摘要: 采用廉价及可再生的脂松香、椰子油酸、棕榈酸为原料,制备生物基脱墨剂,并应用于废纸脱墨。采用FT-IR对原料进行了表征,以正交试验法优化了生物基脱墨剂的制备工艺,探讨了生物基脱墨剂的最佳用量及脱墨性能,并与传统脱墨剂做脱墨性能对比。FT-IR结果表明,生物质原料中既有饱和的脂肪酸也有不饱和的脂肪酸。生物基脱墨剂优化的制备条件为时间30min、温度90℃、m(脂松香):m(椰子油酸):m(棕榈酸)为2.5:3.5:4.0、NaOH溶液的质量分数40%。生物基脱墨剂是一种高效脱墨剂,最适加入量为0.20%;在加入量为0.20%,浮选温度为40℃,浮选时纸浆质量分数1.0%,浮选pH值为9,浮选时间为20min时,脱墨后废纸浆白度可达58.67%(ISO),残余油墨值达274.42mm2/m2,油墨去除率达57.81%;实际应用结果表明生物基脱墨剂的脱墨性能优于传统的S型和天小脱墨剂。

Abstract: The biomass based deinking agent was prepared by using cheap and renewable coconut fatty acid,palmitic acid and gum rosin as raw materials. The raw materials were characterized by FT-IR;the technology of preparation was optimized;the optimum addition amount of deinking agent and the deinking properties were discussed. The deinking properties were also compared with the traditional deinking agents. The FT-IR results showed that the raw materials were both saturated fatty acids and unsaturated fatty acids,and the optimized preparation conditions of biomass deinking agent were 30min,90℃,m(gum rosin):m(coconut fatty acid):m(palmitic acid) of 2.5:3.5:4.0,NaOH mass fraction of 40%. The obtained biomass based deinking agent was a kind of high efficient deinking agent,and the optimum addition amount was 0.2%. After deinking under the addition amount 0.2%,40℃,the mass fraction of pulp 1.0% and pH value 9 for 20min,the brightness of deinking pulp was 58.67%(ISO),the residual ink concentration was 274.42mm2/m2,and the removal rate of ink was 57.81%. Practical application results showed that the deinking effect of biomass based deinking was superior to that of the traditional type S and tian xiao deinking agents.
