Problems solved by technology

There are many colors of low-smoke halogen-free cables, and different cable colors have different absorption wavelengths of ultraviolet light. In actual production, adding more color masterbatches may even lead to non-crosslinking of materials
The UV-crosslinked low-smoke and halogen-free materials on the market are used to produce light-colored cables, which have insufficient crosslinking stability.

Abstract

The invention discloses an ultraviolet cross-linked low-smoke halogen-free flame-retardant polyolefin cable material and a preparation method thereof; the cable material is composed of a silane grafted polyethylene material A and an ultraviolet cross-linked low-smoke halogen-free flame-retardant polyolefin flame-retardant master batch B in a weight ratio of 10-15:90-85 (A:B). After being extruded, the cable material prepared by the invention is subjected to the online crosslinking through UVLED irradiation equipment. Herein the two crosslinking modes of ultraviolet crosslinking and silane crosslinking are combined, so that the crosslinking efficiency and stability are remarkably improved, and the method can be suitable for production of thick-wall and colored crosslinking low-smoke halogen-free cables.

Description

technical field [0001] The invention relates to an ultraviolet light cross-linked low-smoke halogen-free flame-retardant polyolefin cable material and a preparation method thereof. Background technique [0002] Polyolefin materials are flammable materials. When there are external fire sources or internal faults in the operation of wires and cables, wires and cables are easy to burn. In order to reduce fire losses, it is necessary to add flame retardants to the materials to achieve flame retardancy of wires and cables. . Low-smoke, halogen-free, flame-retardant polyolefin cable materials have been widely used because of their environmental protection, low-smoke, and non-toxic characteristics. [0003] Wire and cable materials can improve high temperature resistance, crack resistance, mechanical properties and flame retardancy after cross-linking. The cross-linking methods of cross-linked low-smoke halogen-free flame-retardant cable materials mainly include electron accelera...
