▎ 摘　　要

NOVELTY - Tin-based high-resistance thin film coating solution is prepared from a tin-based alloy, a matting solution, a dispersant, a cross-linking agent, graphene and ethanol. USE - Tin-based high-resistance thin film coating solution for tin-based high-resistance thin film (claimed). ADVANTAGE - The tin-based large-resistor film coating liquid ensures the conduction of the static electricity and does not affect the signal. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following; 1. a preparation method of the tin-based high-resistance thin film coating solution, which involves mixing matting solution, ethanol, graphene and dispersant, adding a tin-based alloy and cross-linking agent, and stirring to obtain a tin-based high-resistance thin film coating solution; and 2. a preparation method of a tin-based high-resistance thin film, which involves cleaning the substrate, preheating the substrate, and printing with a coating solution, and printing speed is 5-7 m/minute, and drying the film after illuminating to obtain a tin-based high-resistance film.
