The invention discloses a compound material manufacture technology that uses modified nanometer kaolin to take place of nanometer montorillonite clay as antiflaming synergic action bulking agent. It contains matrix resin, fire retardant, antiflaming synergic action bulking agent, lubricant, and antioxidant; the matrix resin is the mixture of ethylene vinyl acetate copolymer, thermoplastic elastomer and grafting compound. The fire retardant contains three type fire retardants; and the antiflaming synergic action bulking agent is kaolin. The weight portions of the constituents are: 100 portions matrix resin, 100-140 portions fire retardant, 10-30 portions, 1-5 portions lubricant, 1-3 portions antioxidant. The invention has the advantages of low cost, easy technology, and excellent flame retardant property.
