Description
Technical field
The present invention relates to a kind of fire-retardant TPE cable material with heat conductivility and preparation method thereof.
Background technology
Along with the progressively exhaustion of the energy and going from bad to worse of environment, greatly developing new forms of energy has become the important of world community
Strategic objective.In recent years, new-energy automobile technology has become as the pollution of automobile industry response environment and Jiao of alleviating energy crisis
Point property technology, every country and whole world Ge great automobile vendor put into huge fund the most one after another and carry out the development of new-energy automobile.
Comparing orthodox car, new-energy automobile possesses low energy consumption, low noise, zero-emission and the advantage such as pollution-free, it has also become the Chinese government
The industry paid high attention to and support energetically.Under intensive support on policy, new-energy automobile has sailed the track of fast development into.With
This simultaneously, the supporting basic electrically-charging equipment construction of new-energy automobile also becomes development priority.In the recent period, National Development and Reform Committee issues
" new-energy automobile charging infrastructure development guide (2015-2020) ", clearly proposes to the year two thousand twenty, and the whole nation is by newly-increased concentration
1.2 ten thousand, formula charging and conversion electric station, distributing charging pile 4,800,000, with satisfied national 5,000,000 new-energy automobile charge requirement.Cut
To the end of the year 2014,780, charging and conversion electric station is built together in the whole nation, and alternating current-direct current charging pile 3.1 ten thousand, for more than 120,000 new-energy automobiles
Offer charging and conversion electric services.New-energy automobile is vehicle-mounted or charging pile charging cable forms as the basic of new-energy automobile electrically-charging equipment
Part, its performance has important impact to whole charging process.But, new-energy automobile charging cable is as New-style electrical wire
Cable, it uses and requires to be different from traditional electric wire.It not only needs to possess not because of long-term various severe natural environment
Impact and reduce reliability and the safety of charging cable, but also need to possess will not be because the most artificially bending, distort, pulling
Even automobile rolls and acid-base solution, detergent, gasoline, the phenomenon such as immersion of machine oil, causes charging cable mechanically and electrically
Gas damages thus affects the performance of cable material, also will not, use frequency height, load current longer because of the charge and discharge process time
Value is relatively big (maximum can arrive 400A), and the heat collection party that conductor produces in a large number causes electric cable heating, resistance to increase, thus forms temperature
Spending more high resistance the biggest, the biggest heating of resistance is the biggest, and the biggest temperature of generating heat is the highest, the phenomenon that the highest cable life of temperature is the shortest,
And reduce its thermostability, resistance to ag(e)ing and flame-retarding characteristic.Therefore, harsh service condition is required to meet new-energy automobile charging wire
Material must have a characteristic of excellence, particularly high-temperature resistant grade, high heat dispersion (high thermal conductivity coefficient), electrical insulating property, resistance to
Ozone aging, heat oxygen aging resistance, oil resistivity, anti-flammability etc..It addition, have halogen, low halogen cable material when breaking out of fire, release has
Poison, harmful gas and smog, harm human health and Environmental security, therefore meeting European Union's RoSH standard and REACH regulation etc. has
The halogen-free flameproof of the environmental regulations closed has become as the standard-required of new-energy automobile charging wire.
Thermoplastic elastomer (TPE), i.e. TPE, both had the processing characteristics of thermoplastic, had again the physical property of vulcanite
Can, safety non-toxic, quality softness, comfortable feel, resilience are good, anti-wet and slippery, also have the feature of environmental protection.In addition based on SEBS
TPE also has the highest electrical insulating property, resistance to low temperature.Thermoplastic elastomer (TPE) is the most progressively applied to originally be pertaining only to vulcanite
Application.In the recent decade, the fast development of electronic apparatus, communication and automobile industry brings the height of thermoplastic elastomer (TPE)
Speed development, particularly some high-grade consumer electronics fields, such as earphone cord, electric wire, power line etc..But existing thermoplasticity
Elastomer the combining including performance such as including tear-resistant performance, ageing-resistant performance, heat resistance, oil resistance, thermostability, resistance to water
Closing poor-performing, its application at present is confined to field less demanding to above-mentioned combination property, and for filling as new-energy automobile
Electric wires etc. are to tear-resistant performance, heat resistance, heat dispersion (heat conductivity is the biggest, and heat dispersion is the best) and oil resistance etc.
For the application that performance requirement is higher, by the deficiency of the performance of existing thermoplastic elastomer (TPE) own, limit it in this field
Development.
CN105837911A discloses a kind of insulating heat-conductive CABLE MATERIALS, including the raw material of following parts by weight: high density is gathered
Ethylene 60 70 parts, modified polypropene 20 30 parts, heat filling 15 25 parts, polyolefin elastomer 6 10 parts, glass fibre 58

Feel is poor, is not suitable for new-energy automobile charge cable material.
From relevant modified TPE patent and document, it has been found that improve New-energy electric vehicle high-voltage charging cable and lead
Hot patent almost without.And, from the point of view of the patent of the new-energy automobile high-voltage charging cable of report, only generally exist simultaneously
New-energy automobile charge cable can be met and use the partial properties index required, and reach comprehensively to meet performance indications, i.e. simultaneously
There is high-tensile, high-tear strength, 125 DEG C of grades of heatproof, high thermal conductivity coefficient, ageing-resistant performance gasoline good, resistance to, machine oil
Good, material reaches halogen-free flameproof V0 grade, cable reaches VW-1 grade, then almost without, thus constrain it at new forms of energy
