Abstract:In this study， xanthan gum and xanthan gum combined with inorganic or organic flame retardant were used as flame retardant coatings to prepare low ignition propensity （LIP） cigarette paper. The effects of different coatings on the flame retardancy， air permeability， smoking quality and optical properties of cigarette paper were analyzed. The results showed that when xanthan gum was used alone as flame-retardant coating with amount more than 6.4 g/m2， the automatic extinction rate of flame-retardant cigarette paper was higher than 75%， which could meet the requirements of LIP cigarette， but it had some negative influence on the appearance of cigarette. When xanthan gum-inorganic flame reactant composite coatings was used， the flame retardant effect of cigarette paper was not well， it was still difficult to meet the LIP requirements even the coating amount reached 10.0 g/m2. When xanthan gum-organic flame reactant composite coating was used， the LIP requirement could be met with the coating amount less than 4.0 g/m2， and it had no obvious influence on the appearance and smell of cigarette. The LIP cigarette paper was successfully produced in the pilot test when xanthan gum-organic flame reactant composite ratio was 1∶8 and the coating amount reached 4.5 g/m2.
