Description

technical field [0001] The invention belongs to the technical field of thermal insulation material processing, and in particular relates to a preparation method of a liquid paste thermal insulation material. Background technique [0002] Insulation refers to a technological measure to reduce the heat transfer from the internal heat source of the object to the outside of the object. In order to achieve the purpose of heat preservation, it is necessary to adopt some materials and structures with specific and special properties. These materials are called insulation materials. Insulation materials have the following functions: (1) prevent burns; (2) save energy; (3) ensure process; (4) improve the environment; (5) protect equipment; (6) sound absorption and sound insulation. Therefore, it is widely used. [0003] At present, although there are cases in the industry where multiple functional raw materials are used in combination to prepare thermal insulation materials, most of ...
