Abstract

The invention relates to a rubber nanocomposite material for highly wear-resistant heavy-duty tire treads and a preparation method thereof, which belong to the technical field of high-performance tires. The invention prepares the NR / NBR (Natural Rubber / Nitrile Butadiene Rubber) rubber nanocomposite material with good wear resistance. By means of the combination of epoxidized natural rubber-compatiblizing modification and nano-filler and in-situ dispersing modification by a silane coupling agent, the problem of high heat buildup caused by the combination of NBR is solved, and the wear resistance of the nanocomposite material is further enhanced. The obtained NR / NBR / ENR material has excellent wear resistance, wet-skid resistance and physical and mechanical properties, meeting the performance requirement of high-performance tire materials. In addition, the invention also has the following advantages: the processing technology is easy to operate, and is matched with actual processing equipment of factories, the rubber nanocomposite material can be directly produced and the like.

Description

Technical field [0001] The invention belongs to the field of truck tires, and specifically relates to a rubber nano composite material for the tread of a high wear-resistant truck tire and a preparation method thereof. Background technique [0002] Due to its high load-bearing capacity and complex road conditions, all-steel radial truck tires have higher requirements on the wear resistance of the tread. Existing all-steel tires generally have problems such as poor wear resistance, low tread life, and environmental pollution caused by wear and fall. It is of great significance to the tire industry to seek to improve the wear resistance of the tire under the premise of ensuring the good overall performance of the tire tread and to make the tread meet the environmental protection requirements. [0003] The wet skid resistance is an important indicator to measure the safety of tires, especially in rainy weather. When a car is driving on a wet road in a rainy day, the wet grip of the ...
