1. A method for manufacturing a bulletproof and explosion-proof tubeless tire;
first, an innerliner (60) is attached to a carcass cord ply (40) to make a carcass innerliner, and then steel wire skeleton layers (51) and intermediate rubber layers (52) are laminated to each other to make an explosion-proof layer (50), using a first stage building machine to complete the first stage forming of the carcass innerliner, the explosion-proof layer (50) and a belt (20) to obtain a semi-finished embryo, and then using a second stage building machine, the semi-finished embryo and the tread slab base (10) are formed in the second stage to obtain an embryo, which is baked and stored for 8˜96 h and then vulcanised to obtain a bulletproof and explosion-proof tire;
the bulletproof and explosion-proof tire is sequentially provided with the innerliner (60), carcass cord ply (40), belt (20) and tread slab base (10) from the inside to the outside;
the shoulder of the bulletproof and explosion-proof tire is provided with shoulder wedges (30);
an explosion-proof layer (50) is arranged between the belt (20) and the carcass cord ply (40);
the explosion-proof layer (50) consists of a number of steel wire skeleton layers (51) and a number of intermediate rubber layers (52), both of which are interlaced with each other, and the ends of the explosion-proof layer (50) are all intermediate rubber layers (52);
the steel wire skeleton layers (51) are steel wire braided layers or steel wire winding layers;
the steel wire braided layer is braided by means of a steel wire braiding machine according to a certain braiding balance angle, the number of steel wire braiding layers is 1˜3 layers, and the braiding balance angle is 53˜56°;
the steel wire winding layer is wound by a steel wire winding machine according to a certain winding balance angle, the number of steel wire winding layers is 1˜3 layers, and the winding balance angle is 53˜56°;
each intermediate rubber layer (52) is extruded by means of an extruder with a thickness of 0.3˜0.6 mm.
