Industry-University Cooperative Research: A Basic Study of Injection Molding of Rubber Compound

本研究旨在为胶料注射成型这一本质上经验性的技术奠定科学基础。这项研究涉及多个工程学科的条件，包括聚合物流变学、反应工程、流体力学、传热学和聚合物科学。具体任务包括：通过测量固体表面的流变学和热学性质、硫化动力学和滑移边界条件来定量表征橡胶化合物；螺杆、输送系统和空腔中流动动力学的实验和理论研究，包括后填充阶段；描述注塑部件收缩和冻结取向和残余应力的实验测量和定量理论的发展；以及工艺条件和胶料性质对注塑件力学性能各向异性影响的实验研究。

This research is directed to develop the science-base of the essentially empirical technology of injectio molding of rubber compounds. The research involves the condition of various engineering disciplines including polymer rheology, reaction engineering, fluid mechanics, heat transfer, and polymer science. The specific tasks will include: quantitative characterization of the rubber compound by measurements of rhelogical and thermal properties, valcanization kinetics and slip boundary conditions at the solid surface; experimental and theoretical investigations of flow dynamics in the screw, the delivery system, and cavity including the postfilling stage; experimental measurements and development of wuantitative theory for characterizing the shrinkage in molded parts and frozen-in orientation and residual stresses; and experimental sutudy of anisotropy of mechanical properties of molded parts effected by processing condition and the nature of the rubber compound.
