3种牌号IIR在力车轮胎内胎中的应用

Application of different brands of IIR in inner tube of cart tire

对国产IIR 175 1、俄罗斯ΒΚ 1675N、日本JSR2 68三种牌号的IIR在力车轮胎内胎中的应用进行了研究。结果表明 ,3种牌号IIR内胎胶料的门尼粘度、硫化特性和工艺性能相近 ,硫化胶老化前和老化后 ( 12 0℃× 48h)的物理性能差异不大 ,成品内胎的物理性能和耐久性能均达到国家标准。 3种牌号的IIR均可用于力车轮胎内胎的生产 ,但IIR 175 1价格低 ,货源稳定 。

The application of three brands of IIR,i.e.IIR 1751 from China,Β? ?675N from Russsia and JSR268 from Japan in the inner tube of cart tire was investigated.The results showed that the Mooney viscosity,processibility and curing behaviour of all three IIR inner tube compounds were similar;there were little differences in physical properties among their original and aged (120 ℃×48 h) vulcanizates;and the physical properties and endurance of all finished inner tube met the requirements in the relevant national standards.All three brands of IIR were suitable to make the inner tube of cart tire,but IIR 1751 was more competitive because of its lower price and higher availability.
