Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] refer to figure 1 , the first embodiment of the present invention is a heat insulation film, which has a layered structure. The film structure of the heat insulation film is composed of multiple layers of heat insulation units, and the heat insulation units of each layer are arranged in the same direction; Each layer of thermal insulation unit is composed of a base material layer 101 and an airgel layer 102; the base material layer 101 is a polyimide or carbon fiber membrane, and the airgel layer 102 is a porous silica airgel; and, There is also a high temperature adhesive layer 103 between adjacent heat insulation units. The porous silicon dioxide airgel layer is composed of porous silicon dioxide airgel particles, and the porous silicon dioxide airgel particles are nanoscale particles. An aluminized layer 104 is also provided outside the outermost ...

Abstract

The invention relates to heat insulation materials, in particular to a heat-insulation film and a preparation method thereof. The heat-insulation film is in a layered structure, a film system structure of the heat-insulation film is formed by multiple layers of heat-insulation units in a compounding way, and each layer of heat insulation unit is arranged in the same direction; each layer of heat insulation unit comprises a substrate layer and an aerogel layer; the substrate layer is a polyimide or carbon fiber film, and the aerogel layer is porous silica dixide aerogel; and in addition, a high-temperature glue layer is also arranged between every two adjacent heat insulation units. The preparation method of the heat insulation film comprises the following steps: firstly, providing substrates; secondly, coating the aerogel on the single face of each substrate; thirdly, drying a semifinished product prepared in the step two into a heat-insulation unit; and fourthly, compounding multiplelayers of the heat insulation units. The invention provides the heat-insulation film which has small volume, convenient use and no environmental pollution as well as the preparation method thereof.

Description

technical field [0001] The invention relates to heat insulating materials, in particular to a heat insulating film and a preparation method thereof. Background technique [0002] Thermal insulation materials are widely used in production and living fields. The consequences of thermal energy leakage caused by poor insulation are not only the loss of thermal energy, but also thermal pollution. [0003] For the occasions where heat insulation is required for media above 300 degrees Celsius, such as the heat insulation of high-temperature steam pipelines, the existing heat insulation materials mostly use asbestos materials, and some asbestos is covered with a layer of aluminum platinum to increase the heat insulation effect. [0004] The existing asbestos heat insulating material is bulky and inconvenient to use; because asbestos is harmful to the human body, asbestos is easy to splash into the space and cause environmental pollution. Contents of the invention [0005] The o...
