METHOD OF IRRADIATION-INDUCED VULCANIZATION OF NATURAL RUBBER LATEX

摘要

PURPOSE:To conduct the irradiation-induced vulcanization of a natural rubber latex economically and safety without increasing the viscosity by mixing the latex with a hydroperoxide and then with a gamma-butyl acrylate, and irradiating the resulting mixture with an ionizing radiation. CONSTITUTION:100 pts.wt. (solid rubber base) natural rubber latex is mixed with 0.05-2 pts.wt. hydroperoxide (e.g. t-butyl hydroperoxide) and then with 0.5-10 pts.wt. gamma-butyl acrylate, and the mixture is stirred for at least 30min and left standing for 10-24hr to dissolve the acrylate homogeneously. The latex is irradiated with an ionizing radiation at a dose of 1-30KGy.
