Method for manufacturing a bulletproof and explosionproof tubeless tire
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.
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.
2. The method for manufacturing a bulletproof and explosion-proof tubeless tire of claim 1 , the braiding balance angle refers to the complementary angle of the angle between the braided steel wire and the tire crown line.
3. The method for manufacturing a bulletproof and explosion-proof tubeless tire of claim 1 , the winding balance angle refers to the complementary angle between the winding steel wire and the tire crown line.
4. The method for manufacturing a bulletproof and explosion-proof tubeless tire of claim 1 , the tread slab base ( 10 ) is provided with a tire pattern with a thickness of 10-20 mm.
5. The method for manufacturing a bulletproof and explosion-proof tubeless tire of claim 1 , the thickness of tread slab base ( 10 ) is 20˜45% of the thickness of tire tread pattern.
6. The method for manufacturing a bulletproof and explosion-proof tubeless tire of claim 1 , the belt ( 20 ) is 2-4 layers, and its cord angle is designed to be 65˜80°.
7. The method for manufacturing a bulletproof and explosion-proof tubeless tire of claim 1 , the thickness of the innerliner ( 60 ) is 2˜5 mm.
