Abstract
The composition of the present invention is a kind of crosslinked, flame-retardant resin composition, which comprises a base polymer of EVA-VC, chlorinated polyethylene, thermal stabilizers, antioxidants, flame-retardant fillers, lubricants and monomers with multifunctional group. The composition essentially comprises 100 weight parts of EVA-VC, 10 to 70 weight parts of chlorinated polyethylene, 40 to 120 weight parts of flame-retardant fillers, and 5 to 20 weight parts of monomer with multifunctional group. In addition, the composition is crosslinked by electron beam to be used as the material for sheath layer of electric wire or cable durable to high voltages.
Claims16
A crosslinked, flame-retardant resin composition which essentially comprises 100 weight parts of EVA-VC having 25 to 75% by weight of vinyl chloride, 10 to 70 weight parts of chlorinated polyethylene having 25 to 45% by weight of chlorine content, 40 to 120 weight parts of inorganic flame-retardant fillers, and 5 to 20 weight parts of monomer with multifunctional group.
A crosslinked, insulated electric wire having a property of flame-retardancy, which is structured to have a crosslinked protecting sheath layer that encapsulates a wire coated with an insulting layer, the sheath layer essentially comprising 100 weight parts of EVA-VC having 25 to 75% by weight of vinyl chloride, 10 to 70 weight parts of chlorinated polyethelene having 25 to 45% by weight of chlorine content, 40 to 120 weight parts of inorganic flame-retardant fillers, and 5 to 20 weight parts of mononer with multifunctional group.
A crosslinked, flame-retardant resin composition comprising EVA-VC, chlorinated polyethylene, at least one flame-retardant filler selected from the group consisting of antimony trioxide, metal hydroxide, zinc borate, clay, asbestos, mica, calcium carbonate and barium sulfate and a monomer with a bifunctional or trifunctional group capable of crosslinking to contribute to a three-dimensional structure.
