摘　　要：四碱式硫酸铅(4BS)是一种重要的铅酸电池性能改善材料,引入十二烷基苯磺酸(DBSA)分散剂来制备4BS,以解决传统方法中因团聚所造成的颗粒分布不均和分散不好的问题。考察了DBSA用量、液固比、煅烧温度、煅烧时间对产物纯度和粒径的影响,并确定了最佳工艺条件:n(Pb^(2+))∶n(SO_4^(2-))=5∶1,n(PbO)∶n(DBSA)=9∶1,液固比L/S=3,水浴温度为85℃,煅烧温度为550℃,煅烧时间为5 h。对4BS产品进行XRD和SEM分析表明,所得4BS产品分散均匀,粒径在5μm以下,纯度达到98%以上。Tetrabasic lead sulfate（ 4BS） is an important material which can improve the performance of lead-acid batteries,dodecyl benzene sulfonic acid（ DBSA） was introduced to prepare 4BS as dispersant,this method can solve the problem of uneven distribution and dispersion of particle size resulting from aggregation in the traditional method; the effects of DBSA content,the radio of liquid to solid,calcining temperature and calcining time on the purity and particle size of the product were investigated,and the optimum process conditions were determined： n（ Pb^2-） ∶ n（ SO4^2-） = 5∶ 1,n（ PbO） ∶ n（ DBSA） = 9∶ 1,the radio of liquid to solid（ L/S） is 3,the temperature of water bath is 85℃,the calcining temperature is 550℃,the calcining time is 5 h. The products of 4BS was analyzed by XRD and SEM. The results showed that the products of 4BS were dispersed evenly,the particle size was under 5 μm,the purity of 4BS was more than 98%.
