Abstract
A combining double-wall composite pipe mainly aims at solving the technical problems of relatively complicated production process, higher production cost and the like of the existing large-diameter plastic pipe. The technical scheme of the combining double-wall composite pipe is as follows: an internal skeleton (1) is formed by the combination of two or more tile-shaped skeleton pieces; and one ormore layers of composite layers (2) are covered on the periphery of the internal skeleton (1); the cross section of the internal skeleton (1) takes the shape of a circle, a square, a semi-square semi-circle, or an chamfer square; and a reinforcing layer (4) can also be embedded in the tile-shaped skeleton pieces of the internal skeleton (1). By firstly combining the internal skeleton and then covering the composite layer, the production process is simpler. The combining double-wall composite pipe not only can produce large-diameter composite material pipes, but also can make use of waste plastic materials and the like for production, with relatively low production cost.
Description
Technical field
The present invention relates to a kind of composite pipe.
Background technique
At present, the production technology more complicated of existing major diameter plastic tube, and cost of production is higher.
Summary of the invention
But the purpose of this invention is to provide a kind of production major diameter and the relatively low combining double-wall composite pipe of cost of production.
The technical solution adopted for the present invention to solve the technical problems is: constitute inner frame 1 by watt shape matrix tablet more than 2 or 2, and be coated with composite bed 2 more than 1 layer or 1 layer in the periphery of inner frame 1.Described inner frame 1 section configuration comprise circle, square, en is semicircle or chamfering is square.Also can be embedded with reinforced layer 4 in watt shape matrix tablet of inner frame 1, described reinforced layer 4 can adopt by latticed or strip material to be made.The outer wall of described inner frame 1 also can connect firmly hollow or solid stiffening rib 3.The section configuration of described stiffening rib 3 comprises circle, circular arc, square or trapezoidal.The distribution mode of described stiffening rib 3 can adopt and comprise helical, circle shape, corrugated or latticed inner frame 1 outer wall that is looped around.Placement between watt shape matrix tablet of described inner frame 1 comprises hot melt, cold cut, snap button or the employing joint socket mode of adopting.Described inner frame 1 comprises with Placement between the clad 2 and adopts hot melt, cold cut or vacuum suction mode to be connected.Described composite bed 2 can adopt macromolecular material or modified alloy material to make, and is wrapped on the outer wall of inner frame 1.
The invention has the beneficial effects as follows: it coats composite bed again by making up inner frame earlier, makes production technology simpler.Both can produce large diameter composite material conduit, and can utilize materials such as waste or used plastics to produce, cost of production is relatively low.
