Abstract

The invention discloses a modified natural rubber composite material for tire treads, relating to the technical field of natural rubber processing. The modified natural rubber composite material is prepared from the following raw materials in parts by quality: 80-100 parts of natural rubber, 10-15 parts of carbon nanotube, 5-10 parts of magnesium carbonate, 3-8 parts of calcium silicate, 2-6 parts of diphenyl silanediol, 3-8 parts of coumarone indene resin, 1-5 parts of rosin, 2-5 parts of trioctyl metabenzenetricarboxylate, 2-3.5 parts of kaolin, 0.5-3 parts of zinc dialkyl dithiophosphate, 1-2 parts of titanium white, 3-8 parts of benzoperoxide, 2-6 parts of superfine magnesium hydroxide and 1-5 parts of zinc borate. By using the carbon nanotube to modify the natural rubber, the prepared rubber composite material has the advantages of high temperature resistance, wear resistance, slip resistance, aging resistance and favorable mechanical properties.

Description

Technical field: [0001] The invention relates to the technical field of natural rubber processing, in particular to a modified natural rubber composite material for tire treads. Background technique: [0002] Natural rubber is a renewable polymer material with superior comprehensive properties, featuring high elasticity, high strength and wear resistance. It is widely used in aerospace, national defense and military industry, tires, and medical elastomers, and occupies a very large role in the national economy. Important position. In addition, with the continuous advancement of engineering vehicle technology, the load and work intensity of the vehicle continue to increase. Whether it is an engineering tire with a diagonal line structure or a radial steel wire structure, the tire tread rubber wear performance and tire rolling resistance performance are not very rational, and The service life is short, which has a certain impact on the safety of the tire. How to make use of ...
