ACR与CaCO3协同作用对PVC管材拉伸性能的研究

摘要

CaCO3, ACR, CaCO3 and ACR blends on the tensile properties of PVCdrainage pipe. When the CaCO3 in an amount up to 20 parts and the ACR amount of 5 parts, The results showed that: the tensile strength is about 40MPa,the elongation at break reaches 120%.%分别研究了CaCO3、ACR、CaCO3与ACR共混体对PVC排水管材的拉伸性能的影响。CaCO3的用量达到20％、用量5％时，当ACR管材的拉伸强度为40MPa，断裂仲长率为120％。
