阳离子分散松香施胶剂施胶性能的研究

阳离子分散松香施胶剂（ＣＤＲＳ）作为松香系列施剂的新型换代产品之一,其施胶性能是评价其应用价值的重要依据。本研究对自制的ＣＤＲＳ在不同条件下的施胶效果进行了试验并与现有的商品松香施胶剂进行了对比。中碱性条件一的施胶试验结果表明,ＣＤＲＳ相对阴离子分散松香胶而言,消耗助留剂硫酸铝的量约低５０％,而且在ＰＨ６．５－７．５条件下具有较好的施胶效果。     

叔胺型与季铵型阳离子分散松香施胶剂的性能比较

用苯乙烯、丙烯酸酯与甲基丙烯酸二甲胺乙酯或二甲基二烯丙基氯化铵的共聚物作乳化剂分别制备了叔胺型阳离子分散松香施胶剂(SYM-1)和季铵型阳离子分散松香施胶剂(JYM-1),并比较了它们的施胶性能。实验结果表明,叔胺型高分子表面活性剂(SYS-1)的电荷密度和SYM-1的施胶性能受pH值影响较大,SYM-1的施胶度在相同施胶条件下比JYM-1大10 s以上,但在含碳酸钙抄纸体系中失去其施胶性。季铵型高分子表面活性剂(JYS-1)的电荷密度不受pH值的影响,用硫酸铝和聚乙烯胺复合物作定着剂时JYM-1在含碳酸钙抄纸体系中的施胶度大于5 s。     

中性松香施胶剂的制备及施胶特性

本研究制备了多种烃基松香酯－松香施胶剂及松香甘油酯－松香施胶剂,并对其在中、碱性造纸施胶中的应用进行了探讨。施胶结果表明,松香甘油酯－松香施胶剂能有效地用于中、碱性施胶,然而其它烃基松香酯－松香施胶剂在同样条件下却无施胶效果。这意味着中性松香胶施胶剂的制备及性能并非完全取决于松香羧基的改性而是松香酯的结构有关。虽然碱性填料碳酸钙的添加引起一定程度的施胶效果的下降,松香甘油酯－松香中性施胶剂在含有碳

超细分散松香胶的制备

松香胶是造纸施胶方面应用极广的一种固─-液分散体系。松香（分散相）的颗粒直径愈小，施胶效果愈好；在同样分散度下，游离松香含量愈高，施胶效果愈好。超细分散松香胶因其分散相小，分散均匀，游离松香含量高，稳定性高，在造纸工业上有广阔的前景。分散松香胶的普及很快。但由于对制胶机理研究的不够深人，生产中往往出现颗粒粗大、粘度大、不易分散、稳定性低、吨纸松香耗量高等缺点。我厂是生产高分散松香胶乳化剂的专业厂家，对超细分散松香胶，从制胶机理到工艺都做过深入研究。按我们的配方和工艺制得的超细分散松香胶，质量稳定…

Preparation and sizing mechanisms of neutral rosin size II: functions of rosin derivatives on sizing efficiency

Four rosin derivatives, including rosin esters and rosinamides, were synthesized and used to prepare neutral rosin sizes. Their effects during sizing are discussed in detail. Compared to natural rosin, the rosin derivatives had nearly no effect on sizing even at high retention levels in paper. However, the rosin derivatives in the rosin sizes improved the stability of the emulsion size particles, and there was good correlation between the sizing effect and the stability of the emulsion sizes under neutral to alkaline conditions. On the other hand, the structure of the rosin derivatives significantly influenced the stability and sizing effect of the neutral rosin sizes. In particular, for glycerin rosin ester-rosin sizes, the emulsion stability and sizing effect increased with an increasing proportion of dirosinate, among the glycerin rosin esters. Consequently, it was suggested that the rosin derivatives hardly contribute to the sizing performance of paper but predominantly function to stabilize the neutral rosin size particles, thereby improving the efficiency of the size under neutral to alkaline sizing conditions. Also it was supposed that glycerol dirosinate in the neutral rosin size would probably enable formation of a more stable particle structure to prevent the destructive action of the OH^– ion.This research was presented in part at the 48th annual meeting of the Japan Wood Research Society, Shizuoka, April 1998

Application of cationic polymer prepared from sulfuric acid lignin as a retention aid for usual rosin sizes to neutral papermaking

Cationic polymers that acted as the retention aids for usual rosin sizes in neutral papermaking were prepared from sulfuric acid lignin (SAL), one type of acid lignin. To convert SAL to the cationic polymer (MP-SAL), SAL was phenolated and then treated by the Mannich reaction to introduce the amino groups. In the MP-SAL single system, MP-SAL exhibited high sizing effectiveness in neutral papermaking with the rosin emulsion size. However, MP-SAL showed no sizing effectiveness when soap rosin size was used. MP-SAL showed increased sizing effectiveness as the pK _a of the introduced amino group increased. From this and comparison of the sizing degrees of MP-SAL and polyethylenimine, which possesses a linear structure, it was suggested that the sizing effectiveness was not only affected by the charge density and molecular weight, but also by the basicity of the introduced amino groups and the molecular structure of the retention aid. In the alum–MP-SAL dual system, alum and MP-SAL synergistically enhanced the sizing effectiveness in the rosin emulsion sizing at neutral pH. In turn, this allowed a decrease in the MP-SAL dosage and resulted in a small decrease in brightness.Part of this report was presented at the 48th Lignin Symposium, October 2003, Fukui
