摘要:
Using C5, C9 petroleum resin as rosin extender emulsitied together with rosin to prepare cationic rosin size, to study the stability and the sizing effect of cationic dispersed rosin size when different proportion of C5 ,C9 petroleum resin is added. The results show that no matter join the Cs ,C9 petroleum resin respectively or join the C5, C9 petroleum together to prepare cationic dispersed rosin size,the sizing performance is better than the normal rosin size. And when the C5 petroleum resin used alone as rosin extender and when the amount of C5 petroleum resin used 20 %, size amount used 0.8 1.0% ,the addition levels of alum used 2-2.5% ,it can achieve satisfied sizing effect;when C9 petroleum resin used alone as rosin extender and the amount of C9 petroleum resin is used 10% ,size amount used 0.8-1.0% ,the addition levels of alum used 1.5-2% ,it can achieve good sizing effect, when use C5 ,C9 petroleum resin to be emulsified with rosin, in the experiment take the total amount of C5 ,C9 petroleum resin accounts for 10% ,20% of the total quantity of emulsified solid ,when the ratio of Cs, C9 resin is 2 to 1 ,can achieve better sizing effect. To the cationic dispersed rosin size,rosin including C5 ,C9 petroleum resin as rosin extender , when pH value reach 6.5 - 7.5, sizing performance is still good. Neutral to alkaline sizing can be achieved.%利用C5、C5石油树脂直接作为松香的补充剂与松香一起乳化制备阳离子分散松香胶,研究含有不同比例的C5、C9石油树脂的阳离子分散松香胶的稳定性和施胶作用,其中包括C5石油树脂、C9石油树脂各自的加入比例对阳离子分散松香胶稳定性的影响,两者加入不同的比例对阳离子分散松香胶稳定性的影响,含不同比例的石油树脂的阳离子分散松香胶在不同松香加入量、硫酸铝加入量和施胶PH值下的施胶性能。加入20%的C5石油树脂做松香补充剂,可以显著提高阳离子分散松香胶在PH值小于7时的施胶效率,且在施胶剂加入量1%、硫酸铝加入量2.5%下可获得理想施胶效果。加入10%的C9石油树脂做松香补充剂,可以显著提高阳离子分散松香胶在pH值小于7.5时的施胶效率,且在施胶剂加入量1%、硫酸铝加入量2%下获得理想施胶效果。
