Abstract

The invention discloses a low-noise tire and a preparation method thereof, the low-noise tire comprises diene rubber, silicon dioxide particles, polylactic acid particles, sulfur and a vulcanization accelerator, and the average particle size of the polylactic acid particles is 40-60 microns. The rubber composition adopted by the tire contains polylactic acid particles and silicon dioxide particles with specific sizes, so that the noise of the tire is remarkably reduced, and the fuel economy and the wear resistance of the tire are improved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and particularly relates to a low-noise tire and a preparation method thereof. Background technique [0002] On March 1, 2014, China piloted the "Technical Specifications for Green Tires", which put forward requirements and directions for the green application prospects of tires. At present, the recycling application of waste tires is mostly concentrated on low-grade products such as tire retreading, environmentally friendly reclaimed rubber and rubber powder production, and it is difficult to use them at a high level. [0003] With the increasing use of automobiles, people's demand for automobiles has shifted from a single functional demand to a quality demand level. For example, the requirements for the noise value heard during the driving of the car are getting lower and lower, and the noise generated by the tires is particularly critical. But at the same time, the safety of the ...
