摘　　要：实验探讨了以十溴二苯乙烷为主体的溴-锑协同阻燃体系中溴-锑元素质量比对空气过滤纸阻燃效果的影响,结果表明,二者最适质量比为3∶1。在此比例下,进一步研究了阻燃剂用量对空气过滤纸阻燃性能、力学性能以及透气性的影响,结果显示,阻燃剂留着率为25%时,阻燃性能达到GB/T14656—1993要求,此时挺度提高了约20%,但耐破度和透气度分别下降了约11%和10%。In order to improve the flame-retardant properties of air filter paper for internal combustion engine, the effect of mass ratios of bromine and antimony in bromide-antimonite synergistic flame retardant system on fire-retardant performance of air filter paper was studied. The results showed that the optimal mass ratio of the two was 3：1. On this condition, the effect of the dosage of flame retarder on flame-retardant property, mechanical properties and permeability was further investigated. The results showed that the flame-retardant property satisfied the requirement of the standard GB/T14656--1993 when the retention rate of flame retarder was 25%. Meanwhile the paper stiffness increased by 20% , and bursting strength and permeability were reduced by 11% and 10% respectively.
