Description
Technical field
The present invention relates to a kind of resistance oxygen tubing and preparation method thereof, be specifically related to a kind of oxygen-resistance type PE-Xb tubing and preparation method thereof.
Background technique
Eighties of last century the eighties, in hot water cyclesystem, plastic pipe mostly is monolayer plastic pipe, and the metal parts in equipment gets rusty easily, and causes device damage serious.Reason is that after tubing heating, oxygen molecule is easily deep into through plastic layer in the water in pipe, causes the fast erosion of metal parts in equipment, and thus various resistance oxygen tubing arises at the historic moment.
At present conventional resistance oxygen tubing is primarily of composite pipe, resistance oxygen PE-X, resistance oxygen PE-RT, and wherein PE-X is widely used with advantages such as its good mechanical properties, high temperature resistant and cryogenic property are good.But, this kind of resistance oxygen tubing generally adopts the method for medium density polyethylene or high density polyethylene (HDPE) and crosslinked with silicane or peroxide crosslinking, mostly there is crosslinking agent to be not easily uniformly dispersed, the more difficult control one of the degree of cross linking is made peace needs timing cleaning screw rod to prevent the difficult points such as gel particle, and the quality control difficulty of product is large.In addition, PE-X skin scribbles oxidation prevention layer EVOH by glue, EVOH has fabulous barrier and fabulous processability to gas, the transparency, glossiness, mechanical strength, stretchability, wear resistance, winter hardiness and surface strength are all very excellent in addition, but oxidation prevention layer EVOH and inner plastic PE-Xb can not in conjunction with very well, outer oxidation prevention layer skewness, tubing resistance oxygen rate is unstable.
Summary of the invention
The present invention proposes a kind of oxygen-resistance type PE-Xb tubing and preparation method thereof, for solving the problem in background technique.
Technological scheme of the present invention is achieved in that
A kind of oxygen-resistance type PE-Xb tubing, comprise internal layer substrate layer and outer oxidation prevention layer, internal layer substrate layer is integrated by hot melt adhesive and outer oxidation prevention layer co-extrusion;
Substrate layer is PE-Xb, oxidation prevention layer is evoh layer, adulterate in hot melt adhesive coloured mother, in oxygen-resistance type PE-Xb tubing, the percetage by weight of each component is respectively: PE-Xb 94 ~ 99%, hot melt adhesive 5 ~ 30 ‰, EVOH3.5 ~ 30 ‰, look mother 0.15 ~ 5%, PE-Xb by percetage by weight be 5% silane and percetage by weight be 95% polyethylene be prepared from.
The oxygen-resistance type PE-Xb tubing that the present invention proposes is by arranging oxidation prevention layer EVOH at PE-Xb skin; can effectively prevent oxygen from infiltrating pipe-line system; metal parts in protective system is not by fast erosion, and the bacterium in killer tube and algae bio growth, extend the working life of tubing.
Preferably, the thickness 0.01 ~ 0.05mm of evoh layer.
Preferably, in oxygen-resistance type PE-Xb tubing, the percetage by weight of each component is respectively: PE-Xb94.7 ~ 98.85%, hot melt adhesive 5.78 ~ 26.37 ‰, EVOH 5.8 ~ 26.5 ‰, look mother 1 ~ 2%.
The invention allows for a kind of method preparing oxygen-resistance type PE-Xb tubing, by all raw materials first by suspension magnetic frame, remove the impurity such as the iron filings mixed in raw material, operate in accordance with the following steps afterwards:
The first step, by the melting of thermosol high-temperature heating;
Second step, substrate layer PE-Xb coats hot melt adhesive, forms the bonding layer as mesosphere;
3rd step, adds look mother in proportion in hot melt adhesive, and it is one deck that high temperature mixes rear hot melt adhesive by internal layer substrate layer and outer oxidation prevention layer co-extrusion, oxidation prevention layer thickness 0.01 ~ 0.05mm.
Preferably, substrate layer PE-Xb is added in proportion in substrate layer extruder by material polyethylene and silane and extrudes, and extruder temperature setting stepwise is at 150 ~ 195 DEG C.
Existing PE-X hinders the method that oxygen tubing generally adopts medium density polyethylene or high density polyethylene (HDPE) and crosslinked with silicane or peroxide crosslinking, mostly there is crosslinking agent to be not easily uniformly dispersed, the more difficult control one of the degree of cross linking is made peace needs timing cleaning screw rod to prevent the difficult points such as gel particle, and the quality control difficulty of product is large.The present invention, by setting suitable crosslinking temperature 150 ~ 195 DEG C and crosslinked ratio (silane percetage by weight is 5%, and polyethylene weight percentage is 95%), obtains excellent PE-Xb material.
Preferably, hot melt adhesive puts into high-temperature heating melting in tackiness agent extruder, and tackiness agent extruder temperature setting stepwise is at 200 ~ 210 DEG C.
Often there is the problem of conjugation difference between existing PE-X tubing and outer field oxidation prevention layer EVOH, the present invention through many experiments by hot melt adhesive 200 ~ 210 DEG C of meltings, bond effect is good.
Preferably, oxidation prevention layer is extruded by evoh layer extruder, and evoh layer extruder temperature setting stepwise is at 180 ~ 190 DEG C.
compared with prior art, the method preparing oxygen-resistance type PE-Xb tubing that the present invention proposes, manufacturing efficiency
high; The oxygen-resistance type PE-Xb mechanical properties of tubular goods proposed is good, high temperature resistant, cryogenic property good, oxidation prevention layer with
internal layer PE-Xb layer combines closely, and in use there will not be the phenomenon that oxidation prevention layer is separated with internal layer, quality is steady
fixed.
