Embodiment 1

[0050] refer to figure 1 , the manufacture method of photochromic film for automobile comprises steps:

[0051] S1: Obtain pattern requirements including shape information of the pattern requested by consumers.

[0052] In this embodiment, the pattern requirement includes shape information of the pattern, color information of the pattern and size information of the pattern. The shape information represents the shape of the pattern, that is, the overall outline of the pattern, the color information of the pattern represents the color of the pattern, and the size information represents the size of the pattern.

[0053]Specifically, the shape and outline of the pattern can be obtained through the high-definition two-dimensional image of the pattern provided by the consumer, and the color information and size information can be obtained through the specified color and specified size proposed by the consumer. For example, the consumer provides a two-dimensional image of the "Merc...

Embodiment 2

[0082] refer to figure 2 , this embodiment is different from the steps of embodiment 1 in that:

[0083] S2: After the step of "making a mold consistent with the shape of the pattern required by the consumer according to the pattern requirement", it includes steps:

[0084] S3-1: Press the mold into the lighting surface of the photochromic film;

[0085] In this embodiment, the active force of the hydraulic cylinder to the mold should be properly adjusted to be small, so as to prevent the mold from being difficult to remove after being pressed into the photochromic film.

[0086] S3-2: removing the mold from the surface of the photochromic film;

[0087] In this embodiment, after the photochromic film is taken off, a groove whose contour is consistent with the mold is formed at the press-in place of the mold.

[0088] S23-3: Injecting a gel agent in the same color as the photochromic film in the press setting of the mold.

[0089] In this embodiment, the gel agent is inje...

Abstract

The invention discloses a photochromic film for an automobile and a manufacturing method thereof. The method comprises the following steps: that pattern requirements including shape information of patterns required to be displayed by consumers and the like are obtained; according to the pattern requirements, a mold consistent with the pattern required to be displayed by a consumer in shape is manufactured; the mold is embedded into the lighting surface of the photochromic film with the same color as the mold in a punch forming mode. The photochromic film has the effect that the pattern required by the consumer can be displayed after the photochromic film is irradiated by ultraviolet rays or sunlight.

Description

technical field [0001] The application relates to the technical field of color-changing materials, in particular to a photochromic film for automobiles and a manufacturing method thereof. Background technique [0002] Photochromic film is a material with the characteristics of discoloration, high thermal insulation rate, high transmittance and UV protection. [0003] Photochromism refers to the change of molecular structure of certain compounds under the action of light of a certain wavelength and intensity, resulting in a corresponding change in its absorption peak of light, that is, color; and this change is generally reversible. [0004] In conventional physical properties, the photochromic film absorbs ultraviolet rays or sunlight, and produces a color change. When the ultraviolet rays or sunlight are lost, it returns to the original color according to the indoor and outdoor temperature. [0005] Regarding the photochromic film, the market generally uses it as a film fo...
