Abstract
The invention discloses a formulation of a composite material of a protective layer of an underground power cable. According to the technical scheme, a dual-sheath unit contains an inner insulated sheath and an outer protective sheath. The formulation of the insulated sheath is as follows: 50% to 80%of Teflon, 10% to 20% of a plasticizer, and 15% to 25% of a stabilizing agent; and the formulation of the protective sheath is as follows: 10 to 30% of spider thread fibers, 30 to 60% of chinlon, and 20 to 50% of spandex. According to the invention, the material is prepared scientifically. On the basis of the formulation, the inner insulated sheath has the excellent insulating performance and the outer protective sheath has good wearing-resistance, corrosion-resistant, and anti-degradation performances and high strength.
Description
Technical field
The present invention relates to a kind of formula, especially a kind of formula of down-hole power cable covering composite material.
Background technology
Power cable is the cable for transmitting and distribute electric energy, and power cable is usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises' in-line power and power transmission line under crossing river seawater.In power circuit, cable proportion increases just gradually.The basic structure of power cable is made up of the protective layer outside core and core, based on the requirement of wear resistant corrosion resistant in the feature of power cable " interior conduction; external insulation " and practical application, the effect of protective layer is isolated from each other between core and the earth and out of phase core on electrically, ensures power delivery; And protection power cable is from the intrusion of introduced contaminants and moisture, and prevent external force from directly damaging power cable, there is wear resistant corrosion resistant, degradation-resistant feature usually.
China Patent Publication No. CN104425074A, publication date on March 18th, 2015, the name of innovation and creation is called the two protective cover material formula of a kind of down-hole power cable, that application discloses the two protective cover material formula of a kind of down-hole power cable, its weak point is that oversheath adopts polyvinyl chloride, and polyvinyl chloride wearing-resistant is not enough; Anti-degradation capability is poor.
Summary of the invention
For solving an above existing difficult problem, the invention discloses a kind of formula of down-hole power cable covering composite material, its technical scheme is specific as follows:
Described protective layer is divided into inner insulating sleeve and outside protection sheath, wherein,
The formula of insulating sleeve is:
Polytetrafluoroethylene 50 ~ 80%
Plasticizer 10 ~ 20%
Stabilizer 15 ~ 25%
The formula of protection sheath is:
Spider's thread fiber 10 ~ 30%
Polyamide fibre 30 ~ 60%
Spandex 20 ~ 50%
Further,
The formula of insulating sleeve is:
Polytetrafluoroethylene 55 ~ 75%
Plasticizer 12 ~ 18%
Stabilizer 17 ~ 23%
The formula of protection sheath is:
Spider's thread fiber 15 ~ 25%
Polyamide fibre 35 ~ 55%
Spandex 25 ~ 45%
Further,
The formula of insulating sleeve is:
Polytetrafluoroethylene 60 ~ 70%
Plasticizer 14 ~ 16%
Stabilizer 18 ~ 22%
The formula of protection sheath is:
Spider's thread fiber 18 ~ 22%
Polyamide fibre 40 ~ 50%
Spandex 30 ~ 40%
Polytetrafluoroethylene: the feature with antiacid alkali resistant, anti-various organic solvent, is dissolved in all solvents hardly.Meanwhile, polytetrafluoroethylene has resistant to elevated temperatures feature, and its coefficient of friction is extremely low, has lubrication;
Spider's thread fiber: the physicochemical property of spider's thread fiber has obviously advantage, in mechanical strength, spider's thread fiber and the highest carbon fiber of intensity and fine Aramid, Kelve equal strength of high-strength conjunction are close, but its toughness is obviously better than above-mentioned several fiber; Spider's thread fiber elasticity as rich as Croesus, a diameter only has the spider silk of ten thousand/millimeter, can extend more than twice and just can break, and is known anti-wear performance best material;
Polyamide fibre: polyamide fibre intensity is high, resistance to wear good, its intensity and resistance to wear occupy first of all fibres;
Spandex: spandex has special elastic performance, and strength ratio rubber latex thread is high 2 ~ 3 times, line density is also thinner, and more chemically-resistant degraded; The resistance to acids and bases of spandex, sea water resistance, resistance to wear are all better.
Beneficial effect: compatibility science of the present invention, the insulating sleeve of the described inside adopting formula of the present invention to make has fabulous insulation property, and the protection sheath of outside has excellent resistance to wear, corrosion resistance, anti-degradability and good intensity.
