In the present invention, the monomer of propylene TFE copolymer material almost presents the alternately arranged structure of rule, and propylene monomer is subject to the tetrafluoroethylene protection of both sides, therefore, is highly stable in thermal characteristics, chemical property. In addition, ethylene tetrafluoroethylene copolymer has excellent thermotolerance, the pliability of extremely low temperature, extremely high water tolerance and acid-and base-resisting corrodibility, extremely high flame retardant resistance and excellent mechanical property, and excellent electrical insulation capability, stable temperature shrinkage performance; Therefore, it is little that whole material has gas-premeable, electrical insulating property height, the advantages such as steam heat-resisting, corrosion-resistant, resistance to, oil resistant.
In the present invention, adding of glass fibre, the viscosity of product is increased greatly, and friction resistance increases, and makes very easily to be attached on the cable core of cable during production, the thickness of the sheath producing cable is accurately controlled, and substantially increase production rate, the material of the present invention, S90 sheathing line produces cable, production rate reaches 60 ms/min, and the thickness of sheath accurately controls in the scope of 1.85 �� 0.03mm; Glass fibre add the physical strength that simultaneously improve material, make the tensile strength of material be greater than 28MPa, and the tensile strength of common sheath material and nylon cable material is only about 15MPa.
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 protection against rodents function, through contrast use-testing, it may also be useful in the material of the present invention and prior art, the termite-proof and protection against rodents data of nylon 12 are as follows:
The cable of identical cable core produced by the material of use the present invention and nylon 12, outermost jacket thickness is all 2mm, cable length is 2000 meters, parallel cloth is placed in the forest zone in Guizhou, and the cable running of material produce of the present invention, in 2 years, checks weekly appearance, only when the 15th week, in 1021st to the 1022nd meter, sheath has 3 ants and gnaws a little, and gnaw a degree of depth the most deeply for 0.3mm; And adopt the cable that nylon 12 is produced, and lay in 2 years, check weekly appearance, 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 ant at nearly thousand places and mouse to gnaw the vestige stung over the entire length; Therefore, adopt the cable made of material of the present invention, effectively prevent ant and mouse gnaws and stings; On above-mentioned basis, the material produce of cable enterprise the present invention 125 kilometers of cables, are used in many ants and mouse area, it may also be useful to nearly 5 years, situation was normal, does not have the situation gnawed bad cable by ant and mouse and affect electric power and communication to occur.
The adding of carbon black or titanium dioxide in the present invention, making material be provided with the function of uvioresistant, product stands uviolizing for a long time and does not ftracture.
The cost of the present invention is only about the 1/3 of nylon 12, owing to production rate greatly improves when producing cable, 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 useful effect: anti-ant and mouse performance is outstanding, anti-ultraviolet aging excellent property, have electrical insulating property height, steam, more oil resistant more heat-resisting, more corrosion-resistant, more resistance to, 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.
Through the test that applicant is repeated multiple times, as long as the cable material finding following formula can reach the object of the present invention: a kind of anti-ant CABLE MATERIALS, it is characterised in that it includes following starting material by weight: ethylene-tetrafluoroethylene copolymer 30��40 parts, propylene TFE copolymer 30��40 parts, 12��18 parts, glass fibre, magnesium hydroxide 2��4 parts, mica powder 2��4 parts, carbon black or titanium dioxide 2��4 parts, bifenthrin 1��3 part, toluene 3��5 parts.
