Flame-retardant high-temperature-resistant polyvinyl chloride and preparation method thereof

PendingCN121851565AImprove flame retardant performanceHigh flame retardant efficiencyPlastic/resin/waxes insulatorsInsulated cablesEpoxyPolymer science
The invention relates to flame-retardant and high-temperature-resistant polyvinyl chloride and a preparation method thereof, and belongs to the technical field of polyvinyl chloride. The polyvinyl chloride comprises the following components in parts by weight: 100 parts of polyvinyl chloride resin, 12-25 parts of organic silicon-zinc hybrid flame retardant, 2-8 parts of reactive compatibilizer and 5-15 parts of core-shell functional filler. According to the organic silicon-zinc hybrid flame retardant, acrylic acid and aminopropyltrimethoxysilane are subjected to condensation to generate acrylamide silane, then the acrylamide silane is coordinated with zinc acetate to form a crystal structure, and silicon and zinc synergistic flame retardance is achieved; the core-shell functional filler takes zinc hydroxystannate as a core and zinc borate as a shell, and has smoke suppression and catalytic char formation functions; and the reactive compatibilizer is a copolymer containing an epoxy group, so that the interfacial compatibility of the flame retardant and the filler with PVC is improved, the safety performance of the material is improved, and the material is suitable for manufacturing cable sheaths.
