The invention relates to a glaze leadless cadmium free ceramic pigment, consisting of 70% to 92% by weight of 8% to 30% by weight of the flux and the flux of chemical reagent, by weight percent: 4.17-18.5 SiO down 2 from 30 to 60%, down B 2 O down 3 from 5 to 35%, down Al 2 O: 3, Na: 1.5 ~ 15% 2 O1.5 ~ 10%, K: 2 O1.5 ~ 10%, Li: 2 O0 to 8% ZrO, down 2 from 0 to 10%, SnO down 2 from 0 to 10%, down 2 from 0 to TiO 5%, CoO0 ~ 10%, ZnO0 ~ 15%, BaO0 ~ 5%, CaO0 ~ 5%, La: 2 O: 3, Nd: 0 ~ 2% - 2 O: 3 0 ~ 2%; in turn, according to the following steps: the preparation of flux: mixing flux and color, ball milling, and then re burning, fine grinding of pigment products. The present invention glaze ceramic pigment not only high gloss, good thermal and chemical stability, color pure, bright color, low cost, pigment color variety, can completely replace the traditional lead and cadmium series pigments, and the composition of no heavy metals lead and cadmium, lead and cadmium is not safe and reliable.

技术介绍
陶瓷制品最为广泛的装饰方法是釉上彩,釉上彩是在750~850℃的低温下使用,所以传统的生产工艺中需要在熔剂中加入30~50%的氧化铅以使陶瓷釉上颜料的烧烤温度范围宽且发色纯正,并且氧化镉色剂又以独特绚丽的色彩成为陶瓷制品装饰领域不可或缺的色系,但铅、镉类陶瓷颜料在生产和使用过程中,对大气、水资源的污染和对人体的伤害已经引起世人关注,尤其是餐具、饮具表面的铅、镉溶出是潜在的致癌物质,对人们的健康构成威胁。为减少和根除铅、镉等重金属的毒害,国内外陶瓷装饰业的科研及生产部门一直做着不懈的努力。英国专利CB2250285A中专利技术了一种无铅的陶瓷颜料熔剂,它的摩尔百分组成为SiO250~70%、Bi2O310~40%、Al2O33~30%、B2O 0~15%、Li2O 0~10%、Na2O 0~10%、K2O 0~10%、MgO 0~5%、CaO 0~10%、ZnO 0~10%、ZrO20~5%、TiO20~5%、SnO20~5%、MoO30~3%、稀土0~3%。中国专利CN1044595C中专利技术了无铅、无镉釉上颜料的熔剂摩 ...
