摘要： 运用顶空-气质联用法测定20NR、80NR的乳胶海绵在不同温度下以及燃烧后残渣在固定温度下挥发性气体成分，并对其产生规律进行分析。加热炉设定温度50、80、120、120 ℃，加热时间为30 min。结果表明：80 ℃时天然乳胶含量为80NR的乳胶海绵产生的挥发性气体种类比20NR的多。120 ℃时，虽然挥发性气体种类数量相同，但80NR的挥发性气体更为复杂。同种天然乳胶含量的乳胶海绵产生的挥发性气体种类会随着温度的增加而增加。除乳胶80NR在50 ℃时未检测到Si大于90的化合物，其他均能检测到二硫化碳、正十一烷、十二碳烷这三类有一定毒性的挥发性气体。

Abstract: Volatile gas components of 20NR and 80NR latex sponges at different temperatures and the residue after combustion at certain temperature were tested by headspace GC-MS,and its production law was analyzed.The setting temperature of the heating furnace was 50, 80, 120 and 120 ℃, and the heating time was 30 min. The results showed that volatile gas of 80NR latex sponge is more in kinds than that of 20NR latex sponge at 80 ℃. Although the volatile gases are the same in number of kinds at 120 ℃, the volatile gases of 80NR are more complex. The kinds of volatile gases produced by latex sponge with the same natural latex content will increase with the increase of temperature. No compound with Si greater than 90 was detected for 80NR latex sponge at 50 ℃, but carbon disulfide, n-undecanone and dodecane can be detected as three kinds of toxic volatile gases in other tests.
