Embodiment 1

[0031] In this embodiment, a thermal transfer film for a vehicle number plate with strong tolerance comprises a tape base and a lubricating layer and a thermal transfer layer arranged on both sides of the tape base, wherein the thermal transfer layer is from close to the tape base to far away from the tape The base is an inner coating, a cross-linked cured layer, a color layer, and a top coating in sequence; the lubricating layer can be prepared according to the prior art, specifically an acrylic modified silicone resin, wherein the silicone content is 20%, Purchased from (Wacker Chemicals (China) Co., Ltd.).

[0032] The inner coating is composed of the following raw materials in weight percentage: 18.75% of ethylene-hydroxyethyl acrylate copolymer, 75% of styrene-maleic anhydride copolymer, 2.5% of polytetrafluoroethylene wax micropowder, and 3.75% of BHT antioxidant.

[0033] The cross-linked cured layer is composed of the following raw materials in weight percentage: 44% o...

Embodiment 2

[0044] The difference between this example and Example 1 is that the total thickness of the thermal transfer film for the vehicle number plate in Example 2 is 28.2 μm, wherein the thickness of the tape base is 23 μm, the thickness of the lubricating layer is 0.2 μm, the inner coating is 2 μm, Cross-linked cured layer 1μm, color layer 1μm, top coat 1μm.

[0045] The preparation method of the thermal transfer film for the vehicle number plate provided in this embodiment is the same as that in Embodiment 1.

Embodiment 3

[0047] The difference between this example and Example 1 is that the total thickness of the thermal transfer film for the vehicle number plate in Example 3 is 28.1 μm, wherein the thickness of the tape base is 23 μm, the thickness of the lubricating layer is 0.1 μm, the inner coating is 1 μm, Cross-linked cured layer 2μm, color layer 1μm, top coat 1μm.

[0048] The preparation method is the same as in Example 1.

Abstract

The invention belongs to the technical field of hot stamping materials, and particularly relates to a high-tolerance heat transfer printing film for a vehicle license plate and a preparation method of the high-tolerance heat transfer printing film. The heat transfer printing film comprises a tape base, a lubricating layer and a heat transfer printing layer, the heat transfer printing layer sequentially comprises an inner coating, a cross-linking curing layer, a color layer and a top coating from the part close to the tape base to the part far away from the tape base; the inner coating comprises an ethylene-hydroxyethyl acrylate copolymer, a styrene-maleic anhydride copolymer, polytetrafluoroethylene wax micro powder and an antioxidant; the cross-linking curing layer comprises melamine formaldehyde resin, polyether polyol and silicon dioxide matting powder; the color layer comprises terpene phenolic resin, hydrogenated petroleum resin and carbon black; and the top coating comprises high chlorinated polyethylene resin, a styrene-butadiene-styrene block copolymer and asphalt. The heat transfer printing film is used for manufacturing the vehicle license plate, is firm and reliable, has excellent weather resistance and chemical resistance, and can be applied to various severe and complex construction environments.

Description

technical field [0001] The invention belongs to the technical field of hot stamping materials, and in particular relates to a thermal transfer film for vehicle number plates with strong tolerance and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the traditional manufacturing process of vehicle number plates has more and more disadvantages such as complex process, high labor intensity, and environmental pollution. With the development of thermal transfer printing technology, the application fields of labels are becoming more and more extensive. Many products made by traditional printing methods can now be realized by digital thermal transfer printing. Then, the production of vehicle number plates by thermal transfer printing can realize digital printing, which is environmentally friendly and efficient throughout the process, and saves materials. [0003] The traditional printing process is metal plate-print...
