摘要
本文以己内酰胺为原料,采用间歇法对矿用浇注(MC)尼龙单根支柱柱鞋的制备工艺进行了研究。结果表明,主反应物己内酰胺分子的活化速度主要由OH—(碱性催化剂)浓度决定,其合适浓度范围为0.1-1mol/L。研究还发现,虽然增大助催化剂的用量能增加反应速度,但制品的机械强度会随之下降。同时研究了抗静电剂和无机阻燃剂对制品的耐压性能、抗静电性能和阻燃性能的影响,结果表明,在一定范围内抗静电剂和无机阻燃剂对制品的抗静电和阻燃性能影响不大,但制品的耐压性能有所下降。基于以上的研究,在基本辅料保持不变的情况下,我们提出了Φ260、Φ280、Φ300矿用柱鞋的适用配方。
The preparation crafts of monomer casting (MC) nylon shoes of individual strut with caprolactam as the raw material were investigated by intermittent type method in this experiment. The results indicated that the activated rate of caprolactam molecular was determined by concentration of hydroxyl ion, and the suitable concentration range of alkaline catalyst was usually about 0.1-1mol/L. In addition, the reaction rate would raise with the increasing of assistant catalyst amount, but the mechanical properties of the product would decrease. Meanwhile, the pressure resistant performance, antistatic property and fire retardant property of the product were also studied. Antistatic and fire retardant properties could be both maintained with the increase of antistatic agent and inorganic flame retardant agents, but the pressure resistant performance decreased somewhat. Based on the above research, the optimum formula of Ф260, Ф280, Ф300 for perparation MC nylon shoes of individual strut were proposed while the essential assistant materials remain the same.
