[0038] The first step, the preparation of the outer layer 1;
[0039] Fully mix polyolefin resin and polyolefin flame retardant at a weight ratio of 100:5-30 to obtain a mixed raw material; then extrude the mixed raw material through a film blowing machine or a casting machine, and the extrusion temperature is 160-220°C. The extrusion speed is 5-30m / min to obtain the outer layer 1;
[0040] The polyolefin flame retardant is decabromodiphenyl ether, ammonium polyphosphate or phosphoric acid ester;
[0041] The second step, the preparation of the middle layer 2;
[0042] (1) Preparation of flame-retardant fabric-21: using at least one of flame-retardant polyester fiber, flame-retardant acrylic fiber, flame-retardant vinylon or flame-retardant nylon to obtain flame-retardant fabric-21 through a weaving process;
[0043] (2) Preparation of flame-retardant fabric 222: using at least one of flame-retardant viscose fiber, para-aramid fiber, meta-aramid fiber, polyarylene oxadiazole...
