Abstract
The invention discloses a low-smoke halogen-free flame-retardant polyethylene cable material which is characterized by comprising the following components in parts by weight: 80-85 parts of polyethylene, 5-10 parts of ethylene-vinyl acetate (EVA) copolymer, 5-15 parts of flame retardant and 0.5-1.5 parts of coupling agent. The flame retardant is a mixture of red phosphorus/montmorillonite intercalation compound, hydroxide, sodium bicarbonate and tetraisopropyl titanate. The low-smoke halogen-free flame-retardant polyethylene cable material is prepared by the following steps: weighting the flame retardant, putting the flame retardant into a high-speed mixer, spreading the coupling agent, and stirring at 1500-2000 r/min for 5-10 minutes; adding the polyethylene, EVA and antioxidant, stirring at 300-500 r/min for 3 minutes, stirring at 1500-2000 r/min for 5-10 minutes, stirring at 300-500 r/min for 2 minutes, taking out, and granulating by extruding with a double screw extruder to obtain the finished product. The tensile strength is not less than 12 MPa; the elongation at break is not less than 200%, and the flame-retardant grade is V2-V0.
Description
Technical field
The present invention relates to a kind of low-smoke non-halogen flame-retardant poly-ethylene cable material, belong to technical field of polymer materials.
Background technology
Cable is the indispensable integral part of modern people life each side, because the material of cable insulation generally is a macromolecular material, has combustibility, in order to prevent that cable catches fire, must improve CABLE MATERIALS flame retardant properties, reduce its incendivity, slowing down combustionvelocity, generally is to add certain fire retardant in macromolecular material.
The fire retardant great majority that are used for polyolefins at present are the halogen flame system, good flame retardation effect, cost performance height but big to environmental hazard, its fire retardant mechanism has determined can be fuming in fire-retardant process, produce corrosive gases, environment and human body are caused serious injury, be easy to the danger that causes the generation people to suffocate in the fire process.If the prior art halogen-free flame retardants adopts inorganic system, phosphorus system, flame-retardant systems such as phosphorus nitrogen compound system, but its flame retarding efficiency is all not high.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, develop and a kind ofly have higher flame retarding efficiency, and low cigarette, the flame retardant type poly-ethylene cable material of Halogen.
A kind of low-smoke non-halogen flame-retardant poly-ethylene cable material is characterized in that comprising following component by weight:
Polyethylene 80～85 weight parts
Ethylene-vinyl acetate copolymer 5～10 weight parts
Fire retardant 5～15 weight parts
Coupling agent 0.5～1.5 weight part
Described fire retardant is the red phosphorus/titanic acid ester that the mixes/inorganic composite flame retardants of red phosphorus/montmorillonite intercalation mixture, oxyhydroxide, sodium bicarbonate, titanium isopropylate;
Described titanate coupling agent is a titanate coupling agent.
Aforementioned low-smoke non-halogen flame-retardant poly-ethylene cable material is characterized in that described oxyhydroxide is any or boths' of magnesium hydroxide, aluminium hydroxide mixture.
Aforementioned low-smoke non-halogen flame-retardant poly-ethylene cable material is characterized in that the mass ratio of red phosphorus and polynite is 4:10 in described red phosphorus/montmorillonite intercalation mixture, and the particle diameter of polynite is 100--200nm.
Aforementioned low-smoke non-halogen flame-retardant poly-ethylene cable material is characterized in that described coupling agent is TMC-38S.
This product adopts red phosphorus/titanic acid ester/inorganic composite flame retardants, and (wherein "/" represents the meaning of and, promptly this composite flame-retardant agent is to be mixed by red phosphorus, titanic acid ester and inorganics), red phosphorus intercalation concrete intercalation process in nano imvite is seen Zhang Yanwu etc. the preparation of light hydrotalcite/red phosphorus composite fire retardant and performance [J]. thermosetting resin, 2007,22(3): 21-23.Improve effective dispersion area of red phosphorus on the one hand, improved the decomposes temperature on the one hand, improved the service efficiency of red phosphorus greatly.This system is utilized red phosphorus to be heated to contact with oxygen and is generated poly-metaphosphoric acid, makes that by the rapid carbonization of combustion thing generate carbon and water, water heat absorption back generates water vapour, but except that reducing by the oxygen in the diluent air also the combustion thing temperature, slows down combustionvelocity.In addition, poly-metaphosphoric acid can also with the charcoal effect, formed glass coke layer by combustion thing surface, isolated oxygen and heat stop combustiblematerials further to burn.Titanium isopropylate forms hard and bright and clean titanium deoxid film layer and covers on the macromolecular material at 300-650 ℃ of pyrolytic decomposition, and oxygen barrier and heat insulation can be worked in coordination with the raising flame retardant effect.This fire retardant pyrolytic decomposition is a water in addition, can take away a part of heat, and the sodium bicarbonate pyrolytic decomposition is that water and carbonic acid gas not only can be lowered the temperature and also had certain foaminess, has improved the flame retarding efficiency of thermofin.This system good flame retardation effect, the processing by coupling agent has improved the consistency with matrix greatly, has kept the required mechanical property of material itself, can be applied to the manufacturing of CABLE MATERIALS fully.
Gained finished product of the present invention has following characteristic: tensile strength is not less than 12MPa; Elongation at break is not less than 200%; Fire-retardant rank V2～V0.
