Abstract

The invention discloses a shock-reducing rubber material with high mechanical property and a manufacturing method of the shock-reducing rubber material. The shock-reducing rubber material is characterized by comprising the components in percentage by mass: 30-55 percent of natural rubbers, 10-20 percent of ethylene-propylene-diene monomer rubbers, 10-20 percent of brominated butyl rubbers, 3-5 percent of short fibers, 10-15 percent of nano-carbon black, 10-15 percent of white carbon black (SiO2), 1-2 percent of stearic acid (SA), 3-5 percent of zinc oxide (ZnO), 3-4 percent of magnesium oxide (MgO), 1-2 percent of nano calcium carbonate, 2-4 percent of accelerants, 1-1.5 percent of paraffin, 2-3 percent of Vaseline, 0.5-1 percent of an anti-aging agent, 0.5-1 percent of a coupling agent, 1-3 percent of bis-silane tetrasulfide (Si-69) and 2-5 percent of sulphur (S). According to the shock-reducing rubber material, the mechanical strength, the anti-aging resistance and the oil-resistance performance of the rubber material can be improved, the corrosion to the material by mycete is postponed, the flexibility and relatively-high tension strength and elasticity of the material can be kept, so that the service life of the material can be greatly prolonged. The obtained product has the advantages that the loss factor index can reach 0.52-0.55, DIN abrasion performance index can reach 100-120 mm<3>, and the rubber material is high-elastic in shock-reducing property and has wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of composite material manufacturing, and in particular relates to a high-mechanical-performance shock-absorbing rubber material and a manufacturing method thereof. Background technique [0002] In recent years, short fiber rubber composite material has been deeply researched and widely used as a new type of polymer material. It combines the rigidity of short fiber and the high elasticity of rubber, which can endow rubber products with high elasticity and wear resistance. Excellent overall performance. If the short fibers are properly oriented in the rubber matrix, the above-mentioned properties of rubber products can be further improved. Therefore, this provides a technical idea for the development of high-elastic shock-absorbing sole materials. [0003] When preparing rubber products, the dosage of various compounding agents including accelerators, vulcanizers, antioxidants, etc. exceeds the solubility of...
