Description
Technical field
The invention belongs to supply water pipe technical field, and in particular to a kind of antibacterial PE feed pipes.
Background technology
Polyethylene (polyethylene, abbreviation PE) is a kind of aggregated obtained thermoplastic resin of ethene.Industrially,
Also the copolymer of ethene and a small amount of alpha-olefin is included.Polyethylene odorless, nontoxic, feel ceraceous, with excellent resistance to low temperature
(minimum reachable -100~-70 DEG C of temperature in use), chemical stability is good, is resistant to the erosion of most of soda acids (intolerant to oxidation
The acid of property).Common solvent is not dissolved under normal temperature, water imbibition is small, and electrical insulating property is excellent.
PE pipes are mainly for delivery of gaseous artificial coal gas, natural gas, liquefied petroleum, also blowdown, and construction technology is simple.
PE tubing has intensity high, and high temperature resistant is anticorrosive, nontoxic, wear-resisting, there is certain pliability performance.The molecule of polyethylene is long-chain
Linear structure or branch structure, are typical crystalline polymer.In the solid state, crystalline portion coexists with unformed.Crystallinity
Different depending on processing conditions and former treatment conditions, generally, density high-crystallinity is bigger, and LDPE crystallinity is usually 55-
65%, HDPE crystallinity are 80-90%.Polyethylene is typical thermoplastic, has nontoxic, odorless due to it, tasteless
Feature, receives to popularize and uses.But in some rugged environments, in use, often produced inside and outside tubing
Endophytic bacteria grows.
In some present production technologies, some antiseptics, ultraviolet screener or anti-are added in synthetic material process
Some auxiliary agents such as oxygen agent delay its aging to lift its antibiotic property, but can not still meet use requirement.Chinese patent
200410037200.0 provide a kind of preparation method of antibacterial PVC-U feed pipes, include mixing, the twin-screw extrusion of material
Machine extrusion, vacuum cooled sizing, fixed length cutting, flare formation, inspection, packaging and storage.It contain PVC-U resins 200~220,
Silver-series antibacterial agent 1.5~2.6, filler 5~12, heat stabilizer 0.6~1.2, lubricant 2.8~5.0, colouring agent 0.3~
0.65.The PVC-U antibacterial pipe materials of invention production have excellent physical and mechanical properties and anti-microbial property, and antibiotic rate reaches
More than 98%, suppress bacterial reproduction while can guarantee that water delivery, to avoid secondary pollution of water；And do not increase any equipment, into
This is cheap.But, the antiseptic is simply directly not ideal enough using polyethylene pipe effect.
The content of the invention
The present invention proposes a kind of antibacterial PE feed pipes, and not only antimicrobial efficiency is up to more than 99%, Er Qiekang the feed pipe
The bacterium cycle is long.
The technical proposal of the invention is realized in this way：
A kind of antibacterial PE feed pipes, according to the number of parts by weight, including following raw material is made：

1~3 part of~24 parts, 1~3 part of lubricant, 2~5 parts of dispersant and anti-impact modifier；Wherein, complex antimicrobials are by quality
Than for 2~4:1 inorganic antibacterial material and organic anti-bacterial material composition, inorganic antibacterial material is by limonite ball powder, zeolite powder, oxygen
Change zinc to constitute with Nano Silver.
Preferably, calculated according to mass percent, inorganic antibacterial material is by 40~60% limonite ball powder, 20~30% boilings
Stone flour, 10~20% zinc oxide and 6~12% Nano Silvers are constituted.
Preferably, organic anti-bacterial material is normal-butyl BIT or methylisothiazolinone.
Preferably, lubricant is two kinds in calcium stearate, stearic acid, paraffin, microwax, OPE and PE waxes
Or two or more mixtures.
Preferably, dispersant is poly- (methylacryoyloxyethyl ammonium chloride-hydroxyalkyl acrylate) copolymer.
Preferably, antioxidant is phosphite ester kind antioxidant.
The antibacterial PE feed pipes of the present invention can be prepared by existing melting method.
Beneficial effects of the present invention：
Limonite ball has good mineralization, and the anion discharged when handling water is on a 1200/cubic centimetre left sides
The right side, can effectively kill bacterium in water, increase oxygen in water, easily remove human body dirt, dispelling fatigue.Nano Silver, oxidation
Zinc and zeolite powder：In the excellent Nano Silver of the zeolite structured interior addition anti-microbial property of three-dimensional skeletal structure, zinc ion so that silver,
The permanently effective controlled release of zinc ion energy, reaches long acting antibiotic effect.
Organic antibacterial agent, it can be adsorbed on the cell membrane of microorganism, then penetration cell wall, into intracellular and and born of the same parents
Interior lipid and albumen qualitative response, are allowed to change, so as to cause the cellular content of low molecule amount, to flow out to microorganism dead
Die.It has very strong inhibitory or killing effect to all kinds of Gram-positives and negative bacterium, fungi, saccharomycete.
