Abstract

The invention discloses a cable scarfskin which comprises the following materials in parts by weigh: ethylene-vinyl-acetate copolymer, magnesium hydroxide, aluminum hydroxide, maleic anhydride grafted ethylene- vinyl-acetate copolymer, maleic anhydride grafted polyethylene, silicone, silane, fillers, antioxygen 1010, zinc oxide, ferric oxide, epoxidized soybean oil, toner and polyethylene. The cable scarfskin has the characteristics of good flexibility, high impact resistance, high environmental stress resistance, and the like, by compounding EVA and PE. A flaw which can cause crack can not appear. Meanwhile, in order to overcome the defects of flammability, a plurality of auxiliaries, such as aluminum hydroxide and magnesium hydroxide, are added, thereby improving the fire resistance of the cable scarfskin. Materials comprising halide are not added, which makes the cable scarfskin have no halogen. The fillers are added to make the heat stability of the cable scarfskin good. The cable scarfskin can be used at 105 DEG C.

Description

technical field [0001] The invention belongs to the technical field of cable production, in particular to a cable sheath and a preparation method thereof. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. [0003] Due to the long-term use, the temperature of the working environment will be very high, so the outer sheath of the cable is required to have the property of high temperature resistance. [0004] At the same time, most of the existing cable sheaths contain halides. In a fire, the halogen-containing cables will consume a lot of oxygen and release a lot of smoke, such as carbon monoxide and carbon dioxide, as well as acidic and toxic gases, which will damage the noses, Mouth and throat, smoke also makes victims easily lo...
