Abstract

The invention discloses a novel-electrochromism-device-based automobile window with the high sun blocking performance and a manufacturing method thereof. According to the automobile window and the manufacturing method, the structure and the manufacturing technology of the electrochromism device are both improved, the electrochromism device has the self energy supplying characteristic accordingly, and therefore the novel service-life-prolonged automobile window which is high in sun blocking performance, free of a film pasting procedure and good in freezing resistance is manufactured; in addition, the method is simple and easy to operate, and industrial production is facilitated.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to a high sun-proof automobile window based on an electrochromic device and a manufacturing method thereof. Background technique [0002] In conventional technology, car windows are generally pasted with sunscreen film. Generally, the sunscreen film is made of PET (polyethylene) substrate. The higher-level sunscreen film uses multi-layer metal sputtering technology, vacuum technology and ion technology, as well as thin film physics and fine chemical technology. It has extremely high heat insulation efficiency, high tension, high elongation, and strong acid and alkali resistance. [0003] However, there are disadvantages such as high cost, need to increase the film application process, difficult installation, and easy aging when affixing a sunscreen film to the car window. Contents of the invention [0004] Aiming at the problems existing in the background technology, th...
