Problems solved by technology

Existing tires used by professional vehicles such as fire trucks and hazardous chemical vehicles use ordinary heavy duty radial tire tread rubber compositions like ordinary vehicle tires. Because they do not have the function of flame retardancy and fire prevention, there is a safety hazard of fire and combustion
Although some existing flame-retardant rubber compositions have certain fire-proof performance, the basic performance of the tire is significantly reduced, and the service life is seriously affected.

Embodiment 1

[0046] Each component is measured in parts by mass, see Table 1.

[0047] The mixing method of this rubber composition is as follows:

[0048] After masticating the raw rubber with a closed rubber mixer for 0.5-1min, add some carbon black, high-dispersion silica and all components except the vulcanization system and protection system, and mix for 2-3min at 150-160°C Internal discharge, complete the preparation of a masterbatch;

[0049] After the film is parked for 8 hours, add the primary masterbatch, remaining carbon black and components of the anti-aging system to the closed rubber mixer, and mix for 2-3 minutes at a temperature of 145-155°C to complete the secondary masterbatch. preparation;

[0050] After the film is parked for 8 hours, add the second-stage masterbatch and all the components of the vulcanization system into the closed rubber mixer, and mix for 2-3 minutes at a temperature of 95-105°C to discharge the rubber to complete the preparation of the final rubbe...

Embodiment 2

[0053] Each component is measured in parts by mass, see Table 1, and the mixing method is the same as in Example 1.

Abstract

The invention provides a rubber composition applied to a fireproof series of TBR tire treads, and belongs to the field of tires. The rubber composition has the advantages of excellent material mechanical property, good processing technology performance, especial suitability for the fireproof series of TBR tire treads and ability in obviously improving flame-retardant and fireproof safety performance of the tires. The rubber composition applied to the fireproof series of TBR tire treads, disclosed by the invention, is prepared from the following components in a weight proportion: 100 parts of matrix rubber, 5 to 8 parts of activator, 5 to 20 parts of white carbon black, 36 to 51 parts of carbon black, 0.5 to 2 parts of silane coupling agent, 1 to 4 parts of processing aid, 1 to 2.5 parts of accelerant, 4 to 10 parts of anti-aging agent, 1 to 2 parts of sulfurizing agent and 31 to 39 parts of flame retardant.

Description

technical field [0001] The invention relates to the field of tires, in particular to a rubber composition used for treads of fireproof series radial truck tires. Background technique [0002] In recent years, it is not uncommon for cars to catch fire and burn during driving, most of which are caused by tires igniting and burning. The reason is that the tires caught fire or were ignited when encountering an open flame, or the braking time was too long and too hard when going downhill, which caused tire friction to generate heat and spontaneous combustion, or the car driving at high speed on the road in the summer high temperature season produced a large amount of The heat makes the tire reach the ignition point and catch fire. Therefore, the flame retardant and fireproof performance of tires has become a basic requirement for improving the safety of automobiles, especially professional vehicles such as hazardous chemical vehicles. [0003] The fireproof series tire is a tir...
