Composite nano heat insulation material

Abstract

The invention discloses a composite nano heat insulation material which is prepared from the following raw materials: a nano material, ceramic fibers, silicon dioxide, an antioxidant, a defoaming agent, a modifier, a solvent, aerogel, a finished nano microporous material and a finished nano heat insulation coating. The three-layer heat insulation performance is achieved by preparing a film layer of an original nano heat insulation material, cutting a finished nano microporous material into a material with the same thickness as a film layer obtained after film pressing, placing the film layer and the finished nano microporous material in a crossed mode, conducting compounding and then spraying a finished nano heat insulation coating. The finished nano heat insulation coating, the finished nano microporous material and the original nano heat insulation material are combined into a new heat insulation material, so that the heat insulation performance of the material can be greatly improved, and long-time heat insulation can be realized to the greatest extent when the material is used in a nano carbon industrial digital drying system. Therefore, the heat loss during operation of the system is reduced, and the cost required by operation of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a composite nanometer heat insulation material. Background technique [0002] Composite material is a new material formed by optimizing the combination of material components with different properties by using advanced material preparation technology. Composite materials generally defined must meet the following conditions. Composite materials must be man-made and designed and manufactured by people according to needs. Composite materials must be composed of two or more materials with different chemical and physical properties. Form, proportion, and distribution are combined, and there are obvious interfaces between the components. It has structural designability and can be used for composite structure design. Composite materials not only maintain the advantages of the material properties of each component, but also pass through each component. Complementarity and co...
