Abstract
The invention discloses a steel-plastic composite pipe with ultra-high molecular weight. The pipe includes: a polyethylene layer with ultra-high molecular weight, an adhesive resin layer, a fibrous skeleton layer, an adhesive resin layer, a high density polyethylene layer, a steel-belt spiral winding protective layer and a modified polyethylene layer, which are arranged in order from inside to outside. The fibrous skeleton layer is a net-shaped skeleton structure formed by left and right spiral winding of high molecular carbon fiber filaments. According to the technical scheme of the invention, high molecular carbon fibers replace original coppered steel wire in the manufacturing of the skeleton layer, which reduces the weight of the composite pipe while the original performance is maintained. The armored steel belt spiral winding protective layer and a copper film layer on the inner wall of the steel belt spiral winding protective layer achieve an ultra-high protective stiffness, which can effectively prevent any kind of impact or damage. The modified polypropylene serves as the outermost layer of the composite pipe, which can effectively elevate ultra-wearing resistance of the composite pipe.
Description
Technical field
The present invention relates to a kind of tubing, particularly relate to a kind of steel-plastic composite pipe.
Background technique
Steel-plastic composite pipe is for reinforcement with the Wrapping formed mesh skeleton structure of high strength Coppered Steel Wire left-and-right spiral, high density polyethylene (HDPE) is matrix, utilize high performance high-density polyethylene modified adhering resin, shaping composite pipe is finally met on a production line by continuous gradation extrusion molding, there is the performance of excellent wear-resisting, withstand voltage, cracking resistance, be widely used in long apart from buried fluid-duct-system.Existing steel-plastic composite pipe can not bear larger external impact force at the construction field (site), easily cause the skeletal structure permanent damage of composite pipe inside, and then affect the working life of steel-plastic composite pipe, and the steel wire net skeleton that the skeletal structure of existing steel-plastic composite pipe adopts has the large feature of weight, need to be alleviated further when not reducing performance the weight of composite pipe.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide a kind of super high molecular weight steel-plastic composite pipe.
In order to solve the problems of the technologies described above; the present invention is achieved by the following technical solutions: a kind of super high molecular weight steel-plastic composite pipe; it comprises the ultra-high molecular weight polyethylene layer, bonding resin layer, fiber reinforcement layer, bonding resin layer, high-density polyethylene layer, ribbon spiral winding protective layer and the modification polypropylene layer that set gradually from inside to outside, and described fiber reinforcement layer is the Wrapping formed mesh skeleton structure of macromolecule carbon cellosilk left-and-right spiral.
As preferably, the filametntary diameter of described macromolecule carbon is 1 ~ 5mm.
As preferably, described ribbon spiral winding protective layer is armored ribbon spiral winding protective layer.
As preferably, the thickness of described armored ribbon spiral winding protective layer is 1 ~ 4mm.
As preferably, the steel strip surface of described armored ribbon spiral winding protective layer inwall side is coated with copper film layer.
As preferably, the thickness of described modification polypropylene layer is 0.1 ~ 6mm.
Compared with prior art, advantage of the present invention is: adopt macromolecule carbon fiber to substitute original Coppered Steel Wire to manufacture framework layer, the basis maintaining original performance reduces the weight of composite pipe; Adopt the copper film layer on armored ribbon spiral winding protective layer and inwall thereof to achieve superelevation protection rigidity, can effectively prevent all kinds of impact failures; Adopt modification polypropylene as the outermost surface of composite pipe, effectively can promote the super abrasive performance of composite pipe.
