Abstract
The nanometer modified great caliber double wall polyethylene corrugated pipe is produced with HDPE material with added mother material and has nominal diameter over 400 mm. Into 100 weight portions of HDPE material, are added micron level CaCO3 mother material 15-25 weight portions and nanometer level CaCO3 mother material 8-16 weight portions. The mother material is prepared with micron level CaCO3 or nanometer level CaCO3 as well as certain amount of HDPE resin, dispersant and coupler, and through mixing, smelting and extruding. The corrugated pipe has the technological specification meeting the requirement of GB/T 19472.1-2004, and has high rigidity and impact strength.
Description
One, technical field
The present invention relates to a kind of plastics of modification, the polyethylene molding product that particularly a kind of usefulness is nano-material modified exactly are a kind of nano modified poly ethylene large caliber double wall corrugated pipes.
Two, background technology
Polyethylene (PE) is a kind of thermoplastics, and excellent chemical resistance and electrical insulation capability are arranged.Be widely used in and prepared container or lining, chemical mediator pipeline, gas line and water pipe and electrical component and the wire cable insulating layer or the like that holds chemical.PE is applicable to multiple moulding process, as coating, thermoforming, extrusion moulding, injection moulding or blow molding and rotation-formed etc.Can select corresponding moulding process according to the needs of purposes.
The PE tubing system of burying ground is comprised that tubing, pipe fitting etc. should meet the technical indicator of standard GB/T 19472.1-2004 regulation.To the tubing of nominal diameter greater than 500mm, T-Ring rigidity magnitude classification has six grades in this standard, and meaning nominal ring stiffness grade is called for short the ring stiffness grade.
As everyone knows, the starting raw material of PE is an oil, with the PE resin is being raw material when processing various goods, and the consumption that if can save PE just equals to have saved the energy, also can reduce cost concerning enterprise simultaneously with the reply intense market competition.CN1542040A discloses a kind of matrix material of the PE of preparation tubing, is to dose mineral filler and properties-correcting agent in high density polyethylene(HDPE) (HDPE), and mineral filler comprises glass fibre, mica, ultra-fine CaCO
3And cenosphere, properties-correcting agent comprises titanic acid ester, aluminic acid ester and silane coupling agent.
The appearance of nano material and develop into macromolecular material particularly the modification of plastics a new approach is provided.At present both at home and abroad the research Showed Very Brisk, particularly nano material of this respect to the study on the modification of polyvinyl chloride (PVC) early, report is also more.
Three, summary of the invention
The alleged poly ethylene large caliber double wall corrugated pipe (following abbreviation corrugated tube) of the present invention is meant the corrugated tube of nominal diameter greater than 400mm.With high density polyethylene(HDPE) (HDPE) is raw material.
The present invention adds mineral filler to constitute matrix material to replace part PE resin in the HDPE resin, this compound material is processed into corrugated tube with extruding-out process.Technical problem to be solved is that this corrugated tube should meet every index that GB/T19472.1-2004 stipulates on the one hand, on the other hand corrugated tube is carried out modification, improve the ring stiffness grade and strengthen toughness, bury the safe in utilization of ground operating mode and increase the service life guaranteeing, be significantly reduced to this simultaneously.
Described mineral filler is nano-calcium carbonate (CaCO
3) and micro-calcium carbonate (CaCO
3).For making filler and HDPE resin particle blending dispersion even; improve mineral filler and organic PE interphase interface consistency simultaneously; filler will be aided with auxiliary agent and be processed into granular masterbatch, masterbatch and PE mixed with resin are uniformly dispersed and constitute compound material, are extruded into and mould machining bellows.
Each component of this corrugated tube has following parts by weight:
