Description

调色剂制造方法 技术领域
本发明涉及一种用于静电照相、静电记录、静电印刷等静电图像显影装置 使用的调色剂的制造方法。 本发明基于申请日为 2011年 03月 12日、 申请号 为 201110059130. 9的中国发明专利申请, 该申请的内容作为与本发明密切相 关的参考文献引入本文。 背景技术
静电图像显影装置包括激光类的打印机、复印机、传真机及多功能一体机 等, 其成像用调色剂传统上通过颜料、树脂或其它成分的熔融捏合, 之后粉碎 并加入外添加剂后制得。但在粉碎后还需要进行分级才能得到可接受的窄粒度 分布。此外, 这种方法生产的调色剂, 其调色剂颗粒的小粒径化和粒度分布的 均匀程度有限, 因此, 使用这种方法生产的调色剂形成的图像, 难以获得足够 高的画像品质。
为解决上述问题, 近年, 通过湿法制备调色剂的应用越来越多。而湿法需 要在水体系或溶剂体系中进行, 难免会产生大量的废水或废溶剂。
悬浮聚合法是通过将颜料、蜡和如乙烯基类单体悬浮在水性溶剂中进行悬 浮聚合而制备调色剂。 由于悬浮体系不够稳定, 除了需要高速剪切力外, 在生 产过程中还需要添加大量的分散稳定剂,并且在生产过程中也不可避免会有一 些原料如蜡和颜料的游离及单体的残留, 从而增加废水或废溶剂处理的难度。
乳液聚合法是将如乙烯基类单体在水性溶剂中乳化成纳米级粒子,然后进 行乳液聚合, 凝集得到调色剂的方法。 该方法仍需要添加乳化剂, 引发剂, 凝 集剂等, 并且不可避免会有单体的残留, 最后需要采用多次洗涤去清除这些物 质, 也会产生大量的废水。
还有一些采有溶剂体系的生产方法, 如转相乳化的方法, 转相乳化是通过 将树脂溶解在有机溶剂中, 然后加入水进行相转移乳化, 由于溶剂的存在对环 境造成沉重的负担。
以上这些湿法生产调色剂过程中产生含有机溶剂、 表面活性剂、 凝集剂、 引发剂、 单体等的废水将对周围环境产生沉重的负担, 为此, 排放废水时需要 对其进行处理的设备, 从而导致调色剂生产成本的增加。
现有一种调色剂生产方法, 其生产的工艺歩骤如图 1所示, 这是一批调色 剂制造过程的流程图, 各歩骤具体内容如下:
S01物料、 有机溶剂混合分散: 将颜料、 蜡、 电荷控制剂、 粘合树脂粒子 及乳化剂等分散于有机溶剂中形成油相分散液;
S02乳化凝集: 然后加水乳化, 形成混合物分散乳液; 然后在对混合物分 散乳液施加剪切力的同时,向其中加入凝集剂,以形成调色剂凝集粒子分散液;
S03终止凝集: 加入凝聚终止剂使凝集过程终止; 此后经 S04蒸馏、 S05 过滤、 S06第一次洗涤过滤、 S07第二次洗涤过滤、 S08第三次洗涤过滤; S09混合: 加入作为外部添加剂的疏水性二氧化硅等进行混合即得到这一 批次制造的成品调色剂。 技术问题
以上生产过程中在 S04— S08歩骤中分别产生的含溶剂废水、 含凝集剂及 乳化剂的洗涤废水需要排放,必然增加废水处理的成本及对环境造成一定程度 的污染, 并且随洗涤废水清除的凝集剂和乳化剂未回收利用, 也造成少部分物 料的浪费。 技术解决方案
本发明的主要目的是提供一种在调色剂的多批次生产过程中无废水排放 的调色剂制造方法;
本发明的另一目的是提供一种在调色剂的生产过程中合理利用馏出液、滤 出液中有用溶剂的调色剂制造方法。
为实现本发明的主要目的,本发明提供的技术方案是调色剂分批次顺序制 造, 每一批次具有相同的工艺歩骤;
当前批次包括如下歩骤:
混合分散、 乳化凝集、 终止凝集、 蒸馏、 过滤、 第一次洗涤过滤、 第二次 洗涤过滤、 第三次洗涤过滤、 混合, 得到当前批次调色剂;
其中:
所述蒸馏歩骤中后馏出的馏出液作为所述当前批次洗涤过滤歩骤的洗涤 液;
