Description

A kind of nanometer boron fibre strengthens fireproofing cable material without halide for building and preparation method thereof
Technical field
The present invention relates to CABLE MATERIALS field, particularly relate to a kind of nanometer boron fibre and strengthen fireproofing cable material without halide for building and preparation method thereof.
Background technology
In recent years, along with expanding economy, particularly the developing rapidly of the industry such as electric power, electronics and informationization, flame-retardant electric wire and cable consumption supporting is with it increased severely, because people are more and more higher to the environmental protection of cable, safety requirements, although traditional PVC sheath material good flame resistance, cheap, easily process, due to a large amount of hydrogen halides and dense smoke can be released when it burns, cause " the secondary harm " of fire, to HUMAN HEALTH and environmental damage very large.Current people more and more attaching importance to environmental protection, be particularly applied in the environment that subway, boats and ships, building, household electrical appliance etc. are high to environmental requirement, the electric wire of low smoke and zero halogen sheath material is widely used, and becomes worse.
The low-smoke halogen-free flame-retardant sheath material provided in the market usually adopts in ethylene vinyl acetate system and adds a large amount of inorganic hydrogen aluminum oxide, magnesium hydroxide flame retardant system, because the powder content of inorganic combustion inhibitor reaches between 50%-70% usually, this just requires that body material and powder have good pardon, ethylene vinyl acetate is a kind of ideal material, for widely using.But because the physical strength of ethylene vinyl acetate material, hardness are lower, cause the physical strength of material low, wear no resistance, cause cable cable top layer sheath in mounting and installation process damaged, especially electric cable with large cross-section situation is even more serious, once cable sheath breaks likely cause the instability of network system, cable body can be subject to various infringement, can not effective operation of available protecting cable; And existing low-smoke halogen-free flame-retardant sheath material binding is bad, affect effective use of cable.
The subject matter that current low-smoke halogen-free flame-retardant sheath material exists has easy scuffing, burn into weares and teares, fractures, extrudes processing difficulties, and easy to crack, easy thermal distortion, the problem such as aging, need improving technique and material, improve the performance of CABLE MATERIALS.
