A kind of anti-adhering and acid-resistant tempered glass ink applied to automotive was prepared byusing the self-prepared varnish, black tempered pigment (the mixture of glass powders with low melting point andhigh-temperature ceramic melanin) and additives. Then, a synchronous thermal analysis was carried out, and theeffects of sintering temperature and time on the surface crystallization and morphology, the glossiness and the acid-resistance of the ink were analyzed by means of SEM and XRD. Finally, the sintering temperature and time wereoptimized. The results show that the softing point of glass powders with low melting point is 512℃, which is closeto the decomposition temperature of varnish resin of 470℃, so that glass powders can be used as a substitution ofresin for binding because they soften and melt in the sintering temperature range of 600700 ℃. Moreover, it isfound that the crystallization of the black tempered pigment at a relatively low temperature of 579.4 ℃may lowerthe sintering temperature and improve the anti-adhering property of the ink, that the optimal sintering temperatureand time are respectively 660℃and 4min, and that the prepared automotive tempered glass ink is of excellent anti-adhering property, acid resistance and glossiness.
