Abstract

The invention discloses an automobile film and a preparation method thereof. The automobile film comprises an anti-ultraviolet layer, a first plastic film layer, a thermochromic heat-insulating compound layer, a second plastic film layer and an anti-scratching layer. The first plastic film layer is arranged in the anti-ultraviolet layer, the thermochromic heat-insulating compound layer is arrangedin the first plastic film layer and is formed by means of a nano heat-insulating liquid and a thermochromic agent, the second plastic film layer is arranged in the thermochromic heat-insulating compound layer and is opposite to the first plastic film layer, and the anti-scratching layer is arranged on the second plastic film layer and is opposite to the thermochromic heat-insulating compound layer. By arranging the thermochromic heat-insulating compound layer, the automobile film can change in color and change the absorptivity to infrared light along with change of temperature in a natural environment, so that the integral temperature of a car is improved effectively, and different visual comfort demands of drivers and passengers in a natural environment where the intensity of sunlight changes continuously are also met. According to the preparation method, the thermochromic agent and acrylic resin are melted better, so that a temperature-sensitive material meeting the manufacturing demands of the automobile film is obtained.

Description

technical field [0001] The invention relates to the technical field of car film, in particular to a car film with temperature-sensitive discoloration and a preparation method thereof. technical background [0002] At present, the heat insulation car film used on the car window is mainly formed by coating the heat insulation material on the PET substrate with acrylic resin as the carrier. This technology has gradually been accepted by car film manufacturers. Absorb infrared rays in visible light to achieve the purpose of heat insulation, and even add and adjust different pigments to meet customers' needs for color selection, and add temperature-sensing agents to make the car film adjust its response to infrared light accordingly as the temperature changes The absorptivity and different colors can effectively improve the overall temperature of the cabin and meet the different visual comfort needs of drivers and passengers in the natural environment where the intensity of sunli...
