| 研究新型高效复合促进剂EA97在EPDM胶料中的应用，并与国外同类产品EG-3进行对比。结果表明：在EPDM4045和EPDM511胶料中，与加入促进剂EG-3相比，加入促进剂EA97的胶料MH略有增大，t10和t90缩短，硫化胶的300%定伸应力增大，拉断伸长率和拉断永久变形减小；加入促进剂EA97和EG-3的硫化胶经室温停放60 d后均未出现喷霜现象。促进剂EA97在EPDM4045胶料中的t10和t90均比在EPDM511胶料中有所缩短。在硫黄合理用量范围内，EPDM4045/EPDM511并用胶（并用比50/50）的300%定伸应力、拉伸强度、拉断伸长率和拉断永久变形的变化主要取决于促进剂EA97的用量，而硫黄用量的影响相对较小。 |

| The adhesion property at normal and high temperature of heat resistant conveyor belt of duck construction and its affecting factors were investigated.The results showed that,with increase of experiment temperature, the adhesion property of heat resistant conveyor belt of duck construction decreased significantly. By adding adhesive RF/RA with the blending ratio of 4/3.6 in cover compound，the adhesion property of belt at normal and high temperature increased.The adhesion property at normal temperature could also be improved by increasing the thickness of breaker ply properly,but the adhesion property at high temperature changed little.At high temperature,the adhesion property of belt with nylon 6 canvas was better than that with polyester canvas. |
