Embodiment 1
[0027] The photosensitive color-changing thermal transfer film for vehicles provided in this embodiment is composed of a carrier tape base and a thermal transfer color layer coated on one side of the tape base. The tape base is a 12 μm thick PET polyester film; The thermal transfer color layer is made of the following raw materials in parts by weight: 80 parts of silicone-modified acrylic resin; 20 parts of photochromic powder.
[0028] The specific preparation process of the photosensitive color-changing thermal transfer film for vehicles is as follows:
[0029] (1) Based on the weight ratio of silicone-modified acrylic resin: methylcyclopentane=3:5, after weighing in proportion, add silicone-modified acrylic resin to methylcyclopentane and heat to 60°C , stir until completely transparent, then add corresponding proportion of photochromic powder and disperse evenly, then grind the dispersed material with a pin-type sand mill until the D50 is less than 1.5 μm, after grinding, ...
Embodiment 2
[0059] The photochromic thermal transfer film product for vehicles provided in this example has a ratio of raw materials: 80 parts of silicone-modified acrylic resin; 20 parts of photochromic powder.
[0060] The preparation method of the photochromic thermal transfer film for vehicles provided in this example is substantially the same as the preparation method in Example 1, and only some parameters are adjusted as follows:
[0061] In the preparation process, in step (1), in terms of weight ratio, silicone modified acrylic resin: methylcyclopentane = 2:6; in step (2), the coating thickness is 5 microns; in step (3), drying The temperature is 100°C.
[0062] Product related performance testing:
[0063] (a) Appearance inspection after use: at a temperature of 160°C, the product made in this example is transferred to the tempered glass for vehicles. After the transfer, the surface layer is uniform without leaks and is transparent, which basically does not affect the light tran...
Embodiment 3
[0070] The photochromic thermal transfer film product for vehicles provided in this example has a ratio of raw materials: 80 parts of silicone-modified acrylic resin; 20 parts of photochromic powder.
[0071] The preparation method of the photochromic thermal transfer film for vehicles provided in this example is substantially the same as the preparation method in Example 1, and only some parameters are adjusted as follows:
[0072] During the preparation process, in step (1), in terms of weight ratio, silicone-modified acrylic resin:methylcyclopentane=1:7, and the heating temperature is adjusted to 70°C; in step (2), the coating thickness is 5 microns; The drying temperature in step (3) is 100°C.
[0073] Product related performance testing:
[0074] (a) Appearance inspection after use: at a temperature of 160°C, the product made in this example is transferred to the tempered glass for vehicles. After the transfer, the surface layer is uniform without leaks and is transparen...
