Abstract
The utility model discloses a polylactic electric-wire cable comprising polylactic restrictive layers, wrap layers, polylactic insulating layers, a cable core and anti-interference shielding layers, wherein the cable core is formed by intertwisting and connecting a main-wire core at the center and side-wire cores outside the main-wire core; the polylactic insulating layers are coated at all the outer surfaces of the main-wire core and each side-wire core; the wrap layers are coated on gaps between the main-wore core and the side-wire cores and the outer surface of the intertwisted cable core;and the outer surfaces of the wrap layers are orderly coated with the anti-interference shielding layers and the polylactic restrictive layers. The structure of the utility model is simple, and the polylactic electric-wire cable has the advantages of high thermal resistance, cold resistance, ageing resistance, acid resistance, easy bending, and the like. The polylactic electric-wire cable has theadvantages of large transmitting volume, small electric loss in the process of power transmission, and convenient arrangement and use. The polylactic electric-wire cable is widely applied to high-risebuildings, underground project locations, high-grade office buildings, hotels, mechanical industry, food industry, clothes industry, IT industry and other industry. By combining the characteristic ofpolylactic material, the polylactic electric-wire cable can not generate poisonous and harmful gas at high temperature.
Description
Technical field
The utility model relates to technical field of electric wires and cables, specifically relates to a kind of PLA electric wire.
Background technology
Many weeks, the tradition electric wire is by core and is wrapped in the outer field insulating sleeve layer of core and constitutes, the cable versatility of this type, cold-resistant, high temperature resistant, oil resistant and acid resistance are all undesirable, and the long-term back of using is easy to generate toxic gas, pollutant atmosphere under high-temperature condition.Therefore how to make electric wire can improve these performances, and reduce discharge of harmful gases and be beneficial to recovery and just become the problem that current electric wire technology industry is particularly paid close attention to.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, and a kind of high temperature resistant, cold-resistant, anti-aging, acid resistance, flexible PLA electric wire are provided.
For reaching the purpose of foregoing invention, the technical scheme that is adopted is: a kind of PLA electric wire, comprise the PLA restrictive coating, lapping layer, the PLA insulating barrier, cable conductor and anti-interference screen, wherein, described cable conductor is stranded the connecting and composing of side line core by the master core that is positioned at central authorities and the master core outside, the outer surface of described master core and every side line core all is enclosed with the PLA insulating barrier, gap between master core and the side line core and stranded after the cable conductor outer surface be enclosed with lapping layer, the outer surface of lapping layer is enclosed with anti-interference screen and PLA restrictive coating successively.The rounded structure of the shape of cross section of described master core.The shape of cross section of described side line core is sector structure.
In sum, PLA (PLA) is present up-to-date in the world environment-friendly type macromolecule material, " PLA " is called " environment amenable plastics " again, the PLA performance is better than polyethylene, in manufacturing process or in combustion process, produce discharging without any toxic and harmful, the amount of carbon dioxide that gives off is half of polythene material approximately, nontoxic, tasteless, no poison gas toxic smoke, and poly-lactic acid material can biodegradation advantage free from environmental pollution.The utility model is simple in structure, has high temperature resistant, cold-resistant, anti-aging, acid resistance, characteristics such as flexible.PLA electric wire transmission capacity is big, transmission of electricity process electricity decreases little, easy to install, be widely used in industries such as all kinds of skyscrapers, underground works place, senior office building, hotel and medical treatment, food, clothes, IT, in conjunction with the material behavior of PLA, can not produce poisonous and hazardous gas when making electric wire high temperature again.
