Study on radiation vulcanization of natural rubgber latex

摘要

The effect of dose rate of ~60Co γ-ray on radiation vulacnization of natural rubber latex is studied using Malaysian latex with 0.002 mass fraction KOH and 0.05 mass fraction n-BA. Results show that, when radiation doses are 20 and 15 kGy, only that the dose rates are greater than 0.49 and 1.6 kGy/h, respectively can make the tensile strength of latex film meet the related standard; besides, storage time of radiation vulcanization latex has no effect on physical properties of the film.
