摘　　要：对湿法白炭黑天然橡胶(NR)母胶(简称湿法母胶)进行理化分析,并将其应用于NR基本配方以及全钢载重子午线轮胎的胎面胶、基部胶和带束层胶配方中进行性能测试。结果表明:湿法母胶的灰分质量分数达到指标要求;在NR基本配方以及高速胎面胶、矿山胎面胶、基部胶和带束层胶配方中,湿法母胶的胶料性能与干法加入白炭黑的胶料基本相当,可以满足全钢载重子午线轮胎配方的使用要求。The physico-chemical property of wet silica NR masterbatch （ wet masterbatch in brief ） was analyzed in this study. The wet masterbatch was applied in the standard NR formulation compound, tread compound, tread base compound and belt compound of all steel truck and bus radial tire, and the properties of those compounds were tested. The results showed that, the ash content of wet masterbatch met the requirements specification. The property of the wet masterbatch compound was equal to that of the compound prepared by adding silica directly. The properties of high speed tire tread compound, mining tire tread compound, tread base compound and belt compound with the wet masterbatch all met the application requirements of all steel truck and bus radial tire.
