Description
Technical field
Contain itrile group and perfluorocyclobutanearyl aryl-ether structure PAEK and its synthetic method the present invention relates to one kind, belong to
Polymeric material field.
Background technology
As the scope of power cable application is more and more wider, different use environments have different requirements, e.g., high temperature resistant, resistance to low
Temperature, oil resistant, tear-proof, fire-retardant etc..Particularly use condition is special, applied environment it is complicated in the case of, the need of special cable
Day aobvious protrusion is sought, reliability, durability to cable propose requirement higher.China Express Railway and urban track traffic are filled
Standby to quickly grow, requirement of the manufacturing enterprise to high ferro and urban rail dress cable in stock is towards ultra-thin-wall, high-temperature resistant, oil resistant high, high resistant
Combustion direction is developed.The insulating wall thickness of common thin-walled cable is in more than 0.3mm, and high-speed railway and urban track traffic equipment institute
The ultra-thin-wall insulated cable insulation wall thickness requirement for needing is 0.18mm.At present, cable industry produces the primary insulation material of thin-walled cable
Material is cross-linked polyolefin, and due to containing more fire retardant in the CABLE MATERIALS, insulaion resistance is smaller, and cable is easily breakdown, and
And the physical and mechanical properties of cable has many deficiencies, insulation wall can not be realized ultra-thin, it is difficult to the need for meeting manufacturing enterprise.Cause
This, production high-temperature resistant, oil resistant high, a key technology of the ultra-thin-wall insulated cable of high fire-retardance are exactly to study suitable cable
Material.
PAEK is a kind of aromatics thermoplastic special engineering plastic, with good physics and chemical property, thus often
By as CABLE MATERIALS.For example, CN103275458A provides a kind of Polyether-ether-ketocable cable material, by polyether-ether-ketone, polyester ether, gather
The mixing of phenylate, carbimide etc., improves the performance of CABLE MATERIALS, with intensity is higher, high abrasion, oil resistant high, electrical insulating property
It is good, and with the characteristic such as low cigarette, Halogen, fire-retardant, it is adapted to electricity thin-walled cable extrusion.CN105542390A provides a kind of resistance to thermal resistance
Combustion cable insulation material, by polyether-ether-ketone, chlorinated paraffin, alkyd resin, Lauxite, blanc fixe, asbestos, five bromoethyls
Benzene, mica powder, low density polyethylene (LDPE), calcinated argil, palm oil, glycerine, aminopropyl trimethoxysilane, bis-phenol, hypo-aluminum orthophosphate,
The mixing of polytetrafluoroethylene (PTFE), modified filler etc..Fire retardant in the cable material formula of the invention is by borate family fire retardant and phosphorus
Nitrogen combustion inhibitor compounding is formed, and adding a small amount of retardant synergist just makes the CABLE MATERIALS have good flame retardant effect and excellent suppression cigarette
Effect, the smoke density of the CABLE MATERIALS is low, poison exponent is low.And for example, patent CN105400131A provides a kind of special cable with again
Condensation material, the special cable composite is made up of following component：Polyether-ether-ketone, polyethylene, polyimides mix in proportion
As matrix material, using ethene-vinyl acetate copolymer is polymer-modified, molybdenum trioxide, magnesia are after coupling agent treatment
As flame-retardant additive, using cumyl peroxide as crosslinking catalyst, using silicon nitride crystal whisker as reinforcing agent, pass through
Melt blending forms composite, and it has preferable high temperature resistant property and the flame retardant effect for improving, and can realize bad working environments
Under stability do not reduce.However, formation homogeneous blend is more difficult between above-mentioned polymer, it is more multiple to preparation technology requirement
It is miscellaneous, and the auxiliary agent of its addition is more, undoubtedly increased product cost, reduces the reliability of cable.It can be seen that, it is existing to overcome
Many defects in technology, need a kind of high temperature resistant, reliability fire-retardant, that shielding system energy is good novel cable material high badly.
Make the electric wire that insulation and sheath material are made with fluoroplastics (such as polytetrafluoroethylene (PTFE), perfluoroethylene-propylene),
The oxygen index (OI) of fluoroplastics material is PE plastics more than 3 times, is 1.5 times of PVC plastic；Its combustion heat release amount is only four points of timber
One of, it is 1/7th of PE plastics；The cigarette produced under similarity condition is more much smaller than PVC material；Its combustion product is to equipment, instrument
The corrosivity of device is lower than PE, PVC material.In addition, its dielectric constant, dielectric dissipation factor, the letter of High Speed Transfer frequency band
The electric wire of number attenuation ratio other materials is all small, and physical and mechanical properties is better than other materials.
Poly (arylene ether nitrile) is the high performance engineering plastics that a class contains cyano group side base, with excellent high temperature resistant, corrosion-resistant, resistance to
Radiation, fire-retardant, physical and mechanical properties and fabulous dimensional stability in a balanced way.Due to drawing for highly polar cyano group side base (- CN)
Enter, on the one hand increased the dipole-dipole effect of molecule interchain, be conducive to obtaining heat resistance higher and mechanical strength
Meanwhile, the adhesive force of reinforced resin matrix；On the other hand, cyano group can be formed with higher resistance to as a potential crosslinking points
The network structure of hot property.
In sum, be incorporated into PAEK main chain for cyano group and perfluorocyclobutanearyl aryl-ether structure and prepare by the applicant
Cyano-containing and perfluorocyclobutanearyl aryl-ether structure PAEK so that the resinoid have simultaneously poly (arylene ether nitrile), polyether-ether-ketone and
The advantage of fluoroplastics.
