In situ preparation, characterization and performance of magnesium carbonate whiskers/cellulose fibers hybrid paper
Source abstract
Abstract
Magnesium carbonate whiskers/cellulose fibers hybrid paper was successfully prepared via in situ synthesis process, and the flame retardancy and tensile strength properties were investigated. The effects of magnesium salt type, initial magnesium salt concentration, temperature, time and pH value were also detected. The hybrid paper was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy and thermogravimetry-derivative thermogravimetry techniques, respectively. The results showed that the same whiskers/fibers hybrid paper could be prepared from different magnesium salts. If the pH was above 9.4, hydrated basic magnesium carbonate would be created, which would lead to the decrease of oxygen index (OI). Reaction time had no effect on the OI and tensile strength of the hybrid paper. Under the optimized conditions, the OI of the hybrid paper reached 28 %. The in situ synthesis process was much better than the direct addition process.
