Description

一种造纸填料用碳酸钙及其制备方法
技术领域
本发明化工填料领域，具体涉及一种造纸填料用碳酸钙及其制备方法。
背景技术
近年来纸张加填技术得到广泛应用.填料加填具有许多优点。填料的使用具有以下优点:填料价格便宜，用填料代替纤维能带来显著的经济效益;填料能够提高纸张的光学性能，如白度和不透明度；填料能够提高纸张匀度、印刷适性和形稳性。但是随着加填量的增加，产生了许多问题，如纸张强度的下降，纸张施胶效果降低.纸料留着率的下降等等。
传统填料加填纸张的缺陷限制了填料的应用。为了克服或降低填料加填对纸张的不利影响.填料改性技术得到了很大的发展。目前关于填料改性方面的研究主要集中在填料的预絮聚、填料表面改性、细胞腔加填、合成填料等技术。
淀粉具有羟基结构.可以和纤维形成氢键，把淀粉沉淀在填料的表面，能够使填料和纤维之间形成结合力。
发明内容
本发明提供一种造纸填料用碳酸钙及其制备方法。
一种造纸填料用碳酸钙，其特征在于，包括以下材料按照重量份配制而成：
碳酸钙 70-85份
淀粉 5-20份
硬脂酸钠 5-10份
淀粉交联剂 1-3份。
作为优选方案之一，所述的淀粉交联剂是六偏磷酸钠。
其中，造纸填料用碳酸钙的制作方法，包括以下步骤：
（1）称量适量的淀粉加入烧瓶中，加入水，配成淀粉悬浊液，高速分散10min，加热糊化30min；
（2）将硬脂酸钠加入到淀粉悬浊液中，高速分散10-15min，形成复合物；
（3）把质量浓度为25%的碳酸钙悬浮液加入到复合物中，并加入淀粉交联剂六偏磷酸钠，高速分散20-30min，降温，过滤即得。
本发明的有益效果是：本发明采用碳酸钙为原材料，通过使用淀粉进行改性，改性后的碳酸钙作为造纸填料使用，能有效提高纸料的留着率，提高白度，抗张强度和耐破度明显提高。该操作步骤简单，材料廉价易得。
