Problems solved by technology

However, due to the disadvantages of airgel ultra-thin fiber reinforcement, such as easy to drop powder, easy to generate dust when shearing, and difficult to control the thickness, it needs to be packaged before use, which adds a packaging process and increases the product quality. The overall cost, so that the price remains high, which limits its large-scale application

Abstract

The invention relates to the technical field of an electronic product, in particular to an aerogel flexible film and a preparation method thereof. The aerogel flexible film is prepared from the following raw materials in parts by weight: 45 to 55 parts of flexible film forming agents, 23 to 165 parts of aerogel slurry, 3 to 5 parts of anti-foaming agents, 5 to 10 parts of fire retardants, 3 to 8 parts of flatting agents and 10 to 20 parts of water. The preparation method comprises the following steps of S1, film coating raw material preparation; S2, film forming; S3, demolding. The aerogel flexible film and the preparation method have the advantages that the aerogel flexible film has the characteristics of low heat conduction coefficient, flame retardant performance, controllable thickness, no dust, good toughness, bending and folding performance, environmental-friendly performance, free cutting and the like, and can be used in the fields of portable electronic products, household appliances, wearable equipment, power batteries and the like with high environmental-friendly requirements and limited heat isolation space; the maximum heat isolation help is provided for the electronicproduct heat management; the preparation method is simple and practical.

Description

technical field [0001] The invention discloses an airgel flexible film that can be used in the fields of 3C electronic products, household appliances, daily necessities, wearable devices, power batteries and the like and a preparation method thereof. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, consumer electronic products continue to develop in the direction of thinner and smarter, which brings higher challenges to the thermal management of electronic products. Insulation, new high-efficiency thermal insulation materials will play an increasingly important role. . Airgel is considered to be one of the top ten new materials with the greatest potential in the future. It is currently the lightest solid material in the world, and has the characteristics of high specific surface area, high porosity, low density and low thermal conductivity. At present, airgel ultra-thin fiber reinforcement ...
