Abstract
The utility model discloses a halogen and red phosphorus free flame retardant heat-shrinkable double-wall tube, which comprises a halogen and red phosphorus free flame retardant heat-shrinkable insulating layer disposed on the outer layer and a hot melt adhesive layer disposed on the inner layer. As the halogen and red phosphorus free flame retardant heat-shrinkable insulating layer is a flame retardant heat-shrinkable insulating layer mixing aluminum hydroxide and/or magnesium hydroxide and/or modified aluminum hydroxide and/or modified magnesium hydroxide, high molecular weight ammonium polyphosphate and/or phosphate esters flame retardant and/or melamine cyanurate and/or melamine pyrophosphate, the halogen and red phosphorus free flame retardant heat-shrinkable double-wall tube disclosed by the utility model does not produce a large amount of toxic and harmful gas during burning compared with a double-wall tube provided with a flame retardant insulating heat-shrinkable layer containing halogen or a halogen-free flame retardant heat-shrinkable layer containing red phosphorus, thereby being an environment-friendly halogen and red phosphorus free flame retardant heat-shrinkable double-wall tube.
Description
Technical field
The utility model relates to a kind of double-wall pipe, relates in particular to a kind of halogen-free non-red-phosphorus flame-retardant pyrocondensation double-wall pipe.
Background technology
Be mainly used in insulation protection at the beginning of the heat-shrink tube production, be widely used in now Aeronautics and Astronautics, boats and ships, automobile, household electrical appliances, communication, field of petrochemical industry, sealed damp-proof, waterproof, the effect such as shockproof are played by cable junction and branch.The pyrocondensation double-wall pipe comprises insulating barrier and hot melt adhesive layer, thereby PUR melting when being heated is bonded to double-wall pipe on the object to be protected, realizes the function of insulated enclosure.
Along with the raising of social progress and people's living standard, the thermal shrinkable flame retardant double-wall pipe has appearred, comprise fire retardant insulating shrink wrap layer and hot melt adhesive layer.The fire retardant insulating shrink wrap layer adopts Halogen fire proofing or the large Halogen of the employing amount of being fuming to contain red phosphorus combustion inhibitor usually.The overwhelming majority is to adopt organic bromide and antimony trioxide in the Halogen fire retardant insulating shrink wrap layer, produces a large amount of poisonous row evil gases during these material combustions, and the antimony trioxide price is very high simultaneously, also contains a large amount of heavy metals, does not meet RoHS Directive.Although and the red phosphorus combustion inhibitor that Halogen contains in the red phosphorus flame-retardant shrink wrap layer belongs to the halogen-free environment-friendly flame-proof material, in combustion process, produce the PH3 smog of a large amount of high poison; In the process of using, metal components and parts, electrode, coil etc. are had corrosiveness, in addition also can broken string, the hidden danger of quality such as loose contact, short circuit.
Yet, no matter adopt the double-wall pipe of Halogen fire retardant insulating shrink wrap layer or the double-wall pipe that Halogen contains the red phosphorus flame-retardant shrink wrap layer, in the process of using, all exist great potential safety hazard
The utility model content
The purpose of this utility model is to provide a kind of halogen-free non-red-phosphorus flame-retardant pyrocondensation double-wall pipe.
For achieving the above object, the utility model provides halogen-free non-red-phosphorus flame-retardant pyrocondensation double-wall pipe, comprises the hot melt adhesive layer that is positioned at outer field halogen-free non-red-phosphorus flame-retardant pyrocondensation insulating barrier and is positioned at internal layer.
