As shown in fig. 1 to 2, a wound structured wall pipe according to an embodiment of the present invention includes a pipe body 1 and at least one layer of ribbed pipe 2 wound outside the pipe body 1, where the pipe body 1 includes:

the outer wall of the blank tube 11 is provided with a tube material layer 12;

the sheet material layer 13 is arranged on one side of the tube material layer 12 far away from the blank tube 11;

the rib pipes 2 are wound on the side, far away from the blank pipe 11, of the plate material layer 13, and the pipe material layer 12 is made of rigid polyvinyl chloride.

It can be understood that, at present, because the preparation technology of the PE (Polyethylene) winding structure wall pipe is simple, and compared with the double-wall corrugated pipe, a buried drain pipe with a larger caliber (the caliber can reach DN300-DN 4000) can be manufactured, a huge market is popular with users, but because the modulus of the PE pipe is too low, only about 700MPa can be reached, the requirement that the ring stiffness of the large-caliber pipe needs to reach SN8 level is difficult to meet, and thus the application of the PE winding structure wall pipe is greatly limited. Although the modulus of a PP (Polypropylene) pipe is high and can reach 1400MPa, the processing temperature of PP is too high and generally exceeds 210 ℃, so that the inertia moment and the ring stiffness of the PP billet pipe are reduced due to the deformation of the PP billet pipe, and therefore, the application of the winding structure wall pipe is greatly influenced.

It should be noted that, the ribbed tube 2 may be provided with at least one layer according to the rigidity requirement of the winding structure wall tube, and obviously, the number of layers of the ribbed tube 2 may be increased according to the increase of the rigidity requirement of the winding structure wall tube according to the ribbed tube 2.

In an embodiment, the material of the embryonic tube 11 is block copolymer polypropylene, and the diameter of the embryonic tube 11 is 25mm to 180mm, it can be understood that the block copolymer polypropylene has a better high temperature resistance, so that the influence of deformation of the embryonic tube 11 under a higher temperature condition on the ring stiffness and the shape of the winding structure wall tube can be avoided.

In one embodiment, the tube material layer 12 is manufactured by an extensional rheological extrusion method; it can be understood that although PVC can greatly improve the ring stiffness and save the cost, PVC as a heat-sensitive material is not resistant to high temperature in the extrusion process, a common twin-screw extruder pushes and plasticizes the PVC mixing material by shearing and friction, the PVC material is easily decomposed due to high temperature and long stroke of the screw in the extrusion process, and the mechanical properties and the aging resistance of the winding structure wall pipe are greatly reduced after decomposition, in this embodiment, the pipe material layer 12 is manufactured by adopting a extensional rheology extrusion method, that is, the pipe material layer 12 is manufactured by adopting an extensional rheology extruder, compared with the shear rheology extrusion molding by using a shear rheology extruder, the method adopting an extensional rheology extrusion method has a better conveying plasticization advantage, the screw has a shorter length and a lower heating temperature, thereby reducing the conveying stroke and the plasticizing temperature, further, the thermal decomposition of the pipe material layer 12 made of hard polyvinyl chloride is avoided, the usage amount of a heat stabilizer is reduced, the product quality is improved, and meanwhile, the energy consumption is saved and the cost is reduced.

It should be noted that, the extensional rheology extruder for realizing the extensional rheology plasticizing transportation method may be composed of a blade plasticizing transportation unit, and a group of spaces with determined geometric shapes is composed of a rotor, a stator, a plurality of blades and a baffle plate, because the inner cavities of the rotor and the stator are eccentric, the volumes of the rotor and the stator can be changed from small to large and then from large to small periodically, the material is taken in when the volume is changed from small to large, the material is ground and compacted under the main action of tension and compression stress when the volume is changed from large to small, and simultaneously the material is melted, plasticized and discharged under the action of mechanical heat dissipation and external heating of the stator, and the material plasticizing transportation dominated by the tension deformation is completed to extrude the pipe material layer 12.

In one embodiment, the plate material layers 13 are spirally wound around the tube material layer 12, and two adjacent turns of the plate material layers 13 are overlapped at the side edges and overlapped with each other through an adhesive 14 (not shown in the figure); the tube bed 12 and the plate bed 13 are connected by an adhesive 14.

