Description

technical field [0001] The invention relates to the technical field of heat insulation materials, in particular to a high temperature resistant heat insulation material and a preparation method thereof. Background technique [0002] my country's economy is developing rapidly, but the development of energy production is relatively lagging behind. One of the best ways to solve the energy shortage is to save energy, that is, to reduce heat loss, improve the utilization efficiency of heat energy, and reduce energy waste. One of the most important measures for energy saving is the development and application of thermal insulation materials. The use of thermal insulation materials can effectively reduce heat loss, save fuel, and at the same time improve the working environment, ensure safe production, and improve work efficiency. After selecting the appropriate heat insulation material for heat insulation, the heat loss is greatly reduced, so the performance of the heat insulatio...
