Abstract

Abstract: In order to analyze the thermal hazard of double-propylene latex production process and the thermal decomposition heat of its products,the test of double-propylene latex production process was carried out.An Mettler Toledo RC1e calorimeter was used to determine of exothermic characteristics during the production of double-propylene latex. A TG analyzer was applied to test the pyrolysis performance in both air and nitrogen atmospheres. The thermal hazard of the reaction process was evaluated. The thermal decomposition process of the double-propylene latex produced by the reaction was analyzed. The apparent activation energy (E_a) during thermal decomposition of the product was estimated by using the isokinetic methods (Starink method and Friedman method). The results show that the reaction thermal risk grade of the double-propylene latex production process is class 1, means it is relatively safe, that in the air condition, the thermal decomposition process of the double-propylene latex has four stages with almost no residue, that in the nitrogen condition, the thermal decomposition process of the double-propylene latex has three stages, and the residual char rate is about 9.22%, and that the E_a ranges calculated by Starink method and Friedman method are 32.65-113.45 kJ/mol and 29.70-175.90 kJ/mol respectively.

Key words: double-propylene latex, thermal hazard, thermo gravimetric(TG) analysis, thermal decomposition characteristics, apparent activation energy
