橡胶增塑剂通常是一类分子量较低的化合物。加入橡胶后,能够降低橡胶分子链间的作用力,使粉末状配合剂与生胶很好地浸润,从而改善混炼工艺,使配合剂分散均匀,缩短混炼时间,降低耗能,并能减小混炼过程中的生热现象,同时它能增加胶料的可塑性、流动性、黏着性,便于压延、压出和成型等工艺操作。还能改善硫化胶的某些物理机械性能,如降低硫化胶的硬度和定伸应力,赋予硫化胶较高的 Rubber plasticizers are usually a class of lower molecular weight compounds. After the rubber is added, the force between the molecular chains of the rubber can be reduced so that the powdery compounding agent and the rubbery glue can be well infiltrated so as to improve the mixing process, uniformly disperse the compounding agent, shorten the mixing time and reduce the energy consumption, and can Reduce the heat mixing phenomenon in the process, while it can increase the rubber plasticity, mobility, adhesion, ease of rolling, extrusion and molding process operations. It also improves some of the physical and mechanical properties of the vulcanizates, such as reducing the hardness and set elongation of the vulcanizates, giving the vulcanizates higher
