Abstract

The invention provides a drag chain cable sheathing material special for a robot. The drag chain cable sheathing material special for the robot is prepared from the following raw materials in percentage by mass: 32 to 45 percent of polyvinyl chloride resin, 4.8 to 7.2 percent of thermoplastic polyurethane elastomer rubber, 2.4 to 3.6 percent of nitrile rubber, 28 to 38 percent of a polyester plasticizer, 10 to 20 percent of a filler, 1.5 to 5 percent of a stabilizing agent, 0.1 to 0.5 percent of an antioxidant, 2 to 4.8 percent of a composite flame retardant, and 0.1 to 0.5 percent of a lubricant. The invention belongs to the technical field of cable materials; the cable sheathing material provided by the invention has excellent oil resistance, wear resistance, processability and aging resistance.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to a drag chain cable sheath material specially used for robots and a preparation method thereof. Background technique [0002] The towline cable is a highly flexible special cable that can move back and forth with the towline and is not easy to wear and tear, which can prevent the cable from being entangled, pulled off, and scattered. Drag chain cables are widely used in the fields of robots, CNC machine tools and fire protection systems. With the in-depth development of industrial automation and intelligence, higher requirements are placed on the performance of drag chain cable materials. [0003] Polyvinyl chloride resin has the advantages of low price and corrosion resistance, and has been widely used as the main raw material for cable insulation and / or sheathing. However, the existing PVC cable sheath materials have unsatisfactory heat resistance and oil re...

AI Technical Summary

Problems solved by technology

However, the existing PVC cable sheath materials have unsatisfactory heat resistance and oil resistance, low heat distortion temperature, poor impact resistance and poor processing performance, which limits their application in intelligent fields such as robots. application

[0004] Chinese patent application CN 108178889A discloses a heat-resistant and oil-resistant polyvinyl chloride cable sheath material for robots. The raw materials include: 100 parts by weight of polyvinyl chloride, 3-9 parts of thermoplastic polyurethane elastomer, 3-10 parts of nylon, 20-35 parts of nitrile rubber, 3-8 parts of chlorinated polypropylene, 1-8 parts of nano calcium carbonate, 1-5 parts of cobalt aluminate, 2-5 parts of hydrotalcite, 2-10 parts of magnesium hydroxide, red mud 2-9 parts, 5-12 parts of graphene oxide, 2-5 parts of epoxy soybean oil, 2-3.8 parts of vinyl tris (β-methoxyethoxy) silane, 0.5 parts of perfluoroalkyl ethyl acrylate -2.9 parts, 2-5 parts of stabilizer, 2-3.5 parts of stearic acid, 0.3-1.5 parts of dicumyl peroxide, 2-5 parts of zinc oxide, through polyvinyl chloride, thermoplastic polyurethane elastomer, nylon, butyl Nitrile rubber achieves synergistic promotion under the action of chlorinated polypropylene, which endows the sheath material with excellent elasticity, wear resistance, oil resistance and heat resistance, but the composition is more complex, and the amount of nitrile rubber used is larger, resulting in aging resistance The performance is not ideal, and the modification steps of graphene oxide are complicated