It can be understood that, because the processing rheological property and the melt adhesion of PVC are not as good as those of PE and PP, in the process of manufacturing the winding structure wall pipe, the overlapping portion of the two adjacent turns of the plate material layer 13 may have a phenomenon of loose overlapping, and similarly, the overlapping of the pipe material layer 12 and the plate material layer 13 may also have a phenomenon of loose overlapping, which may further cause water leakage of the winding structure wall pipe or detachment of the rib pipe 2, and obviously, the adhesive 14 is used to tightly bond the sides of the plate material layers 13 of the turns and the pipe material layer 12 and the plate material layer 13, thereby preventing the winding structure wall pipe from leaking water or detachment of the rib pipe 2 due to winding of the pipe material layer 12 and the loose connection of the pipe material layer 12 and the plate material layer 13.

s30: at least one layer of ribbed tubes 2 is wound on the side of the plate material layer 13 far away from the tube material layer 12.

It is understood that in step S10, the screw configuration of the twin screws in the extensional rheology twin screw extruder may be a combination of eccentric discs, kneading discs and screw elements. Wherein the eccentric discs and the kneading discs and the screw elements are concentrically arranged or eccentrically arranged, the kneading discs can be two-head or three-head, and can be the same thickness or different thicknesses, as shown in fig. 4, the extensional rheology twin-screw extruder comprises an extensional rheology twin-screw extruder main body 31, a main runner 32 connected to the extensional rheology twin-screw extruder main body 31, and a first pipe orifice die 33 and a second pipe orifice die 34 respectively connected to the main runner 32, in step S10, the extensional rheology twin-screw extruder is used for conveying and plasticizing the rigid polyvinyl chloride material, a sheet material layer 13 and a pipe material layer 12 coated on a billet pipe 11 are respectively extruded, the billet pipe 11 is made of block copolymer polypropylene, wherein the effective length of the twin-screw is 400mm to 700mm and the diameter is 35mm to 45mm, in this embodiment, the length of the twin-screw is 400mm and the diameter is 40mm, the rotating speed of the twin screw is controlled at 45 r/min.

In step S20, by providing a gluing device 35 at the first and second dies 33 and 34, an adhesive 14 is applied on the surface of the tube material layer 12 and the board material layer 13, and then the board material layer 13 is wound around and coated on the surface of the tube material layer 12 by a rotary die 36, the tube material layer 12 and the board material layer 13 are adhered by the adhesive 14, and finally in step S30: at least one layer of ribbed tubes 2 is wound on the side of the plate material layer 13 far away from the tube material layer 12.

In one embodiment, the step of respectively extruding the board layer 13 and the tube layer 12 coated on the blank tube 11 by using an extensional rheology twin-screw extruder to transport and plasticize the rigid polyvinyl chloride material comprises:

adding a rigid polyvinyl chloride material into a hopper 311 of the extensional rheology twin-screw extruder;

extruding a sheet material layer 13 from a first tube opening die 33 and a tube material layer 12 from a second tube opening die 34 of the extensional rheology twin-screw extruder respectively, wherein a blank tube 11 is arranged at the center of the second tube opening die 34, so that the blank tube 11 is coated by the tube material layer 12 extruded from the second tube opening die 34;

wherein the extrusion temperature of the extensional rheology twin-screw extruder is less than 160 ℃, in an embodiment, the extensional rheology twin-screw extruder body 31 sequentially comprises, from the direction close to the hopper 311 to the direction far away from the hopper 311: the method comprises the following steps of extruding a first zone, extruding a second zone, extruding a third zone, extruding a fourth zone and extruding a fifth zone, wherein in the process of conveying and plasticizing a hard polyvinyl chloride material by using a stretching rheological double-screw extruder, respectively extruding a plate material layer 13 and a pipe material layer 12 coated on a blank pipe 11, the temperature of the first zone is 110 ℃, the temperature of the second zone is 120 ℃, the temperature of the third zone is 130 ℃, and the temperatures of the fourth zone and the fifth zone are 155 ℃; obviously, the billet tube 11 made of the block copolymerization polypropylene material can keep basically not deformed below 190 ℃, and the extrusion temperature of the PVC material is not more than 160 ℃, so that the billet tube 11 made of the block copolymerization polypropylene material is prevented from being scalded and deformed at an excessively high temperature, the appearance of the winding structure wall tube is full, and the high profile and the moment of inertia are ensured, so that the ring stiffness of the winding structure wall tube is further improved.
