Abstract

The invention discloses a low-temperature-resistant high-density polyethylene power cable protective tube. The low-temperature-resistant high-density polyethylene power cable protective tube is composed of high-density polyethylene, flexibilizer, filler, coupling agents, plasticizer and bridging agents, the flexibilizer adopts liquid acrylate rubber, the filler adopts mica powder, the coupling gents adopt gamma-thiopropyl triethoxy silane, the plasticizer adopts dioctyl maleate, and the bridging agents adopt trimethyl hexamethylene diamine. The low-temperature-resistant high-density polyethylene power cable protective tube is composed of the high-density polyethylene, the flexibilizer, the filler, the coupling agents, the plasticizer and the bridging agents, and the low-temperature-resistant high-density polyethylene power cable protective tube has the advantages of being high in toughness, good in abrasive resistance, high in strength, stable in quality, convenient to process and produce, good in low temperature resistance and long in service life.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a low-temperature-resistant high-density polyethylene power cable protection tube. Background technique [0002] High-density polyethylene is commonly known as low-pressure polyethylene. Compared with LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, it has good electrical insulation, impact resistance and cold resistance. , mainly used in blow molding, injection molding and other fields. [0003] The cable sheath is the outermost layer of the cable, and the tube worn outside is called a protective tube. With the continuous development of productivity, the currently used polyethylene sheath can no longer meet the requirements of use, so a new type of modified polyethylene is urgently needed to fill the market demand. Contents of the invention [0004] The object of the ...
