摘　　要： 对一种新合成的石油树脂施胶剂在漂白硫酸盐木浆中进行了应用实验。探讨了施胶时胶料用量、硫酸铝用量、pH值等因素对施胶效果的影响 ,得到的最佳施胶工艺为 (相对于绝干浆的质量分数 ) :胶料2 %、硫酸铝 3%、阳离子聚酰胺多胺环氧氯丙烷 (PAE) 0 .2 %、碳酸钙 <2 0 % ,pH值 6 .2 ,采用逆向施胶。实验结果表明 ,石油树脂施胶剂在上述工艺条件下有较好的施胶效果 ,加填碳酸钙后可明显提高纸张的白度和不透明度。 The application of a novel petroleum resin sizing agent in the bleached sulfate wood pulp was studied.The factors such as the dosages of sizing agent,aluminum sulphate and pH value which could influence sizing efficiency were discussed in detail. The optimum sizing condition was as follows: pH value 6.2, aluminium sulfate 3 %, sizing agent 2 %, calcium carbonate 20 % and 0.2 % sizing assistant——cationic polyamide polyamino-expoxy chloropropane (PAE) with reversed sizing method. The experimental results indicated that petroleum resin sizes could be used as an effective sizing agent under the above mentioned optimum conditions. In addition, CaCO_3 could be used as an additive under the above mentioned conditions, to improve the brightness and opacity of paper sheet obviously.
