| Abstract:To explore the effects of new flame retardants （LD and APP） on flame retardancy of cigarette paper with low ignition propensity （LIP）. Flame retardants LD， APP and their mixture were used to prepare the coatings respectively， which were used to product low ignition tendency cigarette sheet sample by using coating process. The properties of smoldering rate， full-length combustion ratio and diffusivity of retardant zone of the cigarettes prepared with the sheet sample were analyzed. The test results showed that when the flame retardant LD or APP was used alone， both of them had flame retardant property. Flame retardant LD had better flame retardant performance than flame retardant APP， but when flame retardant LD was used alone for coating， there existed boundary diffusion penetration phenomenon in the flame retardant zone, and with the increase of LD dosage， the flame retardant LD on the flame retardant band was prone to drop off powder. The problems existing in the use of flame retardant LD alone， could be solved by using the combination of flame retardants LD and APP. When the content of flame retardants LD and APP reached about 16%, full-length combustion ratio was 20%， and diffusivity was about 1.000 cm/s， the performance of LIP cigarette paper could meet the requirements. |
