Abstract

The invention belongs to the field of membrane technology and particularly relates to a car explosion-proof membrane and a preparation method thereof. The car explosion-proof membrane comprises a PET (polyethylene glycol terephthalate) carrier layer, wherein the front side of the PET carrier layer is provided with a hardening wear-resisting layer formed by coating a hardening wear-resistant paint; the back side of the PET carrier layer is provided with a heatproof light change layer formed by coating a heatproof light change paint; the outer surfaces of the hardening wear-resisting layer and the heatproof light change layer are respectively compounded with a protective membrane. The car explosion-proof membrane can be used as the vehicle window membrane and the glass outdoor membrane; besides the car explosion-proof membrane is high in transparency, excellent in weather resistance and ultraviolet-proof and thermal-insulation effects, and high in surface hardness, and the internal lights can be adjusted according to the external light source.

Description

technical field [0001] The invention belongs to the technical field of membranes, in particular to an automobile explosion-proof membrane and a preparation method thereof. Background technique [0002] Car explosion-proof membrane (Car explosion-proof membrane) means that the base material used is clear enough, even if the film is darker in color, the scenery seen must be thorough, not dim or deformed; the durability of the color of the car explosion-proof membrane. Problems existing in the current product: poor transparency, poor weather resistance, insufficient UV protection, poor heat insulation effect, inability to adjust the internal light according to the strength of the external light source, low surface hardness and wear resistance, etc. Contents of the invention [0003] The invention provides an automobile explosion-proof film with high transparency, good weather resistance, good ultraviolet protection and heat insulation effect, which can adjust internal light a...
