Edge layer, therefore, cable is one of main application fields of insulating materials.Influence during cable use to environment is increasingly received
To the attention in the world, the developed country such as America and Europe, Japan has forbidden to use non-environmental protection type cable.
In recent decades, because EP rubbers has good combination property in itself, it has also become sent out in seven big synthetic rubber
A most fast kind of exhibition, field of cables is entered as excellent insulating materials.At present, EP rubbers has been acknowledged as resistance to 90
DEG C insulating materials and good High-Voltage Insulation rubber, completely or partially replace traditional butadiene-styrene rubber and butyl on many products
Rubber, consumption accounts for the second of electric wire synthetic rubber.But the anti-flammability of EP rubbers is poor, if rubber mass compounding is not
When, then the superior function of EP rubbers can not be not only played, and used it is also possible to limiting the effective of product, in addition, although
Electrical insulation capability is excellent in itself for EP rubbers, but it is after fire retardant is added, it is difficult to continue to keep good electrical property, to sum up respectively
Kind reason all constrains EP rubbers and preferably develops in field of cables.
Therefore, a kind of cable insulation using EP rubbers as major ingredient how is researched and developed, its can not only be kept excellent
Insulating properties, and possess good flame retardant effect, as people's problem demanding prompt solution.
The content of the invention
In consideration of it, the present disclosure provides a kind of insulation rubber of fire-retardant second third, at least to solve the insulation rubber of conventional second third
Skin, on the basis of its superior isolation is kept, it is impossible to the problems such as possessing good flame retardant effect.
The technical scheme that the present invention is provided, specifically, a kind of insulation rubber of fire-retardant second third, by weight, by following component
It is made：
100 parts of EP rubbers, 2.5 parts of vulcanizing agent, 3 parts of plasticizer, 1 part of age resistor, 160~180 parts of fire retardant, activator
