Description

一种适于造纸的微粉碳酸钙的制备方法
技术领域
本发明涉及一种碳酸钙的制备方法，尤其是一种适于造纸的微粉碳酸钙的制备方法。
背景技术
重质碳酸钙，一般是由天然碳酸盐矿物如方解石、大理石和石灰石粉碎而制得，重钙具有白度高、纯度好、色相柔和等特点，因此被广泛用于人造地砖、橡胶、塑料、造纸、涂料、油漆、油墨、电缆、建筑用品、食品、医药、纺织、饲料、牙膏等行业，通常用作填充剂，或者是补强剂。
在造纸业中，碳酸钙其主要功能是用作填料，填充纸张中的空隙，改善纸张正面平滑度，增加纸张不透明度和白度，保证纸页尺寸稳定，降低生产成本，但目前的碳酸钙分散性不好，且多为湿法制备，工艺繁琐。
发明内容
本发明公开了一种适于造纸的微粉碳酸钙的制备方法，采用干法制备，工艺简单，且制得的微粉碳酸钙具有较好的分散性。
为实现上述目的，本发明的技术方案为：
一种适于造纸的微粉碳酸钙的制备方法，包括以下步骤：
S1. 对方解石原料进行粗碎和粉碎，得到100~200目的方解石粉体；
S2.将方解石粉体送入蒸汽气流磨进行粉碎，蒸汽气流磨中，过热蒸汽的温度为200℃~235℃、压力为0.8MPa～1MPa，粉碎后分级得粒径为0.3~2μm超微粉体；
S3.向超微粉体加入改性秸秆，混合均匀，得改性粉体；
S4.将改性粉体放入气流干燥机中干燥，即得微粉碳酸钙。
优选的，所述步骤S4中，气流干燥机中干燥管的温度为100~120℃、气流速度为20~30m/s。
优选的，改性秸秆的制备方法包括以下步骤：将秸秆粉碎至200~300目，加入磨浆机中进行磨浆，磨浆时通入氮气进行保护，同时加入浆料重量10~15%的双氧水漂白，漂白完成后蒸煮去除双氧水，在每100重量份的浆料中，加入0.2~0.5重量份的淀粉、0.1~0.3重量份的聚丙烯酸钠、0.02~0.05重量份的氢氧化钠、0.3~0.6重量份的硅烷偶联剂、0.01~0.03重量份的EDTA、0.02~0.06水溶性氧化聚乙烯蜡，搅拌均匀，干燥，粉碎，用微粉磨粉机磨粉，筛分出粒径<2μm的改性秸秆。
更优选的，在每100重量份的浆料中，加入0.3重量份的淀粉、0.2重量份的聚丙烯酸钠、0.03重量份的氢氧化钠、0.5重量份的硅烷偶联剂、0.02重量份的EDTA、0.03水溶性氧化聚乙烯蜡。
优选的，所述步骤S3中，超微粉体、改性秸秆的重量比为100:2.5~3。
以上所述的适于造纸的微粉碳酸钙的制备方法，具有以下优点：
（1）本发明采用蒸汽气流磨进行粉碎，以水蒸气为介质对方解石粉体进行气流粉碎，粉碎速度快，产品得率高，还能对碳酸钙进行表面改性，使得制得的碳酸钙易分散、不易团聚。
（2）本发明通过引入改性秸秆来改性微粉碳酸钙，秸秆通过改性，保留了秸秆本身的纤维，同时通过硅烷偶联剂、聚丙烯酸钠、淀粉来对秸秆进行加强，提高了秸秆的强度及润滑度，从而增强了碳酸钙的支撑强度，进而使碳酸钙作为造纸填料时能提高纸张的强度和韧性。
（3）本发明通过采用气流干燥机对碳酸钙进行干燥，加快了干燥的速度，同时还能更进一步对微粉碳酸钙进行表面改性，提高碳酸钙表面的平滑性，使微粉碳酸钙在纸张浆料中更容易均匀分散，从而使得纸张更均匀平滑。
