有机过氧化物DCP/硫黄并用硫化体系在轮胎胎侧胶中的应用

Application of Organic Peroxide DCP/Sulfur Curing System in Sidewall Compound of Tire

研究有机过氧化物DCP/硫黄并用硫化体系在轮胎胎侧胶中的应用。结果表明:与硫黄硫化的胶料相比,有机过氧化物DCP/硫黄并用硫化体系硫化的胶料的门尼焦烧时间缩短,硫化速度减慢,但F_(max)增大,抗硫化返原性提高;硫化胶的硬度、定伸应力、拉伸强度和撕裂强度增大,耐热老化性能和耐臭氧老化性能提高,耐屈挠性能相当。

The application of organic peroxide DCP/sulfur curing system in the sidewall compound of tire was studied.The results showed that compared with sulfur vulcanized compound,the Mooney scorch time of the compound vulcanized with organic peroxide DCP/sulfur curing system was shortened,the curing speed was slowed down,but the F_(max) increased,and the anti-reversion property was improved.In addition,the hardness,modulus,tensile strength and tear strength of the vulcanizate increased,the heat aging resistance and ozone aging resistance were improved,and the flexure resistance was equivalent.
