Abstract

The invention discloses a high-elasticity, corrosion-resistant, wear-resistant and oil-resistant rubber material, and belongs to the technical field of rubber materials. The rubber material comprisesnitrile rubber, MgO, thermoplastic polyurethane, polyvinyl chloride, stearic acid, paraffin, carbon black N550, carbon black N330, paraffin oil, a promotor CZ, a promotor TRA, a promotor BZ, a promotor TMTD, an anti-aging agent 4010NA, anti-aging agent BLE, silicone master batch and sulfur. Through a modification process, the heat resistance, corrosion resistance, environment stress crack resistance and wear resistance of the rubber material are improved, and the rubber material has the advantages of superior aging resistance, particular outdoor aging resistance, ultraviolet light irradiationresistance, insusceptibility to decomposition and yellowing, and capability of keeping original luster and color. Meanwhile, the rubber material has high corrosion resistance, can resist chemical products such as acids, alkalis, salts and grease, and has excellent oil resistance, cold resistance and high temperature resistance, and the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a high-elastic, corrosion-resistant, wear-resistant and oil-resistant rubber material. Background technique [0002] Rubber materials refer to the connection sealing joints used in underground engineering pipelines, the permanent deformation joints provided in the concrete pouring of infrastructure projects, and the highly elastic sealing rubbers suitable for subways, tunnels, culverts, water conservancy and other projects. The rubber material used for the waterstop. The medium that can cause irreversible changes in the chemical structure of the rubber is called a chemically turbid medium. When rubber products are in contact with chemical media, the rubber and compounding ingredients are decomposed due to chemical action, resulting in chemical corrosion, and sometimes unbalanced swelling of rubber. The chemical substances entering the rubber break and disso...
