Problems solved by technology

As we all know, in the industry, the temperature grade of 105°C and below can meet the requirements no matter whether XLPE, XLPVC or PVC is used. Above 150°C, the application of silicone rubber, fluoroplastics, polyimide and other varieties has also matured, but in the middle temperature grade (such as 125°C, 150°C) application development, there is a big gap with foreign countries

Abstract

The invention relates to the field of insulation wires and cables, in particular to a silane cross-linked polyethylene insulation silver gray electric wire and cable and a preparation method thereof. The silver gray electric wire and cable comprises an insulation material and a wire, wherein the insulation material is prepared from the following components: LLDPE-7042, LDPE, a silane coupling agent, a cross-linking agent DCP, an antioxidant 300 and a catalyst masterbatch, and the catalyst masterbatch is prepared from the following components: LLDPE-7042, LLDPE-8320, PP, an antioxidant 1010, an antioxidant DLTP, an antioxidant 1024, organic tin, a fluorine rubber masterbatch, a UV absorber and a silver gray masterbatch. The insulation material provide by the invention is mainly used for replacing the existing PVC material, and the insulation property is better than that of PVC; the PVC emits toxic and harmful gases when the electric wire is on fire due to aging and the like, while the silane insulation material is non-toxic and harmless.

Description

technical field [0001] The invention relates to the field of insulating material wires and cables, in particular to a silver-gray wire and cable made of a silane crosslinked polyethylene insulating material and a preparation method thereof. Background technique [0002] The types of polyolefins used in the cable industry mainly include PE, PP, EVA and EEA, etc. Among them, the relatively large amount and long application history are mainly PE, which include HDPE, MDPE, LDPE, LLDPE and cross-linked XLPE. Their application Needless to say. The current application and development trends of polyolefins in the industry mainly focus on the following aspects: [0003] (1) Serialization and perfection of halogen-free and low-smoke materials [0004] Halogen-free, low-smoke, flame-retardant cable materials have been developing rapidly in recent years, and thermoplastic materials that meet the requirements of the IEC92-359 standard have been more and more widely used. With the requ...
