Embodiment 1

[0029] A kind of rubber material of novel run-flat tire, it is made up of the raw material of following percentage by weight:

[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.

Abstract

The invention relates to the field of rubber materials, in particular to a novel rubber material of a run-flat tire. The novel rubber material is prepared from the following raw materials by weight percent: 25 to 40 percent of SEBS, 40 to 48 percent of white mineral oil, 7.5 to 10 percent of POE elastomer, 15 to 28 percent of copolymer PP, and 0.1 to 2 percent of antioxidant. The invention provides the novel rubber material of the run-flat tire which is resistant to high temperature and aging.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a rubber material for a novel run-flat tire. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume ...
