Description
Technical field
The present invention relates to a kind of electric wire and preparation method thereof, be specifically related to a kind of high-effect rat-and-ant proof electric wire and preparation method thereof.
Background technology
Electric wire is a kind of in order to transmit electricity (magnetic) energy, information and the wire product of realizing electromagnetic energy conversion.Electric wire, as the main carriers of electric power transfer, is widely used in the aspects such as appliance equipment, illuminating line, household electrical appliance, and the quality of its quality directly has influence on project quality and consumer's the security of the lives and property.Although wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application is very extensive, relates to the industries such as electric power, building, communication, manufacture, all closely related with each department of national economy.Electric wire is also called as national economy " artery " and " nerve ", the various motors of transmission of electric energy, transmission of information and manufacture, instrument, instrument, realizing the indispensable basic equipment of electromagnetic energy conversion, is necessary basic product in following electrification, informationized society.
In modern industry process; electric energy and information dependence are increased; electrical network and the large capacity of information network forward and high density future development; once be damaged; cause sometimes serious economic loss; make troubles to our life, thereby should take certain measure to protect cable, ensure the unimpeded for a long time of electrical network and wired information network.The animal of destroying cable is more, and what wherein harm was comparatively serious is mainly termite, mouse.They destroy cable is not for edible cable material, but relevant with its life habit.
In order to protect electric wire; wires and cables industry also derives termite-proof, anti-mouse cable at present; termite-proof, anti-mouse cable in the past; normally adopt PVC as basis material; in the outer wall materials of electric wire, add anti-termite agent as chloride alicyclic ring or heteroaromatic compounds such as dieldrite, drinox, lindane, Nirans; these compounds have very strong penetrating odor and have also toxic; in the harm of control termites, mouse; the health of environmental pollution and human body has also caused harm, therefore needs to develop the medicine of some environment-friendly types.Termite-proof, anti-mouse cable in the past, also puts layer of metal sheath at the outer wall of electric wire conventionally, but these metallic sheaths can not be bending, for long-distance transport has brought inconvenience.
Meanwhile, the PVC material that cable adopts in the past, although cost is lower, contains halogen element in PVC, and therefore, it is discharge, corrosive and poisonous gas in the time of burning.At present, employing other materials gradually replaces PVC.
Along with the raising of people's awareness of safety, people require more and more higher to the anti-flammability of electric wire, and flame-retardant and fire-resistant wire and cable is the emphasis that current people relatively pay close attention to.In all spectra of electric power application, the fire line of electric wire is ensureing to play very important effect aspect the integrity of electrical system and validity.
In many large-scale public arena breaking out of fire accidents, because sucking, electric wire (high polymer) discharges the reason of most of personnel's death in the time burning, corrosive and poisonous dense smoke gas suffocates.Wire cable material is carried out to fire-retardant and low cigarette processing, and oneself fundamentally prevents from and reduces fire occurring through being acknowledged as, and reduces the Important Action of people's life and property loss.
For socioeconomic development, also for protection of the environment and people's property safety and healthy, be necessary to develop a kind of high-effect rat-and-ant proof electric wire with low-smoke non-halogen flame-retardant of environment-friendly type.
