Embodiment Construction

[0033] The present invention is implemented like this:

[0034] Take 100 parts of polyvinyl chloride resin as the base material, add 16 parts of graphite powder, 0.5 part of oleic acid amide, 40 parts of trioctyl trimellitate, 2 parts of tribasic lead sulfate, 1 part of dibasic lead phosphite, hard 0.7 parts of lead fatty acid, 10 parts of tricumyl phosphate, 12 parts of chlorinated paraffin, 20 parts of calcium carbonate, 3 parts of zinc stannate, 2 parts of water and zinc borate, 0.2 part of tris(nonylphenyl phosphite), 1 part stearic acid. Mix the components, add the materials into the high-temperature mixer, heat and stir at about 100°C, and use the spiral feeding method to enter the twin-screw mixer for mixing, and control the temperature at 120-135°C. Then add a single-screw extruder to extrude and granulate. Put the materials into the screening machine for screening, dry them with a spin dryer, then enter the dryer for drying, and finally measure and pack to obtain th...

Abstract

The invention relates to a heat-resistant flame-retardant polyvinyl chloride cable material and a manufacturing method thereof. According to a formula, the material comprises the following components: polyvinyl chloride resin, a flame-retardant filler, a dispersing agent, a plasticizer, lead sulfate tribasic, dibasic lead phosphate, lead stearate, isopropyl triphenyl phosphate, chlorinated paraffin, calcium carbonate, zinc stannate, water and zinc borate, an antioxidant and stearic acid. The material has the advantages that: a large amount of graphite serving as a flame-retardant and high-temperature-resistant filler is added; and the graphite and a proper amount of chlorinated paraffin and zinc stannate together assist in enhancing the flame retardant property of a cable. The filler has high compatibility with other materials and high dispersion and is matched with other stabilizers; and the product has high heat-resistant stability and flame retardant property. Meanwhile, the lubricating performance of the product is improved to a great extent; the PVC mixed material has high uniform plasticity and high-speed melt fluidity; and the product has a smooth surface, soft handfeel and superior performance.

Description

technical field [0001] The invention relates to a heat-resistant and flame-retardant cable material, in particular to a heat-resistant and flame-retardant polyvinyl chloride cable material and a manufacturing method thereof. Background technique [0002] In fire accidents, fires caused by wires and cables cannot be ignored. When the cable burns, it will also produce toxic and harmful gases and smoke. The smoke has light reduction properties. Generally, the visibility can be reduced to zero after 20s. In addition, there are thermal damage, poisoning, suffocation and other harmful effects, which cause casualties. Equipment damaged. Especially in power plants, substations, communication rooms and program-controlled exchange rooms where there are a large number of electrical equipment and a large number of cables are densely laid, once a fire will spread rapidly, how to prevent the burning of wires and cables is a major issue in the wire and cable manufacturing industry.
