Abstract

The invention provides a low-heat-generation distortion-resistant and compression-resistant rubber recipe, which comprises natural rubber, butadiene rubber, zinc oxide, stearic acid, anti-aging agents RD, anti-aging agents 4010 NA, super tackifying resin, coumarone, carbon black N990, carbon black N234, white black carbon 1165, silane coupling agents SI-69, insoluble sulfur, accelerants CZ, antiscorching agents CTP, accelerators DTDM and paraffin. A preparation method of the rubber comprises the steps of natural rubber plastication, filler and crude rubber blending and vulcanization system addition. The matching proportion of all ingredients in the formula of the rubber material provided by the invention is reasonably regulated, so that the obtained rubber has the advantages of low heat generation, good flexing resistant performance and high intensity. The consumption of the rubber material in the mechanical movement process is obviously reduced; the use time is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to a rubber formula with low heat generation, anti-distortion and anti-compression and a preparation method thereof. Background technique [0002] The application of metal tracks in production is increasing day by day, and the scope of application is also wider and wider. It can be applied not only to vehicles, construction machinery, weapons, but also to agricultural machinery. Tracks are usually used in combination. The shape of each part of the track is relatively simple, the production efficiency is high, and it is easy to cooperate with other structures or components. Metal track is simple in structure, small in mass and low in cost. It is the most common track application, and it is usually applied after connecting multiple metal tracks. [0003] In the connecting structure of the metal track, there is a connecting part that requires a non-metallic materia...
