Abstract：To solve the problem of permeability about flame retardant, the APP/kaolin composite was synthesized system using silicone oil as the modifier. The enchanted mechanism was discussed by contact angle and FTIR analysis. The results show that the optimal proportion and the optimal modification conditions are obtained as follows: 30% of the mass fraction of kaolin, 2% of the modifier dosage, and 80 ℃ of the temperature.After the modification, the permeability resistance of the obtained product increase significantly, and the bleeding rate is reduced from 1.81% to 0.61%.
