Nano-ceramic thermal insulation film and preparation method thereof

Abstract

The invention relates to a nanophase ceramics heat insulation film, comprising a heat insulation film main body, wherein the heat insulation film main body comprises at least two layers of composite films, one layer is a heat insulation layer which is a nanophase ceramics heat insulation layer made of nanophase ceramics materials, the outer side of the nanophase ceramics heat insulation layer is provided with a scratching resistance layer, and the scratching resistance layer is the outmost layer of the heat insulation film. The preparation method of the nanophase ceramics heat insulation film comprises the following steps: selecting base materials; evenly coating the heat insulation layer containing the nanophase ceramics particles on the base material; drying; coating one projection layer on one side of the heat insulation film main body, and arranging one layer of heating resistance layer on the other side; drying; coating the scratching resistance layer on the projection layer; coating a safe base layer on the heating resistance layer; drying; coating a gluing layer on the safe base layer in a pressure sensing mode; coating a releasing layer on the gluing layer; and drying. According to the nanophase ceramics heat insulation film, the strength and the service life of a carrier can be improved and prolonged.

Description

technical field [0001] The invention relates to a film, in particular to a heat insulating film. Background technique [0002] Heat insulation film is also called sunscreen heat insulation film. "Sunscreen" means that it can effectively block more than 90% of ultraviolet rays. Today's automotive aftermarket has gradually become a "golden industry", and the automotive sunscreen and heat insulation film market has already accounted for a considerable proportion in the automotive aftermarket. After all, sunscreen and heat insulation are needed in summer, and it is necessary to prevent ultraviolet radiation from harming the human body. It can also play a certain explosion-proof role to minimize accident hazards. With the increase of private car owners, the sunscreen and heat insulation film market is booming, and the industry is gradually developing. [0003] The existing heat insulation film is usually formed by bonding the heat insulation layer and the metal coating. The met...

AI Technical Summary

Problems solved by technology

[0003] The existing heat insulation film is usually formed by bonding the heat insulation layer and the metal coating. The metal coating of this heat insulation film is mostly made of plastic materials with metal plating on the surface, and the fire performance is not good enough. When exposed to air and sunlight, the metal coating is easily oxidized, and the service life is not long enough
