Embodiment 1
[0020] like figure 1 As shown, the present invention provides an ultra-high temperature wear-resistant thermal transfer label, comprising a polyimide substrate 1, and a layer of wear-resistant thermal transfer coating layer 2 is arranged on the upper side of the polyimide substrate 1, A layer of release paper or a release film 4 is arranged on the lower side of the polyimide substrate 1, and a layer of adhesive layer is arranged between the polyimide substrate 1 and the release paper or release film 4 3.
[0021] Further, the polyimide substrate 1 has a thickness of 10-100U.
[0022] Further, the wear-resistant thermal transfer coating layer 2 is composed of epoxy resin, titanium dioxide and additives, and the parts by weight of each substance are:
[0023] 100 parts epoxy resin
[0024] Titanium dioxide 50~500 parts
[0025] Auxiliary 5~20 parts
[0026] Further, the auxiliary agent is selected from one of leveling agent, anti-settling agent, matting agent, wetting agent...

The invention discloses a superhigh-temperature wear-resistant heat transfer label which comprises a polyimide substrate, wherein a wear-resistant heat transfer coating layer is arranged on the upper side surface of the polyimide substrate, a layer of release paper or release film is arranged on the lower side surface of the polyimide substrate, and an adhesive layer is arranged between the polyimide substrate and the release paper or the release film. The invention also provides a preparation method of the superhigh-temperature wear-resistant heat transfer label. Characters or graphs can be printed on the surface of the superhigh-temperature coating layer by virtue of a heat transfer printing method, are distinct and discernible under a superhigh-temperature condition and are stong in wear resistance. A superhigh-temperature adhesive provided by the invention has good adhesion on the surfaces of various materials, is high in adhesion at a room temperature, and can still keep high adhesion at a superhigh temperature, so that the phenomenon of label falling and tilting caused by the high temperature can be avoided.
Description
technical field [0001] The invention relates to the field of chemistry, in particular to adhesives and label processing technology, in particular to an ultra-high temperature wear-resistant thermal transfer label and a preparation method thereof. Background technique: [0002] The temperature of label application is getting higher and higher. In the existing technology, labels are prone to peeling off or warping under high temperature conditions, and the printing coating will undergo strong yellowing under ultra-high temperature, resulting in unclear printed characters and graphics. Not even recognizable. Invention content: [0003] The purpose of the present invention is to provide an ultra-high temperature wear-resistant thermal transfer label and its preparation method. The ultra-high temperature wear-resistant thermal transfer label and its preparation method should solve the problem of the high-temperature label falling off or falling off at ultra-high temperature in ...