所述蒸馏歩骤中先馏出的馏出液、 所述过滤歩骤的滤液、 所述第一、 二、 三次洗涤过滤歩骤的滤液全部在下一批次调色剂制造工序中使用。
更具体的方案是所述先馏出的馏出液在所述下一批次调色剂制造工序的 混合分散歩骤中使用,所述过滤歩骤的滤液与所述第一次洗涤过滤歩骤的滤液 在所述下一批次调色剂制造工序的乳化凝集歩骤中使用,所述第二次洗涤过滤 歩骤的滤液在所述下一批次调色剂制造工序的终止凝集歩骤中使用,所述第三 次洗涤过滤歩骤的滤液在所述下一批次调色剂制造工序的第二次洗涤过滤歩 骤中使用。 这样, 根据当前批次先、 后馏出液及滤液中含有可用物质的多少, 分别具体地在下一批次的各歩骤中按上下游歩骤对应使用,可以使当前批次的 馏出液及滤液的利用更加合理。 有益效果
由以上方案可见, 当前批次调色剂制造过程中的先、后馏出液及相关各歩 骤产生的滤液在当前批次或下一批次的调色剂制造过程中全部得以再次利用, 实现无废液排放, 从而不需进行污水处理后进行排放, 相对现有技术具有无废 液排放及省去了污水处理设备的优点。 附图说明

按照以上规律, 不断进行第三批次、第四批次…直到第 N批次制造的成品 调色剂。
本发明各实施例中, 蒸馏歩骤可以采用一般的减压蒸馏方式, 先得到的馏 出液为溶剂与水的混合物。 当馏出液开始分层时, 取出上层液。 上层液中, 溶 剂与水的比例为 85 : 15-90: 10。 对于可以与水互溶的溶剂, 可以根据重量来 确定先馏出液与后馏出液的界限。 由于先馏出液中大部分为溶剂, 水份的含量 较少, 因此可以作为下一批生产过程中的油性分散剂。 由于蒸馏歩骤中的后馏 出液中除了很少量的溶剂残存, 不存在其它杂质, 所以可以有效地对生产过程 的调色剂凝集物进行第一次洗涤以除去残留的凝集剂和乳化剂。并且残留的少 许溶剂和洗涤出来的凝集剂和乳化剂随着第一次洗涤液又加入到下一批生产 的乳化凝集的歩骤中, 没有含溶剂和含凝集剂及乳化剂的废水产生。
滤液及第一次洗涤液中包含了大部分的凝集剂和乳化剂,在下一批次生产 中以乳化水形式加入, 实现了凝集剂和乳化剂的循环利用。
检测出滤液及第一次洗涤液中的凝集剂和乳化剂含量后,可以根据损失的 凝集剂和乳化剂的量补加。从而达到各批次间的稳定与平衡。 由于洗涤过程不 可能彻底的洗净调色剂中的凝集剂和乳化剂, 因此会产生少量损失,但残留部 分量极少, 对各批次之间调色剂性能产生的影响已可以忽略不计。
另外, 加入含凝集剂和乳化剂的滤液及洗涤水之前, 用 3000-10000rpm 的搅拌速度下搅拌 1小时左右, 使各成分均匀分散。
第二实施例中,凝集剂和乳化剂主要存留在滤液及洗涤过程的第一批次洗 涤液中, 故为了原料的最大程度利用, 将此部分作为乳化水加入。但是由于其 中含有凝集剂, 为了避免产生粗大颗粒, 先加入含凝集剂量相对少的第一批次 洗涤液,然后再加入含凝集剂量相对多的滤液,相应的搅拌转速也应有所提高。
为说明根据本发明方法生产的调色剂的质量,以下给出若干批次的具体实 例。
第二实施例第一批次
将 5重量份的炭黑, 6重量份的聚丙烯蜡, 0. 8重量份的十二垸基苯磺酸 钠和 100重量份的聚酯树脂加入 60重量份的丁酮中, 用乳化装置高速剪切分 散 1小时。 保持温度在 30°C左右, 加入 300重量份的去离子水乳化, 得到混 合物分散乳液。 将上述混合物分散乳液置于反应器中, 调节搅拌转速为 400-600rpm, 加入 30重量份 1%的氯化镁溶液作为凝集剂。 加完凝集剂后, 继 续搅拌 20分钟, 当得到所需调色剂形状和粒径大小时, 加入 90重量份去离子 水, 得到了含调色剂凝集物的分散液。 将此调色剂凝集物分散液减压蒸馏,馏出液开始分层时, 取出上层液即为 先馏出液 60重量份, 得到后馏出液 120重量份。 经检测先馏出液中丁酮含量 为 53. 8重量份, 水含量为 6. 2重量份。
