Heavy-load static conductive solid tire tread rubber material and preparation method thereof

Abstract

The invention discloses a heavy-load static conductive solid tire tread rubber material and a preparation method thereof. The heavy-load static conductive solid tire tread rubber material comprises the following components in parts by mass: 80-100 parts of natural rubber, 80-100 parts of polybutadiene rubber, 10-15 parts of graphene, 60-80 parts of carbon black, 5-10 parts of paraffin, 2-4 parts of a vulcanizing agent, 2-4 parts of a vulcanization accelerator and 1-2 parts of an anti-aging agent. The invention has the following beneficial effects: quantitative natural rubber and polybutadiene rubber are mixed with quantitative carbon black, paraffin, vulcanizing agent, vulcanization accelerator and anti-aging agent for mixing preparation, durability is increased, no crack or peeling phenomenon is generated on the tread, use durability is improved, quantitative graphene is added in the production process, the production cost is reduced, and the production efficiency is improved. The static conductive capability of the tire is greatly improved, the static electricity of a vehicle body can be timely guided out, damage and even fire breakout of parts in the vehicle caused by static electricity accumulation are avoided, and the use safety and stability are improved.

Description

technical field [0001] The invention relates to a fabric, in particular to a heavy-duty static conductive solid tire tread compound and a preparation method thereof, belonging to the technical field of tire production. Background technique [0002] Tires are circular elastic rubber products that roll on the ground and roll on various vehicles or machinery. They are usually installed on metal rims to support the body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Used under complex and harsh conditions, it is subjected to various deformations, loads, forces and high and low temperature effects during driving, so it must have high bearing performance, traction performance, cushioning performance, and at the same time, it is also required to have high wear resistance The solid tire is a kind of tire corresponding to the pneumatic tire. Innerliner, the earliest tires are solid tires. Solid tires are currently o...

Problems solved by technology

[0003] However, after the existing heavy-duty solid tire tread is used for too long, it is prone to cracking, peeling and serious wear, resulting in poor durability of the heavy-duty solid tire tread, which needs to be replaced regularly. At the same time, for some heavy-duty vehicles, Long-term use will generate static electricity. Ordinary tires have poor static conductivity, so the accumulation of static electricity on the car body will easily cause damage to the internal parts of the vehicle or even catch fire, which will bring great safety hazards to the vehicle and personal safety.
