摘要： 采取自制的调墨油、耐酸钢化颜料黑(低熔点玻璃粉和高温陶瓷黑色素的混合物)和助剂制备了抗粘、耐酸的汽车钢化玻璃油墨,进行了同步热分析,并采用SEM 和XRD 研究了烧结温度和时间对油墨釉层表面析晶、表面形貌及其对釉层光泽度和耐酸性的影响,确定了油墨的最佳烧结温度和时间. 结果显示:低熔点玻璃粉的软化点为512 ℃,与调墨油树脂的最终分解温度(470℃)较接近,从而在600700℃的烧结温度范围内可以充分熔融流动并代替树脂作为连结料;钢化颜料黑在579.4℃开始析晶,起到了降低油墨烧结温度和抗粘的作用;采用SEM 和XRD 研究了烧结温度和时间对油墨釉层表面析晶、表面形貌及对釉层光泽度和耐酸性的影响,确定了油墨的最佳烧结温度和时间分别为660℃和4min; 所制备的油墨具有良好的抗粘性、耐酸性以及较好的光泽度.

Abstract:

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.

Key words: automotive tempered glass ink, sintering process, acid resistance, anti-adhering property
