Description
Technical field
The present invention relates to a kind of cable material more particularly to a kind of high-low temperature resistant high strength PVC cable materials.
Background technology
It is basic resin, addition stabilizer, dioctyl phthalate, O-phthalic that PVC cable material, which is with polyvinyl chloride,
Sour diisodecyl ester, the inorganic fillers such as the plasticizer such as dioctyl terephthalate, trioctyl trimellitate (TOTM) and calcium carbonate, auxiliary agent
With the additives such as lubricant, the particle for squeezing out and preparing is mediated by mixture.
China's extremely frigid zones area accounts for about the 27.9% of territory total area, the areas such as northeast, Inner Mongol, northwest of energy abundance
High-cold regions are mostly in, and winter temperature is often less than -50 DEG C, how to improve the Low-Temperature Reliability of cable becomes urgently to be resolved hurrily
A key technical problem.The low-temperature impact brittle temperature of traditional PVC cable materials is much not achieved at -15 DEG C~-20 DEG C
Actual motion requirement.Cable insulate in the laid processes of extremely frigid zones and sheath suffers from damage, therefore these areas make
It is very necessary with low temperature resistant cable.With going deep into for upgrading urban and rural power grids, the demand of low temperature resistant PVC cable material can be got over
Come bigger.
In addition, polyvinyl chloride is poor to the stability of light, heat.Softening point is 80 DEG C, starts to decompose in 130 DEG C.It is being not added with
In the case of heat stabilizer, when 100 DEG C of polyvinyl chloride, starts to decompose, and 130 DEG C or more are decomposed faster.It is heated to decomposite releasing chlorine
Change hydrogen, (hydrogen chloride gas is toxic gas) makes its discoloration, by white → light yellow → red → brown → black.Sunlight
In ultraviolet light and oxygen can make polyvinyl chloride that photooxidation occur to decompose, thus the flexible of polyvinyl chloride is made to decline, last embrittlement.This
It is the reason of some PVC plastics will turn yellow, become fragile over time.
Such as a kind of a kind of low temperature resistant PVC cable material formula disclosed in Chinese patent literature, application publication number are
CN106519511A is made of the raw material below according to parts by weight:30~40 parts of polyvinyl chloride resin, ultra-low density polyethylene 10~
15 parts, 3~8 parts of β crystalline substances nucleating agent, 3~6 parts of polyolefin thermoplastic elastomer, 3~6 parts of octene ethylene copolymer, poly- glutaric acid the third two

4, diethylene glycol dibenzoate 14-18, color masterbatch 8-10, auxiliary agent 2-3;Polyvinyl chloride resin and ethene-vinyl acetate are total to by the CABLE MATERIALS
Polymers, which is blended, is used as resin binder, and is used as filler using modified treated cotton pulp, in conjunction with improvement processing performance work(
The auxiliary agent of effect and other auxiliary materials so that the more traditional polyvinyl chloride resin of invention CABLE MATERIALS shows more excellent when in use
Heat-proof combustion-resistant performance.But it is added to more expansible graphite in resin binder, although its be provided with it is stronger fire-retardant
Performance, but since expansible graphite is electric conductor, its insulation performance can be greatly reduced by being added in CABLE MATERIALS as filler,
Lead to the generation of the danger such as electric leakage electric shock.
