【摘要】 随着造纸工业的不断发展,对造纸助剂的要求不断提高,新型多功能造纸助剂成为造纸助剂发展的主要方向。本研究选用已有的造纸用高低分子表面活性剂复配,研究他们之间的相互作用并考察其在造纸工业中的应用效果。第二章研究了传统高分子表面活性剂聚丙烯酰胺(PAM)与松香酸钾的相互作用及其在造纸中的应用,得出PAM与松香酸钾依靠氢键的相互作用形成复合物,并在近中性条件下实现了对再生浆的施胶,在一定添加量时具有较好的纸力增强效果。第三章初步研究了苯乙烯-丙烯酰胺-丙烯酸衍生物共聚物(BAA)与α-烯基磺酸钠(AOS)复合物的性质及相互作用,表明AOS与BAA形成复合物,复合物具有乳化的增效作用。第四章考察了AOS/BAA复合物用于制备分散松香胶的效果,探讨了复合物组成与松香组成对分散松香胶乳稳定性及最终施胶结果的影响,平行实验证明采用AOS/BAA复合物作为乳化剂可得到性能优良的产品。更多还原

【Abstract】 Along with the continuous development of papermaking industry, the request of papermaking additives’ performance increases continuously. And the development of new multifunctional papermaking additives becomes the main direction of papermaking additives. In this research we choose the polymeric and low-molecular surfactants that have been using in papermaking industry and study the interaction of the mixtures and investigate their applications in papermaking industry. In chapter 2, we research the interaction between a traditional polymeric surfactant polyacrylamide (PAM) and potassium abietate and study their applications in papermaking industry. The results showed that the complexes of PAM and potassium abietate formed depending on hydrogen bond . The complexes can be used under near neutral papermaking condition and the effects of improving paper sizing and paper strength simultaneously can be obtained. In chapter 3, a pilot study of the performances of the complexes of styrene-acrylamide-acrylic ramification copolymer (BAA) and alpha olefin sulfonate (AOS) was carried out. And the complexes showed emulsifying synergism effect within some certain scale. In chapter 4, the effect of the dispersed rosin size that made by using AOS/BAA complexes were investigated. The influence of built emulsifying agents and rosin ingredients on the stability of dispersed rosin size were also studied. The parallel experiments showed that good products can be obtained by using this built system.更多还原
