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 h...

Abstract

The present invention relates to the technical field of building thermal-insulation materials, particularly to a wall inorganic fiber thermal-insulation material preparation method, which comprises: placing various raw materials into a stirrer according to a certain weight part ratio, stirring to form a slurry, cooling, defoaming to obtain a slurry finished product, shaping the slurry finished product, and baking to form the thermal insulation material. A purpose of the present invention is to provide a preparation method of a wall inorganic fiber thermal-insulation material with characteristics of high strength, fire resistance, and fire retardation.
