Abstract

The utility model discloses an antibiotic PP of high performance R stable state pipe, including inlayer, intermediate level and skin, its characterized in that, the intermediate level cladding is in the outside of inlayer, and the external sheath is equipped with first tie coat in the outside in intermediate level between inlayer and intermediate level, be equipped with the second tie coat between intermediate level and skin, and the inlayer is the antibiotic masterbatch of silver ion. The utility model relates to a rationally, can effectually avoid increasing the bacterial growing of inlayer, sanitary performance is good, has effectively ensured the pipe -line system flow simultaneously.

Description

A kind of high-performance antibiosis pp-r steady state pipe

Technical field

This utility model is related to steady state pipe technical field and in particular to a kind of high-performance antibiosis pp-r steady state pipe.

Background technology

Traditional fine work pp-r covers aluminum steady-state tube and generally comprises outer layer and internal layer, is provided with centre between internal layer and outer layer Layer, outer layer adopts pp-r, and internal layer is pp-r, and intermediate layer processes aluminium lamination for inner face coating glue through special punching, in aluminum After layer is combined with inner tube, it is coated with glue and bonds with outer layer, thus the fine work pp-r being shaped to five-layer structure covers aluminum steady-state tube.

Outer layer plays protection aluminium lamination effect, and the outside of outer layer is coated with thermo oxidative aging layer, plays and prevents thermo-oxidative ageing Effect, glue layer play bond plastic and aluminium lamination effect, internal layer be main bearing course.Several are uniformly offered saturating on intermediate layer Pore, such that it is able to make vapor permeate from inside to outside, avoids bubbling phenomenon beneficial to discharging vapor, further increases this The service life of steady state pipe.Ensure bonds well while internal layer can also be made to contact with each other with outer layer local, increased interior, The switching performance of outer layer.Although fine work pp-r covers aluminum steady-state tube and has that linear expansion coefficient is little, uvioresistant, ectonexine heat seal strength High, no bubbling, long service life the advantages of, but because its aluminum skin is processed through punching, especially in applied at elevated temperature, oxygen holds very much Easily pass through hole in the middle of inside and outside pp-r layer and aluminium strip to enter in pipeline, lead to easy breed bacteria in pipe, and then affect system stream Measure, bring hygienic issues etc..

But it is directed to the deficiencies in the prior art, developer is necessary that development one kind is reasonable in design, it is interior effectively to avoid The bacteria breed of layer, sanitation performance is good, simultaneously the effective guarantee fine work antibacterial pp-r steady state pipe of tubing flow.

Utility model content

The purpose of this utility model is the shortcoming and defect in order to overcome prior art, provide reasonable in design, can be effective Avoid increase the bacteria breed of internal layer, sanitation performance is good, and a kind of high-performance of effective guarantee tubing flow resists simultaneously Bacterium pp-r steady state pipe.

A kind of high-performance antibiosis pp-r steady state pipe, including internal layer, intermediate layer and outer layer；Described intermediate layer is coated on internal layer Outside, external sheath, in the outside in intermediate layer, is provided with the first tack coat between internal layer and intermediate layer, intermediate layer and outer layer it Between be provided with the second tack coat, described internal layer be silver-ion antibiotic masterbatch.

Further, described internal layer is pp-r layer, and described intermediate layer is aluminium lamination, and described outer layer is pp-r layer.

Further, described aluminium lamination is the aluminium lamination uniformly offering several air-vents above.

Further, described first tack coat and the second tack coat are PUR.

Further, the outside of described outer layer is coated with evoh(ethylene-vinyl alcohol copolymer).

Further, the outside of described outer layer is coated with thermo oxidative aging layer, the outside cladding of described thermo oxidative aging layer There is uvioresistant layer.

The beneficial effects of the utility model are:

1. internal layer be silver-ion antibiotic masterbatch so as to processing characteristics and physical and mechanical property are consistent with common ppr, Excellent with the adhesive property of outer layer, increase the antibiotic property of internal layer simultaneously, strengthen steady state pipe sanitation performance, simultaneously effective guarantee Tubing flow；

2. outer layer is that possess thermo oxidative aging and photooxidative aging performance uvioresistant layer, can effectively reduce steady state pipe Rate of ageing, further increase the service life of this steady state pipe；

3. the first tack coat and the second tack coat are PUR, ensure that this steady state pipe in 60 c water using PUR When under temperature, adhesive strength does not occur substantially to decay, and improves the adhesive strength between each layer.

Brief description

Fig. 1 is structural representation of the present utility model.

In accompanying drawing: 100, internal layer, the 200, first tack coat, 300, intermediate layer, the 400, second tack coat, 500, outer layer.

Specific embodiment

With reference to embodiment, specific embodiment of the present utility model is described in further detail:

As shown in figure 1, a kind of high-performance antibiosis pp-r steady state pipe, including internal layer 100, intermediate layer 300 and outer layer 500；In Interbed 300 is coated on the outside of internal layer 100, and outer layer 500 is coated on the outside in intermediate layer 300, in internal layer 100 and intermediate layer 300 Between be provided with the first tack coat 200, be provided with the second tack coat 400 between intermediate layer 300 and outer layer 500, internal layer 100 be silver from Sub- antibacterial plastic concentrate.

Internal layer 100 is pp-r layer, and intermediate layer 300 is aluminium lamination, and outer layer 500 is pp-r layer；Aluminium lamination is uniformly to offer above The aluminium lamination of several air-vents, the first tack coat 200 and the second tack coat 400 are PUR, and the outside of outer layer 500 is coated with Evoh(ethylene-vinyl alcohol copolymer).

The above is only preferred implementation of the present utility model it is noted that ordinary skill people for this area Member for, on the premise of without departing from this utility model know-why, some improvements and modifications can also be made, these improve and Retouching should also be as being considered as within protection domain of the present utility model.
