Abstract:In this study, the soluble starch and sodium carboxymethyl cellulose with the mass ratio of 96∶4 was used as adhesives, and the kaolin was acted as pigments. The coating materials were prepared and then used for surface coating of paper. When the mass fraction of kaolin and adhesive was 83∶17, the solid content of coating was 35%, and the coating weight was 7.5 g/m², the coated paper was rapidly carbonized after the heating device with 550 ℃ passed through the paper. The carbonization ring was not spreading, and the average diameter was 5.8 mm. At the same condition, the uncoated paper occurred smoldering, and the charring ring spread rapidly with the average pore diameter >65.0 mm. Thermal gravimetric-infrared analysis showed that the gaseous products were effectively suppressed during pyrolysis. The transition of oxygen and heat were effectively inhibited due to the spread of silicate flakes on paper surface during coating. Consequently, the paper was endowed excellent carbonization and non-diffusion performance at high temperature.
