Environment-friendly filled cable material

Abstract

The invention provides an environment-friendly filled cable material which is prepared from the following raw materials in parts by weight: 80-90 parts of polyvinyl chloride resin, 5-8 parts of environment-friendly stabilizer, 1-2 parts of modifier CPE, 1-2 parts of barium stearate, 40-50 parts of light calcium carbonate, 10-15 parts of hollow glass microsphere, 5-8 parts of talcum powder, 4-5 parts of molybdenum oxide, 3-4 parts of copper oxide, 50-60 parts of tributyl citrate, 0.1-1 part of calcium stearate, 5-6 parts of nano bowlder powder, 15-25 parts of sodium tripolyphosphate, 0.5-1.0 part of PE (polyethylene) wax, 1-2 parts of urotropine and 12-15 parts of modifying filler. The environment-friendly filler has the advantages of environment friendliness, favorable flame retardancy, high temperature resistance, low smoke, easy stripping, favorable compatibility and favorable molding property. The preparation method is simple and easy to implement and convenient for industrial production; and the produced environment-friendly filled cable material has the characteristics of stable quality and low cost.

Description

Technical field [0001] The invention relates to the field of cable materials, in particular to an environmentally friendly filling cable material and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and the enhancement of human environmental protection awareness, various fields have higher and higher requirements for the quality and performance of wires and cables. There are more and more fires caused by the aging of wires and cables. How to reduce fires The incidence rate and mortality in the event of a fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to the poly...

AI Technical Summary

Problems solved by technology

Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to polyolefin substrates to achieve flame retardancy. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing performance of the cable material. Its softness, poor weather resistance, oil resistance, and low temperature resistance at room temperature are not very good.
