[0030]
Embodiment 2
[0032] A kind of rubber material of novel run-flat tire, it is made up of the raw material of following percentage by weight:
[0033]
Embodiment 3
[0035] A kind of rubber material of novel run-flat tire, it is made up of the raw material of following percentage by weight:
[0036]
[0037] In the above examples, SEBS is Kraton G7000, POE elastomer is LG Chemical LC170, copolymerized PP is ethylene copolymerized polypropylene, and antioxidant is 2,2,4-trimethyl-1,2-dihydroquinoline polymer.
[0038] The preparation method of a kind of rubber material of novel explosion-proof tire is, embodiment and comparative example are weighed according to formula, and above-mentioned material is weighed by certain ratio, and SEBS, POE elastomer, copolymerized PP, white mineral oil and antioxidant are weighed. Put them together in a high-speed mixer and mix them. The compounded materials are non-bonding and uniformly dispersed, then put them into a low-speed mixer to cool, and finally mold and cool to make high-temperature-resistant automobile tires.
