DEVICE FOR TESTING THERMAL OXIDATION AGING KINETICS, AND METHOD FOR TESTING THERMAL OXIDATION ABSORPTION CURVE

摘要

Provided are a device for testing the thermal oxidation aging kinetics of rubber, and a method for testing a thermal oxidation absorption curve; the testing device comprises a test bench (1), an evacuation and oxygen-supply system (7), a temperature control system (8), an oxygenation system (9), and an automatic recording system (10); the test bench (1) is an integrated structure; test chambers (2) are arranged symmetrically inside the test bench; the center and edge positions of the test bench (1) are provided with a center temperature measurement sensor (6) and an edge temperature measurement sensor (6'), respectively; the periphery of the test bench (1) is provided with, in sequence, a heating band (3) and a thermal layer (5); a sealed end of the test chambers (2) is provided with a pressure sensor; the test chambers (2) are separately in communication with the evacuation and oxygen-supply system (7) and the oxygenation system (9); the heating band (3) is connected to the temperature control system (8); the oxygenation system (9) is connected to the automatic recording system (10). The device of the present invention can be used for accurate, rapid, and bulk testing of the thermal oxidation properties of rubber.
