Description
Technical field
The utility model relates to a kind of plastic composite pipe, particularly a kind of high pressure resistant polynary PE plastic composite pipe.
Background technique
Supplying drainage is widely used in the plumbing such as highway, railway bed, subway engineering, Landfills, tunnel, green belt, sports ground field, and subirrigation and the drainage system of agricultural, gardening.Under the traditional metal supplying drainage was buried because of length, especially easily rust corrosion, even caused the serious problems such as perforation, obstruction.At present, the steel-plastic composite pipe development is very fast, and it is just constantly replacing the pipeline of various metal pipes and other traditional material in every field.Disclose a kind of steel as Chinese patent and moulded the production method of multi-element composite pipes (number of patent application 201110197543.3), this invention is at first with HDPE or PVC modifying plastics and be made into plastic board/belt; The hollow reinforced rib of making the dual-side indent and mutually overlapping; With the notch welding of continuous welding equipment with the interior recess in stiffening rib bottom; Stiffening rib after welding is synchronizeed with plastic board/belt be wound around the formation inner tube wall; Cover glue, roll extrusion on Wrapping formed tube wall; Covered fiber net or winding fiber band and roll extrusion on the tube wall after roll extrusion; Cover glue and roll extrusion on layer of fibers, form the pipe outer wall; The tubing fixed length cutting of the 7th step will be completed; The stiffening rib port sealing of tubing one end after will cutting, the cement slurry for preparing in advance toward the interior injection of the square stiffening rib of the tubing the other end with grouting equipment; The tenth step: the tubing of filled with water material-mud is stood to holding up, fixing, cement slurry is solidified, be formed into product tubing.The advantage of this programme is to resist interior pressure, critical external compressive resistance, prevents breaking and reducing the tubing coefficient of thermal expansion and contraction, prevents that simultaneously stiffening rib from getting rusty.This patent technique is made too loaded down with trivial details, needs to adopt with HDPE or PVC plastics, cement slurry compound, and this has increased production difficulty on the one hand, directly affect again on the other hand between pipeline compound firmly, even cause pipeline breaking.
Summary of the invention
The purpose of this utility model is that a kind of high pressure resistant polynary PE plastic composite pipe will be provided, and existing composite pipe shock resistance is poor to solve, compressive strength high-technology problem not.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of high pressure resistant polynary PE plastic composite pipe, described water pipe innermost layer is UHMWPE core pipe, described UHMWPE core pipe is wrapped with the first stainless steel stratum reticulare, the first stainless steel stratum reticulare is wrapped with the PE middle close binder, be enclosed with the second stainless steel stratum reticulare on described PE middle close binder outer wall, the second stainless steel stratum reticulare is wrapped with the HDPE weathering layer.
The utlity model has that high-performance, high applicability, adhesive strength are high, the nontoxic characteristics such as non-stimulated, corrosion-resistant.Its UHMWPE core pipe has good wear resistance, impact resistance, and under the condition of equal load, the wear resistance of this pipe is even also good than steel pipe, comes out at the top in all engineering plastics.Its first, second stainless steel stratum reticulare can further increase UHMWPE core pipe compressive strength, impels high strength UHMWPE core pipe to be difficult for breaking, and has simultaneously good shock resistance, only needs thinner tube wall just can meet the demands during application.The PE binder course adopts thermoplastic elastomer (TPE), has improved core pipe and outer field binding ability, and can reach 60 years its working life.
