Abstract:
A dedicated material for manufacturing a special safety tyre rubber for wheeled combat vehicles and aircrafts in the army, with the following components of the following weight proportion: 28-40 parts of polyisoprene, 19-30 parts of silicone rubber, 15-25 parts of thermoplastic elastomer, 10-18 parts of magnetic powder, 10-15 parts of paraffin oil, 0.8-2 parts of flexibilizer, 5-10 parts of silicone oil, and 0.5-2 parts of antioxidant. The material of the present invention may be used as a carcass material of a special safety tire marching in unfavorable environments such as rough terrain, a lot of sharp foreign matters, and high temperature and open fire. The dedicated material has properties of ordinary tire rubber at a normal temperature, and it also has characteristics such as resistant against high temperature, against burning, against flame and against aging in an extremely hot environment. Furthermore, the material has properties such as resistance against bullets, against prick and against explosion. The material can withstand attack of shells of light-weighted explosives. The dedicated material can be manufactured by a simple fabrication process, and it is recyclable and pollution-free.
