Problems solved by technology

And due to the particularity of the use environment, the road surface is complex, such as uneven potholes, there are many sharp foreign objects such as ore and gravel, and the tires are impacted by uneven force and cut by different degrees of sharp foreign objects during driving, causing the tires to be damaged during use. The rubber material is cut during the process, and the tire rubber is used to collapse and fall off, and the service life of the tire is low

Abstract

The invention discloses a method for preparing cutting-resistant mine tire tread rubber, and is characterized in that the tread rubber comprises the raw material components by mass: 10-20 parts of natural rubber, 50-60 parts of styrene butadiene rubber, 20-40 parts of oil-extended styrene-butadiene rubber, 1-6 parts of a tearing resistant agent, 5-15 parts of white carbon black, 3-5 parts of a protection system, 5-10 parts of an active agent, 50-65 parts of a reinforcing agent, 5-15 parts of a plasticizer, 1.5-2.5 parts of a vulcanizing agent and 0.5-1.5 parts of a promoter; the raw materialsof the tread rubber are mixed with an internal mixer to prepare the product. The rubber material prepared by the method has the characteristics of resistance to cutting and good containment to a roadsurface, and can avoid the problem that chunking and block falling of rubber after cutting in the use process of a tire.

Description

technical field [0001] The invention relates to a compound formula for a mine tire, in particular to a method for preparing a cut-resistant mine tire tread compound. Background technique [0002] The tires of mine trucks are large, and the tires are under a large load. And due to the particularity of the use environment, the road surface is complex, such as uneven potholes, there are many sharp foreign objects such as ore and gravel, and the tires are impacted by uneven force and cut by different degrees of sharp foreign objects during driving, causing the tires to be damaged during use. During the process, the rubber material is cut, and the tire rubber is used to collapse and fall off, resulting in a low service life of the tire. The rubber compound with excellent cutting resistance can make the tire tolerant to uneven road surfaces. The rubber compound has good toughness and is not easy to be cut and damaged to form blocks. [0003] Styrene-butadiene rubber is a polysty...
