Description
Technical field
The present invention relates to a kind of electric wire and preparation method thereof, be specifically related to a kind of purple light cross-linking low-smoke halogen-free high flame retardant EVA 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.
Current wires and cables industry is in the face of the continuous derivative product making new advances of special occasions demand, as fire-resistant 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.
Along with the raising of people's awareness of safety, people are more and more higher to performance requirements such as the anti-flammability of electric wire, fire resistances, and high flame-retardant electric wire and cable is the emphasis that current people relatively pay close attention to.
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 when 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.
Current electric wire comprises the multiple electric wires such as PVC, PE, PP from material minute.PVC material has good mechanical and physical performance, pliability, chemical reagent-resistant performance, low price, and processing characteristics is excellent, is widely used on electric wire.But, in PVC, contain halogen element, therefore, it is discharge, corrosive and poisonous gas when burning.At present, employing other materials gradually replaces PVC.Electric wire is at when burning dense smoke gas that discharge, corrosive and poisonous and suffocating, be not only the resin of its main body composition as contained halogen element in PVC, also comprise some halogen containing flame-retardants of its use.People, in order to improve the anti-flammability of electric wire, conventionally can in its material, add some fire retardants, and traditionally, these fire retardants are all halogen-containing materials.Research shows, halogen containing flame-retardant (HFR) is harmful to life and environment, and because legislation limits the use of these materials, final goal is the use that stops most of these series products.For example, deca-BDE is a kind of HFR, and European Union has banned use of this material.
Ethylene-vinyl acetate copolymer (EVA), it has good flexibility, resistance to impact, environmental stress crack resistance in wider temperature range, the EVA of usining carries out halogen-free flameproof as CABLE MATERIALS matrix to it, and the mechanical property of improving fire-retardant rear CABLE MATERIALS makes its technical property requirements that meets low-smoke zero-halogen flame-retardant cable sheath, for applying of fireproofing cable material without halide, there is very large value.
At present, the crosslinked main electron beam irradiation mode that adopts of low-smoke halogen-free flame-retardant isolating material for electric wire, its shortcoming is that investment is large, easily produces electron trap (electronics gathers), has electrostatic effect, environmental-protection and operating maintenance difficulty etc.Owing to there is no suitable alternative cross-linking method, in low-smoke halogen-free flame-proof cable material field, electron beam to irradiate crosslinked is dominate in existing crosslinking technological still.
For socioeconomic development, also, for protection of the environment and people's property safety and healthy, be necessary to develop a kind of purple light cross-linking low-smoke halogen-free high flame retardant EVA electric wire.
