Abstract

The invention relates to a polyester film, in particular to a high-transmittance high-definition anti-explosion polyester film and a preparation method thereof. In order to solve the problems of low light transmittance, poor anti-ultraviolet effect and high haze of the existing automobile window outer film, the invention provides the high-light-transmittance high-definition anti-explosion polyester film and the preparation method thereof. The polyester film sequentially comprises a coating layer, a first functional layer, a core layer, a second functional layer, a metal heat insulation layer,a bonding layer, a PET base film layer and an adhesive layer. The polyester film can be used as an automobile window film and is adhered to the outer surface of an automobile window.

Description

technical field [0001] The invention relates to a polyester film, in particular to a high-transmittance, high-definition, anti-explosion polyester film and a preparation method thereof. The polyester film can be used as an automobile window film and be pasted on the outside of the automobile window. Background technique [0002] The film on the car glass has multiple functions, the main function is to block ultraviolet rays, block part of the heat, prevent injuries caused by glass splashing, and prevent glare. Damage, through physical reflection, reduce the temperature inside the car and reduce the use of car air conditioners, thereby reducing fuel consumption and saving some expenses. The traditional film for the front of the car is a transparent film with a single function, low anti-ultraviolet effect, and poor heat insulation performance. The clarity of the film is not good enough, affecting the driver's vision. Contents of the invention [0003] In order to solve the ...
