Description

一种绝缘子用低灰砂比防裂硅酸盐水泥胶合剂
技术领域
本发明涉及一种绝缘子用低灰砂比防裂硅酸盐水泥胶合剂，属于胶合剂技术领域。
背景技术
陶瓷、玻璃绝缘子均由绝缘件、金属附件、水泥胶合剂组成。现有绝缘子生产习惯采用硅酸盐水泥胶合剂，随着电力工业的发展和电压等级的提高，绝缘子产品强度越来越高，JB/T4307胶合剂标准规定Ⅲ类胶合剂11天抗压强度不低于83.5MPa。为达到该强度，现有配方中水泥用量很大，灰砂比高，同时添加了一定量硅灰，虽然能提高胶合剂强度，但也带来了胶合剂流动性变差、干缩率高，易产生表面裂纹等问题。
发明内容
为解决现有技术的不足，本发明提供一种绝缘子用低灰砂比防裂硅酸盐水泥胶合剂，具有灰砂比低、胶合剂流动性好、强度高、防裂性的特点，可以满足高吨位绝缘子生产需要。
本发明所采用的技术方案为：
一种绝缘子用低灰砂比防裂硅酸盐水泥胶合剂，胶合剂由以下重量百分比的组分组成：硅酸盐水泥35%-45%，胶装砂35%-45%，含锆硅灰1.5%-2.5%，高炉矿渣粉3%-5%，膨胀剂0-3%，聚丙烯腈纤维0.02%-0.06%，减水剂0.10%-0.23%，保水剂0-0.03%，水10%-13%，消泡剂0.002%-0.006%。
优选的是，硅酸盐水泥为52.5硅酸盐水泥或52.5R硅酸盐水泥。
进一步的优选，含锆硅灰中SiO2含量≥94%。
进一步的优选，高炉矿渣粉的比表面积≥700m2/kg。
进一步的优选，减水剂包括高减水型聚羧酸减水剂和保坍型聚羧酸减水剂，其中，高减水型聚羧酸减水剂在胶合剂中重量百分比为0.10%-0.18%，保坍型聚羧酸减水剂在胶合剂中重量百分比为0-0.05%。
本发明的有益效果在于：
本发明的胶合剂配方灰砂比低，水泥用量只有现有配方40%-60%，采用高流动性的含锆硅灰、超细高炉矿渣，提高了胶合剂流动度和抗压强度，改善了胶合剂耐老化性能；两种聚羧酸减水剂及保水剂的应用，改善了胶合剂工艺性能；聚丙烯腈纤维及膨胀剂降低了胶合剂干缩率，减少了表面开裂现象。
