Restoration: The present invention introduces active carboxyl groups into the main chain of polymer molecules through copolymerization, and greatly improves the interfacial bonding force between materials and rubber products through the effects of intermolecular hydrogen bonds and van der Waals forces, thereby overcoming traditional rubber-plastic composite materials. The problem of poor interface bonding force and shear resistance.

Low-smoke zero-halogen cable material for high power and preparation method thereof

The invention discloses a low-smoke zero-halogen cable material for high power. The low-smoke zero-halogen cable material comprises, by weight, 2-4 parts of chlorcosane, 6-8 parts of calcium carbonate, 3-4 parts of linear low-density polyethylene, 2-4 parts of melamine cyanurate, 2-3 parts of sulphur, 1-2 parts of accelerant, 3-5 parts of dioctadecyl 3,3'-thiodipropionate, 2-3 parts of boric acid, 2-4 parts of diisooctyl sebacate, 1-3 parts of dimethyltin bis(isooctylmercaptoacetate), 2-4 parts of triallyl isocyanurate, 4-5 parts of low-molecular PE wax, 40-60 parts of ethylene propylene diene monomer, 2-5 parts of trimellitate and 8-12 parts of filling agent. The low-smoke zero-halogen cable material has the excellent mechanical performance, heat resistance and weather resistance, the added triallyl isocyanurate can remarkably shorten the vulcanizing time, and production cost is reduced.
