Abstract

The invention discloses an organic silicon resin modified heat-resistant back coating material, which is prepared from the following components in parts by mass: 2 to 4 parts of methyl MQ silicon resin, 180 to 200 parts of simethicone, 18 to 20 parts of methacryloyloxypropyltrimethoxysilane, 6 parts of dibutyltin dilaurate and 5800 to 6800 parts of organic solvent. According to the using method of the organic silicon resin modified heat-resistant back coating material, a transmission roller drives a PET base film to keep uniform motion, and the surface of the PET base film is uniformly coated with the organic silicon resin modified heat-resistant back coating material; and the redundant organic silicon resin modified heat-resistant back coating material on the surface of the PET base film is scraped off, the release layer and the ink layer are coated, and drying is carried out to finally obtain the finished product of the thermal transfer ribbon. The production process is simple, the raw material cost is low, the cost is considered while the heat resistance of the thermal transfer ribbon is improved, and the large-scale industrial production requirement of a factory is met.

Description

technical field [0001] The invention relates to the field of heat-resistant coating materials for thermal transfer carbon ribbons, in particular to a silicone resin modified heat-resistant back coating material and a preparation method and application method thereof. Background technique [0002] Thermal digital printers use thermal transfer technology to transfer specific information carriers to substrates to form numbers, images, barcodes, two-dimensional codes, etc. Thermal transfer printing technology has a very wide range of applications not only in highly specialized fields such as military industry, aerospace and navigation, but also in many commercial and civilian fields such as food and drug packaging, clothing labels, mechanical products and digital products. [0003] The transfer ribbon is the core component of the thermal transfer printer during operation. It is composed of heat-resistant back coating, PET base film, release layer and ink layer. When performing t...
