摘要
以丁苯胶乳为弹性粘合剂,以腈纶纤维、芳纶纤维、矿物纤维以及阔叶木纤维等为增强纤维,以硫酸铝、CPAM、膨润土体系等为助流助滤剂,制备出了非石棉纤维密封纸板.研究了硫酸铝的添加量对密封纸板助留助滤性能的影响,以及腈纶纤维的添加量对密封纸板性能的影响和机理.结果表明:硫酸铝添加量为3%时,其助留助滤效果最佳;随着腈纶纤维添加量增多,密封纸板的抗张指数增大,回弹率先增后减,在添加量为8%时达到最大,压缩率先减后增,在添加量为8%时最小,应力松弛率和热失重率增大.
Selecting styrene butadiene latex as elastic adhesive,using acrylic fiber,aramid fiber,mineral fiber and broad-leaved wood fiber as reinforced fiber,applying aluminum sulfate,CPAM and bentonite as retention and drainage agents,non-asbestos fiber sealing paperboard was prepared.The influence of aluminum sulfate amount on retention and drainage performance were studied,as well as the effect and its mechanism of acrylic fiber amount on properties of sealing paperboard.The results showed that retention and drainage performance are best when adding amount of aluminum sulfate is 3%;With adding amount of acrylic fiber increasing,the tensile index of the sealing board increases,the rebound rate increases firstly and then decreases and reaches the maximum when adding amount is 8%,the compression ratio decreases firstly and then increases and reaches the minimum when adding amount is 8%,the stress relaxation rate and heat loss rate increase.
