研究了以高压聚乙烯 (LDPE)改性NR的橡塑共混物的生产工艺配方。试验结果表明 ,LDPE用量以 1 5～ 2 5份为最佳 ,可采用硫黄硫化体系 ,促进剂选用TMTD/DM效果最好 ,并可采用母炼胶共混、控制NR塑性值、强化混炼等方法提高共混物的混合均匀性。最终得到兼具橡胶和塑料性能的共混物 ,并在实际生产中得到较好运用。
The production process of rubber-plastic blends modified with high-pressure polyethylene (LDPE) NR was studied. The test results show that the optimal dosage of LDPE is 15 ~ 25, sulfur vulcanization system can be used, TMTD / DM is the best accelerator, and the masterbatch can be used to control the NR plasticity and strengthen the mixing Other methods to improve the mixing uniformity of the blend. Finally get both rubber and plastic properties of the blend, and in the actual production has been better use.
