Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for furnaces, and in particular relates to a thermal insulation material and a preparation method thereof. Background technique [0002] With the gradual improvement of people's awareness of environmental protection, resource conservation, and energy utilization, how to reduce the high energy consumption of industrial industries has become the focus of attention. Insulation materials play a vital role in the energy saving and consumption reduction of industrial kilns and high temperature furnaces during use. [0003] At present, for industrial furnaces under various high-temperature conditions, some use light-weight insulation bricks alone as insulation materials, some use refractory fibers alone as insulation materials, and most of them are used in combination. [0004] For lightweight insulation bricks, whether it is by introducing lightweight aggregate or fiber, vermiculit...
