| Abstract: |
| 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. |
