Abstract

The invention discloses a preparation method of a highway shock mount mixed compound. The preparation method comprises the following steps: heating and raising the temperature of a mixing roll to 90-120 DEG C, proportionally adding a nitrile rubber, a hydrobisphenol A epoxy resin and a glycidyl ester epoxy resin into the mixing roll to mix evenly; then adding various additives to mix to obtain a finished product of a mixed rubber; and the various materials comprise 85-100 parts of the nitrile rubber, 15-30 parts of the hydrobisphenol A epoxy resin, 10-20 parts of the glycidyl ester epoxy resin, 10-20 parts of montmorillonoid, 15-35 parts of lignin, 5-15 parts of castor oil, 3-10 parts of zinc oxide, 5-12 parts of N-phenyl-N'-cyclohexyl p-phenylenediamine, and 10-18 parts of DCP vulcanization accelerator by ratio. By optimizing the ratio of the material composition and controlling the preparation parameter, the obtained butyronitrile rubber achieves excellent low temperature resistanceand oil resistance at the same time, and is suitable for the low-temperature severe climatic environment, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a method for preparing a mixed rubber for road shock-absorbing bearings. Background technique [0002] The so-called rubber compound refers to the uncrosslinked and fluid rubber material in which the compounding ingredients are mixed in block, granular and powder raw rubber. Raw rubber or plasticized rubber is called mixed rubber after mixing the rubber with the compounding agent according to the formula. The rubber compound is the raw material for the manufacture of rubber products, that is, the semi-finished product, so the colloidal dispersion quality of the rubber compound is directly related to the quality of the finished product. At the same time, the viscoelasticity and rheology of the rubber compound directly affect the processing performance of the rubber material and post-production Advanced molding, extrusion, calendering, extrusion and other processing technology. ...
