Magnesium hydroxide in the present invention, mica powder make CABLE MATERIALS be provided with fire prevention and fire-retardant function simultaneously; Bifenthrin in the present invention, toluene make product have excellent anti-ant function and anti-rat, through contrast use-testing, use the termite-proof and protection against rodents data of nylon 12 in material of the present invention and prior art as follows:
Material of the present invention is used to produce the cable of identical cable core with nylon 12, outermost jacket thickness is all 2mm, cable length is 2000 meters, parallel cloth is placed in the forest zone in Guizhou, in the cable running of material produce of the present invention 2 years, checks appearance weekly, only the 15th week time, in 1021st to the 1022nd meter, sheath has 3 ants and gnaw a little, and gnaw a degree of depth the most deeply for 0.3mm; And adopt the cable that nylon 12 is produced, lay in 2 years, check appearance weekly, from the 3rd week, different sites all occurred that ant gnaws a little over the entire length, during to the 26th week, in the 1021st to the 1026th meter, sheath had the hole that 8 ants gnaw, directly visible cable core; When the to the 45th to the 63rd week (winter), adopt the cable that nylon 12 is produced, in the 1021st to the 1026th meter, in the 1366th to the 1415th meter, in the 357th to the 513rd meter, in the 1565th to the 1612nd meter, there is the vestige that many places mouse gnaws, cable core place has been gnawed in some areas, in the 70th to the 100th week, the cable adopting nylon 12 to produce, has the vestige that the ant at nearly thousand places and mouse bit over the entire length; Therefore, the cable adopting material of the present invention to make, effectively prevent ant and mouse bites; On the basis of the above, cable enterprise is 125 kilometers of cables by material produce of the present invention, and be used in many ants and mouse area, use nearly 5 years, situation is normal, does not have the situation of being gnawed bad cable by ant and mouse and affecting electric power and communication to occur.
The adding of carbon black or titanium dioxide in the present invention, make material be provided with anti-ultraviolet function, product stands uviolizing for a long time and does not ftracture.
Cost of the present invention is only about 1/3 of nylon 12, because production rate during production cable greatly improves, has therefore greatly saved power consumption; This product, through life-time service, has no the yellowing phenomenon of material after producing.
Therefore, the present invention has following main beneficial effect: anti-ant and mouse performance is outstanding, anti-ultraviolet aging excellent property, there is electrical insulating property high, more heat-resisting, more corrosion-resistant, more resistance to steam, more oil resistant, more prevent fires, more fire-retardant, physical strength more advantages of higher; The present invention easily makes, and, thickness faster for the production of production rate during cable can control more accurately.
