摘要

采用乳液法制备二氧化钛(TiO2)/滑石粉复合填料,并将其应用在装饰原纸中.结合油包水型(W/O)乳液的拟三元相图,寻找合适的乳液体系,并利用响应曲面试验对TiO2/滑石粉复合填料的制备工艺进行优化.结果表明,环己烷比正庚烷更适合作为油相,正丁醇的用量影响着乳液的稳定性;复合填料制备的最优工艺为:Tween80/正丁醇的质量比为1∶1,乳化剂/环己烷的质量比为4∶6,水/环己烷的质量比为1∶3,滑石粉/钛酸四丁酯(TBT)质量比为1∶4,在此条件下制备的复合填料加填在装饰原纸中,得到的不透明度为97.0%,白度为84.0%ISO.通过扫描电子显微镜(SEM)、X射线能谱仪(EDS)及X射线衍射(XRD)分析方法对复合填料进行表征,结果显示,滑石粉表面包覆了一层致密均匀的TiO2,其晶型结构为锐钛矿型.

Abstract

Titanium dioxide(TiO2)/talc composite filler was prepared by emulsion method and used in decorative base paper.Its preparation process was optimized by combining the pseudo-ternary phase diagram and response surface method of W/O emulsion.It was found that cyclohexane was more suitable for oil phase than n-heptane,and the amount of n-butanol affected the stability of emulsion.The optimum preparation process of the composite filler was Tween80/n-butanol=1∶1(weight ratio),emulsifier/cyclohexane=4∶6(weight ratio),water/cyclohexane=1∶3(weight ratio),talc/tetrabutyltitanate(TBT)=1∶4(weight ratio),resulting in an opacity of 97.0%and a whiteness of 84.0%ISO for decorative base paper.The composite filler was characterized by the methods such as scanning electron microscopy(SEM),X-ray spectrometer(EDS)and X-ray diffraction(XRD).The results showed that talc was coated with anatase type TiO2.
