Abstract

The utility model provides a composite double-walled pipe formed by the thermal contraction and the thermal fusion of polymer. The utility model is double-walled composite pipe material composed of an outer layer 1 and an inner layer 2, wherein the outer layer 1 is radially shrank by heating; the inner layer 2 flows in a melting mode under heating shrinkage temperature; the utility model can be used for the connection and the branch of electric wires and cables and the insulation, the sealing, the water prevention and the sewage prevention of electronic components, and the utility model can also be sued for the corrosion prevention and the protection of pipelines. When the utility model is used, when heated to the shrinkage temperature of the outer layer 1, the outer layer 1 is radially shrank, and the inner layer flows in the melting mode; rough joint space and irregular surfaces are filled; the double-walled pipe is tightly shrank to a protective position to form a protective coating with good insulation, sealing and water prevention so as to improve the operational reliability.

Description

Thermal contraction and heat fusing compound double-wall pipe
The utility model belongs to the design of thermal contraction and heat fusing compound double-wall tubular construction.
Crosslinking with radiation thermal contraction polymer pipe has been widely used in fields such as electronics, electric power, household electrical appliances, automobile.As electric wire continue, the application of occasion such as insulation of terminal, protection, automotive line beam tube.But common heat-shrinkable tube; be anchored on by contraction and be insulated, protect the position; because macromolecule is loose and to a certain degree be directed at pine and overlap; particularly do not advise front surface and wire harness or component as electric wire continual-connecting-part tap; be difficult to form the purpose that good sealing reaches waterproof, protection against the tide, anti-environmental pollution corrosion, poor reliability.
The utility model purpose is a kind of thermal contraction of design and heat fusing compound double-wall pipe, and this double-wall pipe internal layer is the heat-shrinkable tube of the linear polyolefin of a kind of thermoplasticity or hot melt adhesive layer and outer thermal contraction layer composition double-walled composite construction.
The present invention compares with the ordinary hot draw at inner one deck linear thermoplastic's polyolefin or the PUR of increasing of heat-shrinkable tube, its major function, be when outer heat shrink, can melt-flow, the effect in space between filling and bonding pyrocondensation and the conductor is arranged when using like this, realize sealing, protection purpose.
Embodiment of the present utility model is described below in conjunction with the accompanying drawings, and Fig. 1 is the schematic diagram of thermal contraction and heat fusing polymer compound double-wall pipe.It is internal layer (2) formation by skin with heat shrink (1) and melt-flowable, skin is to be made of the polyolefine material that crosslinking with radiation and expansion are finalized the design, internal layer is by the linear polyolefin of thermoplasticity, or ethylene vinyl acetate copolymer PUR or polyamide hot formation.
The compound double-wall pipe of the utility model design continues as electric wire, the electric wire transition joint, the insulation at harness branch position, sealing and protection, the sealing protection of electronic component, pipeline anticorrosion, protection is the same with the ordinary hot draw convenient.Different is; when using the double wall heat draw; be heated to outer heat shrink temperature, skin begins to shrink, and the internal layer melt-flow; fill up rough joint space and do not advise positive gap; the compound double-wall pipe tightens in protected position, and between conductor and sheath, forms good insulation performance water-tight layer; remedy the deficiency during the ordinary hot draw is used, improved operational reliability greatly.
The compound double-wall heat-shrinkable tube of the utility model design is to integrate insulation, sealing, waterproof, damp proof, the novel thermal contraction element that protects.

Claims (1)

1. thermal contraction and heat are melted the compound double-wall pipe, it is characterized in that having the skin (1) of heat shrink and the internal layer (2) of melt-flowable constitutes, skin is to be made of the polyolefine material that crosslinking with radiation and expansion are finalized the design, internal layer is by the linear polyolefin of thermoplasticity, or ethylene vinyl acetate copolymer PUR or polyamide hot formation.
