研究国产脱蛋白天然橡胶（DPNR）的性能及其在减震橡胶制品中的应用。结果表明：与普通天然橡胶（NR）相比，DPNR的氮含量较小，压缩生热较低，压缩永久变形较小，弹性和电绝缘性能较好，拉伸强度和拉断伸长率略低，耐老化性能稍差；用国产DPNR为主体材料试制的机车弹性旁承的强化疲劳性能、尺寸稳定性和弹性好，压缩永久变形小。

The properties of domestic deproteinized natural rubber (DPNR) were studied, and its application in damping rubber products was investigated. The results showed that, compared with ordinary natural rubber (NR), the nitrogen content of DPNR was lower, the heat build-up in dynamic compression test was less, the compression set was smaller, the flexibility and electrical insulation properties were better, but the tensile strength and elongation at break were slightly lower, and the aging resistance was slightly lower. The rubber side bearing for locomotive by using domestic DPNR as the main material possessed good dynamic properties, enhanced fatigue resistance, excellent dimension stability, good elasticity, low heat build-up, low creep and small compression set.
