It studied the relation between the use amount of cocuring agent and softening agent, preparation processes of different single-screw extruders and the properties of EPDM/ PP by means of peroxide vulcanization system. 采用过氧化物硫化体系,研究了助硫化剂种类、软化剂用量及不同单螺杆挤出机制备工艺与EPDM/PP(TPV)性能的关系。
Differences between Thermal-Oxidative Stability of Medical Natural Rubber Latex Products Prepared by Peroxide Pre-vulcanization and Sulfur vulcanization 过氧化物预硫化与硫黄硫化制备的医用天然胶乳制品热氧稳定性的差异
The results showed that the compound needed to use peroxide vulcanization system and aid cross-linker with high temperature cure and secondary cure process. 结果表明,胶料需采用过氧化物硫化体系和助交联剂,用高温硫化和二次硫化工艺。
The results showed that the gel fraction of LLDPE/ POE blends increased with the content of dicumyl peroxide ( DCP)、 vulcanization time and the incremental of crosslinking time and reached maximum at a certain value. 结果表明,LLDPE/POE共混物的凝胶含量随引发剂的用量、交联温度和交联时间的增加而增加,达到一定程度后不再增加。
