Abstract Concentrated natural latex is an important raw material for preparing natural latex products. Ammonium laurate is added as a stabilizer during storage to improve the stability of latex. Ammonium laurate plays a significant effect on the storage stability of concentrated latex and its vulcanization properties, which affects the performance of its products in turn. This paper analyzes the changes in the mechanical stability (MST) and volatile fatty acid (VFA) values of concentrated latex during storage, and the crosslinking density, mechanical properties and thermal stability of the vulcanized rubber film were tested and characterized. The effect of ammonium laurate on the storage stability of concentrated latex and the properties of vulcanized rubber was studied. The results were shown that the absolute value of the Zeta potential of the concentrated latex significantly increases after adding ammonium laurate, the particle size of the latex becomes smaller, and the stability of the latex was enhanced. When the ammonium laurate was added in an amount of 0.050% —0.075%, the mechanical stability of the concentrated latex had been significantly improved. The minimum storage time required for the MST value to reach the national standard was 20 days; the ammonium laurate had caused the vulcanization rate of the concentrated latex to decrease. At the same prevulcanization time, the crosslinked density of the vulcanized rubber with concentrated ammonium laurate was lower, and the mechanical properties and thermal properties of the vulcanized rubber film was decreased accordingly.

Key words： concentrated latex ammonium laurate storage stability vulcanizate performance
