Anti-adhesion low-smoke halogen-free and flame-retardant polyolefin cable material

Abstract

The invention discloses an anti-adhesion low-smoke halogen-free and flame-retardant polyolefin cable material. The invention belongs to the technical field of cable materials, and solves the problem of possible adhesion between cables. The cable material is prepared by adopting the following method of: by weight part, weighing 85-95 parts of an ethylene-vinyl acetate copolymer, 55-65 parts of highdensity polyethylene, 30-38 parts of magnesium hydroxide, 50-70 parts of aluminum hydroxide, 0.15-0.35 part of melamine urate, 10-22 parts of red phosphorus, 20-40 parts of a hyperdispersant, 17-23 parts of silicon dioxide, 7-13 parts of zinc hydroxystannate, 15-21 parts of nano BaSO4, 1-2 parts of polylactic acid and 0.5-1.5 parts of sodium hyaluronate evenly, conducting internal mixing for 10-15min at 130-140DEG C for 10-15min, and then performing extruding and granulating at 115-140DEG C, thereby achieving the effects of enabling the cable material to have good smoke-suppressing and flame-retardant properties and high anti-adhesive properties.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to an anti-blocking low-smoke halogen-free flame-retardant polyolefin cable material. Background technique [0002] Cable material refers to the plastic used for wire and cable insulation and sheathing. As people become more and more aware of fire prevention, people pay more and more attention to the flame retardant performance of cable materials. However, adding halogen-containing plastics to cable materials Flame retardants, when a fire occurs, will produce toxic fumes, causing greater casualties, so now low-smoke, halogen-free, flame-retardant cable materials are more and more widely used. [0003] There is still room for improvement in the smoke suppression, flame retardant and mechanical properties of the existing cable materials, and when the cables are coiled, if the anti-adhesion performance of the cable materials is poor, the cables will directly stick to each other, which wi...
