Cable polymer material with good flame retardation performance, and preparation method thereof

Abstract

The invention discloses a cable polymer material with a good flame retardation performance, and a preparation method thereof. The polymer material comprises, by weight, 19-28 parts of light calcium carbonate, 6-12 parts of a coupling agent, 115-148 parts of linear low density polyethylene, 0.8-1.7 parts of calcium stearate, 66-84 parts of methyl vinyl phenyl silicone rubber, 38-46 parts of epoxy resin, 12-19 parts of vegetable starch, 10-16 parts of a styrene-acrylic emulsion, 4-6 parts of glass fibers and 5-8 parts of phillygenin. Above raw materials have wide sources, different raw materialsare processed by different preparation processes, and obtained different products are synergistically reacted, so the prepared finished product has the good flame retardation performance, also has good tensile strength, good elongation at break, and good volume resistivity at 20 DEG C, and can meet the use demands of cable protection.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polymer material with good flame retardancy for cables. Background technique [0002] Electricity is the main source of energy in people's production, life and study. Electricity is transmitted from power stations to various places by cables. Cables are usually made of several wires or groups of wires and an outer insulation layer to transfer electricity or information from A wire that is transmitted from one place to another. The cable is mainly used for the transmission of strong electric energy in the transmission, distribution, transmission, transformation, and power supply lines. 500kV and above).

Problems solved by technology

[0003] At present, polyvinyl chloride resin is widely used as the sheath material for wires and cables. This material contains halogens, which will release toxic and harmful gases and generate a lot of black smoke during combustion, which not only pollutes the environment, but also easily causes suffocation in the event of a fire. Death; halogen-free low-smoke flame-retardant materials have great advantages in this regard, but they are also prone to cause degradation of the mechanical and physical properties of the base material during use, which will sacrifice part of the flame-retardant properties, which limits its application
