Safe and heat-insulating car roof cover film and preparation method thereof

Abstract

The invention provides a safe and heat-insulating car roof cover film and a preparation method thereof. The safe and heat-insulating car roof cover film provided by the invention is composed of a first release film layer, a scratch-resistant layer, a first base material layer, a first metal layer, a laminating adhesive layer, a second metal layer, a second base material layer, a mounting adhesivelayer and a second release film layer which are stacked in sequence. The preparation method of the safe and heat-insulating car roof cover film is simple in process, the preparation time is greatly shortened, the firmness of a metal material sputtered on the surface of a base material can be effectively controlled, and the appearance and the heat-insulating effect cannot be influenced by any stretching during preparation.

Description

technical field [0001] The invention relates to a heat-insulating film, in particular to a heat-insulating car roof coating film with high safety performance and a preparation method thereof. Background technique [0002] Conventional paint protection films, that is, films attached to car bodies, building surfaces, etc., can only provide basic protection. When the car is completely exposed to the sun, about 40% of the heat will be directly conducted into the car through the roof, and the remaining 60% of the heat will be directly conducted around the car, which will cause the temperature inside the car to be too high, and the air conditioner will consume less energy. It can be too large; and long-term ultraviolet radiation will also cause the fading of the car paint and accelerate the aging of the surface material. With the development of science and technology, the vast majority of cars on the market have sunroofs, and panoramic sunroofs are also becoming popular. Once the...

AI Technical Summary

Problems solved by technology

When the car is completely exposed to the sun, about 40% of the heat will be directly conducted into the car through the roof, and the remaining 60% of the heat will be directly conducted around the car, which will cause the temperature inside the car to be too high, and the air conditioner will consume less energy. can be too large; and long-term ultraviolet radiation will also cause the fading of the car paint and accelerate the aging of the surface material

With the development of science and technology, the vast majority of cars on the market have sunroofs, and panoramic sunroofs are also becoming popular. Once the glass sunroof is hit by gravel or high-altitude parabolic objects, it is easy to cause the glass to shatter and splash and hurt the people in the car, causing safety hazards. Hidden danger

[0003] At present, traditional car coating films have disadvantages such as poor heat insulation performance, weak radiation protection ability, and poor toughness, and car roof coating films that integrate safety and heat insulation functions are rare

At present, the car coating film on the market is made of PVC (polyvinyl chloride), TPU (thermoplastic polyurethane elastomer rubber, such as polybutylene terephthalate) as the base material, which can only be applied to the surface of the car body or building. Plays a basic protective role, can not effectively reflect ultraviolet and infrared rays, does not fit well on the roof surface with large curvature, low safety performance, unsatisfactory heat insulation effect, short service life, and there are restrictions on product promotion

[0004] In addition, in the production of car coating film, the process is quite long and generally takes several hours
