| 中文摘要: |
| 以羧基丁腈胶乳（XNBRL）检查手套的实用配方为基础，考察硫化体系和两段硫化工艺对XNBRL胶膜拉伸性能和交联密度的影响。结果表明：在硫黄硫化体系中以促进剂TMTD等量替代促进剂ZDBC和适当增大氧化锌用量，均能增大XNBRL胶膜的交联密度和强度；适当延长110 ℃下硫化时间，有利于提高XNBRL胶膜的交联密度和强度，XNBRL胶膜合适的硫化工艺条件为110 ℃×45 min＋120 ℃×30 min。 |
| 英文摘要: |
| The effects of vulcanization system and curing process on the tensile property and crosslinking degree of carboxylated nitrile butadiene rubber latex（XNBRL） film were investigated based on the production formulation of XNBRL inspection gloves. The results showed that，using equal amount of accelerator TMTD to replace accelerator ZDBC in the sulfur vulcanization system and increasing the amount of zinc oxide，the crosslinking density and strength of XNBRL film increased. Properly extending the curing time at 110 ℃ was beneficial to increasing the crosslink density and strength of XNBRL film，and the suitable curing process condition was 110 ℃× 45 min＋120 ℃× 30 min. |
