Problems solved by technology

[0002] The cable storage basket of the port mechanical spreader is close to the sea, and it is operated outdoors. The wind is strong, the environment is harsh, and the wind direction is changeable. The cable will shake a lot in this environment. The cable is distorted and deformed, and the cable is easy to fall off from the cable storage basket when it is retracted; in order to reduce the shaking, the weight of the cable itself is often increased, so the cable sheath rubber is required to have superior mechanical properties, corrosion resistance, and aging resistance. The cable sheath rubber is difficult to meet this requirement, and the service life is often very short

Abstract

The invention discloses a port machine cable storage basket sling cable sheath rubber and a preparation method thereof, belonging to the field of cables. The sheath rubber comprises the following components: 26.5 parts of chlorinated polyethylene 352, 2.5-3 parts of magnesium oxide, 0.3-0.5 part of antioxidant RD, 0.25-0.5 part of paraffin wax, 3.5-4.0 parts of DOS (Dioctyl Sebacate), 2.0-2.5 parts of TOTM (Trioctyl Trimellitate), 1.5-2.0 parts of white carbon black, 1.2-1.5 parts of diantimony trioxide, 1.2-1.5 parts of chlorinated paraffin 70, 0.3-0.5 part of lead stearate, 0.2-0.4 part of three salts, 6-8 parts of calcined clay, 0.2-0.3 part of A-172, 3-4 parts of high-abrasion carbon black, 3-4 parts of semi-reinforcing carbon black, 0.85-1 part of DCP (Dibasic Calcium Phosphate) and 1-1.5 parts of triallyl cyanurate (TAC). The preparation method of the port machine cable storage basket sling cable sheath rubber comprises the following steps of: firstly, blending the chlorinated polyethylene 352, adding the magnesium oxide and the like, blending and stirring uniformly; pouring filtered rubber into an internal mixer, adding the DCP and the TAC, blending uniformly, and blanking; and making the mixture into five triangular packages in an open mill, rolling for five times and delivering out sheets. The sheath rubber has excellent mechanical properties and good corrosion resistance and aging resistance.

Description

technical field [0001] The invention relates to a cable, in particular to a cable sheath rubber for a cable storage basket spreader of a port machine. The invention also relates to a method for manufacturing cable sheath rubber of a cable storage basket spreader of a port machine. Background technique [0002] The cable storage basket of the port machinery spreader is close to the sea, and it is operated outdoors. The wind is strong, the environment is harsh, and the wind direction is changeable. The cable will shake a lot in this environment, and the cable core and its outer sheath must constantly withstand a certain range The cable is distorted and deformed, and the cable is easy to fall off from the cable storage basket when it is retracted; in order to reduce the shaking, the weight of the cable itself is often increased, so the cable sheath rubber is required to have superior mechanical properties, corrosion resistance, and aging resistance. High-quality cable sheath r...
