Abstract
The invention relates to a novel reinforced winding pipe. The pipe wall of the novel reinforced winding pipe is of a straight pipe structure. A vertical reinforcing rib is wound around the straight pipe. Polyethylene resin or polypropylene resin is used as the main raw material of the straight pipe. The vertical reinforcing rib is made of a reinforcing thermoplastic structure strip. By means of the novel reinforced winding pipe, the strength of a steel-strip winding pipe is reached, meanwhile, the stripping strength and the tensile strength of a seam are remarkably improved, and therefore the possibility of pipe layering is reduced. The reinforcing structure is made of plastic not prone to corrosion, so that the service life is greatly prolonged. Besides, the novel reinforced winding pipe is completely made of a thermoplastic material, thereby being capable of being directly broken for reuse.
Description
Technical field
The present invention relates to engineering plastics application, be specifically related to a kind of novel enhanced entwining tube.
Background technique
Steel band reinforced winding pipe is that employing high density polyethylene (HDPE) and steel band are raw material, by the Wrapping formed novel tube of hot extrusion.It is except having the features such as inner wall smooth, flow resistance be little, also there is excellent high rigidity, high strength and good toughness, and the feature such as impact resistance is strong, as a kind of novel plastic pipeline, steel band enhanced polyethylene wound drain pipe, with the high ring rigidity that it was had, is highly suitable for the drainage pipeline project fields such as rainwater, sewage and discharge of wastewater system.
But, because peeling strength bonding between plastics and steel band interface layer is not high, cause steel band and the easy delamination of plastics in product; Due to the susceptibility-to-corrosion of steel, make product not long working life simultaneously, have larger hidden danger.In addition, owing to having used steel as reinforcing material, tubing weight is increased, to construction, make troubles and be difficult for reclaiming, caused the raising of cost.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of novel enhanced entwining tube, and it can solve steel strip winding pipeline interface well in conjunction with not strong, the perishable and shortcomings such as trouble and more difficult reuse of constructing.
The present invention is achieved through the following technical solutions:
The tube wall of described a kind of novel enhanced entwining tube is straight tube structure, and described straight tube twines outward and is provided with upright stiffening rib; It is main raw material that described straight tube adopts polyethylene or acrylic resin, and described upright stiffening rib adopts and strengthens thermoplastic structure's band.
Further, the melt index of described polyethylene and acrylic resin is 0.1-3.0g/10min, and density is 0.94-1.0g/cm
3.
Further, described enhancing thermoplastic structure band employing glass fiber reinforced polypropylene or carbon fiber Reinforced Polypropylene or nylon material are main raw material.
Further, the melt index of described glass fiber reinforced polypropylene, carbon fiber Reinforced Polypropylene and nylon material is 0.5-3.0g/10min, and tensile strength is 50-100MPa, and flexural strength is 120-260MPa.
Use novel enhanced winding pipeline provided by the invention, when reaching steel strip winding pipe intensity, the tensile strength of peeling strength and seam obviously improves, thereby reduces pipe layered, strengthens structure and adopts uncorruptible plastics, greatly increases the service life.Meanwhile, use novel enhanced winding pipeline provided by the invention, all adopt thermoplastic material, can direct broken reuse.
Compared with prior art, the invention has the beneficial effects as follows: novel enhanced entwining tube provided by the invention, can solve steel strip winding pipeline interface in conjunction with not strong, perishable, product weight is heavy and be difficult for the shortcomings such as reuse, has reduced cost.
