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
The invention relates to CABLE MATERIALS preparation method, be specifically related to a kind of production method of low smoke and zero halogen mica mineral enhancement type flame resistant cable material.
Background technology
Current China fire retardant mine cable product is fire-retardant based on Halogen, this mine cable discharges a large amount of dense smoke and corrosive halide when burning, cause casualties and corrode various equipment, on market, low smoke and zero halogen mica mineral flame resistant cable material temperature tolerance is low simultaneously, cementability is poor, easy layering.
Summary of the invention
The object of the invention is the production method of inventing a kind of low smoke and zero halogen mica mineral enhancement type flame resistant cable material, adopt production technique of the present invention can optimize the temperature tolerance of CABLE MATERIALS, the dense smoke for human body when alleviating presence of fire injures.
Comprise the following steps:
1) prepare burden: by mica mineral, silica gel, the bonding rheological agent of antioxygen, polyethylene master batch, Low Density Polyethylene, high density polyethylene(HDPE) mixing; Each weight percent of the bonding rheological agent of wherein said mica mineral, silica gel, antioxygen, polyethylene master batch, Low Density Polyethylene, high density polyethylene(HDPE) is: 10 ~ 15%, 15 ~ 18%, 5 ~ 10%, 20 ~ 30%, 15 ~ 20%, 15 ~ 25%;
2) mix: mixing of preparing burden above;
3) hot melt: hot melt of preparing burden above;
