Abstract
The present invention relates to one kind of high-strength composite plastic pipes with foamed layer and with high strength obtained through stretch and orientation of polymer molecules. The composite plastic pipe has at least one foamed plastic layer and at least one stretched and oriented plastic layer via radial and axial stretch or one plastic layer with radial strength higher than axial strength. The composite plastic pipe of the present invention is material saving, higher in inner and outer bearing capacity, heat insulating performance and comprehensive performance.
Description
What the present invention relates to is a kind of high-strength composite plastic pipe that foaming layer is arranged of gaining in strength by the macromolecule stretch orientation of polymer.
The plastic tube of various materials, the composite pipe that comprises coextruding method production is used quite general in engineering, in order to satisfy the different needs of engineering and pressure rating, except adopting different materials and different tube wall thicknesses satisfy, also adopted in a large number with the be composited method of new structural material of different classes of material and come supply the market,, glass fibre compound and resin compound or the like such as steel and plastics.Utilize the macromolecule stretch orientation of polymer to gain in strength to be plastics particularly crystallization mould the technical feature that material has superiority most, can save great deal of raw materials, the most tangible for tubing is exactly to have saved thickness of pipe wall, but as everybody knows, along with the attenuate of tube wall, the thermal insulation property of plastic tube and outer bearing capacity reduce significantly.
In view of above reason, the objective of the invention is can economize in raw materials in order to provide a kind of, can keep or increase the high-strength composite plastic pipe that foaming layer is arranged of the stretch orientation of the thermal insulation property of tubing, inside and outside bearing capacity and rigidity again.
The object of the present invention is achieved like this:
Have in the tube wall of composite plastic pipe of the present invention one deck expandable plastic layer at least and at least one deck through the plastic layer of radial and axial biaxial tension orientation or be higher than the plastic layer of axial strength through radially monoway stretch-oriented plastic layer or radial strength.
The plastic layer that has the unstretched orientation of one deck in the above-mentioned tube wall at least.
Have the plastic layer of one deck in the above-mentioned tube wall at least through the axial tension orientation.
Plastic layer can be the variety classes high molecular polymer in the above-mentioned tube wall.
The plastic layer that has one deck mineral filler in the above-mentioned tube wall at least.
At least in one deck expandable plastic layer mineral filler is arranged in the above-mentioned tube wall.
There is one deck expandable plastic layer at least to be positioned at the skin of tube wall in the above-mentioned tube wall and the outermost surface of foaming layer has the close layer of matter.
Between each plastic layer adhesives layer is arranged in the above-mentioned tube wall.
Be that fusion connects between each plastic layer in the above-mentioned tube wall, also can adopt other method compound.
Above-mentioned composite plastic pipe can flatten into tubular band and one-tenth coil around, carry, easy to use.
Have in the composite plastic pipe of the present invention one deck expandable plastic layer at least and at least one deck through the plastic layer of radial and axial biaxial tension orientation or the plastic layer that is higher than latitudinal strength through the plastic layer or the radial strength of radially simple tension, so compare with the plastic tube or the composite pipe of general extrusion molding production, except that saving material, can also increase the thermal insulation property of plastic tube and inside and outside bearing capacity and rigidity and the combination property of Geng Gao.
