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 thermal coefficient is less than or equal to 0.2W / (m.K). The thermal insulation material can collect excess heat and release it in a timely and stable manner, with small gradient changes, which can effectively reduce the loss. The room temperature can be trended and the winter heat preservation can play a balancing role. With the development of the economy, thermal insulation materials have developed rapidly. Using good thermal insulation technology and materials in the fields of daily necessities, industry and construction can often achieve twice the result with half the effort. [0003] At present, low thermal conductivity insulation materials are developing in the direction of high effic...
