| 摘 要： | 分别研究了纳米CaCO3粉体与纳米CaCO3母料作为改性剂,对UPVC型材性能的影响。结果表明:填充8份纳米CaCO3粉体的UPVC型材拉伸强度与冲击强度都显著提高。纳米CaCO3母料填充体系力学性能要比粉体直接填充的低,但冲击强度在高填充时保持稳定,挤出扭矩较低,并初步推导了机理。

| Abstract: | It studied the influencing effects of nano-CaCO_3 powder and nano-CaCO_3 masterbatch, both of which are to be modifiers, on the properties of unplasticized polyvinyl chloride (UPVC) profile. The results showed that the tensile strength and the impact strength of UPVC profile with the addition of 8pph nano-CaCO_3 are improved. The mechanical properties of UPVC profile filled with nano-CaCO_3 masterbatch is lower than those of UPVC filled with nano-CaCO_3 powder, but the impact strength is kept steady and the extrusion torque is lower at the high filling amount of nano-CaCO_3. It also related to the influencing mechanism on properties of composite. |
