Abstract
The utility model provides a polypropylene steady state compound pipe, which is a three-layer structure, the outer layer is an inorganic ultra-fine thin powder/ polypropylene compound material layer, the middle layer is a micro-fiber/ inorganic ultra-fine thin powder/ polypropylene compound material layer, and the inner layer is an inorganic ultra-fine thin powder/ polypropylene compound material layer. Coextrusion technology is used to directly form the pipe material. The compound pipe not only maintains good fusion joint, wholesomeness, and processability of the polypropylene pipe material, at the same time improves the mechanical strength and heat-resistance, prominently reduces the linear expansion coefficient of the pipe component, and improves the size stability of the pipe material. The utility model is mainly used as cold and hot water supply pipe.
Description
The utility model relates to a kind of plastic tube, particularly relates to a kind of polypropylene stable state composite pipe with three-decker.
Several polypropylene pipes that improved appear both at home and abroad successively in recent years, as glass fibre enhanced polypropylene plastic tube; The steel-plastic composite pipe of glass fiber reinforced polypropylene lining; The aluminium-plastic composite pipe of glass fiber reinforced polypropylene lining.The mechanical strength of these tubing, heat resistance, thermal expansion coefficient and dimensional stability all are improved, but can not carry out welding connects, need to adopt the connection of linking closely of mechanical type structure, sealing is relatively poor, pipe fitting cost height, and the metal of connection end is perishable, still can produce the secondary pollution of water quality, simultaneously, glass fibre enhanced polypropylene pipe toughness is lower, impact resistance a little less than.
The purpose of this utility model is to provide a kind of weldability, wholesomeness, processability good, and mechanical strength and heat resistance are higher, and linear expansion coeffcient is little, and dimensional stability is good, and the polypropylene stable state composite pipe by a straight forming of coextrusion technology.
The utility model polypropylene stable state composite pipe is a kind of composite pipe of three-decker, skin is inorganic ultramicro powder/PP composite material layer, the middle level is microfibril/inorganic ultramicro powder/PP composite material layer, and internal layer is inorganic ultramicro powder/PP composite material layer.Wherein, outer wall thickness is generally 25 ∽ 30% of thickness of pipe wall, and the middle level wall thickness is generally 30 ∽ 40% of thickness of pipe wall, and the internal layer wall thickness is generally 20 ∽ 30% of thickness of pipe wall.This pipe can once be directly formed to tubing by coextrusion technology, and is easy to process.Because outer and internal layer is PP composite material, in construction, can adopt fusion techniques to realize the connection of tubing, thereby improved sealing and reliability that tubing connects, it is good and take into account intensity, rigidity, toughness and the low thermal expansivity of balance that composite structure has been given tubing.
The advantage of the utility model polypropylene stable state composite pipe is that thermal expansion coefficient reduces about 40 ∽ 50%, and have good installation dimension stability, processability and a weldability, tubing, pipe fitting connect sealing reliably, the mechanical strength height, bearing capacity strengthens, and health is good, does not produce secondary pollution, mainly as hot water or cold water's supply pipe.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation
The utility model polypropylene stable state composite pipe is a three-decker, and skin is inorganic ultramicro powder/polypropylene material bed of material 1, and the middle level is microfibril/inorganic ultramicro powder/PP composite material layer 2, and internal layer is inorganic ultramicro powder/polypropylene material bed of material 1.
Claims (1)
1, a polypropylene stable state composite pipe, be multi-layer structure, it is characterized in that the outer inorganic ultramicro powder/PP composite material layer that is, the middle level is microfibril/inorganic ultramicro powder/PP composite material layer, and internal layer is inorganic ultramicro powder/PP composite material layer.
