Abstract
含有硝基氧或羟胺结构部分的经选择的氯代醇和阳离子化合物可有效地稳定纸浆或纸,尤其含有木质素的纸浆或纸,抵抗由于光的损害作用所引起的泛黄和变色。这些化合物在造纸过程中的不同位置添加,尤其在液体处理部位,使得对纸浆或纸具有高亲和力的水溶性或水可分散性材料的需要成为不可缺少的。这些性能常常因为存在了选自UV吸收剂、阻聚剂、硝酮、萤光增白剂和金属螯合剂的一种或多种助添加剂而得到进一步增强。羟胺或它们的盐,苯并三唑或二苯甲酮UV吸收剂和金属螯合剂的结合是特别有效的。
Description
本发明涉及具有对纸浆或纸(尤其含有木质素的纸浆或纸)有高亲和力的硝基氧或羟胺结构部分的新型氯代醇或阳离子化合物,该化合物可用于防止在纸浆或纸中,尤其在仍然含有木质素的纸浆或纸中亮度的损失和增强其抗泛黄的能力。这些性能常常因为存在了选自UV吸收剂、阻聚剂、硝酮、萤光增白剂和金属螯合剂的一种或多种助添加剂而得到进一步增强。羟胺或它们的盐,苯并三唑或二苯甲酮UV吸收剂和金属螯合剂的结合物是特别有效的。
发明背景
高产率和超高产率木质纸浆经历快速光诱导的变色,尤其当它们暴露于户内荧光和日光中的近紫外线辐射(波长300-400毫微米)时。这一特性将它们的用途限于短寿命、低价值的纸类产品。高产率和超高产率木质纸浆能够漂白到高水平的白度。如果这些白度能够被稳定化防止变色,则这些漂白的高产率纸浆能够代替大量的更昂贵全漂白、低产率化学纸浆。
这一变色归因于高产率纸浆的总计约20-45%(质量)的高木质素含量。苯氧基基团是该反应机理中的关键中间体。已经提出几种光诱发的反应来说明这种基团在木质素中的形成,如苯甲酰甲基芳基醚基团的芳基醚键的分裂,或由木质素中的饱和芳基-甘油β-芳基醚结构形成的羰游离基的破坏。该苯氧基被其它以氧为中心的基团(烷氧基和过羟基)所氧化,形成黄色生色团。(C.Heitner,″Photochemistryof Lignocellulosic Materials″,C.Heitner,J.C.Scaiano,Eds.;ACS Sym.Ser.531,1-25(1993)。)
I.E.Arakin等人,Khymiya drevesiny(Chemistry of Wood),1982,No.2,114和A.D.S ergeev等人,同前,1984,No.5,20公开了亚胺氧基的使用,如TEMPO(1-氧基-2,2,6,6-四甲基哌啶)可用于使用一段氧-苏打(碱)过程的木材去木质素作用,但没有提及或建议由TEMPO提供的防止从该处理木材制得的纸张或纸浆的光诱导变色的任何活性。
EP 717,143和WO 97/36041描述了改变、减少或漂白木质素和含木质素材料的多组分体系,它包括氧化催化剂,和N-羟基介体化合物如N-羟基邻苯二甲酰亚胺或二烷基羟胺。这些参考文献致力于木材的去木质素作用。没有提及或建议由N-羟基化合物提供的防止由此类处理木材制得的纸张或纸浆的光诱导变色的任何活性。
V.I.Khodyrev等人,Vysokomol soyed,A29,No.3,616(1987)[Polymer Sci.U.S.S.R.,29,No.3,688(1987)]中揭示,氧的光诱发氧化作用会引起纤维素纺织材料如亚麻或棉花的老化,和纤维素的光稳定性能够通过光稳定剂如UV吸收剂,苯并苯酚类和1-氧基-2,2,6,6-四甲基-4-羟基哌啶来改进。该UV吸收剂没有提供保护作用,实际上是有害的。作者指出,稳定的硝酰基基团会与纤维素中的烷基相互作用,使其获得有益的稳定作用活性。该作者没有提出这一稳定作用活性能够在从其制得的木质纸浆和/或纸中成功地利用。
M-K.Syler等人,J.Assn.Paper Pulp Tech,29,135(1990)中揭示,经选择的金属盐如硫酸镁和低级链烷酸会抑制在漂白纸浆中的回色。
P.Fornier de Violet等人,Cellulose Chem.Tech.,24,225(1990)显示,UV吸收剂和氢给体剂如硫醇类、抗坏血酸等的使用有助于防止过氧化氢漂白的木质纸浆的光诱发变色,但是,链断裂剂如位阻酚和位阻胺(具有>N-H或>N-CH2-结构部分)对于防止光诱发变色没有作用或甚至有不利影响。
R.Agnemo等人,6th International Symposium on Wood andPulping Chemistry,Appita,1991,证实了游离羟基加上木质素会导致在纸浆和纸中产生不希望有的光致泛黄。
S.Omori等人,J.Assn.Paper Pulp Tech,48,1388(1993)描述了抗氧化剂和UV吸收剂对光致回色的作用和总结出抗氧化剂和UV吸收剂的联合使用可以防止回色和在该活性中具有协同效应。
