Background technique

The PP-R pipe of supply in the market because its advantage such as corrosion-resistant, in light weight is used widely, wherein also is used for heating pipe and refrigerant pipe, but this pipe is because its thermal conductivity is higher, and heat insulation effect is not good enough, in order to improve its thermal insulation property, adopt measures such as on-the-spot coating thermal insulation layer in construction, its result makes installing engineering complicated, not only takes a lot of work but also time-consuming, and cost is also high, labor intensity is also big, and the performance of insulation is also unstable, and working life is not long yet.

Show through medical research simultaneously, the human basic reason that produces disease be since various harmful germs 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 water supply line, carry the potable water process can produce a large amount of bacteriums.

The model utility content

In order to solve the problem of above-mentioned existence, the purpose of this utility model provides a kind of foamed heat insulating PP-R stable state and moulds the antibiotic composite pipe of aluminium, to overcome the shortcoming that existing common PP-R tubing in use need wrap up thermal insulating material again.

To achieve these goals, the utility model is by the following technical solutions:

A kind of foamed heat insulating PP-R stable state is moulded the antibiotic composite pipe of aluminium; it comprises antibiotic layer, a PP-R layer, first bonding layer, aluminium strip layer, second bonding layer, the 2nd PP-R layer, insulating foam layer and external protection from the inside to the outside successively, and foamed heat insulating PP-R stable state is moulded the antibiotic composite pipe of aluminium and adopted the one composite design.

Preferably, described antibiotic layer is that nanometer material is made.

Preferably, the tackiness agent of described first bonding layer and second bonding layer is hot melt adhesive.

Preferably, described first bonding layer is identical with the wall thickness of second bonding layer.

Preferably, described external protection is made for the PE material.

Preferably, the wall thickness of a described PP-R layer is greater than the wall thickness of the 2nd PP-R layer.

The utility model heat-shielding performance is good and thermal insulation property stable, it is relatively simple for structure, can produce in a large number, by a kind of antibacterial plastic concentrate being compounded on the inwall of PP-R stable state plastic-al pipe material, its cost increases and is little, but effectively improved the quality of product and enlarged its purposes scope, can make the producer obtain high economic benefit, can save economic spending for the user again, the goods of its standard, also install convenience is provided, thereby can accelerate the engineering construction progress, reduce labourer's working strength to pipeline.

1. antibiotic layers among the figure, 2. a PP-R layer, 3. first bonding layer, 4. aluminium strip layer, 5. second bonding layer, 6. the 2nd PP-R layer, 7. insulating foam layer, 8. external protection.

Embodiment

Below in conjunction with drawings and the specific embodiments the utility model will be further described explanation.

Embodiment as shown in Figure 1; a kind of foamed heat insulating PP-R stable state is moulded the antibiotic composite pipe of aluminium; it comprises antibiotic layer 1 from the inside to the outside successively; the one PP-R layer 2; first bonding layer 3; aluminium strip layer 4; second bonding layer 5; the 2nd PP-R layer 6; insulating foam layer 7 and external protection 8; foamed heat insulating PP-R stable state is moulded the antibiotic composite pipe of aluminium and is adopted the one composite design; wherein antibiotic layer 1 is positioned at the innermost layer that foamed heat insulating PP-R stable state is moulded the antibiotic composite pipe of aluminium; for nanometer material is made; because nanometer material has the physical property of many uniquenesses; high temperature resistant; crushing resistance is strong; can also suppress the growth of bacterium; so moulding the antibiotic composite pipe of aluminium, foamed heat insulating PP-R stable state can be widely used in aspects such as water supply line; the tackiness agent of first bonding layer 3 and second bonding layer 5 uses is hot melt adhesive; and as shown in Figure 2; first bonding layer 3 is identical with second bonding layer, 5 these two-layer wall thickness; foamed heat insulating PP-R stable state is moulded the external protection 8 of the antibiotic composite pipe of aluminium and is made for the PE material, and the wall thickness that foamed heat insulating PP-R stable state is moulded a PP-R layer 2 of the antibiotic composite pipe of aluminium is greater than the wall thickness of the 2nd PP-R layer 6.

The utility model foamed heat insulating PP-R stable state is moulded the antibiotic composite pipe making of aluminium and be may further comprise the steps:
