PRETREATMENT OF NATURAL RUBBER LATEX FOR RADIATION VULCANIZATION

摘要

PURPOSE:To carry out vulcanization with small radiation dose in vulcanizing natural rubber latex by radiation by using 2-ethylhexyl acrylate and carbon tetrachloride as a promoter, by adding hydrophilic and liquid hydroperoxide. CONSTITUTION:A 100 pts.wt. rubber solid content of natural rubber latex is blended with preferably 1-5 pts.wt. 2-ethylhexyl acrylate, preferably 1-2 pts.wt. carbon tetrachloride and preferably 0.1-0.5 pt.wt. hydrophilic and liquid hydroperoxide (preferably t-butyl-hydroperoxide), stirred preferably for =30 minutes, allowed to stand for 15-30 hours and irradiated with preferably 5-20kGy radioactive radiation to vulcanize natural rubber.
