Abstract
The invention discloses a method for manufacturing a bulletproof and explosion-proof tubeless tire, first, the innerliner is attached to the carcass cord ply to make the carcass innerliner, and then the steel wire braided layers and the intermediate rubber layers are laminated to each other to make an explosion-proof layer, using a first stage building machine to complete the first stage forming of the carcass innerliner, explosion-proof layer and belt to obtain a semi-finished embryo, and then using a second stage building machine, the semi-finished embryo and the tread slab base are formed in the second stage to obtain the embryo, which is baked and stored for 8˜96 h and then vulcanised to obtain a bulletproof and explosion-proof tire; through the second stage forming process, the invention solves the problem that the explosion-proof layer is difficult to form due to the excessively hard metal material when making the embryo.
