Description

Technical field [0001] The invention relates to a low thermal conductivity thermal insulation material, a preparation method and application thereof, and belongs to the field of thermal insulation materials. Background technique [0002] Insulation materials are generally materials whose guiding thermal coefficient is less than or equal to 0.2W / (m.K). Insulation materials can collect excess heat and release them steadily in a timely manner. The gradient changes are small, which can effectively reduce the loss. The room temperature can be tempered and the winter insulation can play a balance. With the development of the economy, insulation materials have developed rapidly. The use of good insulation technology and materials in the fields of daily necessities, industry and construction can often achieve a multiplier effect with half the effort. [0003] At present, low thermal insulation materials are moving towards the integration of high efficiency, energy saving, thin layer, heat...
