前言提高硫黄硫化天然硫化胶的热稳定性,希望是(ⅰ)在较高温度下,短时间硫化制品来增加生产率,(ⅱ)减少需要长时间才能使制品内部硫化的大件制品的外部硫化返原。用高比例促进剂比硫的硫化作用(有效硫化体系)比常规的高硫配方得到的网络具有更好的热稳定性。而较好的热稳定性归因于形成比较惰性比例较高的单硫
Introduction It is desirable to increase the thermal stability of sulfur vulcanized natural vulcanizates by (i) increasing the productivity of the articles at a relatively high temperature for a short period of time, and (ii) by reducing the external vulcanisation of large articles that require a long time to cure the interior of the article Back to the original. The use of a higher proportion of accelerator than sulfur vulcanization (effective curing system) has a better thermal stability than that of a conventional high-sulfur recipe. The better thermal stability is attributed to the formation of a relatively more noble ratio of monosulfur
