Abstract

The invention discloses an outer rubber material for a steel wire-woven hydraulic rubber pipe and a preparation method of the outer rubber material, relating to the field of rubber materials. The outer rubber material is prepared from the following raw materials in parts by weight: 100 parts of rubber, 9 parts of an activating agent, 3 parts of an anti-aging agent, 20-25 parts of a plasticizer, 77 parts of a reinforcing filler, 5 parts of an adhesive and 3.3-3.75 parts of a vulcanizing agent. The outer rubber material has the beneficial effects that by utilizing the outer rubber material, the elongation of the rubber pipe is more than or equal to 600%, the rubber pipe cracks only after 72 hours when the ozone concentration reaches 50mg / L or the temperature reaches 120 DEG C, and the ozone aging resistance, the thermo-oxidative aging resistance, the wear resistance and the plasticity of the rubber pipe are improved, furthermore, the breaking strength of the rubber pipe is more than or equal to 12MPa, the hardness of the rubber pipe is more than or equal to 73 DEG C, the service life of the rubber pipe is prolonged, and the production cost of a user is lowered.
