Thermal-insulation waterproof car window film

Abstract

The invention discloses a thermal-insulation waterproof car window film. The thermal-insulation waterproof car window film comprises a transparent substrate layer, and a metal thermal insulation layerand a waterproof layer which are successively arranged on the transparent substrate layer, wherein the metal thermal insulation layer is formed by continuously depositing a plurality of layers of metal films by virtue of a sputter coating method; and a water contact angle of the waterproof layer is selected in a range of 90 to 150 degrees. The car window film of the invention is provided with themetal thermal insulation layer, so that about 70 percent of infrared heat can be reflected, less light can enter a car, the temperature in the car does not increases greatly, the thermal insulation effect is remarkable, no secondary radiation problem exists, the comfort of the car can be improved, and the oil consumption can be reduced. The car window frame is provided with the waterproof layer,the water contact angle on the surface of the waterproof layer is large, water drops are easy to form and fall to the bottom from the top of the surface and do not remain on a car window, so that a natural waterproof purpose can be achieved, and the safety of the vehicle when driving in raining can be improved.

Description

Technical field [0001] The present invention relates to the technical field of automotive film, in particular to a heat-insulating and waterproof car window film. Background technique [0002] As China's reform and opening up have increased and deepened, the economy has also increased year by year. Corresponding people's living standards and consumption levels have also been improved simultaneously. The car has gradually become a necessity for ordinary families to travel and travel from the previous high-end consumer goods, and it is also a manifestation of people's high-quality life. [0003] When a car is driving in rainy weather, the window glass is easily affected by rain, which affects the driver's correct judgment on the road conditions during driving, thereby causing traffic accidents and even casualties. The front window glass can be solved by windshield wipers, but the left and right front glass windows are not wiped. The water film formed on the glass refracts, making y...

AI Technical Summary

Problems solved by technology

[0003] When the car is driving in rainy days, the window glass is easily affected by the rain, which affects the driver's correct judgment on the road conditions during driving, which leads to traffic accidents and even casualties

The front window glass can be solved by wipers, but there is no wiper on the left and right front glass. The water film formed on the glass will make you unable to see the rear and side clearly. The water splash from the car makes everything outside the car blurred. Just when you are hesitating, a terrible traffic accident may happen

[0004] On the other hand, when we drive a car in hot weather, the heat from the outside always penetrates through the glass and enters the car. Even though the air conditioner is turned on to the maximum in the car, when the sun shines on us, we still don’t feel cool enough. Affects the comfort of driving, and the fuel consumption of the car is also high
