Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the interface properties between the ion storage layer and the electrochromic layer are quite different, so it is difficult for the ions in the ion storage layer to move quickly into the electrochromic layer when power is applied, resulting in electrochromic The color change response time of the chromogenic layer is longer, which affects the color change efficiency of the electronically controlled dimming glass

preparation example 1

[0044] The raw materials used in this preparation example can be obtained from the market, wherein the lithium-based bentonite is selected from the lithium-based bentonite produced by Xinyang Wancheng New Materials Co., Ltd.; the lithium hydroxide is selected from the lithium hydroxide produced by Jining Sanshi Biotechnology Co., Ltd.; modified Lithium bentonite was prepared according to the following steps:

[0045] (1) Mix 40kg of lithium bentonite with 15kg of lithium hydroxide, and preheat at 180°C to obtain prefabricated lithium bentonite;

[0046] (2) The prefabricated lithium-based bentonite was calcined at 700° C. for 3 hours, and the calcined product was cooled and pulverized to an average particle size of 15 μm to obtain a modified lithium-based bentonite.

preparation example 2-4

[0048] As shown in Table 1, the difference between Preparation Example 2-4 and Preparation Example 1 is that the amount of lithium hydroxide added is different.

Abstract

The application relates to the technical field of glass products, and specifically discloses an intelligent dynamic dimming film and its preparation method and application. The intelligent dynamic dimming film is made of the following raw materials by weight: 50-70 parts of carrier resin, 20-30 parts of electrochromic filler, 20-30 parts of modified lithium-based bentonite, 12-20 parts of carbon nanotubes, coupling Dose 8‑16 parts. This application shortens the response time of the color change of the intelligent dynamic dimming film, and improves the color changing efficiency of the intelligent dynamic dimming film.

Description

technical field [0001] The present application relates to the technical field of glass products, and more particularly, to an intelligent dynamic dimming film and a preparation method and application thereof. Background technique [0002] Electrochromic glass is a new type of functional material. Transition metal oxides are usually added to electrochromic glass as electrochromic materials. Electrochromic materials can change color under the action of an applied voltage, so as to adjust the transmittance and absorbance. Adjustment, which can not only play the role of anti-peeping, but also improve the lighting effect, has been widely used in many fields such as information, electronics, energy, construction and national defense. [0003] The Chinese patent with the publication number CN105759530B discloses an electronically controlled dimming glass, which includes a first transparent glass substrate layer, a first transparent conductive layer, an ion storage layer, an ion con...
