燃气管用抗静电聚乙烯复合材料的制备及性能研究

摘要

通过将十四烷基甲基二羟乙基溴化铵( TMDAB )、甜菜碱和导电炭黑复配，得到高效持久的复合抗静电剂，利用其对聚乙烯进行改性，从而研制出新型抗静电聚乙烯复合材料，进一步开发出新型抗静电聚乙烯管材，消除静电带来的安全隐患，扩大其在燃气管领域的应用。%Antistatic agent composed of tetradecyl methyl dihydroxyethyl ammonium bromide( TMDAB) ,betaine and graphitized carbon black were used to modify polyethylene in this article. Thus,a new type of antistatic polyeth-ylene composite material was developed. Further, a new type of antistatic polyethylene pipe can be developed to eliminate the safety hazards caused by static electricity,broadening its application in gas area.
