Description
Technical field
The present invention relates to CABLE MATERIALS technical field, more particularly to a kind of demagnetization water-proof anti-aging insulating materials.
Background technology
Low density polyethylene (LDPE) is as viscosity in process is relatively low and in drawing process has high fondant-strength same
When also have both not available for the conventional materials such as extremely strong resistance to chemical attack, acid and alkali-resistance, oil resistant, the nontoxic, long service life of light weight
It is advantage, therefore its range of application is throughout development and the various aspects of people's lives of national economy, such as electric wire, defeated
Send pipeline, automotive trim and construction material etc..But the oxygen index value of polyethylene is low, inflammable, and under field conditions (factors), with regard to energy
Conflagration, thermal discharge are big, worse with molten drop behavior, may cause spot fire, and also can when being thermally decomposed
A large amount of toxic and harmfuls are volatilized, people life property safety is threatened, and resistance to water is also poor, cause its application to be received
To restriction.So needing fire-retardant to which, and water resistance is improved, reduce the probability that fire hazard occurs, therefore which is carried out fire-retardant
Process is particularly important.
《The preparation of expansible fire retardant low-density polyethylene and its performance study》One literary author is poly- for current low-density
There is the technical barrier of poor water resistance during vinyl material halogen-free flameproof, using macromolecular carbon forming technology and encapsulation skill
The mode that art combines, development of new is water-fast halogen-free expanded flame-retardant LDPE Composite, wherein carbon forming agent select three
The APP of piperazine analog derivative CFA, dehydrating agent and foaming agent from Silica hydrogel parcel, this new low density polyethylene (LDPE) material
Material not only has higher thermal stability and fire resistance, while also overcoming the difficulty of poor water resistance.Although present invention solution
Low density polyethylene fire retardant of having determined is poor, the problem of poor water resistance, improves polyethylene safety coefficient in use, but
Be low density polyethylene (LDPE) however for high pressure field direct current cables in running, the low conductivity characteristic of polyethylene is caused
The space charge of accumulated inside is difficult to spread, and causes the Severe distortion of local field strength, especially when there is temperature in oepration at full load
During Gradient Effect, this phenomenon is even more serious, when surface of insulating layer local field strength reaches certain value, will cause shelf depreciation,
The insulation ag(e)ing phenomenon such as resinification, substantially reduces the service life of cable, to this improve polyethylene anti-flaming, water resistance it is same
When, improve its insulating properties and particularly seem urgent.
