| 中文摘要: |
| 研究蛋白质质量分数为0.000 6～0.005 0的脱蛋白天然橡胶（LPNR）的性能及其在轮胎胎肩垫胶中的应用。结果表明：随着蛋白质含量的降低，LPNR生胶的塑性初值、塑性保持率和门尼粘度下降，硫化胶的拉伸强度和拉断伸长率提高；采用LPNR的胎肩垫胶的定伸应力、撕裂强度、硬度、压缩生热和损耗因子降低，拉伸强度、拉断伸长率、耐屈挠性能和弹性明显提高；蛋白质质量分数为0.002 5的LPNR胶料综合性能最优，适合用于胎肩垫胶。 |
| 英文摘要: |
| The properties of deproteinzed natural rubber（LPNR） which protein mass fraction was between 0.000 6 and 0.005 0，as well as it is application in tire shoulder pads were studied.The results showed that with the protein content decreased，the initial plasticity，plasticity retention index and Mooney viscosity of LPNR raw rubber were desceased，the tensile strength and elongation at break were increased.The modulus，tear strength，hardness，compression heat build-up and tanδ of shoulder pad with LPNR were decreased，but tensile strength，tensile elongation，flex resistance and elastic resilience were all obviously improved.The comprehensive properties of LPNR in which protein mass fraction was 0.002 5 was the best and suitable for using in shoulder pads. |
