TLDR
In this article, a heat-resistant flame-retardant polyvinyl chloride cable material and a manufacturing method for its manufacturing was described. And 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 retardent property of a cable.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 andsuperior performance.read more
