Problems solved by technology

However, the current standards are the abrasion resistance test of cables under flat and static conditions, which cannot satisfy the problems that arise during the actual application process. Therefore, it is necessary to establish a printing abrasion resistance test method that can better simulate the actual application environment of cables to ensure that cables Scratch-resistant effect of marking on the surface of the sheath

Abstract

The invention relates to a printed wiping-resistant black thermoplastic low-smoke zero-halogen flame-retardant polyolefin cable sheathing material and belongs to the technical field of sheathing material for wire and cable. The sheathing material comprises 100 parts of matrix resin, 120 to 180 parts of flame retardant, 1.0 to 2.0 parts of polyester coupling agent, 0.03 to 0.08 parts of initiator, 1 to 3 parts of lubricant, 0.5 to 2.5 parts of antioxidant, 1.0 to 3.0 parts of surfactant, 2 to 3 parts of black masterbatch. The base resin is composed of the following raw materials in proportions, by weight: 70 to 90 parts of ethylene copolymer and 10 to 30 parts of polymer compatibilizer; the flame retardant is composed of the following raw materials in proportions, by weight: 90 to 140 parts of aluminum hydroxide and 30 to 60 parts of magnesium hydroxide. The sheathing material has the advantages that the requirements of a reliable combination of ink and sheathing surface is satisfied, an ink adhesion force is improved, a limit oxygen index of the material is enhanced, a wetting of the ink on the plastic surface is improved and a logo on the sheathing material is not easy to be wiped to remove.

Description

technical field [0001] The invention belongs to the technical field of sheath materials for electric wires and cables, and in particular relates to a black thermoplastic low-smoke halogen-free flame-retardant polyolefin cable sheath material with printing and abrasion resistance Background technique [0002] At present, there are mainly three ways to print on the surface of the cable sheath, namely printing on the printing wheel, printing on the inkjet printer and printing on the laser. The printing wheel printing needs to be frequently designed and replaced according to different products, which cannot print dynamically changing meters, and is not suitable for cable products with uneven surfaces; laser printing has high equipment costs, and once the logo is wrongly printed, it cannot be changed by solvent wiping Disadvantages: Inkjet printer printing is widely used by cable manufacturers because of its convenient operation, easy change of printing content and font size, abi...