M.Paulsson等人,8th International Symposium Wood andPulping Chemistry,赫尔辛基,1995,说明了未漂白的纸或过氧化氢漂白的TMP纸浆的有效光稳定化可以通过乙酰化来获得。
已经建议了各种不同的途径来抑制机械纸浆的泛黄。这些包括:游离基清除剂和抗氧化剂;UV屏蔽剂;在生色团形成之后消除它们;通过烷基化或乙酰化对木质素的化学改性;阻聚剂;和组合使用的两种类型的助添加剂。Z-H.Wu等人,Holzforschung,48,(1994),400讨论了游离基清除剂如苯基-N-叔丁基硝酮在减少机械制浆过程中生色团的形成方面的用途并得到更具光稳定性的纸浆。
C.Heitner,“Chemistry of Brightness Reversion and ItControl,Chapter 5”,Pulp Bleaching-Principles and Practice,C.W.Dence,D.W.Reeve,Eds.,TAPPI,Atlanta,1996,183-211页,概述了在含有木质素的纸浆,如热机械(TMP)和化学热机械(CTMP)纸浆的热和光诱发变黄方面的现状,显示了这些不希望有的效果的严重程度,一般性讨论了用于解决这一问题的当时已有技术的方法。这些包括漂白,使用亚磷酸酯,UV吸收剂,聚亚烷基二醇和自由基清除剂如抗坏血酸,硫醇类,硫醚,二烯烃和脂族醛和螯合剂如乙二胺四乙酸(EDTA)。该著作者作出结论,虽然取得了较大的进展,但是要发现含有木质素的纸浆和/或纸的亮度损失和不希望有的泛黄问题的成功的和实际的解决方法仍然需要付出努力。
同时待审的专利申请序列号No.09/119,567;09/234,253;60/116,687和60/116,688描述了潜在的解决方案,其中将所选择的位阻胺硝基氧化物,位阻胺羟胺,N,N-二烷基羟胺或它们的盐与所选择的UV吸收剂和金属螯合剂联合使用可以在机械或化学纸浆或纸(尤其是仍然含有大量木质素的机械纸浆或纸)中防止亮度的损失和增强抗泛黄的能力。
发明详述

j.在使用压片箱的压延机上;
k.在机外涂布机或压胶器中的纸张上;和/或
l.在卷缩控制装置中。
显然,添加稳定剂添加剂的准确部位将取决于所使用的具体设备,所使用的具体工艺条件等。在一些情况下,可以在一个或多个部位添加添加剂以获得最佳的效果。
如果稳定剂或其它助添加剂它们本身不是“水溶性的”,则它们可以在应用之前利用标准方法加以分散或乳化。另外,稳定剂和/或助添加剂可以配制到纸张施胶或纸张涂敷配方中。
本发明的稳定剂也可用作有机材料,尤其有机聚合物的光稳定剂。因此,它们可以有利地用于本体聚合物如聚烯烃,膜,纤维或用于涂料中。基底材、助添加剂和满足此目的的具体应用方式包括现有技术领域中已知的那些,例如按照在US-5948836的3栏37行至9栏61行(基底材);1栏46行至3栏36行,和17栏65行至25栏30行(助添加剂);和17栏39-61行,26栏33-39行,和同样26栏52行到27栏18行,和28栏11-17行(应用方法)中所述。
下面的实施例仅仅是用于举例说明的目的,不应被认为以无论任何方式限制本发明。
手抄纸处理
全部的添加剂通过将合适wt%的添加剂结合物作为水溶液(当添加剂是水溶性的时)形式或作为在1∶1的乙醇/二烷中的溶液形式用注射器注射到漂白的热机械纸浆(BTMP)亮度方形料样(4厘米×4厘米)之上来应用。该夹定片材被风干1天。
在被控制的强度的条件下利用曝光来处理之前和之后,记录手抄纸的亮度。
通过在装有八只在5700埃下有最高光谱输出功率的荧光灯(总输出功率大约比正常办公室荧光灯高43倍)的风扇冷却的光箱中让处理过的片材进行加速光诱导泛黄,来进行加速试验。该灯与被照射的手抄纸相距大约10英寸。
将处理过的手抄纸以6英尺的标称距离放置在呈现正常冷白色荧光的办公室灯光下的桌面上,来进行环境试验。
在两种情况下,ISO亮度是作为光解时间的函数来跟踪并按常规方式换算为退色值(PC值)。
退色(PC)值被定义如下:
PC=[(k/s)之后-(k/s)之前]×100
k/s=(1-Rinf)2/2Rinf
其中k和s分别是吸收和散射系数,并且Rinf是ISO亮度的值。
在Rinf和发色团浓度之间的关系是非线性的,而PC值相对于样品中发色团的浓度粗略地成线性关系。
低PC值是所希望的,因为它们表示较低的泛黄性。
在使用环境试验条件下,将未处理的BTMP手抄纸与60天后的牛皮纸(Kraft)手抄纸进行对比,BTMP手抄纸的PC值是大约10,而牛皮纸的PC值是大约0.39。在暴露于环境光之后,该牛皮纸手抄纸明显比未处理的BTMP手抄纸有更浅的黄色。
加速泛黄试验的入射光通量(实施例1-10)比正常办公室荧光灯高43倍,这可通过A.W.Speery SLM-110数字光功率计来测量。跟踪记录手抄纸的亮度并与按同样方式曝光的未处理片材对比。该处理片材表现出显著的抗泛黄能力,这可以从以下所述看出。
