Electric wire is a kind of in order to transmit electricity（Magnetic）Energy, information and the wire product realizing electromagnetic energy conversion.Electric wire, as the main carriers of power transmission, is widely used in the aspects such as appliance equipment, illuminating line, household electrical appliance, and the quality of its quality directly influences construction quality and the security of the lives and property of consumer.Although a wires and cables industry simply supporting industry, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application is quite varied, is related to the industries such as electric power, building, communication, manufacture, all closely related with each department of national economy.Electric wire is also known as " tremulous pulse " and " neural " of national economy, it is conveying electric energy, transmission information and the various motors of manufacture, instrument, instrument, realize the indispensable basic equipment of electromagnetic energy conversion institute, be necessary basic product in following electrified, informationized society.
Current wires and cables industry constantly derives new product in the face of special occasions demand, such as fire resisting cable, flame-retardant cable, low smoke and zero halogen/low-smoke low-halogen cable, termite-proof, anti-mouse cable, oil resistant/cold-resistant/heatproof/wear-resisting cable, medical/agricultural/mining cable, thin-walled electric wire etc..
With the raising of people's safety consciousness, to performance requirement more and more highers such as the anti-flammability of electric wire, fire resistances, high flame-retardant electric wire and cable is the emphasis that current people compare concern to people.
Occur in fire incidents in many large-scale public arenas, be to suffocate because sucking electric wire (high polymer) discharges in burning, corrosive and poisonous dense smoke gas the reason most of personnel death.Wire cable material is carried out with fire-retardant and low cigarette process, and oneself fundamentally prevents from through being acknowledged as and reduces fire occurring, and reduces the Important Action of people's life and property loss.
Current electric wire divides from material and includes multiple electric wire such as PVC, PE, PP.PVC material has excellent mechanical and physical performance, pliability, chemical reagent-resistant performance, low price, and processing characteristics is excellent, is widely used on electric wire.But, contain halogen element in PVC, therefore, its discharge, corrosive and poisonous gas in burning.At present, gradually PVC is replaced using other materials.That electric wire discharges in burning, corrosive and poisonous dense smoke gas and suffocate, be not only the resin of its bulk composition as contained halogen element in PVC, also include some halogen containing flame-retardants of its use.People are in order to improve the anti-flammability of electric wire it will usually add some fire retardants in its material, and traditionally, these fire retardants are all halogen-containing materials.Research shows, halogen containing flame-retardant（HFR）Life and environment are harmful to, thus have made laws and limited the use of these materials, final goal is to terminate the use of most of this kind of products.For example, deca-BDE is a kind of HFR, and European Union has prohibitted the use of this material.
Ethylene-vinyl acetate copolymer (EVA), it has good flexibility, resistance to impact, environmental stress crack resistance within the scope of wider temperature, halogen-free flameproof is carried out as CABLE MATERIALS matrix to it using EVA, and improve the mechanical property of fire-retardant rear CABLE MATERIALS and make it meet the technical property requirements of low-smoke zero-halogen flame-retardant cable sheath, the popularization and application for fireproofing cable material without halide have very big value.
Meanwhile, electric wire, no matter be used in subsurface being also used on ground, all unavoidably can be affected by water and other corrosive substances, and then being affected its service life.
For the development of social economy, the property safety also for environmental protection and people and healthy it is necessary to develop a kind of waterproof anti-corrosion halogen-free high flame-retardant EVA electric wire.
