摘　　要：对建筑用PVC塑料管材进行人工耐候老化测试,得到几组老化后的拉伸强度、断裂伸长率、弯曲强度、弯曲弹性模量和简支梁缺口冲击强度等数据,通过结果分析讨论,得到采用配方1加工生产的建筑塑料管材,其强度性能随着老化时间的增加出现先升高然后再降低的趋势。Based on the building with PVC plastic pipe to artificial weathering aging test, several groups of data were obtained after aging, tensile strength, tensile strain at break, flexural strength, modulus of elasticity in flexure and charpy notched impact strength, the results were analyzed and discussed, and the conclusion was got by Formula 1, its strength properties along with the increase of the aging time increased at first and then decreased.
