Abstract
The invention discloses a kind of 90 ° of PVC flame-retardant sheath materials and preparation method thereof.90 ° of PVC flame-retardant sheath materials of one of which, raw material are formed by following parts by weight：40~70 parts of polyvinyl chloride resin, 3~8 parts of aluminium hydroxide, 3~5 parts of magnesium hydroxide, to 6~8 parts of benzene, 12~14 parts of adjacent benzene, 40~50 parts of plasticizer, 8~15 parts of coarse whiting, 0.2~0.4 part of lubricant, 3~8 parts of stabilizer, 4~10 parts of halogen-free flame retardants, 1~3 part of processing aid.The smog that protective cover material produced by the invention discharges in burning is few, and resistivity, oxygen index (OI) greatly promote, and have effectively reached low cigarette, low toxicity, fire-retardant purpose.
Description
Technical field
The invention belongs to cable material field, more particularly to a kind of 90 ° of PVC flame-retardant sheath materials and preparation method thereof.
Background technology
PVC sheath has thin soft, random bending fold, relative thickness, small volume, the simple, convenient disassembly of connection etc. excellent
Point, wire count and spacing can be arbitrarily selected, is more convenient on line, greatly reduce the volume of product, reduced production cost, carry
High efficiency, it is adapted to make data transmission cable in electric equipment or power transmission is used.And traditional PVC cable cover(ing)s due to
Itself dispensing is unreasonable, causes the sheath tensile strength that is manufactured into relatively low, poor toughness, unavoidably can will during the use of reality
Cable bend pulls drawing, so easily causes the rupture of sheath, can not continue to rise to being wrapped in the cable conductor inside sheath
It is shorter to protective effect, service life；Typically all it can increase flame-retardant sheath material in outer layer when power cable uses, to prevent cable
Fire occurs in accumulation amount of heat, and cigarette exactly caused by material burning, these cigarettes not only produce substantial amounts of Toxic
Matter, and people can be caused to suffocate, this is only principal element because of fire and dead, therefore studies with good flame-retardance energy
Cable protective sleeve is the important topic for preventing power cable fire.
