Abstract

The utility model relates to a fiber wound enhanced antibacterial PP-R pipe which comprises a PP-R outer layer and a PP-R inner layer; a nano antibacterial layer is compounded on the inner wall of the PP-R inner layer; a polypropylene fiber mesh-like layer is wound between the PP-R inner layer and the PP-R outer layer; and the outer side and the inner side of the polypropylene fiber mesh-like layer are respectively compounded with the PP-R outer layer and the PP-R inner layer through a hot melt adhesive layer 1 and a hot melt adhesive layer 2. The pipe has the benefits that the polypropylene fiber mesh-like layer is wound between the outer layer and the inner layer of the PP-R pipe, and the separation of the PPR inner and outer layers and the fiber mesh-like layer can be avoided by compounding the two hot melt adhesive layers; and in addition, pressure resistant strength of the pipe in high-temperature use is improved, and a layer of nano antibacterial material is compounded on the inner wall of the pipe through a co-extrusion technology, so as to improve the role of inhibiting the growth of bacteria of the pipe in a drinking water transportation process.

Description

Fiber twines and strengthens the antibacterial PP-R pipe

Technical field

The utility model relates to a kind of building pipe, relates in particular to a kind of fiber and twines enhancing antibacterial PP-R pipe.

Background technique

Medical research shows, the human basic reason that produces disease be since various harmful diseases and virus to due to the infringement of human body, formed some the bad custom of people's daily life, our complicated living environment of depending on for existence particularly, all might provide condition for various harmful germs and viral infringement to human body, the water everyday quoted of people particularly is because the low antibiotic property of conveyance conduit affects the healthy of people.

Chinese patent ZL200720072147.7 discloses a kind of antibiotic pipe, comprises PP-R (three type polypropylene) pipe, it is characterized in that, is provided with one deck silver series inorganic antibiosis layer by co-extrusion on the PP-R inner tube wall.Because PP-R tubing coefficient of linear expansion is big, thermal deformation resistant ability and longtime compressive strength are poor, can not be applied to the conveying of temperature flowing medium, when particularly using as the heating waterpipe, tubing is high temperature resistant and the longtime compressive strength poor performance, carries the potable water process can produce a large amount of bacteriums.

The model utility content

The purpose of this utility model provides a kind of fiber and twines enhancing antibacterial PP-R pipe, and is big to overcome existing P P-R tubing coefficient of linear expansion, can not be applied to the deficiency of the conveying of temperature flowing medium; And be compounded in the PPR pipe material inner wall by a kind of antibacterial plastic concentrate, can effectively suppress the effect of bacteria breed.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of fiber twines and strengthens the antibacterial PP-R pipe, comprise PP-R skin, PP-R internal layer, the inwall of described PP-R internal layer is compounded with the nano-antibacterial layer, be wound with the netted layer of polypropylene fiber between PP-R internal layer and the PP-R skin, the outside of the netted layer of described polypropylene fiber by the bonding layer of hot melt adhesive and PP-R outer compound be the inboard of the netted layer of one, described polypropylene fiber compound by the bonding layer of hot melt adhesive and PP-R internal layer be one.

The beneficial effects of the utility model are: twine the netted layer of a kind of polypropylene fiber and stop PPR internal and external layer and fibrous web-like pull-up from phenomenon by the bonding layer of composite double layer hot melt adhesive between PP-R outer tube layer and internal layer, make tubing in high temperature uses, increase compressive strength, improve tubing suppresses bacteria breed in the potable water course of conveying effect by the compound one deck nano anti-biotic material of co-extrusion technology on the pipe material inner wall.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is that the described fiber of the utility model embodiment twines the structure sectional view that strengthens the antibacterial PP-R pipe;

Fig. 2 is that the described fiber of the utility model embodiment twines the structural representation that strengthens the antibacterial PP-R pipe.

Among the figure:

1, PP-R skin; 2, PP-R internal layer; 3, nano-antibacterial layer; 4, the netted layer of polypropylene fiber; 5, the bonding layer of hot melt adhesive; 6, the bonding layer of hot melt adhesive.

Embodiment

Shown in Fig. 1-2, the described a kind of fiber of the utility model embodiment twines and strengthens the antibacterial PP-R pipe, comprise PP-R outer 1 and PP-R internal layer 2, the inwall of described PP-R internal layer 2 is compounded with nano-antibacterial layer 3, be wound with the netted layer of polypropylene fiber 4 between PP-R internal layer 2 and the PP-R skin 1, the outside of the netted layer 4 of described polypropylene fiber is compound by the bonding layer 5 of hot melt adhesive and PP-R outer 1 to be one; The inboard of the netted layer of described polypropylene fiber 4 is compound by the bonding layer 6 of hot melt adhesive and PP-R internal layer 2 to be one.

The utility model fiber twines the making of enhancing antibacterial PP-R composite pipe material and may further comprise the steps:

First one: enter antibiotic internal layer after nano-antibacterial masterbatch, PPR thermosol raw material, atactic copolymerized polypropene, drying, colour mixture are handled and be extruded into machine, PPR thermosol extruder, PPR internal layer and be extruded into machine, after extruding by three layers of composite dies;

Second step: the pipe vacuum sizing is cooled to the molding box cooling forming in entering;

The 3rd step: fiber is wrapped in interior tube-surface by the high temperature fiber Stetch Wrapping Machine;

The 4th step: enter the cooler bin moulding after extruding and entering the composite co-extruding mould coating by PPR hot melt adhesive extruder, the outer extruder of PPR, colo(u)r streak extruder;

The 5th step: tubing is made the finished product (fiber twines and strengthens the antibacterial PP-R composite pipe material) of designated length by entering cutting machine after the tractor traction.

Notice in the production process that each layer extruding and moulding requires suitable temperature, the desired rare density of certain thickness and braid graticule; Between PP-R pipe, PERT outer tube layer and internal layer, twine netted layer of a kind of novel polypropylene fiber and the bonding layer of hot melt adhesive, increase antibiotic layer at innermost layer and played antibiotic effect, the fibrous web-like layer has strengthened the toughness of tubing, has prolonged the working life of tubing, improves every performance of tubing.
