Abstract

The invention discloses tread rubber for a carbon nano tube composite high-performance tire. The tread rubber is prepared from, by weight, 100 parts of environment-friendly regeneration rubber, 50-60 parts of carbon nano tube rubber master batch, 40-60 parts of pyrolysis carbon black, 80-100 parts of natural rubber, 15-25 parts of zinc oxide, 8-12 parts of dibutyltin dichloride, 5-9 parts of coupling agent and 8-12 parts of a vulcanizing agent. The invention further discloses application thereof for a high-performance tire tread. The excellent nano tube excellent performance advantage is brought into play, the production cost of the tire is effectively lowered, the tread rubber has the advantages of being high in abrasion resistance and heat conductivity coefficient, low in rolling resistance and endurance thermogenesis, and low in production cost. The tread rubber for the carbon nano tube composite high-performance tire is free from extraneous odor, does no harm to the human body, remarkably improves the various performances, can be used for producing the high-performance rubber, is safe and environmentally friendly, and has the wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and in particular relates to a carbon nanotube composite tread rubber for high-performance tires and an application thereof. Background technique [0002] my country's annual tire output ranks first in the world, but it is not yet a tire powerhouse. Foreign tire companies have implemented technical and trade barriers in the manufacture of high-performance tires, resulting in domestic tires that can only reach the low-end quality, and corporate profits are meager. At the same time, a large number of waste rubber products are treated as waste products and garbage in our country every year, which not only causes a lot of waste of resources, but also causes "black pollution" which has become an increasingly serious environmental problem. At present, the recycling and application of waste tires are mostly concentrated on low-grade products such as tire retreading, environmentally friendly r...
