Abstract
Novel mixed antioxidants composed of antioxidant IPPD and lanthanum (La) complex were added as a filler to form natural rubber (NR) composites. By mechanical testing, Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) and thermogravimetric analysis (TGA), a string of data, including the mechanical properties, the variation of internal groups and the thermal and thermo-oxidative decompositions of NR, was presented in this data article. The data accompanying its research article [1] studied the thermo-oxidative aging properties of NR in detail. The density function theoretical (DFT) calculations were also used as an assistant to study the thermo-oxidative aging mechanism of NR. The data revealed that this new rare-earth antioxidant could indeed enhance the thermo-oxidative aging resistance of NR, which is associated with its different function mechanism from that of the pure antioxidant IPPD.

Summary
Spectra, table An electronic tensile machine (Shenzhen SANS Test Machine Co., Ltd., China); FTIR-ATR (a Nicolet 8700 FTIR spectrometer, Thermo Fisher Scientific Inc., USA); TGA (a TGA/Differential Scanning Calorimetry (DSC) calorimeter, Mettler-Toledo Co., Switzerland); Gaussian 09 suit of program Raw, analyzed After being mixed on a two-roll mill, the compounds were cured in a 25 T hot compression mold at 143 °C for t90 to gain NR composites. These data provides a complete set of methods for other scientists to study the thermo-oxidative aging properties of materials. These data proposes a theoretical method for investigating the function mechanism of different antioxidants. These data has important significance for the exploitation of rubbers with high resistance to thermo-oxidative aging. Data presented in this article was used to investigate the different protective effects on the thermo-oxidative aging properties of two formulations of NR – one with the antioxidant IPPD and the other with the mixed antioxidants composed of antioxidant IPPD and lanthanum (La) complex. The data about theoretical calculations was used as an assistant to investigate the different function mechanisms of the antioxidant IPPD and La complex
