摘要 PAGE IV SMC的发展现状及成型工艺 摘 要 模压料的选取在一定程度上决定了片状模塑料（SMC）制品的质量，选择适当的原料能满足制品的特殊性能要求，而且成型工艺也是制造模压制件的重中之重。本文首先介绍了SMC的原料组成，其中包括树脂，引发剂，低收缩添加剂，化学增稠剂，内脱模剂，着色剂以及增强材料，对于各组分的性能要求也作了简单介绍；其次分层论述了SMC的成型工艺，包括制片机组的类型和结构，SMC的生产工艺，SMC模压成型设备及工艺，而对于SMC制品存在的问题本文借鉴了几种国外改善措施，包括表面漆泡，溶剂吸入，密度大，污染环境及汽车零部件生产线的完善等等；最后对于SMC的工业应用及回收利用作了简单论述。希望大家能通过此文对SMC复合材料有一个新的认识。 关键词：SMC， 树脂， 玻璃纤维， 模压成型， 汽车部件  SMC Moulded Situation And The Development Process ABSTRACT Molding material selection to a certain extent, determine the sheet molding compound (SMC) product quality, select the appropriate raw materials to meet the performance requirements of special products, and the molding process is the priority of mould manufacturing.This article first describes the SMC feedstock composition, including resin, initiators, LPA, chemical thickeners, releasing agent, stains, and enhanced materials, for each component of performance requirements had also made a simple introduction; Secondly tiered discusses the SMC molding process, including the production unit of the type and structure of the production process of SMC, SMC molding equipment and technology, as for SMC problems this article draws on several foreign improvement measures, including the surface paint on the bubble, solvent inhalation, density, pollution of the environment and the improvement of the production line of automotive components, etc.; finally for industrial applications and recycling of SMC briefly discussed. I hope you can pass this article on the SMC composites have a new understanding.
