摘　　要：以氯化聚乙烯为基体材料、白炭黑或炭黑为增强材料,通过高能电子束辐照交联制备氯化聚乙烯复合材料,研究了填料用量及辐照剂量对复合材料性能的影响。结果表明,随填料用量增加,复合材料的门尼黏度显著增大,形成填料网络结构,出现明显的Payne效应。在填料用量相同时,随辐照剂量增大复合材料的拉伸强度和撕裂强度都会增大;在相同的辐照剂量下,随填料用量增多复合材料的拉伸强度先上升后有所下降。当辐照剂量为40 kGy、填料用量为40份(质量)时,氯化聚乙烯/白炭黑复合材料的拉伸强度为14.31 MPa、撕裂强度为40.6 N/mm、扯断伸长率为575%,氯化聚乙烯/炭黑复合材料的拉伸强度为16.21 MPa、撕裂强度为47.3 N/mm、扯断伸长率为579%。With chlorinated polyethylene as matrix and silica or carbon black as reinforcement fillers,chlorinated polyethylene composites were prepared by crosslinking under high-energy electron beam irradiation.The effects of filler amount and irradiation dose on the properties of the composites were investigated.The results showed that the Mooney viscosity of the composites increased significantly with the increase of filler amount,forming a filler network structure and exhibiting an obvious Payne effect.When the filler amount was the same,the tensile strength and tear strength of the composites increased with the increase of irradiation dose.Under the same irradiation dose,the tensile strength of composites increased first and then decreased when the filler amount increased.When the irradiation dose was 40 kGy and filler amount was 40 phr(by mass),the tensile strength of the chlorinated polyethylene/silica composite was 14.31 MPa,tear strength was 40.6 N/mm and elongation at break was 575%.The tensile strength of the chlorinated polyethylene/carbon black composite was 16.21 MPa,the tear strength was 47.3 N/mm,and the elongation at break was 579%.
