Abstract
The invention relates to flame-retardant filler for a cable, comprising a cross-linking polyethylene protective layer (1) as an external layer and an inner part (2) which is metal hydrate consisting of magnesium hydroxide, aluminum hydroxide and a sodium silicate binder. The invention has the benefits of further reducing the manufacturing cost of a flame-retardant cable and increasing the flame-retardant performance and the current-carrying capacity of the cable. The invention is the flame-retardant filler for the cable with economy, environmental protection and no public hazard.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of flame-retardant filler for cable.
Background technology
Flame-retardant filler for cable is a kind of packing material, is filled in the space between cable core, and purpose normally makes the cable rounding, and it has certain influence to the fire resistance of cable and the ampacity of cable.
Visible by Fig. 1: generally (treated polypropylene is torn rope to the cable of prior art by the fluff type flame-retardant filler with inserts; Has certain flame retardant effect; Can burn) or glass fiber gasket for packing 10 (gasket for packing self of glass fiber composition can not burn, but can not stop the burning of other combustible) composition; The former flame retardant effect is poor, and the latter endangers greatly operating personnel, is prone to cause respiratory tract and disease of skin, and the both exists the high deficiency of manufacturing cost.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of flame-retardant filler for cable, are intended to solve the above problems
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The present invention includes: outer is crosslinked polyethylene sheath and the inner metal hydrate of being made up of magnesium hydroxide, aluminium hydroxide and sodium silicate binder.
Compared with prior art, the invention has the beneficial effects as follows: further reduce the manufacturing cost of flame retardant cable, promote the fire resistance and the ampacity of cable; Be a kind of economy, environmental protection, nuisanceless type flame-retardant filler for cable.
Description of drawings
Fig. 1 is that the cable of prior art is used the inserts sketch map;
Fig. 2 is a sketch map of the present invention;
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
The present invention realizes through following technical scheme:
Visible by Fig. 2: as to the present invention includes: outer is the metal hydrate that crosslinked polyethylene sheath 1 and inside 2 are made up of magnesium hydroxide, aluminium hydroxide and sodium silicate binder;
The thickness of described crosslinked polyethylene sheath is between 0.2～0.4mm;
Said outer field external diameter is between 5～20mm.
Flame retardant effect of the present invention is best, is made up of metal hydrate, can discharge the crystallization water when receiving the flame invasion and attack, absorbs heat, can reduce the cable surface temperature, stops the burning of other combustible in the cable; This invention has good heat-conducting during the cable operate as normal, compares the raising that helps current-carrying capacity of cable with common inserts.
The proportioning of metal hydrate can be adjusted according to the fire-retardant requirement of cable among the present invention, mainly is the content of the adjustment crystallization water, and aluminium hydroxide, magnesium hydroxide all are that pressed powder is processed inserts through sodium silicate binder, is filled in the thin crosslinked polyethylene sheath.
