Embodiment 1

[0027] See figure 1 , figure 2 The present invention discloses a large-diameter cross-linked polypropylene winding structure wall pipe special for underground pipe gallery drainage and sewage (specifically a large-diameter flange connection type cross-linked polypropylene PP-X winding structure wall pipe special for underground pipe gallery drainage and sewage) The material of the pipe includes cross-linked polypropylene PP-X. The formula components of the pipeline material are: 100 parts by weight of polypropylene powder; 6-30 parts by weight of filler masterbatch for reinforcement; 2-45 parts by weight of polyethylene for toughening; 0.5-5 parts by weight of lubricant; 0.5-3 parts by weight Parts by weight of dicumyl peroxide DCP as initiator; 0.5-1.5 parts by weight of dibutyltin dilaurate DBTL as catalyst; 2-10 parts by weight of vinyltrimethoxysilane VTMOS as crosslinking agent; 2-10 parts by weight Parts by weight of unsaturated hydrocarbons as crosslinking aids; 0.5-10 ...

Embodiment 2

[0036] A special large-diameter cross-linked polypropylene wound structure wall pipeline for underground drainage and sewage discharge. The material of the pipeline includes cross-linked polypropylene PP-X, and the formula components of the pipeline material include:

[0037] 100 parts by weight of polypropylene powder; 6-30 parts by weight of filler masterbatch for reinforcement; 2-45 parts by weight of polyethylene for toughening; 0.5-5 parts by weight of lubricant; 0.5-3 parts by weight of initiator; 0.5-1.5 parts by weight Parts by weight of catalyst; 2-10 parts by weight of cross-linking agent; 2-10 parts by weight of cross-linking assistant; 0.5-10 parts by weight of masterbatch.

Embodiment 3

Abstract

The invention discloses a special large-diameter crosslinked polypropylene spirally enwound structure-wall pipeline for sewage drainage of a underground pipe gallery, specifically a special large-diameter flange-jointed crosslinked polypropylene PP-X spirally enwound structure-wall pipeline for sewage drainage of the underground pipe gallery. The pipeline is made of crosslinked polypropylene PP-X which comprises, by weight, 100 parts of polypropylene powder, 6-30 parts of reinforcing filling master batches, 2-45 parts of toughening polyethylene, 0.5-5 parts of lubricant, 0.5-3 parts of dicumyl peroxide (DCP) as an initiating agent, 0.5-1.5 parts of dibutyltin dilaurate (DBTL) as a catalyst, 2-10 parts of vinyl trimethoxy silane (VTMOS) as a crosslinking agent, 2-10 parts of unsaturated hydrocarbons as a crosslinking coagent and 0.5-10 parts of color master batches. The special large-diameter crosslinked polypropylene spirally enwound structure-wall pipeline has the advantages of capability of making exposed laying overhead, high bearing strength, high environmental creep stress resistance, aging resistance, long service life, high temperature resistance, abrasion resistance, fire resistance and the like, and is capable of fully meeting requirements of environmental technology on bringing large sewage drainage pipelines into a city pipe gallery.

Description

Technical field [0001] The invention belongs to the technical field of underground pipelines, and relates to a winding structure wall pipeline, in particular to a large-diameter cross-linked polypropylene winding structure wall pipeline special for underground pipe gallery drainage and sewage discharge. Background technique [0002] At present, the well-known drainage and sewage pipelines generally refer to buried HDPE double-wall corrugated pipes, PVC reinforced pipes, HDPE winding structural wall pipes, and glass fiber reinforced plastic sand pipes. The installation and construction methods are generally: slotting and burying the pipe, backfilling and restoring. The pipe connection method is generally socket type rubber ring seal, but also hot melt welding or heat shrink sleeve connection; the main technical index of the pipe is to withstand the external force pointing to the center of the circle, such as ring stiffness; ring flexibility. [0003] The large-diameter sewage pipe ...
