摘要
以无纺纸作为基底材料,通过在聚氯乙烯糊树脂中添加无机阻燃剂与阻燃型增塑剂的方法,制备出无纺纸基/聚氯乙烯壁纸,并研究其阻燃性、热稳定性、消烟性和力学性能。结果表明,无机阻燃剂2Zn O·3B2O3·3.5H2O可提高无纺纸基/聚氯乙烯壁纸的阻燃性和热稳定性,增塑剂磷酸三甲苯酯可辅助提高材料的阻燃效果;以无纺纸为基材,以2Zn O·3B2O3·3.5H2O为无机阻燃剂,以磷酸三甲苯酯为增塑剂,可制备出具有高阻燃性、高消烟性和高力学性能的无纺纸基/聚氯乙烯壁纸;材料在阻燃改性后的极限氧指数可达32.5,比改性前提高了51.2%;最大烟密度为11.8%,比改性前降低了21.9%;横、纵向湿抗张强度分别达到1.20和1.23 k N·m-1,比改性前提高了6.2%和7.0%。改性后的材料满足国家标准GB 8624-2012中B1级材料的阻燃要求。研究结果可为制备阻燃型的无纺纸基/聚氯乙烯壁纸开辟一条有效的途径。
The flame-retarded non-woven paper based polyvinyl chloride（ PVC） wallcoverings were successfully prepared,using non-woven paper as base material and adding inorganic flame retardants and flame-retarded plasticizer as additives. Flame retardancy,thermo stability,smoke suppression and mechanical properties were tested regarding to the prepared wallcoverings. The results showed that 2Zn O·3B2O3·3.5H2 O could improve flame retardancy and thermo stability of non-woven paper based PVC wallcoverings; plasticizer tricresyl phosphate increased flame retardancy of the prepared materials auxiliarily. Also,flame-retarded non-woven paper-based PVC wallcoverings with higher flame retardancy,greater smoke suppression and stronger mechanical property was prepared using non-woven paper as base material,using 2Zn O·3B2O3·3.5H2 O as inorganic flame retardant,and using tricresyl phosphate as plasticizer. For the flame-retarded non-woven paper based PVC wallcoverings,the limit oxygen index reached 32.5 and increased by 51.2%,maximal smoke density was 11.8% and decreased by 21.9%,and the horizontal and longitudinal wet tensile strength reached 1.20 and 1.23 k N·m-1and increased by 6.2% and 7.0% respectively. Meanwhile,its flame retardancy satisfied the requirements about flame retardancy for material Class B1 listed in Chinese National Standards GB 8624-2012. This research created an effective path to prepare non-woven paper based PVC wallcoverings with high flame retardancy.
