Description
Technical field
The present invention relates to a kind of cable material, especially a kind of MVQ silicone rubber insulation material belongs to field of cable technology.
Background technique
Insulating cement is the multicomponent compound adhesive with good electrical insulation capability.It is with pitch, natural resin or synthetic resin
Material of main part, has very high viscosity under room temperature, and when use heats to improve mobility, makes it easier to perfusion, dipping, coating.
It can solidify after cooling, can not also solidify.Its main feature is that being free of volatile solvent, it can be used as collector surface protection.Insulation rubber
Glue is in electric utility using very extensive.
With wire and cable industrial expansion, people propose higher tightened up performance requirement to cable products.Cable
Sheath is the indispensable intermediate structure part of electric wire, plays a part of protection power source line, guarantees the energization safety of power supply line, allows
The isolation of the media such as copper wire and water, air, avoids the occurrence of leaky.However existing power supply line sheath is for a long time in strong day illumination
It penetrates down, it may occur that embrittlement phenomena, or even rupture, to influence the service performance of power supply line.
Material such as coating, building plastic, rubber product etc., the test applied to outdoor through climate, such as illumination, cold
Comprehensive caused by heat, wind and rain, bacterium etc. to destroy, tolerance is weatherability.The drastic change of temperature is the baptism to material,
At a high temperature of certain, such or such variation can occur for the service performance of cable material, some can even lose using valence
Value, so, using rubber as insulation or the material of sheath, if not having certain heat resistance, even if other performance is good again,
It is not available.
Summary of the invention
The purpose of the present invention is in view of the above shortcomings of the prior art, provide a kind of MVQ silicone rubber insulation material, the material
With heat-resisting, oil resistant, resistance to chemical corrosion, the service life of cable can be extended, it is a large amount of to save conductor material and insulating materials,
Make the light softness of cable.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of MVQ silicone rubber insulation material, characterized in that
Each component including following parts by weight is prepared: 50-70 parts of MVQ silicon rubber, 30-40 parts of ethylene propylene diene rubber, aluminium hydroxide
3-6 parts, 10-16 parts of high wear-resistant carbon black, 2-6 parts of dodecyldimethylammonium hydroxide inner salt, 15-25 parts of modified additive, plasticizer 5-12
Part, 12-18 parts of vulcanizing agent, 2-8 parts of paraffin hydrocarbon ils, 5-10 parts of auxiliary curing agent, 12-25 parts of acrylic rubber powder, deionized water
15-25 parts, 5-8 parts of colorant, 2-8 parts of chlorinated paraffin, 2-5 parts of magnesia, 1-6 parts of lead monoxide.
The modified additive is made of the component of following weight parts: 40-50 parts of haloflex, 4-5 parts of turpentine oil, poly- third
1-3 parts of olefin(e) acid sodium crosses tantalum boride 2-3 parts, aluminium nitride 3-5.
The plasticizer is selected from paraffin, dioctyl phthalate, chlorinated paraffin, epoxidized soybean oil and dioctyl sebacate
One of or it is a variety of.
The vulcanizing agent cumyl peroxide.
The auxiliary curing agent iso-cyanuric acid triallyl ester.
The partial size of the acrylic rubber powder is 45-60nm.
Silicon rubber refers to that main chain is alternately made of silicon and oxygen atom, and the rubber there are two organic group is usually connected on silicon atom
Glue.Common silicon rubber is mainly made of the silicon oxygen chain link containing methyl and a small amount of vinyl.Silicon rubber can be improved in the introducing of phenyl
High- and low-temperature resistance performance, the heatproof and oil resistance of silicon rubber then can be improved in the introducing of trifluoro propyl and cyano.Silicon rubber is resistance to low
Temperature is functional, generally remains to work at -55 DEG C.After introducing phenyl, reachable -73 DEG C.The heat resistance of silicon rubber is also very prominent
Out, at 180 DEG C can long-term work, a little higher than 200 DEG C can also bear several weeks or longer time it is still flexible, be instantaneously resistant to 300
DEG C or more high temperature.The good permeability of silicon rubber, OTR oxygen transmission rate are highest in synthetic polymer.In addition, silicon rubber is also
It with physiological inertia, not will lead to the prominent characteristic of blood coagulation, therefore be widely used in medical field.[1]
Silicon rubber divides thermal vulcanization (high temperature vulcanized silica gel HTV), room temperature vulcanized (RTV), and wherein room temperature vulcanized divides polycondensation again
Response type and addition reaction-type.High temperature silicone rubber is mainly for the manufacture of various silastic products, and room temperature silicon rubber is then mainly
It is used as bonding agent, Embedding Material or mold.Thermal vulcanization dosage is maximum, and thermal vulcanization divides methyl silicone rubber (MQ), first again
Base vinylsiloxane rubber (VMQ, dosage and product grade are most), methyl vinyl phenyl silicon rubber PVMQ(be low temperature resistant, resistance to spoke
Penetrate), there is also eyeball silicon rubber, fluorine silicone rubber etc..
Ethylene propylene diene rubber is the copolymer of ethylene, propylene and a small amount of non-conjugated diene hydrocarbon, is one kind of EP rubbers,
With EPDM(Ethylene Propylene Diene Monomer) it indicates, because its main chain is by chemically stable saturated hydrocarbons group
At only containing unsaturated double-bond in the side chain, therefore the ageing-resistant performances such as its resistance to ozone, heat-resisting, weather-proof are excellent, can be widely used for vapour
The fields such as vehicle component, building water-proof material, electric wire and cable jacket, heat-resistant rubber hose, adhesive tape, automotive sealant.
Acrylic rubber (hereinafter referred to as ACM) is elastomer obtained by being copolymerized using acrylate as main monomer, master
Chain is saturated carbon chains, and side group is polar ester groups.Since special construction assigns its many excellent feature, such as: heat-resisting, ageing-resistant,
Oil resistant, resistance to ozone, uvioresistant etc., mechanical property and processing performance be better than fluorubber and silicon rubber, heat-resisting, resistance to ag(e)ing and
Oil resistivity is better than nitrile rubber.ACM is widely used in various high temperature, in resistance to oil environment, becomes auto industry in recent years and focuses on
A kind of sealing material promoted is developed, high temperature resistant oil sealing, crankshaft, valve rod, cylinder liner, the hydraulic oil pipeline of automobile are especially used for
Deng the import of domestic demand almost all dependence at present.
Material resistance to ultraviolet radiation of the present invention can be excellent, and flexibility is good, and has excellent physical mechanical property and resistance
Performance is fired, it is durable, raw material basis is established for the exploitation of Ultraviolet radiation resistant power cord sheath, and meet UL and European Union ROHS
It is required that environmental protection is completely, solves ultraviolet light resistant performance, physical mechanical property, environmental-protecting performance etc. and be difficult to reach requirement comprehensively
Technical problem has huge Social benefit and economic benefit.
