摘　　要：应用250keV低能电子束循环辐射硫化二丙烯酸壬酯(1,9-nonanedilodiacrylate,NDDA)敏化的天然橡胶乳液,探讨了影响低能电子束循环辐射硫化天然橡胶乳液的因素。结果表明,提高电子束束流,可缩短辐射硫化时间;40%的天然橡胶乳液更适合低能电子束的辐射硫化;适当提高循环乳液的重量有利于辐射硫化乳液的质量控制。The circulating radiation vulcanization of natural rubber latex （RVNRL） has been carried out with 250 keV electrons in the presence of sensitizer like NDDA （1, 9-nonanedilo diacrylate）. The irradiation time decreases with increasing beam current. 40 % natural rubber latex is suitable for radiation vulcanization with low energy electron beam. It is beneficial to quality control of RVNRL to use adequately increased weight of the natural rubber latex.
