Description
Technical field
The present invention relates to a kind of cable sheath material, particularly a kind of sheath material of solar photovoltaic cable; The invention still further relates to the cable that above-mentioned materials is made.
Background technology
Photovoltaic cable is to comply with the market development demand, the development of active response country photovoltaic industry, and great majority all design and adopt common PVC sheath material.And common PVC material contains the toxic substances such as halogen, lead, easy contaminate environment, and temperature resistant grade is low, and easily aging, short-time overload capacity is poor, not anti-ozone and water vapour, the shortcomings such as life-span weak point.And photovoltaic cable embrittlement easy to crack under long-term mal-condition, leakage fire occurs, and the hydrogen chloride gas under the Fire Conditions also can be affected to the life-span of photovoltaic cable and Controlling System easily to the corrosion of photovoltaic apparatus.
This just requires photovoltaic cable to have the severe environment performance requriementss such as good high-low temperature resistant, anti-ozone.The sheath of existing photovoltaic cable is mainly used PVC sheath material, low smoke and zero halogen material etc., be that on 03 04th, 2009 publication number is CN201204086 such as the applying date, patent name is the patent of Weatherproof solar cable, the applying date is that the publication number on October 29th, 2008 is CN101295562 for another example, and patent name is the patent of production method of power cable for solar photovoltaic power generation assembly.Although adopt the photovoltaic cable of this jacket structure can bear the temperature variation of certain limit, cost is too high, cable itself is short work-ing life, and environment for use is limited, uses such as the environment that is unfavorable for severe cold.
Summary of the invention
The invention provides a kind of have fabulous high-low temperature resistant, oil resistant, UV resistant, anti-ozone and weathering resistance effect, be adapted to the sheath material of solar photovoltaic cable that the environment of severe cold lay to use and the cable that utilizes above-mentioned materials to make, this cable cost and cable sheath proportion are all relatively low.
In order to reach above-mentioned technique effect, technical scheme of the present invention is: a kind of sheath material of solar photovoltaic cable is characterized in that described sheath material comprises the following weight parts component:
Described thermoplastic elastomer TPO is take PP as hard segment and EPDM is the blend of soft chain segment, described compatilizer POE is the POE of maleic anhydride graft, described silane is the ultra-high molecular weight polysiloxane, described 1010 oxidation inhibitor are pentaerythritol tetrathioglycollate, and it is anti copper agent that described cupric ion is snapped away from agent.
The multiple mixing of nanometric magnesium hydroxide, zinc borate and organosilicon modifier forms fire retardant.
A kind of solar photovoltaic cable comprises sheath, it is characterized in that sheath comprises the following weight parts component:
Described thermoplastic elastomer TPO is take PP as hard segment and EPDM is the blend of soft chain segment, described compatilizer POE is the POE of maleic anhydride graft, described silane is the ultra-high molecular weight polysiloxane, described 1010 oxidation inhibitor are pentaerythritol tetrathioglycollate, and it is anti copper agent that described cupric ion is snapped away from agent.
Photovoltaic cable sheath material of the present invention has not only strengthened the stability of restrictive coating as main adding silicone master batch and phosphorus flame retardant take amorphous polyolefin, make cable have high-low temperature resistant and good flame retardant properties, and the cable that makes that such material adopts advanced cross-linking radiation technique to make has stronger cold-resistant property, strengthen the sheath use range, long service life and meet environmental protection standard.The polyolefin jacket material have fabulous high-low temperature resistant, oil resistant, UV resistant, anti-ozone and its temperature resistant range of weathering resistance can reach+150 ℃--60 ℃.
