Embodiment 1

[0033] refer to Figure 1 to Figure 4 , the present invention comprises a wear-resistant outer layer 1;

[0034] The inner wall of the wear-resistant outer layer 1 is provided with a pressure-resistant light-shielding layer 3, and a network cable pressure-resistant layer 2 is arranged between the wear-resistant outer layer 1 and the pressure-resistant light-shielding layer 3;

[0035] The inner wall of the pressure-resistant light-shielding layer 3 is provided with an antibacterial inner layer 4;

[0036] The wear-resistant outer layer 1, the network cable pressure-resistant layer 2, the pressure-resistant light-shielding layer 3 and the antibacterial inner layer 4 are co-extruded into a composite integrated structure through a co-extrusion machine.

[0037] Further, the thickness of the wear-resistant outer layer 1 is 0.8-1.1 mm, and the wear-resistant outer layer is made of PVC plastic.

[0038] Further, the mesh wire pressure-resistant layer 2 is made of synthetic polyest...

Embodiment 2

[0044] The antibacterial inner layer of the present invention is prepared according to the following process:

[0045] 1) Methyl methacrylate-butadiene-styrene copolymer, polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, trioctyl trimellitate, carbon black and glass fiber are mixed according to the ratio of 50:10:8 : Mix evenly with a mass ratio of 5:2:1:1, add to a banbury mixer, banbury time is 8min, banbury temperature is 80°C, and the main ingredient is obtained;

[0046] 2) Mix nano-titanium dioxide and nano-silver uniformly at a mass ratio of 1:1 to obtain a mixture, then add it to 1,3-butanediol of the same weight, stir at 500 rpm for 3 minutes, and then let stand for 30 minutes to obtain a composite nanomaterial;

[0047] 3) Put the main material and composite nanomaterials into the centrifuge in sequence according to the mass ratio of 10:1, and centrifuge at 1000rpm for 8 minutes. After mixing evenly, enter the twin-screw extruder to extrude into a molten stat...

Embodiment 3

[0049] Performance test of the antibacterial inner layer of the present invention.

[0050] 1. Set up a control group, control group 1: do not add nano-titanium dioxide, the rest is the same as the present invention; control group 2: do not add nano-silver, the rest is the same as the present invention; control group 3: do not add nano-titanium dioxide and nano-silver, the rest is the same as the present invention .

[0051]The control group and the test materials of the present invention are all placed in a petri dish, and the bacteria liquid or algae liquid is dropped on a sterile plate, cultivated in an incubator for 240min, then taken out, and counted under a microscope. The strength of the inhibitory ability was judged by the number of colonies. The lower the number of microorganisms, the stronger the inhibitory ability. Take Escherichia coli, Staphylococcus aureus and green algae as examples, see Table / 1 for details:

Abstract

The invention discloses a water delivery pipe with an antibacterial inner layer. The water delivery pipe with the antibacterial inner layer comprises a wear-resistant outer layer, an anti-compressionlight-shielding layer is arranged on the inner wall of the wear-resistant outer layer, and a net wire pressure-resistant layer is arranged between the wear-resistant outer layer and the compression-resistant light-shielding layer; the antibacterial inner layer is arranged on the inner wall of the anti-compression light-shielding layer, and the wear-resistant outer layer, the net wire pressure-resistant layer, the compression-resistant light-shielding layer and the antibacterial inner layer are co-extruded into a combined integrated structure through a co-extrusion machine. The water delivery pipe has relatively good bacteriostasis and algae inhibition performance, is further capable of resisting compression, anti-bending and resisting corrosion, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of flexible pipes, and in particular relates to a water delivery pipe with an antibacterial inner layer. Background technique [0002] In the prior art, PVC plastic hoses are currently widely used in the market as water delivery products. [0003] After use, because the remaining water in the water pipe is not completely drained, the inner wall of the water pipe will be polluted after a long time, and flakes of algae will fall off when the hose comes out of the water. If the end of the hose is connected with a nozzle, the nozzle will be blocked. This will not only bring inconvenience to use but also cause secondary pollution to water quality. Algae and chlorophyll are generally concentrated in the open waters of lakes and reservoirs, but after the completion of the water transfer operation, the remaining water in the pipes undergoes long-term photosynthetic reactions, and the problem of algae growth on the ...
