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 black wire and cable of insulating material, in particular to a black wire and cable of silane crosslinked polyethylene insulating material and a preparation method thereof. The black wire and cable includes insulating material and wires, and the insulating material is prepared from the following components: LLDPE-7042, LDPE, silane coupling agent, crosslinking agent DCP, antioxidant 300 and catalyst masterbatch; the catalyst The masterbatch is composed of the following components: LLDPE‑7042, LLDPE‑8320, PP, antioxidant 1010, antioxidant DLTP, antioxidant 1024, organotin, fluororubber masterbatch and black masterbatch. The insulation material of the invention mainly replaces the current PVC material, and its insulation performance is better than that of PVC, while PVC will emit poisonous and harmful gas when the wires are aging and catch fire, while the silane insulation material is non-toxic and harmless.

Description

technical field [0001] The invention relates to the field of black wire and cable of insulating material, in particular to a black wire and cable of 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 requiremen...
