The invention discloses a preparation method of a composite for an underground drainage corrugated pipe. The preparation method comprises the steps of adding high-density polyethylene, polylactic acid, an ethylene-propylene copolymer, polyurethane, zinc borate, di-n-octyl phthalate, epoxidized soybean oil and light calcium carbonate into an agitated vessel, and mixing the materials to obtain a mixture A; adding polyethylene resin, cationic polyacrylamide, 2-ethylhexanol, tricaprylyl citrate and chitosan into the agitated vessel, and mixing the materials to obtain a mixture B; and finally, mixing the mixture A with the mixture B, and carrying out melt extrusion on a mixture of the mixture A and the mixture B through a double-screw extruder, so as to obtain the composite. The composite is adopted to prepare the outer wall of a double-layer pipe, ring stiffness and ring flexibility of the prepared double-layer pipe are obviously improved, and performance requirements of large-diameter underground drainage blowdown pipes can be met.
Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of system of the effective composite of buried drain bellows
Preparation Method.
Background technology
It is widely used today as the high density polyethylene (HDPE) (HDPE) of drain pipe, soil pipe, buried cable pipe, agricultural drainage and irrigation pipe
Double-wall corrugated pipe is that a kind of outer wall is corrugated, inner wall smooth Tube, with same specification with intensity other class tubing phases
Than saving with materials, rigidly high, bendability is excellent, and the features such as high-impact, high resistance to compression, instead of biography in suitable scope
The steel pipe of system, cast iron pipe, pipe of cement, asbestos pipe and common plastics tube.But, the maximum of large-caliber double-wall bellow is perplexed at present
Problem is that ring stiffness is low.Now the maximum inner diameter of domestic double-wall corrugated pipe is 710mm, and relevant equipment manufacturer is just in Devoting Major Efforts To Developing mouth
The production line of footpath 1600mm, this performance to pipe material is put forward higher requirement.
Ring stiffness is one of most important performance indications of tubing, because tubing is not subject in the application of buried drain pipe
Intrinsic pressure or pressure is very low, and is solely subjected to external pressure and loads (including dynamic load and static load).If the ring stiffness of tubing is too little, tubing
By destructions such as the big deformation of generation or flexings, thus it cannot be guaranteed that the safe handling of tubing.How tubing is most effectively improved
Ring stiffness be tubing industry heat subject.
