Abstract
The utility model provides a PP-R glass fiber reinforced composite pipeline which is high in impact resistance strength and good in heat stability, saves energy, and achieves environment friendliness. The PP-R glass fiber reinforced composite pipeline comprises an inner PP-R layer, a glass fiber reinforced layer and an outer PP-R layer. The inner PP-R layer is the inner layer of a pipe body, the glass fiber reinforced layer is arranged on the outer side of the inner PP-R layer, the outer PP-R layer is arranged on the outer side of the fiber glass reinforced layer, and all the functional layers are bonded together by gluing materials. Three extruders are utilized to conduct multilayer co-extrusion on the basis of an original PP-R pipe stock, the glass fiber reinforced layer is clamped and squeezed between the inner PP-R layer and the outer PP-R layer, then, all the functional layers of the composite pipeline are tightly combined into a whole, and therefore the PP-R glass fiber reinforced composite pipeline is high in strength and hardness, small in linear expansion coefficient and longitudinal shrinkage rate, and good in performance, saves energy, and achieves environment friendliness.
Description
Technical field
The utility model relates to the pipeline field, relates in particular to a kind of PP-R glass reinforced composite pipe road.
Background technique
PP-R pipe, i.e. polypropylene random copolymer pipe, be widely used in industry and house ornamentation engineering in water supply line, the interface of PP-R pipe adopts hot-melt technology, and pipe is fused together fully, has shock resistance and long-term creep behaviour preferably, installation suppress the test pass through after, will not leak again, reliability is high, but its heat-resisting quantity, resistance to pressure is all poor, and the long-term work temperature can not surpass 70 ℃, and its expansion coefficient is large, cause vertical relaxation shrinkage large, make the tubing life-span reduce.
Summary of the invention
According to above technical problem, the utility model provides the PP-R glass reinforced composite pipe road of a kind of excellent in cushion effect, good thermal stability, energy-conserving and environment-protective, comprise body, it is characterized in that: also comprise interior PP-R layer, glass enhancement layer, outer PP-R layer, described body is followed successively by interior PP-R layer, glass enhancement layer, outer PP-R layer from the inside to the outside, between each functional layer, by glueing material, is bonded together.
Described body is multi-layer co-extruded by three extruders, in the middle of interior PP-R layer and outer PP-R, makes each functional layer of composite pipe be closely integrated into an integral body pinching of glass enhancement layer.
The beneficial effects of the utility model are: the utility model adopts three extruders multi-layer co-extruded on the basis of original PP-R tubing, by the pinching of glass enhancement layer in the middle of inside and outside PP-R layer, make each functional layer of composite pipe be closely integrated into an integral body, make the intensity of tubing high, hardness is large, coefficient of linear expansion is little, vertically relaxation shrinkage is little, energy-saving and environmental protection, pipe performance is more superior.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Embodiment
Shown in Fig. 1, the utility model is further described:
As Fig. 1, interior PP-R layer-2, glass enhancement layer-3, outer PP-R layer-4;
Embodiment 1
The utility model is followed successively by interior PP-R layer 2, glass enhancement layer 3, outer PP-R layer 4 from the inside to the outside, adopt three extruders multi-layer co-extruded, centre by 3 pinchings of glass enhancement layer at interior PP-R layer 2 and outer PP-R layer 4, by glueing material, make each functional layer close adhesion of composite pipe become an integral body.
