Abstract

The invention discloses a solid material block for back coating of a thermal transfer ribbon and a preparation method thereof, wherein the solid material block comprises the following raw materials inpercentage by weight: 30% to 35% of methyl methacrylate, 5% to 10% of isobornyl methacrylate, 0.5% to 1% of hydroxyl-containing silane coupling agent, 7% to 9% of hydroxyl-terminated silicone rubber,0.5% to 1% of amino-containing silane coupling agent, 40% to 45% of toluene, 5% to 10% of butanone and 0.5% to 1% of azodiisobutyronitrile. According to the invention, prepared back coating mother liquor is solidified into the solid material block by adopting a vacuum drying method, so that the storage and transportation of back coating material are facilitated, and the quality of the back coating material during use is ensured.

Description

technical field [0001] The invention relates to the technical field of heat transfer printing, in particular to a solid block used for back coating of heat transfer ribbons and a preparation method thereof. Background technique [0002] Thermal transfer ribbon is the basic consumable of thermal transfer technology. With the rapid development of the computer industry, the application field of this thermal consumable material is becoming wider and wider, gradually expanding from a single thermal typewriter used in the office field. The printing of barcodes, which can be applied to various fields such as food and medicine, plays an increasingly important role in the national economy. [0003] Thermal transfer ribbon Ribbons are generally composed of three parts: base film, heat-resistant back coating, and ink coating. On thermal transfer printers, the heat-resistant back coating is in direct contact with the thermal transfer head, and the thermal transfer ink In direct contact...
