  Chlorohydrin and cationic compounds having high affinity for pulp or paper

  摘要：

  选定的含氮氧自由基或羟肟官能团的氯水化物和阳离子化合物对于稳定纸浆或纸张，特别是含有木质素的纸浆或纸张，抵御光的不良影响引起的黄变和变色非常有效。这些化合物在造纸过程的各个阶段，特别是在湿端添加，因此需要具有高亲和力的水溶性或水分散性材料是必不可少的。这种性能通常还可以通过存在于紫外线吸收剂、聚合抑制剂、亚硝基、荧光增白剂和金属螯合剂等组中选择的一种或多种共添加剂的存在而进一步增强。羟肟或其盐、苯并三唑或苯并酚紫外线吸收剂和金属螯合剂的组合特别有效。

  Selected chlorohydrin and cationic compounds containing nitroxide or hydroxylamine moieties are effective in stabilizing pulp or paper, especially pulp or paper containing lignin, against yellowing and discoloration due to the adverse effects of light. These compounds are added at various points in the paper-making process, especially at the wet ends, making the need for water soluble or water dispersible materials having high affinity for pulp or paper essential. This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents and metal chelating agents. Combinations of hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective.
