Abstract
The utility model discloses a crowd altogether for five layers and warm up delivery pipe with hindering oxygen polybutylene, including once altogether crowded fashioned polybutylene cross water layer, first glue film, hinder the oxygen layer, second glue film and polybutylene protective layer, the polybutylene is crossed water layer, first glue film, is hindered the oxygen layer, second glue film and polybutylene protective layer ab intra outwards set gradually, hinder the oxygen layer and adopt the ethylene -vinyl alcohol copolymer, through using the adhesive to bond the polybutylene protective layer respectively to cross the water layer with the polybutylene, hinder the function that can realize hindering oxygen in the oxygen layer with inboard hindering the oxygen layer outside, the quality that warms up the water not influenced with ensureing, will hinder the oxygen layer and set up between two -layer polybutylene, can directly adopt the hot melt to connect when the installation butt joint, and underfloor heating system's steady operation, increase of service life are ensured to convenient the construction.
Description
Technical field
This utility model relates to floor heating special feed pipe technical field, particularly relates to a kind of five-layer co-squeezing resistance oxygen polybutene floor heating feed pipe.
Background technology
Floor heating pipe refers to that being used as low-temperature water heating in Low Temperature Hot Water Floor Radiant Heating System (abbreviation floor heating) circulates a kind of tubing of carrier, and the kind of the floor heating pipe used in the market has: XPAPR: crosslinking folder aluminum pipe；PE-X: crosslinked polyethylene 1；PAP: PAP 2；PP-B: impact resistance COPP (Korea S was once referred to as PP-C)；PP-R: atactic copolymerized polypropene；PB: polybutene (thermostable tubing)；PE-RT:: refractory polyethylene, but the most all there is different defects in above-mentioned several tubing, such as PE-X tubing does not has thermoplastic property, can not be with the method connection of sweat soldering and reparation etc., floor heating pipe is that solidification is arranged in the middle of floor during housing construction, it is used for the life-span and heat stability has high requirement, but also need convenient construction and reparation, although three currently used strata butylene resistance oxygen feed pipes disclosure satisfy that the requirement of service life and heat stability, but owing to the oxidation prevention layer of this kind of tubing is positioned at tube surfaces, operation just can be carried out after needing to peel off the oxidation prevention layer of interface position in fusion process, be inconvenient to construct.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of five-layer co-squeezing resistance oxygen polybutene floor heating feed pipe; adhesive the most bonding polybutene protective layer and polybutene is used to cross water layer with inner side outside oxidation prevention layer; oxidation prevention layer is capable of hindering the function of oxygen; guarantee that the quality of floor heating water is unaffected; oxidation prevention layer is arranged between two-layer polybutene, can directly use hot-melt adhesive paste, convenient construction when installing docking; guarantee the stable operation of ground heating system, increase the service life.
For solving above-mentioned technical problem; technical solution adopted in the utility model is: a kind of five-layer co-squeezing resistance oxygen polybutene floor heating feed pipe; polybutene including a coextrusion mold crosses water layer, the first glue-line, oxidation prevention layer, the second glue-line and polybutene protective layer; described polybutene is crossed water layer, the first glue-line, oxidation prevention layer, the second glue-line and polybutene protective layer and is set gradually from inside to outside, and described oxidation prevention layer uses ethylene-vinyl alcohol copolymer.
Described polybutene is crossed the thickness of water layer, oxidation prevention layer and polybutene protective layer and is 0.5-0.6 millimeter.
Described polybutene protective layer outer wall nominal diameter is 20mm.
Use and have the beneficial effects that produced by technique scheme: by using adhesive the most bonding polybutene protective layer and polybutene to cross water layer with inner side outside oxidation prevention layer; oxidation prevention layer is capable of hindering the function of oxygen; guarantee that the quality of floor heating water is unaffected; oxidation prevention layer is arranged between two-layer polybutene; hot-melt adhesive paste can be directly used when installing docking; convenient construction, it is ensured that the stable operation of ground heating system, increases the service life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
In the accompanying drawings: 1, water layer crossed by polybutene；2, the first glue-line；3, oxidation prevention layer；4, the second glue-line；5, polybutene protective layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Elaborate a lot of detail in the following description so that fully understanding this utility model, but this utility model can also use other to be different from alternate manner described here to be implemented, those skilled in the art can do similar popularization in the case of this utility model intension, and therefore this utility model is not limited by following public specific embodiment.
As shown in Figure 1; the utility model discloses a kind of five-layer co-squeezing resistance oxygen polybutene floor heating feed pipe; polybutene including a coextrusion mold crosses water layer the 1, first glue-line 2, oxidation prevention layer the 3, second glue-line 4 and polybutene protective layer 5; described polybutene is crossed water layer the 1, first glue-line 2, oxidation prevention layer the 3, second glue-line 4 and polybutene protective layer 5 and is set gradually from inside to outside; the thickness that described oxidation prevention layer 3 uses ethylene-vinyl alcohol copolymer, described polybutene to cross water layer 1, oxidation prevention layer 3 and polybutene protective layer 5 is 0.5-0.6 millimeter；Described polybutene protective layer 5 outer wall nominal diameter is 20mm.
In concrete application process, polybutene feed pipe disclosed in this utility model uses five-layer co-squeezing technological forming, using double compound unit die head co-extrusion in forming process, oxidation prevention layer uses EVOH, and is arranged on by oxidation prevention layer in the middle of two-layer polybutene layer, direct hot melt in docking operation, it is easy to construction, although be more difficult to processing relative to existing three-layer co-extruded polybutene feed pipe, but once constructed and got final product life-time service, ensure that the stable operation of ground heating system, increase the service life.
In a word; this utility model is outside oxidation prevention layer and inner side uses adhesive the most bonding polybutene protective layer and polybutene to cross water layer; oxidation prevention layer is capable of hindering the function of oxygen; guarantee that the quality of floor heating water is unaffected; oxidation prevention layer is arranged between two-layer polybutene, can directly use hot-melt adhesive paste, convenient construction when installing docking; guarantee the stable operation of ground heating system, increase the service life.
