Description
Technical field
The present invention relates to water supply tubing, particularly resident living water is for application tubing.
Background technique
Resident living water supply is at present used tubing to mainly contain four kinds.The first is galvanized iron conduit, be a kind of use electroplating chemical method at the plated surface last layer zinc of iron to reach antirust object metal tube, this pipe intensity is very high, not fragile; But it uses for a long time, pipe is inner can, because the existence of ponding and oxygen is got rusty, be unfavorable for water cleaning.The second is Stainless Steel Tube, is the tubing that adopts stainless steel material processing, and intensity is very high, can not get rusty, but price is very expensive, cost is high.The third is aluminium-plastic composite pipe, and it is a kind of multi-layer structure tubing, inside and outside two-layer be plastic layer, centre is metallic aluminium alloy-layer, between metal layer and plastic layer, has hotmelt that they are combined with each other.This tubing intensity is high, flexible; But after the use long period, metal and plastics meeting layering, decline tubing intensity, thereby easily damaged; Special when it uses as hot-water line, stratification is very serious.The 4th kind is PP-R(atactic copolymerized polypropene) pipe, this tubing is the acrylic resin plastic extruding forming tubing that uses a kind of random copolymerization, adopts hot melt to connect, and can be used for hot water or cold water's supply.Yet PP-R pipe can not be crooked, several meters one, during installation, need connect with more pipe fitting; And this kind of tubing is arranged on when outdoor, easily aging, working life is short.
Summary of the invention
The present invention be intended to provide a kind of non-corrosive, high temperature resistant, can be used for outdoor mounted, be difficult for aging, and lower-cost pipe material for water supply.
A kind of pipe material for water supply of the present invention, comprises inside and outside two-layerly, and internal layer is for adopting crosslinked polyethylene (PE-Xc) pipe of crosslinking with radiation explained hereafter, and skin be polyolefin pipe, and two-layer pipe adopts the mode that heats coating to be bonded together; In described outer field polyolefin pipe, added antioxidant, light stabilizer and had the color masterbatch of certain light shield effect and anti-aging effect, its preparation method is as follows:
A, at 180 ℃～230 ℃ temperature, be extruded into tubulose after polyethylene 99.4～99.7%wt and antioxidant 0.3～0.6%wt are mixed, under electron rays irradiation dose 80～120KGy, obtain internal layer crosslinked polyethylene pipe;
B, by polyolefin 96.5～98.2%wt, aluminium powder 0～2.5%wt, carbon black 0～2.3%wt, irgasfos 168 0.08～0.2%wt, antioxidant AT1010 0.03～0.15%wt, light stabilizer 0.2～0.5%wt are evenly mixed to get cladding material;
C, internal layer crosslinked polyethylene pipe is heated to 50～80 ℃ from mouth mould, passes, the cladding material of step B gained is extruded from mouth mould with molten form at 180 ℃～230 ℃, be bonded together with internal layer crosslinked polyethylene pipe; And make by water cooling.
A preparation method for pipe material for water supply, comprises the steps:
A, at 180 ℃～230 ℃ temperature, be extruded into tubulose after polyethylene 99.4～99.7%wt and antioxidant 0.3～0.6%wt are mixed, under electron rays irradiation dose 80～120KGy, obtain internal layer crosslinked polyethylene pipe;
B, by polyolefin 96.5～98.2%wt, aluminium powder 0～2.5%wt, carbon black 0～2.3%wt, irgasfos 168 0.08～0.2%wt, antioxidant AT1010 0.03～0.15%wt, light stabilizer 0.2～0.5%wt are evenly mixed to get cladding material;
C, internal layer crosslinked polyethylene pipe is heated to 50～80 ℃ from mouth mould, passes, the cladding material of step B gained is extruded from mouth mould with molten form at 180 ℃～230 ℃, be bonded together with internal layer crosslinked polyethylene pipe; And make by water cooling.
Pipe material for water supply of the present invention, internal layer is crosslinked polyethylene (PE-Xc) pipe of crosslinking with radiation explained hereafter, outer is the polyolefin pipe that has added antioxidant, light stabilizer, had the color masterbatch of light shield effect and anti-aging effect, its inside and outside two-layer macromolecular material that is, can not get rusty; And internal and external layer tubing is in the situation that long-term temperature alternately changes, can layering yet, be applicable to supply the pipeline of hot and cold water simultaneously.Described pipe material for water supply, the crosslinked polyethylene of internal layer makes pipe material for water supply have higher intensity; And as the outer field polyolefin pipe that has added anti-oxidant, light stabilizer and color masterbatch, make pipe material for water supply there is good aging quality resistance.In outer tubing, added antioxidant, it can suppress or delay the aerial slow thermal-oxidative degradation reaction of tubing, keeps the premium properties of tubing, increases the service life.The light stabilizer adding in outer tubing can shield or suppress again tubing and under daylight or hyperfluorescenceZeng Yongminggaoyingguang, absorb ultraviolet ray and the self-oxidation reaction of initiation, can keep tubing outward appearance and physical and mechanical properties, make tubing can there is comparatively good antibacterial anti ageing property, for outdoor mounted, the same life-span is long.Described pipe material for water supply is tested through accelerated ageing, and described pipe material for water supply still can pass through the pressure test of GB/T 18992-2003 in accelerated aging test after 1000 hours.The actual conditions of accelerated aging test is: adopt UVB-313 vitalight lamp to irradiate, radiant flux density 0.48W/m
2; Temperature 60 C; 4 hours condensation cycle of illumination in 4 hours.
