MUPO double-layer double-wave structure wall pipe

[0029] A kind of MUPO double-layer double-wave structure wall pipe, such as figure 1 As shown, the inner layer 1 and the outer layer 2 are formed by hot-melt compounding, and both the inner layer 1 and the outer layer 2 are made of nano-modified polyolefin materials;

[0030] The nano-modified polyolefin material comprises the following raw materials by weight: 60 parts of polyolefin, 5 parts of composite cold-resistant elastomer toughening agent, and 35 parts of inorganic nano-composite toughened reinforcing material;

[0031] The preparation method of nano-modified polyolefin material is as follows: polyolefin, composite cold-resistant elastomer toughening agent and inorganic nano-composite toughened reinforcing material are mixed, and then extruded and melted by a two-stage extrusion granulator to obtain nano-modified polyolefin. Permanent polyolefin material, barrel temperature: 160°C, 180°C, 180°C, 190°C, 190°C, die temperature: 190°C.

[0032] The polyolefin includes th...

[0043] A MUPO double-layer double-wave structure wall pipe. The difference between this embodiment and Embodiment 1 is that the nano-modified polyolefin material includes the following raw materials by weight: 70 parts of polyolefin, 10 parts of composite cold-resistant elastomer toughening agent parts, 20 parts of inorganic nanocomposite toughened reinforcing materials.

[0044] The composite cold-resistant elastomer toughening agent comprises the following ingredients by weight: 80 parts of ethylene octene copolymer, 20 parts of EVA, 6 parts of styrene, 3 parts of maleic anhydride, and 3 parts of dicumyl peroxide.

[0045] The inorganic nanocomposite toughening reinforcing material comprises the following ingredients by weight: 70 parts of nanoscale talcum powder, 30 parts of nanoscale active calcium carbonate, 3 parts of silane coupling agent, and 1.5 parts of aluminate coupling agent.

[0049] Such as Figure 1-2 As shown, a MUPO double-layer double-wave structure wall pipe includes an inner layer 1 and an outer layer 2; both the inner layer 1 and the outer layer 2 are of a rotary structure, and the outer layer 2 is coaxially arranged on the inner layer 1 through hot-melt composite On the outer peripheral surface, the outer layer 2 is wave-shaped, and the outer layer 2 has a plurality of crests 21 and a plurality of troughs a22. Structure, high structural strength.

[0050] Two double-layer double-wave structure wall tubes 100 pass through such as Figure 3-6 The connecting piece 200 shown is connected. The connecting piece 200 includes an outer ring part 3, an undercut assembly and a buckle 5; Hole 302, two groups of undercut components are arranged symmetrically along the central axis direction of the outer ring part 3, and the undercut components include a plurality of ring-shaped undercut parts 4 coaxially arranged side by side along the central axis di...
