Problems solved by technology

[0002] Tire noise refers to the friction between the tire and the road when the vehicle is running at high speed. It is mainly related to the following aspects: 1. The road conditions. When driving on the road, it is easy to have a large tire noise; 2. The shape of the carcass itself and the shape of the pattern belong to the characteristics of the carcass itself. The way of flow plays a decisive role; 3. The material of the carcass itself, when the material of the tire is too hard, the air flow can basically only pass through a relatively fixed path, and sometimes due to the narrow path, etc., it will cause a sudden increase , but if the tire is soft, even if other unfavorable factors are not considered, due to problems such as air sealing caused by extrusion during operation, relatively large tire noise will be caused

Embodiment Construction

[0018] In order to clearly illustrate the technical features of the present solution, the present application will be described in detail below through specific implementation modes.

[0019] Synthesize the tread as follows:

[0020] S1. Raw material preparation:

[0021] Tire pyrolysis oil: put the tire in a pyrolysis furnace, the pyrolysis temperature is 420-500°C, the absolute pressure of operation is 0.07-0.09MPa, the obtained gas is condensed to obtain tire pyrolysis oil, which is obtained after condensation The preliminary oil is distilled, and the fraction obtained at 300-400°C is tire pyrolysis oil;

[0022] Modified carbon black: Use toluene as a solvent to repeatedly wash the lignite to obtain a solution containing the extract. The mass ratio of the mass of toluene to the dried lignite is 1:1. After the extract is colorless and transparent, add carbon black. Carry out micro negative pressure constant pressure drying after fully stirring, obtain the carbon black tha...

Abstract

A low tire noise tread and a preparation method thereof, the low tire noise tread comprises the following raw materials in parts by mass: rubber: 80-120 parts; carbon black: 4-8 parts; montan wax: 0.5-1.2 parts; Sulfur: 0.3-0.6 parts; Silane coupling agent: 0.8-1.3 parts; Stearic acid: 1-4 parts; Paraffin wax: 1-2 parts; Phenolic resin: 2-5 parts; Tire pyrolysis oil: 1.5-4 parts . This application uses the modified carbon black as an additive in tires, supplemented with phenolic resin and tire pyrolysis oil, so that the overall hardness of the tire is reduced, but it can still maintain a stable state of existence It has a certain degree of flexibility, so that the airflow can flow relatively smoothly in the tire tread during the running of the tire.
