标准摘要
[中文适用范围]: 本文件描述了硫化橡胶中以下抗降解剂的测定程序: ——氨基酮基团; ——萘胺基团; ——二苯胺基团; ——对苯二胺; ——单酚基团。 表 A.1 总结了抗降解剂的类别,包括化学名称、缩写术语和 CAS 登记号。 如果存在增量油,则会产生干扰。 对于聚 2,2,4-三甲基-1,2-二氢喹啉,由于其聚合性质,该方法仅提供近似值。 [外文原描述]: This document describes a procedure for the determination of the following antidegradants in vulcanized rubbers: — aminoketone group; — naphthylamine group; — diphenylamine group; — p-phenylenediamine; — monophenol group. The groups of antidegradants are summarized in Table A.1 with the chemical names, the abbreviated terms and the CAS registry numbers. Extender oils, when present, can interfere. For poly-2,2,4-trimethyl-1,2-dihydroquinoline, the method provides only an approximation because of its polymeric nature.
