Description
Technical field
The present invention relates to fire proofing material field, specifically a kind of fire proofing.
Background technique
As the flame retardant property of the raising that people require electrical safety, cable is increasingly concerned by people, quality is high
The low life security for directly influencing user.Predominantly its structure of common cable mainly includes conductor currently on the market, insulation
Body, common filler material, sheath.The material of insulator generallys use cross-linked polyethylene insulating material.Since the material is inflammable, and absolutely
Edge external week is without good protective layer, therefore the flame retardant property of cable is bad.The Halogen of cable, nontoxic, low-heat release and height are certainly
If putting out characteristic becomes target -- the European Union B for the good horse that colleague in the industry becomes1The wire examination method of grade flame retardant cable is to measure this target to be
The mark post of no leap.Its structure of flame retardant cable includes conductor, silicon rubber insulation, common filler material, band, sheath, and resistance to combustion is anti-
Fire bed and fire retardant jacket.The material of resistance to combustion fireprotection layer is mica tape, silicone band or metal armor layers.The material of fire retardant jacket is resistance
Fire polyolefin.Domestic existing fire proofing at present, the sample of cable that flame-retarded technology is constructed are most of to be difficult to through European Union B1Grade
The examination of flame retardant cable.As the cross-linking polyethylene materials of cable insulation, electric strength is high, and manufacture craft is good, but inflammable, and heat is released
High-volume big, common behave is to wrap multi-layer metal belts on cable or set with the more thick and heavy material of resistance to combustion things thus, outer to weaken
The attack of boundary's flame high temperature, but this increases cost of manufacture and manufacture difficulty again.
