Abstract
The utility model relates to a novel polypropylene double-wall corrugated pipe, which comprises a corrugated outer layer and a flat-wall inner layer, wherein the corrugated outer layer is made of a polypropylene resin material of which the elastic modulus is more than 1,700 MPa; and the flat-wall inner layer is made of a polypropylene resin material added with metal powder. The novel polypropylene double-wall corrugated pipe has the advantages that the outer pressure resistance of the pipe is improved; and the inner wall of the pipe contains metal materials, so that the pipe is convenient to control and maintain, and management for underground pipelines is facilitated.
Description
Technical field
The utility model relates to a kind of plastic tube, particularly a kind ofly buries the polypropylene bellows that ground draining blowdown is used.
Background technique
Use plastic tube as burying the ground draining, in order to guarantee its safe handling, it must have external weight bearing power such as the soil of opposing and vehicle and keep the indeformable ability of sectional shape; The Young's modulus of the acrylic resin that polypropylene double-walled bellows commonly used is used needs with bigger thickness below 1250MPa, and weight is heavier; Because tubing is embedded in underground; And material is nonmetallic material, therefore can't detect its pipeline trend and buried depth on ground, is unfavorable for the management of underground utility.
Summary of the invention
The purpose of the utility model is that a kind of novel polypropylene double-walled bellows that can solve existing background technique shortcoming will be provided.
The technological scheme of the utility model is: a kind of novel polypropylene double-walled bellows; Comprise undulations surrounding and planomural internal layer; Described undulations surrounding material is the acrylic resin of Young's modulus greater than 1700MPa, and described planomural internal layer material is the acrylic resin that is added with metallic dust.
The outstanding advantage that the utility model relates to is: improved the critical external compressive resistance ability of tubing, because inner tube wall contains metallic material, be convenient to the detection and the maintenance of pipeline simultaneously, helped the management of underground utility.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of novel polypropylene double-walled bellows comprises undulations surrounding and planomural internal layer, and described undulations surrounding material is the acrylic resin of Young's modulus greater than 1700MPa, and described planomural internal layer material is the acrylic resin that is added with metallic dust.Adopt double-layer coextrusion extruder and Mould Machining moulding during production.
Claims (1)
