Carbonization Treatment of Diatomite with High Ignition Loss and Reinforcement of Natural Rubber
摘要
Abstract
A carbonized diatomite was prepared by calcining Inner Mongolia diatomite rich in organic matter under reducing atmosphere. The carbonized diatomite was partly substituted for carbon black to reinforce natural rubber(NR). Fourier-transform infrared spectra ( FTIR) , X-ray diffraction ( XRD ) , thermoanalysis (TG-DTA) , scanning electron microscope ( SEM) , energy-dispersive spectrometer ( EDS ) and mechanical properties test were employed to characterize the resultant carbonized diatomite and NR vulcanizates. The results showed that the organic matter in diatomite could be translated into amorphous carbon adsorbed on the surface of diatomite and in the micropore of diatomite after 600 ℃ calcination under reducing atmosphere. Because the carbon in carbonized diatomite could improve the compatibility between diatomite and NR, the introduction of carbonized diatomite into NR matrix could enhance the mechanical properties. When 25% (mass fraction) carbon black was replaced by carbonized diatomite, the tensile strength and tear-strength of NR vulcanizates were significantly improved.关键词
