Problems solved by technology

[0002] The current corrugated pipe only uses polyethylene or polypropylene as the raw material, and is a structural wall pipe made by one-piece extrusion process. It is widely used in municipal drainage, farmland water delivery and industrial sewage discharge, etc., and can replace traditional concrete pipes and cast iron pipes. tube, but the polyethylene or polypropylene material itself has poor performance in terms of material strength and toughness, and is prone to deformation
The existing technology usually only starts from the structure of the pipe, and there is no research on the material of the pipe body

Embodiment 1

[0042] Such as figure 1 As shown, one aspect of the present invention provides a MPPE modified polypropylene polyethylene composite reinforced double-walled reinforced corrugated pipe, comprising a pipe base 1, the outer side wall of the pipe base 1 is equidistantly provided with a number of outer walls along the circumferential direction The corrugated layer 11, the outer corrugated layer 11 is a hollow structure, the top of the outer corrugated layer 11 is provided with an M-shaped first reinforcing rib 12, and the outer corrugated layer 11 is arranged along the circumferential direction of the pipe substrate 1 A number of second reinforcement ribs 13 are provided, and a number of third reinforcement ribs 14 are arrayed along the axial direction on the outer side wall of the tube base 1.

[0043] In this embodiment, the outer corrugated layer and the second reinforcing ribs staggered along the circumferential direction of the pipe base enhance the overall rigidity and anti-extru...

Embodiment 2

[0045] As an improvement of embodiment 1, such as figure 2 As shown, the remaining features are the same as in embodiment 1, except that one end of the pipe base 1 is provided with a socket flaring 2. When the corrugated pipe is connected, the connection of the corrugated pipe is ensured by the socket hot melt The tightness.

Embodiment 3

[0047] As an improvement of embodiment 1, such as image 3 As shown, the remaining features are the same as Embodiment 1, except that the outer wall of the socket flaring 2 is equidistantly provided with several outer wave layers 11 along the circumferential direction, which further enhances the rigidity of the corrugated pipe connection.

Abstract

The invention provides an MPPE (modified polypropylene and polyethylene) composite enhanced double-wall reinforced corrugated pipe and a manufacturing method thereof. The MPPE (modified polypropyleneand polyethylene) composite enhanced double-wall reinforced corrugated pipe comprises a pipe substrate, wherein a plurality of outer corrugated layers are circumferentially arranged at the outer sidewall of the pipe substrate at equal intervals; each outer corrugated layer is of a hollow structure correspondingly; a M-shaped first reinforcing rib is arranged at the top of each corresponding outercorrugated layer; a plurality of second reinforcing ribs are arranged between the outer corrugated layers along the circumferential direction of the pipe substrate; and a plurality of third reinforcing ribs are axially arrayed on the outer side wall of the pipe substrate. The manufacturing method comprises the steps of 1, uniformly mixing and stirring high-density polyethylene particles and polypropylene particles, and carrying out melt extrusion; 2, drying and grinding the material obtained in the step 1 into powder, uniformly mixing the powder with inorganic material powder, and carrying out melt extrusion again; and 3, drying and grinding the material obtained in the step 2 into powder, and carrying out melt extrusion the third time according to the shape of a mold to obtain the pipe.The MPPE (modified polypropylene and polyethylene) composite enhanced double-wall reinforced corrugated pipe has excellent rigidity and extrusion resistance.

Description

Technical field [0001] The invention relates to the technical field of municipal water supply and drainage pipelines, in particular to an MPPE modified polypropylene polyethylene composite reinforced double-wall reinforced corrugated pipe and a preparation method. Background technique [0002] The current corrugated pipes only use polyethylene or polypropylene as the raw material, and adopt the integral molding extrusion process to make structural wall pipes. They are widely used in municipal drainage, farmland water delivery and industrial sewage, etc., and can replace traditional concrete pipes and cast iron. Pipes, but polyethylene or polypropylene materials themselves have poor performance in terms of material strength and toughness, and are prone to deformation. The existing technology usually only starts from the structure of the pipe, and there is no research on the material of the pipe body. Summary of the invention [0003] Based on this, it is necessary to propose a MPP...
