摘要

The thioacetamide derivative composite preservation system significantly enhances the vulcanization efficiency and mechanical properties of NR latex. Compared to 2-imidazolidinethione and 3-hydroxypyridine

it demonstrates superior performance in promoting crosslinking density and mechanical strength

suggesting that the thioamide and pyridine groups work synergistically to facilitate the vulcanization of NR.

Abstract

The thioacetamide derivative (TD)-composite preservation system (TDCPS) exhibits superior preservation effects on natural rubber latex (NRL) and significantly enhances its vulcanization efficiency and mechanical properties. This study primarily investigated the principal chemical groups and mechanism of action of TDCPS in promoting NRL vulcanization through a comparative analysis. The results indicated that the key functional groups (thioamide and pyridine) in TDCPS synergistically accelerated crosslinking

reducing the vulcanization time by 41.18% compared to the high-ammonia (HA) preservation system. At an optimal TDCPS dosage of 5 mmol·L

–1

vulcanized films achieved a tensile strength of 34.18 MPa

with a sulfur content of 1.5 phr further improving the strength by 42.26%. TD outperformed the conventional accelerators 2-imidazolidinet

hione (ETU) and 3-hydroxypyridine (3-Hp) in promoting the crosslinking density and mechanical performance while eliminating ammonia-related environmental risks. This eco-friendly system demonstrates the industrial potential for sustainable rubber production.
