Abstract
The utility model provides a high-strength plastic pipe whose strength can be increased by means of stretching and orienting the high molecular of the polymer. The utility model is characterized in that the pipe wall of a high-strength composite plastic pipe is provided with at least a plastic layer which is radially stretched and oriented or a plastic layer whose radial strength is higher than axial strength and at least one plastic layer which is axially stretched and oriented or one plastic layer whose axial strength is higher than radial strength. Compared with the general plastic pipe and the general composite pipe which can be produced by the extruding method, the high-strength composite plastic pipe of the utility model has higher inner stress bearing ability and comprehensive performance.
Description
The utility model relates to a kind of highstrenghtpiston's composite pipe 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 quite general in engineering is used, in order to satisfy the needs of different engineerings and pressure, except adopting different raw material and different tube wall thicknesses adapting to, adopt the be composited various pipelines of new structure material of different classes of material in addition, mould pipelines such as compound, glass and resin compounded as steel.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 for a kind of application and needs that can better adapt to above-mentioned engineering being provided, the monoway stretch-oriented high-strength composite plastic pipe of very high interior bearing capacity and stretching resistance all being arranged at radial and axial both direction.
The purpose of this utility model is achieved like this:
Have in the tube wall of the utility model high-strength composite plastic pipe one deck at least through the radial drawing orientation or radial strength be higher than the plastic layer of axial strength and have at least one deck through the axial tension orientation or axial strength be higher than the plastic layer of radial strength.
At least the plastic layer of the unstretched orientation of one deck is arranged in the above-mentioned composite plastic tube wall.
The plastic layer of unstretched orientation is one deck in the above-mentioned composite plastic tube wall, is positioned at the skin of tube wall.
Compound or fusion is compound between each plastic layer in the above-mentioned composite plastic tube wall by adhesive layer, also can adopt other method compound.
Each plastic layer of above-mentioned composite plastic pipe adopts the variety classes high molecular polymer to make.
Above-mentioned composite plastic pipe can flatten into tubular band and one-tenth coil around, carry, easy to use.
The utility model is because each layer plastic layer all is monoway stretch-oriented, and each layer has the higher degree of orientation of tube wall than the directed composite plastic pipe of biaxial tension, and higher intensity is also just arranged.Particularly stretch orientation is being arranged also axially, axial strength is also than composite plastic pipe height, and radial strength and axial strength have just had higher combined strength bination because two layers are composited after monoway stretch-oriented separately in addition.Therefore this pipe has more performance and economical with materials and reduce engineering cost more than composite plastic pipe on interior bearing capacity and combination property.The tube wall of this pipe has at least the plastic layer of the unstretched orientation of one deck and monoway stretch-oriented plastic layer compound, makes the connection between the pipe more convenient reliable, easier electric heat welding.Monoway stretch-oriented separately plastic layer can be two-layer compound, it also can be MULTILAYER COMPOSITE, can be that heat fusing is compound, also available Bond is compound, which floor can be different types of polymer between, can be congener polymer also, can fill nanometer or micron order mineral filler in the polymer, the shape of plastic tube can be a straight tube shape, also can be flatten into the tubular band become to coil around.
In sum, the utility model composite plastic pipe all has plastic tube and composite pipe than general extrusion molding production that higher interior bearing capacity and stretching resistance and combination property are arranged radial and axial, saves material, and can adapt to application and needs on the engineering better.
