Description
Technical field
The present invention relates to a kind of electric wire and preparation method thereof, be specifically related to a kind of irradiation resistant non-halogen high fire-retardance EVA electricity
Line cable and preparation method thereof.
Background technology
Electric wire is a kind of in order to transmit electricity (magnetic) energy, information and the wire product realizing electromagnetic energy conversion.Electric wire electricity
The main carriers that cable transmits as electric power, is widely used in the aspects such as appliance equipment, illuminating line, household electrical appliance, its quality
Quality directly influences the security of the lives and property of construction quality and consumer.Although a wires and cables industry simply supporting row
Industry, but in occupation of the output value of China's electrician trade 1/4.Its product category is numerous, and range of application is quite varied, relate to electric power,
Build, communicate, the industry such as manufacture, the most closely related with each department of national economy.Electric wire is also known as national economy
" tremulous pulse " and " neural ", be conveying electric energy, transmission information and manufacture various motor, instrument, instrument, it is achieved electromagnetic energy is changed
Indispensable basic equipment, is basic product necessary in following electrification, informationized society.
Current wires and cables industry is in the face of the special occasions demand constantly derivative product made new advances, such as fire-resistant cable, fire-retardant
Cable, low smoke and zero halogen/low-smoke low-halogen cable, mouse cable termite-proof, anti-, oil resistant/cold-resistant/heatproof/wear-resisting cable, medical/agriculture
With/mining cable, thin-walled electric wire etc..
Along with the raising of people's safety consciousness, people are to performance requirements such as the anti-flammability of electric wire, fire resistances increasingly
Height, high flame-retardant electric wire and cable is the emphasis that current people compare concern.
In the public arena breaking out of fire accident that many is large-scale, the reason of most of personnel deaths is because sucking electric wire electricity
Cable (high polymer) burning time discharge, corrosive and poisonous dense smoke gas and suffocate.Wire cable material is carried out
Fire-retardant and low cigarette processes oneself and occurs through being acknowledged as fundamentally preventing and reduce fire, reduces people's life and property loss
Important Action.
Current electric wire divides from material and includes the 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 are excellent, are widely used in electric wire electricity
On cable.But, containing halogen element in PVC, therefore, it is discharge, corrosive and poisonous gas when burning.At present,
The most gradually employing other materials replaces PVC.That electric wire discharges when burning, corrosive and poisonous dense smoke
Gas and suffocate, be not only containing halogen element in the resin such as PVC of its bulk composition, also include that its some used Halogen hinders
Combustion agent.People are in order to improve the anti-flammability of electric wire, it will usually add some fire retardants in its material, and traditionally, this
A little fire retardants are all halogen-containing materials.Research shows, halogen containing flame-retardant (HFR) is to life and bad environmental, because of legislation limit
Making the use of these materials, final goal is to terminate the use of this series products of great majority.Such as, deca-BDE is a kind of HF
R, European Union has prohibitted the use of this material.
Ethylene-vinyl acetate copolymer (EVA), it has good flexibility, resistance to punching within the scope of wider temperature
Hitting property, environmental stress crack resistance, carry out halogen-free flameproof as CABLE MATERIALS matrix to it using EVA, and improve fire-retardant rear cable
The mechanical property of material makes it meet the technical property requirements of low-smoke zero-halogen flame-retardant cable sheath, for low-smoke non-halogen flame-retardant electricity
The popularization and application of cable material have the biggest value.
Common halogen-free flameproof cable material can crack after by high dosage irradiation, under causing material property serious
Fall, therefore, it is necessary to improve the radiation-resistant property of wire cable material.
For socioeconomic development, also for protection environment and the property safety of people and healthy, it is necessary to grind
