insulation material. However, the above three thermal insulation materials have the following deficiencies: ( 1) Due to the easy water absorption of rock wool itself, the finished rock wool insulation material is easy to absorb water, and the thermal conductivity of water is high, and the heat preservation effect is poor. Therefore, the rock wool insulation material will make its heat preservation effect worse after absorbing water; Moreover, the weight of the rock wool insulation material after absorbing water will increase (the weight of the absorbed water itself). As the use time increases, the rock wool insulation material will become heavier and heavier due to excessive water absorption, and will fall off due to its own weight. , once the rock wool insulation material falls off, it cannot play the role of insulation

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a preparation method of inorganic fiber thermal insulation materials for walls. Background technique [0002] Insulation material is a material with low thermal conductivity, and its good insulation effect makes it widely used in daily life. There are generally three types of traditional thermal insulation materials: rock wool thermal insulation material (the main component is rock wool), ceramic fiber thermal insulation material (the main component is ceramic fiber) and organic thermal insulation material. However, the above three thermal insulation materials have the following deficiencies: ( 1) Due to the easy water absorption of rock wool itself, the finished rock wool insulation material is easy to absorb water, and the thermal conductivity of water is high, and the heat preservation effect is poor. Therefore, the rock wool insulation material w...
