Abstract

The invention relates to a novel conductive and flame retardant mining tread mix formula of a solid tyre and a production process. 5-8% of 60-150-mesh swarf is doped into the tread mix, so that the conductive performance and the wear resistance of the tyre are improved. A certain proportion of an environmental flame retardant is added into the tread mix formula, and chloroprene rubber which is excellent in flame retardance and natural rubber which is excellent in comprehensive performance are simultaneously used, so that the problem that the existing mining solid tyre is inflammable and poor in conductivity is solved. The tyre can be widely applied to occasions related to high-temperature combustible environments in mining industry, coal mining industry, metal smelting industry and the like.

Description

technical field [0001] The invention relates to a mine solid tire, in particular to a new conductive and flame-resistant mine solid tire tread compound formula and production process. Background technique [0002] Since the reform and opening up, the national economy has grown rapidly, "scientific and technological innovation, independent innovation" has become the mainstream of domestic industrial development, and my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. With the development of industrial vehicles and other special-purpose vehicles, the requirements for tire performance are getting higher and higher. Solid tires are widely used in low-speed vehicles such as engineering vehicles because of their high load capacity, stable driving, puncture resistance, and no need for frequent repairs. It is favored by the majority of consumers and brings unlimited business opportunities to the solid tire m...
