Abstract
The utility model relates to a stretch oriented high-strength composite plastic pipe with a foam layer; the strength of the stretch oriented high-strength composite plastic pipe with the foam layer can be increased by stretching and orienting the high molecular of the polymer. The pipe wall of the composite plastic pipe is provided with at least a foamed plastic layer and at least an oriented plastic layer which is carried out the radial and axial stretching operation or an oriented plastic layer which is radially stretched or a plastic layer whose radial strength is higher than axial strength. Compared with the general plastic pipe and the general composite pipe which are produced by the extrusion process, the composite plastic pipe of the utility model not only can save the raw material, but also can have higher internal and external pressure bearing ability and higher heat-insulating property and combination property.
Description
The utility model relates to 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 purpose of this utility model 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 purpose of this utility model is achieved like this:
Have in the tube wall of the utility model composite plastic pipe 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.
The plastic layer that has one deck mineral filler in the above-mentioned tube wall at least has mineral filler in one deck expandable plastic layer in the tube wall at least.
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, can adopt fusion to connect in the tube wall between each plastic layer, also can adopt other method to connect.
Above-mentioned composite plastic pipe can flatten into tubular band and one-tenth coil around, carry, easy to use.
Plastic layer can be the variety classes high molecular polymer in the above-mentioned tube wall.
Have in the utility model composite plastic pipe 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.
