【摘要】 介绍了水悬浮法制备连续玻璃纤维针刺毡增强PVC复合材料(PVC/GMT)的成型工艺。讨论了材料成型过程中的工艺设计的要点。针对硬质PVC难加工的特点,选用了ACR-401作为加工过程中的流动改性剂,并且讨论了ACR-401流动改性剂的含量对PVC/GMT材料力学性能的影响。同时研究了不同玻璃纤维含量对PVC/GMT材料力学性能的影响。更多还原

【Abstract】 In this article, the process of snitched continuous glass fiber mat reinforced PVC composites by aqueous suspension is studied.And the technology design points in material process are also studied. Aiming at the difficulty for PVC in the process,the ACR-401 is chosed as flowing modifier and the influences of flowing modifier ACR-401 content and GF content on PVC/GMT material mechanical properties are discussed.更多还原
