Abstract
The invention relates to the technical field of plastic pipes, in particular to a PPR (polypropylene randon coplymer) compound pipe. The existing PPR pipes have a single-layer structure, and weak links in performances, can not meet various use needs, and have certain limitation. The PPR compound pipe is characterized by comprising an external PPR layer, a middle metal layer and an internal PE (Poly Ethylene) layer, hot melt glue is arranged between the adjacent layers, and the PPR compound pipe is formed by high-temperature and high-pressure extrusion compounding. A nanometer antibiosis layer is further coated on the inner wall of the PE layer. the PPR layer comprises the compositions in percentage by weight: 100kg of polypropylene, 3kg of color masterbatch and 1kg of compound assistants, the assistants include antioxidant, ultraviolet absorbers, light stabilizer and metal ion passivant at the weight proportion of 6:1:2:1. The PPR compound pipe combines the advantages of the PPR pipe and a metal compound pipe as a whole, and is light in weight, good in strength, and corrosion-resistant, has the advantages of being non-toxic, tasteless, high in surface cleanness, small in frictional coefficient, fast in flow speed, pressure-resistant, anti-aging, and good in ring stiffness, without scaling and the like, and is of a novel pipe which can be transported under both cold and hot conditions.
Description
Technical field
The present invention relates to plastic cement pipe technology field, especially a kind of PPR composite pipe.
Background technique
PPR pipe is to adopt atactic copolymerized polypropene to extrude the pipe fitting that forms, and is widely used in industry and builds interior life with the resident, comprises that health is quoted to feed water and hot water heating.And existing P PR pipe fitting is single layer structure, and there is weak link in performance, can not satisfy all kinds of user demands, has certain narrow limitation.
Summary of the invention
The present invention is directed to the defective that existing technology exists, a kind of PPR composite pipe is provided, intensity is high, asepsis environment-protecting, and using scope is extensive, satisfies people's user demand.
For this reason, the present invention takes following technological scheme: a kind of PPR composite pipe, it is characterized in that it outer is the PPR layer, the middle level is a metal layer, internal layer is the PE layer, said adjacent layer with layer between PUR is set, and extrude through HTHP and to be composited.
The inwall of said PE layer also is covered with the nano-antibacterial layer.
The weight proportion of each composition is in the said PPR layer: polypropylene 100kg, and look female 3kg, composite assistant 1kg, described auxiliary agent comprise that weight proportion is 6: 1: 2: 1 oxidation inhibitor, ultraviolet absorber, light stabilizer and metallic ion passivation agent.
Described polypropylene is the Yanshan Mountain 4220.
Described metal layer is zinc layer or aluminium lamination.
The outer surface carved with mark line of said PPR layer.
The advantage that the present invention combines PPR pipe and metal composite pipe material, in light weight, intensity good, corrosion-resistant.The nano-antibacterial layer that the inwall of composite pipe adopts has nontoxic, tasteless, advantages such as surface finishment is high, friction factor is little, non-scaling, flow velocity is fast, withstand voltage, anti-aging, ring stiffness is good, is the cold and hot novel tube that all can transmit; Also have killing and stop bacterium to grow, prevent the function of various growth of microorganism, make antibacterial action have endurance and Security, sterilization is efficient more than 90%, to be suitable for the purified water transporting system.Have the following advantages in addition:
1, heat preservation energy-saving, the pipe thermal conductivity is 0.21w/mk, is merely 1/200 of steel pipe,
2, better heat-resisting property is arranged, the dimension of PP-R composite pipe is blocked 131.5 ℃ of soft advantages, and Maximum operating temperature can reach 100 ℃, can satisfy the usage requirement of water heating system in the building water supply and drainage standard.
3, long service life, composite pipe can reach more than 60 years under 80 ℃ of operating temperatures, working pressure (P.N) 1.0mpa condition working life, and (20 ℃) can reach more than 130 years working life under the normal temperature.
4, connection easy for installation is reliable, has good welding performance, and pipe part can adopt hot melt to be connected with electric smelting, and the intensity of its attachment portion is greater than the intensity of tubing itself.
5, the recyclable utilization of material, composite pipe waste material are recycled after cleaning fragmentation in pipe part production, and the reclaimed materials consumption is no more than total amount 10%, do not influence the quality of product.
Embodiment
Through embodiment, do further bright specifically below to technological scheme of the present invention.
A kind of PPR composite pipe, its skin is the PPR layer, the middle level is a metal layer, internal layer is the PE layer, adjacent layer with layer between extrude through HTHP by PUR and to be composited, the inwall of PE layer also is covered with the nano-antibacterial layer.The weight proportion of each composition is in the PPR layer: polypropylene 100kg; Polypropylene is the Yanshan Mountain 4220; White look female 3kg, composite assistant 1kg, described auxiliary agent comprise that weight proportion is 6: 1: 2: 1 oxidation inhibitor, ultraviolet absorber, light stabilizer and metallic ion passivation agent; Metal layer is zinc layer or aluminium lamination, and the outer surface of tubing is the carved with mark line also.
The advantage that the present invention combines PPR pipe and metal composite pipe material, in light weight, intensity good, corrosion-resistant.The nano-antibacterial layer that the inwall of composite pipe adopts has nontoxic, tasteless, advantages such as surface finishment is high, friction factor is little, non-scaling, flow velocity is fast, withstand voltage, anti-aging, ring stiffness is good, is the cold and hot novel tube that all can transmit; Also have killing and stop bacterium to grow, prevent the function of various growth of microorganism, make antibacterial action have endurance and Security, sterilization is efficient more than 90%, to be suitable for the purified water transporting system.
What need particularly point out is; The mode of the foregoing description only limits to describe embodiment; But the present invention is confined to aforesaid way incessantly; And those skilled in the art can modify in not departing from the scope of the present invention in view of the above easily, and therefore scope of the present invention should comprise the disclosed principle and the maximum magnitude of new feature.
