Tire tread rubber material modified with borane coupling agent material and preparation method thereof

Abstract

The invention provides a tire tread rubber material modified with a borane coupling agent material and a preparation method thereof. The tire tread rubber material comprises the following components in parts by weight: 80-100 parts of rubber, 40-50.0 parts of medium and super wear-resistant carbon black, 1.0-3.0 parts of the borane coupling agent and 10.0-20.0 parts of a rubber additive. Accordingto the preparation method of the tire tread rubber material modified with the borane coupling agent material, a low-temperature one-step rubber mixing system is used, and the preparation method comprises the following steps: mixing in two stages, wherein in a first stage, rubber, medium-super wear-resistant carbon black, silicon dioxide, the borane coupling agent, zinc oxide, stearic acid and ananti-aging agent are subjected to discharging rubber, tabletting and cooling, and in a second stage, a rubber master batch, sulfur, an accelerant and an anti-scorching agent are subjected to tabletting and cooling.

Description

technical field [0001] The invention relates to a rubber composition for tire production, in particular to a tire tread rubber material modified by a borane coupling agent material and a preparation method thereof, belonging to the technical field of rubber. Background technique [0002] Due to the actual national conditions of our country, the road conditions are not very good in many areas, especially in areas where economic construction and mineral mining are important. Many short-distance transport vehicles mainly rely on overloading to transport sand, stone, iron ore powder, and coal. The roads in these mining areas are not paved. , the road surface is basically sharp stones, gravel, slag, etc., and the quality of the road conditions is quite poor. For example, some dump trucks transporting ore climb uphill with heavy loads. For more than 10 kilometers, the empty car quickly went downhill and returned, frequent braking and turning, driving on the simple road in the mini...

[0002] Due to the actual national conditions of our country, the road conditions are not very good in many areas, especially in areas where economic construction and mineral mining are important. Many short-distance transport vehicles mainly rely on overloading to transport sand, stone, iron ore powder, and coal. The roads in these mining areas are not paved. , the road surface is basically sharp stones, gravel, slag, etc., and the quality of the road conditions is quite poor. For example, some dump trucks transporting ore climb uphill with heavy loads. For more than 10 kilometers, the empty car quickly went downhill and returned, frequent braking and turning, driving on the simple road in the mining area day and night, the requirements for the tire tread rubber used are very strict, and require anti-puncture, anti-collapsing and chipping, The wear resistance and driving performance are very high, especially for vehicles operating in open-pit iron mines. The tires used are easily punctured by the sharp ore scattered on the simple paved road, and the tires are seriously damaged, leading to early tire damage. , which brings great losses to users and enterprises in the mining area, and also causes a waste of resources
