Description
Technical field
The invention belongs to plastic tube technical field, refer in particular to a kind of three-layer co-extruded sandwich honeycomb duct and production technology thereof.
Background technology
At present, plastic pipe market used is varied, such as: a class is plastic double-wall corrugated pipe: feature: interior
Wall is smooth, and outer wall is concavo-convex, and outer wall is by servo-actuated concavo-convex continuously shaped to compound module, axially soft flexible, connects and seals easily, footpath
Enough to ring stiffness, but axial rigidity is relatively low, produces equipment cost high；Two classes are the axially hollow wall tube material of plastic double-layer: special
Point: inside and outside wall is smooth, axially hollow through full pipe, axial rigidity is enough, connects and seals easily, but radially ring stiffness is relatively low,
Resisting environmental stress and cracking ability is low；Three classes are plastic winding reinforcement tubing: feature: inwall is smooth, and outer wall has spiral convex rib, body
By one fixed width extrusion band continuous winding welding or bonding forming, axially soft flexible, connect and seal easily, radially ring stiffness
Enough, but axial rigidity is relatively low, produces equipment cost high；Also have plastic winding structural wall tube, steel band reinforced plastic spiral
Corrugated pipe etc.；There is relatively low or that radially ring stiffness the is relatively low deficiency of axial rigidity in these tubing, is exactly also outer wall light not
The defects such as sliding, production equipment cost is high.
Summary of the invention
It is an object of the invention to provide the good three-layer co-extruded sandwich honeycomb duct of a kind of integral structure, overall performance and life thereof
Production. art.
The object of the present invention is achieved like this:
Three-layer co-extruded sandwich honeycomb duct, including the sandwich of layers between inner tube, outer tube and inner tube and outer tube, described
Inner tube, sandwich of layers, outer tube be with the integral structure of extrusion molding of plastic material, described inner tube and outer layer
The tube wall of pipe is solid construction, and described sandwich of layers is honeycomb layer.
The axis of the honeycomb of above-mentioned honeycomb layer is perpendicular or parallel to inner tube or/and the axis of outer tube.
Above-mentioned inner tube, sandwich of layers, the ratio of thickness of outer tube be: D1:D2:D3=1:(5-8): (2-4).
The production technology of three-layer co-extruded sandwich honeycomb duct, by three Fluid Channel for Plastic Extrusion Die of an injection molding extruder by happy and harmonious shape
The disposable extrusion molding of plastics of state goes out to have the sandwich tube of inner tube, sandwich of layers, outer tube, and sandwich tube is during extrusion
Being fused into one formula structure by temperature during plastic extrusion and viscosity, the inner tube of extrusion molding and the tube wall of outer tube are reality
Core structure, sandwich of layers are honeycomb layer.
The axis of the honeycomb of above-mentioned honeycomb layer is perpendicular or parallel to inner tube or/and the axis of outer tube.
Above-mentioned inner tube, sandwich of layers, outer tube material is identical, extrusion temperature and extrusion pressure identical.
The present invention highlights and useful having the technical effect that compared to existing technology
1, the axis of the honeycomb of the honeycomb layer of the present invention is perpendicular to inner tube or/and during the axis of outer tube, product
Radial direction ring stiffness high, axial rigidity also can reach requirement, but also it is light to have overall weight, and surfaces externally and internally is smooth, bulking property
The advantage that energy is high.
2, the axis of the honeycomb of the honeycomb layer of the present invention is parallel to inner tube or/and during the axis of outer tube, product
Axial rigidity high, radially ring stiffness also can reach requirement, but also it is light to have overall weight, and surfaces externally and internally is smooth, bulking property
The advantage that energy is high.
3, the sandwich of layers of the present invention uses honeycomb layer, the surfaces externally and internally of honeycomb layer and the outer surface of inner tube,
The inner surface of outer tube is all fused into one formula structure by temperature during injection extrusion and viscosity, it is not necessary to bonding or welding, whole
Body weight is light, and surfaces externally and internally is smooth, and overall performance is high, it is adaptable to pipeline that performance requirement is higher or conduit.
