Silane crosslinked polyethylene cable material

Abstract

The invention relates to the technical field of insulating materials, and in particular relates to a silane crosslinked polyethylene cable material. The silane crosslinked polyethylene cable material is prepared from a base material, a catalyst master batch, silane and a crosslinking agent by virtue of proportioning and crosslinking. The silane crosslinked polyethylene cable material comprises the following components in parts by weight: 2.5-5 parts of the base material, 0.2-1 part of the catalyst master batch, 0.3 part of silane and 0.1-0.3 part of the crosslinking agent, wherein silane is vinyl trimethoxy silane. According to the silane crosslinked polyethylene cable material disclosed by the invention, the gel content of the cable material is not more than 30% by virtue of control over the component proportioning and granulating process.

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a silane crosslinked polyethylene cable material. Background technique [0002] The traditional production method in the past is a two-step method, that is, separate matrix masterbatch and catalytic cross-linking masterbatch. In the cable forming process, the two masterbatches are mixed and then cabled, and then undergo post-treatment, granulation process and cable forming process. complex. Contents of the invention [0003] In order to overcome the shortcomings of the existing technology, the invention provides a silane crosslinked polyethylene cable material. [0004] The technical solution adopted by the present invention to solve the technical problem is: a silane crosslinked polyethylene cable material, which is formed by base material, catalyst masterbatch and silane crosslinking and crosslinking. The components are as follows: [0005] Base material 2.5~5 ...
