Abstract
Organic flame retardant of N-P complex type and inorganic flame retardant hydrotalcite were respectively added to waterproof breathable coating agent ,the influence of dosages of two fla- me retardants on the flame retardancy of coated fabric were studied ,and the influence of the optim- al dosages of different flame retardants on the waterproof breathable permeability of coated fabric were investigated . The results show that adding inorganic flame retardant hydrotalcite has better flame-retardant and waterproof breathable permeability when the addition of hydrotalcite is 5% quality of coating agent , after-flame time and after-glow time of coated fabric are 0s, char length is 10.5cm, moisture quantity is 7247g/m2•24h, water pressure resistance is 430mmH2O.
