研究蛋白质含量为0.5%～2.7%的天然橡胶（NR）生胶的理化性能、硫化胶的物理性能、耐热老化性能、永久变形性能和压缩生热。结果表明：不同蛋白质含量的NR生胶的理化性能基本相同；随着蛋白质含量降低，NR硫化胶的定伸应力、拉伸强度和撕裂强度呈先升后降的趋势，压缩永久变形减小，压缩生热降低，蛋白质含量低于1%时耐热老化性能明显降低。蛋白质含量在1.0%左右NR硫化胶的综合性能最好。

The physicochemical properties of NR with the protein content of 0.5% to 2.7% was studied, and the physical properties, heat aging properties, permanent set and compression heat buildup property of the vulcanizates were investigated. The results showed that the physicochemical characteristics of the raw rubber with different protein content were basically the same. With the decrease of the protein content, the modulus, tensile strength and tear strength increased ifrst and then decreased, the permanent set decreased and the heat buildup was reduced. The heat aging resistance of the NR with the protein content less than 1%decreased signiifcantly. The vulcanizates with protein content of about 1.0%showed the best overall properties.