将蒸馏过的调色剂凝集物分散液过滤, 得到滤液 210重量份。经检测所含 乳化剂量为 0. 61重量份, 凝集剂为 0. 22重量份。
然后洗涤, 用后馏出液 120重量份对调色剂凝集物进行第一次洗涤, 过滤 后得到第一次洗涤液 108重量份, 经检测, 所含乳化剂的量为 0. 1重量份, 凝 集剂为 0. 06重量份。 分别用 100重量份去离子水进行第二次和第三次洗涤, 得到第二次洗涤液 90重量份, 第三次洗涤液 93重量份。
将洗涤后的调色剂凝集物在 40°C以下干燥, 得到体积平均粒径为 6. 5 μ m 的黑色调色剂颗粒,再加入作为外部添加剂的疏水性二氧化硅等进行混合即得 到黑色成品调色剂。
第二实施例第二批次
将 5重量份的炭黑, 6重量份的聚丙烯蜡和 100重量份的聚酯树脂加入第 二实施例第一批次蒸馏歩骤中收集到的 60 重量份先馏出液中, 补加乳化剂 0. 08重量份, 保持温度在 30 °C左右, 用乳化装置高速剪切分散 1小时, 得到 油相混合物分散液。将上述油相混合物分散液置于反应器中, 调节搅拌转速为 600-800rpm, 然后加入第一批次洗涤歩骤中收集的洗涤液 108重量份, 加入第 一批次过滤歩骤中收集到的滤液 210重量份, 补加 2重量份 1%的氯化镁溶液。 继续搅拌 20分钟, 当得到所需调色剂形状和粒径大小时, 加入第一批次第二 次洗涤歩骤中收集的洗涤液 90重量份终止凝集, 得到了含调色剂凝集物的分 散液。
将此调色剂凝集物分散液减压蒸馏,馏出液开始分层时, 取出上层液即为 先馏出液 62重量份, 继续蒸馏, 又得到后馏出液 118重量份。 经检测上层液 中丁酮含量为 54. 5重量份, 水含量为 7. 5重量份。
将蒸馏过的调色剂凝集物分散液过滤, 得到滤液 208重量份。
然后用第二批次中的后馏出物 118 重量份对调色剂凝集物进行第一次洗 涤, 用第一批次洗涤过程中的第三次洗涤水 93重量份及 7重量份去离子水对 调色剂凝集物进行第二次洗涤; 用 100重量份去离子水进行第三次洗涤, 并收 集各次的洗涤液在下一个循环批次中备用。
将洗涤后的调色剂凝集物在 40°C以下干燥, 得到如附图 4所示体积平均 粒径为 6. 6 μ m的黑色调色剂。
第二实施例第十批次
重复第二实施例第二批次的过程 9 次后得到第十批次过程中生产的黑色 调色剂颗粒, 如附图 5所示。 体积平均粒径 6. 8 μ ιη。
另外的实施例 1

以下对根据本发明制造出的调色剂进行的具体评价及实验结果加以说明。 评价方法:
( 1 ) 图像密度:
由分光密度仪 (X_Rite938, 由 X-Rite, Inc制造) 测定图像密度。 各评 价的图像是将上述各调色剂用于数字全色打印机。
(2) 转印率:
转印率通过测定印有规定图像或文本的纸面上调色剂的质量 Mp和感光体 上残存的调色剂的质量 Md, 据下式进行计算。 并据此标准评价转印率。
转印率 = {Mp/ (Mp+Md) } X 100%
(3) 背景雾密度的测定方法及其评价标准:
用分光密度仪测定和评价背景雾密度。其歩骤如下:用分光密度仪测定标 准纸预定区域的浓度。然后将一块 5X5cm的实心正方形图案印刷在标准纸上述 预定区域的上部区域, 再用分光密度仪测定标准纸预定区域的下部区域(预定 区域内, 实心图案之外的区域)的浓度。如此得到的浓度和标准纸的原始浓度 之间的差值定义为背景雾密度。
调色剂的图像密度, 背景雾密度, 转印率分为三个等级来评价: A : 优; B : 良; C : 差。
实验结果如表 1所示:
