Technical Field

The invention belongs to the field of rubber materials, and particularly relates to a rubber material for a creeper tread of an armored vehicle and a preparation method of the rubber material.

Background

In the rubber industry, the formulation of rubber materials is an extremely important technology, because all rubber products require the rubber materials through the cooperation of main rubber, a vulcanization system, a protection system, a reinforcing filling system and a process operation system in the rubber formulation. The existing rubber has poor aging resistance and poor tear resistance at high temperature, and has the requirements on shock absorption, link torsion and the like of the creeper tread rubber, and the existing rubber material cannot meet the use requirements of the creeper tread of an armored vehicle.

Disclosure of Invention

The invention provides a rubber material for a creeper tread of an armored vehicle and a preparation method thereof, which improve the tear resistance and the aging performance of the rubber material at high temperature.

In order to solve the technical problems, the invention provides an armored vehicle track shoe rubber material which is characterized in that: the feed is prepared from the following raw materials in parts by weight: 80-90 parts of solution-polymerized styrene-butadiene rubber, 5-10 parts of pre-dispersed short fibers, 40-70 parts of carbon black, 5-10 parts of zinc oxide, 2-10 parts of a coupling agent, 6-15 parts of a plasticizer and 3-8 parts of stearic acid.

A preparation method of the rubber material for the track shoe of the armored vehicle comprises the following steps: firstly, adding solution polymerized styrene-butadiene rubber and pre-dispersed short fibers into an internal mixing device for mixing for 2-3 min; secondly, adding various raw materials except carbon black and continuously mixing for 4-5 min; finally, mixing the carbon black for multiple times, and discharging the glue after uniform tamping.

Has the advantages that: the invention adopts universal raw materials in the rubber industry, and is convenient to purchase. The application of the pre-dispersed short fiber improves the tear resistance of the rubber material, and simultaneously, the short fiber is matched with other raw materials to improve the aging resistance at high temperature. Due to the use of special components and a mixing process, the rubber material not only can meet the special requirements of the use environment, but also has strong manufacturability. The service life is prolonged. The aging coefficient at high temperature reaches more than 0.6, and the tearing strength can reach 25 KN/m. Thereby meeting the requirements of the rubber bearing load and the torsional stress of the creeper tread in the motion process of the medium and heavy tank.
