超细硫酸钡的制备方法
摘要：
本发明属于化工技术领域，涉及一种制备超细硫酸钡的方法，具体为1mol可溶性硫酸盐和1mol可溶性钡盐的水溶液在添加剂作用下反应生成超细硫酸钡；可溶性硫酸盐水溶液和可溶性钡盐水溶液的质量浓度为10％～30％；将0.414～16.56g添加剂溶于207～2070g水中，加入1％～40％的上述可溶性硫酸盐水溶液，搅拌制成底液；底液中滴加可溶性钡盐水溶液和余下的可溶性硫酸盐水溶液，搅拌；过滤、洗涤、干燥、粉碎即得。本发明的超细硫酸钡平均粒径为0.2μm～0.5μm，可广泛应用于涂料、油墨、造纸、工业塑料、高档电绝缘塑胶、橡胶制品等领域。
摘要（英）：

The invention relates to a method for preparing superfine barium sulfate and belongs to the technology field of chemical industry, in particular to a method for preparing the superfine barium sulfate in the reaction between 1 mol soluble sulfate aqueous solution and 1 mol soluble barium salt aqueous solution in presence of the additive; the mass concentration of both solutions is 10%-30%; The method includes dissolving 0.414-16.56g additive into 207-2,070g water, adding 1%-40% of the soluble sulfate aqueous solution, and stirring to obtain base solution; adding the soluble barium salt aqueoussolution and remaining soluble sulfate aqueous solution into the ground solution, stirring; and filtering, washing, drying and pulverizing. The inventive superfine barium sulfate has an average particle diameter of 0.2-0.5 Mum; and can be widely used in fields of coating, ink, papermaking, industrial plastics, high grade electrical insulating plastic, rubber article, etc.
