The insulating materials commonly used in cable has oil-paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc..In electrician
Technically, specific insulation is more than 109The material that Ω cm material is formed is referred to as insulating materials, that is, for making
Device is in the material that can electrically prevent electric current from passing through.Crosslinked polyethylene has excellent dielectric properties and mechanical performance, oneself
It is widely used in high pressure and super-pressure plastic insulating power cable.With super-pressure, extra-high voltage direct-current power transmission and transformation system
Develop, the insulation ageing problem in running is increasingly severe, and oneself turns into the major obstacle that insulated cable develops to super-pressure.
When the working field strength of insulating polymer reaches 1/10th of breakdown field strength, the power equipment to work long hours is exhausted
Poplar bundles can be caused in edge, reduce cable service life.The high voltage power cable insulating materials being made up of low density polyethylene (LDPE),
Gradual aging is influenceed by various aging actions in During Process of Long-term Operation, under the dielectric properties and mechanical performance that cause material
Drop.Voltage ageing, heat ageing, mechanical aging and Electrochemical Ageing can be divided into according to the classification of aging action.Wherein heat ageing is poly-
The main inducing of ethene cable insulation infringement, different thermal aging times and condition can cause the difference of polyethylene inner molecular structure
It is different, and then influence its space charge characteristic.
Research shows, under DC electric field effect, space charge is easily formed in polymer insulation, and space charge can make
Electric Field Distribution is distorted, and aggravates polymer insulation aging, and the aging of material result in the decline of material electric property.Polymer
Space-charge is mainly by the same polarity space charge and insulator that enter sunken carrier or transportable current-carrying of electrode injection
Organic or inorganic impurity ionized under electric field action caused by heteropolarity electricity.In order to suppress the formation of space charge, it is necessary to poly-
It is ethylene modified so as to change trap energy therein and distribution, change distribution of space charge, lower distortion probability, improve polymer
Dielectric properties, polymer insulation aging is reduced, and do not influence the processing characteristics of polymer simultaneously.

The content of the invention
Dielectric Properties at present on polyethylene/bentonite clay material are less, although bentonite has, cheap, performance is good
The features such as, but its surface has certain hydrophily, it is not easy to merged with polymer surfaces, therefore, present invention research passes through
It is bentonite modified, using its space layer chain structure, stable space layer chain is then formed with polyethylene and is combined, is reduced bentonitic
Surface free energy, the dissipation rate of charge migration speed and space charge is improved, to refuse electric field tight so as to suppress media interior
Distort again, suppress space charge accumulation, reduce space charge amount, improve distribution of space charge, improve charge transport, can be notable
Reduce the aging phenomenon of insulating materials.And because bentonite clay material has good heat resistance in itself, by it is modified can
Heat transfer inside polyvinyl alcohol material is want with the extraneous heat of barrier, the thermal diffusion of high temperature degradation is prevented, insulation can be improved
The resistance to elevated temperatures of material.
First, in order to improve bentonitic surface acidity, increase polar group, be modified using weak acid, increase is bentonitic
Specific surface area, gap structure distribution is improved, optimization layer chain space structure, increases lamella and chain length, is advantageous to and polyethylene knot
Close, so as to avoid only internal intercalation, Dispersion on surface can also be formed and polymerize, be advantageous to combining closely for the two；The present invention
The weak acid of use includes acetic acid, citric acid, malic acid, concentration 0.1-2mol/l, the acidic functionality that above-mentioned organic acid includes compared with
It is more, that is, destruction of the strong acid to bentonitic layer chain is avoided, it is gentle stable, but also certain three-dimensional effect can be formed, profit
In CO-, NH- isopolarity small molecule groups occupy active room, are configured to closely tie with bentonitic surface and interior layer link
Close, with dispersion space electric charge, can be advantageous to prevent the aggregation of space charge with low density polyethylene (LDPE) after mixing, so as to be advantageous to
It is anti-aging.
Polyimides is one of optimal high-molecular organic material of combination property, and high temperature resistant makes for a long time up to more than 400 DEG C
With temperature range -200~300 DEG C, no sharp melting point, high insulating property, 103 Dielectric constant 4.0 under Hz, dielectric loss is only
0.004~0.007, category F to H class F insulating material Fs.And with the characteristic such as low friction, wear-resistant, it is commonly used for protection materials.
Polyimides is to contain imide ring on main chain（-CO-NH-CO-）A kind of polymer, while there is CO-, NH-
Polar micromolecules group, bentonite is carried out to polyimide modified, the increase polar micromolecules degree of polymerization, further increase lamella sky
Between, and due to small polarity CO-, NH- presence adds the degree of polymerization of interior volume and surface polyethylene, and process is overcritical
After extraction, the expansion of piece sheaf space, density of material is reduced with polymer combination latter aspect, forms more light material, separately
On the one hand bentonitic surface free energy is reduced, improves the dissipation rate of electric charge, prevent space charge to gather, reduce insulation
The aging of material.Polyimides has good resistance to elevated temperatures in itself, and on the one hand bentonite is modified, and on the one hand may be used also
With play it is resistant to elevated temperatures a little, improve insulating materials system resistance to elevated temperatures, further optimize insulating materials.
