Description
Technical field
The utility model relates to tubing technical field, is specifically related to a kind of floor heating pipe.
Background technique
Floor heating pipe is a kind of tubing as hot water circuit flowing carrier, often by polyethylene, is made.The more floor heating pipe of use is al-plastics composite pipe in the market, and by polyethylene, crosslinked polyethylene and aluminium are compound to be made, according to the difference of interlayer structure, arrange the floor heating pipe structure that often has two kinds of structures, such as internal layer is polyethylene, centre is aluminium, and skin is crosslinked polyethylene; Or internal and external layer is crosslinked polyethylene, centre is the structure of aluminium, may be used to delivery, as floor heating pipe.Due to the thermal conduction characteristic of floor heating pipe,
The environment that has determined its use, for the environment with continuing thermal source and contact, exists thermal expansion or the cold and hot temperature difference to cause the hidden danger of explosion, and in the design of heating coil traditionally, do not relate to explosion-proof, therefore only pass through polyethylene,
The composite structure that crosslinked polyethylene and aluminium are made has limited the use occasion of floor heating pipe, has also affected the working life of floor heating pipe.
Model utility content
The purpose of this utility model is, a kind of explosion-proof plastic-aluminum PE-RT floor heating pipe is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Explosion-proof plastic-aluminum PE-RT floor heating pipe, comprises the internal layer that a metal mesosphere and PE-RT make, and it is characterized in that, is provided with an external protection outside described mesosphere, the external protection that described external protection adopts PE-RT to make.
The utility model solves the poor shortcoming of heating coil explosion-proof performance traditionally by the external protection that PE-RT is set makes, and has expanded the application area of tubing, has extended the working life of tubing.PE-RT is heat-proof polythene, be a kind of can be for the non-crosslinked polyethylene of hot-water line, adopt special MOLECULE DESIGN and synthesis technology to produce.It adopts the method for ethene and octene copolymer, by controlling the quantity of side chain and distributing, obtains unique structure of molecule, improves the heat resistance of PE.Because the existence of octene short-chain branch makes the large molecule of PE uncrystallizable in a flat crystal, but be applied in several crystal, having formed the connection between crystal, it has retained the good pliability of PE, high thermal conductivity and inertia make it resistance to pressure better simultaneously.
The thickness of described external protection is 0.2mm-1.2mm, preferably 0.2mm-1.0mm.
The mesosphere that described mesosphere adopts aluminium or aluminum alloy, copper or Cuprum alloy, lead or lead alloy material to make.
The mesosphere being made of a steel can also be adopted in described mesosphere.
The heat-fusing glue layer that make by a modified poly ethylene in described external protection and described mesosphere is combined together to form composite structure.
The heat-fusing glue layer that described heat-fusing glue layer preferably adopts maleic anhydride grafted polyethylene to make, is sticked together external protection and metallic intermediate layer by hot melt adhesive.Maleic anhydride grafted polyethylene is a kind of hot melt adhesive special that connects weldering aluminium-plastic composite pipe, preparation process connects the several maleic anhydride molecules of skill by the means of chemical reaction in sub polyethylene subchain, make product both there is poly good workability and other excellent properties, reactive and the strong polarity more again with maleic anhydride polar molecule, be beneficial to as coupling agent and reaction modifier use again, in plastics field, there is purposes widely.The characteristic of maleic anhydride grafted polyethylene makes to utilize its product making to have good physical and mechanical properties, and has good chemical-resistance, ageing-resistant performance and processibility, and polyethylene, aluminium, iron etc. are all had to higher bonding strength.
The set-up mode of described heat-fusing glue layer is co-extrusion or coating.
The thickness of described heat-fusing glue layer is 0.3mm-0.5mm, preferably 0.4mm.Heat-fusing glue layer applies the blocked up or thin easy adhesion effect that affects of mistake.
The ratio of the thickness of described internal layer, mesosphere, external protection is 1:1:1.
Between described internal layer and described mesosphere, adopt the hot melt adhesive that maleic anhydride grafted polyethylene is made to be connected.
Beneficial effect: owing to adopting technique scheme, the utlity model has good explosion-proof performance, solved the explosion hidden danger that heating coil exists traditionally, extended the working life of floor heating pipe, make product there is more wide application space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, explosion-proof plastic-aluminum PE-RT floor heating pipe, comprises the external protection 3 that internal layer 1, metal mesosphere 2 and PE-RT that PE-RT makes make.The thickness of external protection 3 is 0.2mm-1.2mm, preferably 0.2mm-1.0mm.Mesosphere 2 employing aluminium or aluminum alloy, copper or Cuprum alloy, lead or lead alloy, Steel material are made.The ratio of the thickness of internal layer 1, mesosphere 2, external protection 3 is 1:1:1.
