Description

Electric vehicle car high-voltage line crosslinked insulating material
Technical field
The present invention relates to a kind of cable material, specifically a kind of 150 DEG C of grades electric vehicle car high-voltage line is exhausted with crosslinking Edge material and preparation method thereof.
Background technology
It is domestic at present solves the problems, such as electric wire it is fire-retardant on mostly using flame-proof polyvinyl chloride（PVC）Modified materials conduct Serving, this is because PVC is not only cheap, processing is simple, and since halogen-containing reason causes it just to have originally Certain flame retardant property.However halogen system fire proofing can generate a large amount of cigarette and toxic and with corrosive gas in burning Body can cause caused to the corrosion of metal objects and cannot to damage to human respiratory tract and other organs by fire merely Critical defect.Once some researches show that, in the cause of death of fire incident, more than 85% with material generate dense smoke and have poison gas Body is related.
Under the overall situation for pursuing environmental protection, safety flame retardant, inorganic anti-flaming material as a kind of Halogen series flame retardant material, because It effectively overcomes the shortcomings that halogen system fire proofing and causes the common concern of people.The great advantage of inorganic anti-flaming material It is low toxicity, low cigarette, low corrosion and cheap.In recent years, domestic and international electric wire coated material is proposed successively in the market Novel inorganic fire-retarded polymer material kind, makes inorganic fire-retarded CABLE MATERIALS be more widely applied.However, as magnalium The inorganic combustion inhibitors flame retarding efficiency such as base is low, need to add more than 60% and can be only achieved desired flame retardant effect.In this way to point of fire retardant Scattered, material machine-shaping and main mechanical performance etc. bring a series of problem, it is difficult to meet some high-end electric appliances assemblings Cable, communication cable etc. are to the index request of material.The particularly cross linked insulation material of the dedicated interior high-voltage line of electric vehicle Material, it is desirable that more stringent.
Invention content
The purpose of the present invention is exactly in order to solve the problems in the existing technology, to provide a kind of 150 DEG C of electronic vapour of grade Vehicle car high-voltage line crosslinked insulating material and preparation method thereof.
The purpose of the present invention is achieved through the following technical solutions：
Electric vehicle car high-voltage line crosslinked insulating material, it is characterised in that each component and mass percent are：Elastomer tree Fat：40%~50%, expansion type flame retardant：35%~45%, fire retarding synergist：2.0%~3.0%, compatilizer：5.0%~8.0%, table Face modifying agent：0.4%~0.6%, crosslinking agent：1.2%~1.5%, antioxidant：1.0%~1.5%, lubricant：1.0%~1.5%, it helps Agent：2.0%~3.0%.The elastomer resin is polyolefin thermoplastic elastomer (TPO), ethene-vinyl acetate polymer （EVA, VA content 30%）, one kind in ethylene propylene diene rubber (EPDM) or arbitrary combination.The expansion type flame retardant is modified poly- Ammonium phosphate is with a kind of triazine system macromolecule into charcoal foaming agent with 3：1~4：1（Mass ratio）It compounds.The fire retarding synergist is One or more combinations in 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, nano silicon dioxide, nano imvite.It is described compatible Agent is ethylene-acrylate-copolymer-maleic anhydride, maleic anhydride stem grafting polyolefin thermoplastic elastomer (TPE), ethylene-acrylic acid One or more combinations in ester-methyl propenoic acid glycidyl fat.The crosslinking agent is iso-cyanuric acid triallyl ester （TAIC）And trimethylol-propane trimethacrylate（TMPTMA）One or two combination.The surface modifier is ethylene Base trimethoxy Ethoxysilane.
The present invention also provides a kind of production technologies of electric vehicle car high-voltage line crosslinked insulating material, it is characterised in that Elastomer resin, expansion type flame retardant, fire retarding synergist, compatilizer, surface modifier, crosslinking are sequentially added in batch mixer Agent is stirring evenly and then adding into antioxidant, lubricant, auxiliary agent, is again stirring for uniformly stabilizing to 130 to 135 degrees Celsius to temperature, so The material in batch mixer is packed into extruding machine afterwards, temperature control is at 150-170 degrees Celsius, extruding pelletization.
Compared with prior art, the present invention has following advantage：The a variety of fire retarding synergists and expansion type flame retardant used It is used in compounding, further improves the flame retarding efficiency of flame-retardant system, while but also the smoke amount of material combustion drops significantly It is low.Elastomer resin can reach good compatibility each other after repeatedly optimizing simultaneously, at the same can also meet it is soft, The requirement of resisting environmental stress and cracking and heat resistance.And by a variety of lubricants with the use of the processing point that can solve material It dissipates, while production efficiency can also be improved and promote the surface smoothness of cable, and pass through and suitable antioxidant is selected to reach Material has the purpose of good resistance to daylight aging and ultraviolet aging resistance, can meet the requirement that electric wire open air uses in this way.
Specific embodiment
The present invention is further elaborated below for specific embodiment.
Elastomer resin：40%~50%, expansion type flame retardant：35%~45%, fire retarding synergist：2.0%~3.0%, it is compatible Agent：5.0%~8.0%, surface modifier：0.4%~0.6%, crosslinking agent：1.2%~1.5%, antioxidant：1.0%~1.5%, it lubricates Agent：1.0%~1.5%, auxiliary agent：2.0%~3.0%
