Problems solved by technology

[0002] At present, my country's flame-retardant mining cable products are mainly halogen-containing flame-retardant. This kind of mining cable releases a large amount of smoke and corrosive halides when it is burned, causing casualties and corroding various equipment. At the same time, low-smoke cables on the market Halogen-free mica mineral refractory cable material has low temperature resistance, poor adhesion, and easy delamination

Abstract

A production method for a low-smoke halogen-free mica mineral reinforced fire-resistant cable material is disclosed. The cable material is composed of mica mineral, silica gel, an antioxygen adhesion rheological agent, polyethylene master batch, low-density polyethylene and high-density polyethylene, and is prepared by performing mixing, hot melting, extrusion, wind cooling and pelletizing. The cable material is easy for production, stable in performances and reliable in quality. After being added with the cable material, a cable has strong fire resistance, high insulation grade, strong shielding property, and strong resistance to strong acids and alkalis, and also is improved in ultraviolet resistance. After being added with a little amount of the cable material, a cable has the mechanical strength improved by two times or more, and does not easily generate layering phenomenon.

Description

technical field [0001] The invention relates to a preparation method of a cable material, in particular to a production method of a low-smoke halogen-free mica mineral-enhanced fire-resistant cable material. Background technique [0002] At present, my country's flame-retardant mining cable products are mainly halogen-containing flame-retardant. This kind of mining cable releases a large amount of smoke and corrosive halides when it is burned, causing casualties and corroding various equipment. At the same time, low-smoke cables on the market Halogen-free mica mineral refractory cable material has low temperature resistance, poor adhesion and easy delamination. Contents of the invention [0003] The purpose of the present invention is to invent a production method of low-smoke halogen-free mica mineral-enhanced fire-resistant cable material. The production process of the present invention can optimize the temperature resistance of the cable material and reduce the smoke dam...
