Abstract
The flame retardant according to the present invention is prepared by complexing a flame retardant polyphosphate compound with a silicone resin. The silicone resin is applied to cover the particles of the polyphosphate compound. As the polyphosphate compound, it is preferred to use ammonium polyphosphate having a weight average polymerisation degree of 20 to 2000. By applying the flame retardant of the present invention on fibers as a flame retardant resin composition containing a binder resin, environmentally soft flame retardant textile products can be stably obtained.
Claims12
A polyphosphate flame retardant comprising complex particles of a polyphosphate compound having flame retardancy and a silicone resin, in which said polyphosphate compound includes particles having an average particle size of 3 to 50 μm, and said silicone resin is expressed by a general formula (RnSiO(4−n)/2)m where R is methyl, alky, fluoroalkyl, phenyl or vinyl, n=1 to 3, and m≧2, and said silicone resin is adhered around the particles of said polyphosphate compound.
A flame retardant composition prepared by compounding a polyphosphate flame retardant comprising complex particles of a flame retardant polyphosphate compound and a silicone resin to a binder resin, in which said polyphosphate compound includes particles having an average particle size of 3 to 50 μm, and said silicone resin is expressed by a general formula (RnSiO(4−n)/2)m where R is methyl, alkyl, fluoroalkyl, phenyl or vinyl, n=1 to 3 and m≧2, and said silicone resin is fixed around the particles of the polyphosphate compound.
A flame retardant textile product prepared by a procedure in which a flame retardant resin composition prepared by compounding a polyphosphate flame retardant comprising complex particles of a flame retardant polyphosphate compound and a silicone resin in a binder resin is fixed on fibers, in which said polyphosphate compound includes particles having an average particle size of 3 to 50 μm, and said silicone resin is expressed by a general formula (RnSiO(4−n)/2)m where R is methyl, alkyl, fluoroalkyl, phenyl or vinyl, n=1 to 3 and m≧2, and said silicone resin is fixed around the particles of the polyphosphate compound.
