Description
技术领域
本发明涉及碳酸钙粉体加工技术领域,尤其涉及一种耐酸腐蚀的碳酸钙粉体及其制备方法。
背景技术
碳酸钙作为橡胶、塑料制品的填料,可以提高制品的耐热性、耐磨性、尺寸稳定性、刚度及可加工性,并降低制品的成本,但是其表面有亲水性较强的羟基,呈现较强的碱性,耐酸腐蚀性差,因此需要对碳酸钙粉体进行改性,提高其耐酸腐蚀性,进而拓宽碳酸钙粉体的应用领域。
发明内容
本发明针对现有技术的不足,提供了一种耐酸腐蚀的碳酸钙粉体。
本发明通过以下技术手段实现解决上述技术问题的:
一种耐酸腐蚀的碳酸钙粉体,由以下重量份原料制备而成:碳酸钙100、碳化硅2-3、玻璃粉2-3、聚四氟乙烯3-5、氢氧化镁1-1.5、十八烷基三甲基氯化铵0.3-0.8、异丙醇5-8、油酸二乙醇酰胺硼酸酯0.1-0.3。
作为上述技术方案的改进,由以下重量份原料制备而成:碳酸钙100、碳化硅3、玻璃粉3、聚四氟乙烯5、氢氧化镁1、十八烷基三甲基氯化铵0.5、异丙醇6、油酸二乙醇酰胺硼酸酯0.2。
一种耐酸腐蚀的碳酸钙粉体的制备方法,包括以下步骤:
S1将碳酸钙、碳化硅、玻璃粉、氢氧化镁加入到搅拌机中,搅拌15min,得到混合物A;
S2将十八烷基三甲基氯化铵、异丙醇、油酸二乙醇酰胺硼酸酯进行混合,搅拌5min,得到混合液B;
S3将混合液B加入到混合物A中,并加入适量的去离子水,搅拌35min得到悬浊液C;
S4向悬浊液C中加入聚四氟乙烯,并搅拌5min,静置30min,得到产物D;
S5将S4中得到的产物D进行烘干,用研磨机研磨2-3h,得到改性碳酸钙粉体。
作为上述技术方案的改进,S3中搅拌得到悬浊液C后,对悬浊液C升温至60-80℃,并保持1.5h。
作为上述技术方案的改进,S4中搅拌温度保持在60-80℃,搅拌完成后,升温至90-110℃进行恒温静置30min。
作为上述技术方案的改进,S5中将S4中得到的产物D烘干后进行搅拌5-10min并冷却至室温,再用研磨机进行研磨。
本发明的有益效果:通过在碳酸钙粉体中添加碳化硅、玻璃粉、聚四氟乙烯以及氢氧化镁,提高碳酸钙粉体的耐酸腐蚀性,从而能够适应更多的应用环境;
通过添加十八烷基三甲基氯化铵作乳化液,改善碳酸钙以及其他各组分的表面张力,使之形成均匀稳定的分散体系;同时十八烷基三甲基氯化铵稳定性好,耐光、耐热、耐强酸腐蚀性好,从而提高碳酸钙粉体的耐酸腐蚀性。
通过添加异丙醇、油酸二乙醇酰胺硼酸酯并使其先与十八烷基三甲基氯化铵混合均匀,从而使得碳酸钙粉体在制备过程中各组分之间混合分散更均匀,性能更稳定。
