Description
Technical field
The present invention relates to a kind of polyethylene water-feeding pipes, a kind of polyethylene water-feeding pipes with anti-microbial property and
Its preparation method.
Background technology
Feedwater pipeline many employings coating steel pipe in early days, but this type of pipeline is perishable, causes water pollution, supplies water in recent years
Pipeline is the most gradually replaced by plastic tube.Along with people are more and more higher to the requirement of water quality, there is the poly-second of excellent antibacterial performance
Alkene tubing has been increasingly becoming main flow.
Feedwater plastic tube mostly is polyvinyl piping materials at present, but the anti-microbial property of common polythene tubing is more weak, it is difficult to
Play antibacterial effect.In life-time service, the inner surface of tubing can adhere to and grow a considerable amount of microorganism, causes water quality dirty
Dye, the noxious bacteria in water can not effectively be killed and remove by common polythene tubing.
Current antibacterial is broadly divided into inorganic antiseptic, organic antibacterial agent and polymer antibacterial agent.Silver-containing antibacterial feed pipe
Although part has strong antibacterial ability, but its application in tubing article has a disadvantage in that 1, one oxidation stain makes antibacterial
Ability reduces or even lost efficacy, and antibacterial endurance is poor.2, make the mechanical property of tubing with argentiferous masterbatch significantly to decline, particularly
Hot strength and elongation at break the two index, therefore greatly limit its application on pressure tubing.3, argentiferous material becomes
This height, production cost is excessive, and marketing difficulty is big.4, argentiferous PE antibacterial pipe material tubing products is less susceptible to meet sanitation performance
Requirement.Organic antibacterial agent bactericidal effect is strong, but poor heat resistance, easily decompose, poor in timeliness；Polymer antibacterial agent is at organic anti-bacterial
Improve on the basis of agent, improve heat stability.
Summary of the invention
In view of problem present in above-mentioned technology, it is an object of the invention to provide a kind of polyethylene with anti-microbial property
Water-feeding pipes and preparation method thereof, the polyethylene feedwater piping that the method produces, there is good anti-microbial property, can be effectively
Kill except the microorganism grown in pipeline, reduce the safety guarantee that the secondary pollution during water delivery brings to the drinking-water of people.
For reaching above-mentioned purpose, the present invention uses following technical scheme: a kind of polyethylene with anti-microbial property feeds water
Tubing, its constituent is as follows:
Described complex antimicrobials is silver zeolite antimicrobial agent and the compound system of quaternary ammonium salt grafted polyethylene antibacterial.Current anti-
Microbial inoculum is broadly divided into inorganic antiseptic, organic antibacterial agent and polymer antibacterial agent.Silver-based inorganic antibacterial agent holds at high price, raw
Product cost is excessive, lacks competitiveness；And organic antibacterial agent bactericidal effect is strong, but poor heat resistance, easily decompose, poor in timeliness；High score
Sub-antibacterial improves on the basis of organic antibacterial agent and forms, and improves heat stability.The present invention uses inorganic antiseptic
With organic antibacterial agent compound system, improve the discoloration problem of silver zeolite antimicrobial agent, reduce production cost, there is antibacterial wide spectrum
Property, the advantage such as efficiently.Wherein, preferred compound proportion is 1:1.
High density polyethylene (HDPE) (HDPE): be a kind of degree of crystallinity thermoplastic resin high, nonpolar.High density polyethylene (HDPE) is nothing
Malicious, tasteless, the white particle of odorless, fusing point is about 130 DEG C, and relative density is 0.941～0.960.
Black masterbatch: be the one of Masterbatch, a kind of Masterbatch the most frequently used in plastic cement processing, black masterbatch is by a high proportion of
Pigment or additive and thermoplastic resin, through the plastic colorant of fine dispersion, coloring agent is had by its selected resin
Having good wet and peptizaiton, and have the good compatibility with being colored material, black masterbatch is widely used in plastics and adds
Industrial and commercial bank's industry, such as injection mo(u)lding, extrusion molding and blow molding etc..
PE100 level pelletize: PE100 is the grade that PE material (polyethylene) is divided according to international standard.Logical
Cross extruder grain unit pelletize.
There is described in present invention also offers the preparation method of anti-microbial property polyethylene water-feeding pipes, comprise the steps:
1) mix and blend: by a certain amount of, above-mentioned raw materials is carried out proportioning, is sequentially placed in blender, mixing time is 20
30min；
2) extruding pelletization, puts into the material of mix homogeneously and pelletize, temperature that extruder each section is blended in double screw extruder
Degree scope is: 175 DEG C-220 DEG C；
3) extrusion molding, by granule good for pelletize by single screw extrusion machine extrusion molding, prepares polyethylene water-feeding pipes,
Barrel zone temperature is 180 DEG C 220 DEG C, and the temperature of die orifice is 210 DEG C 230 DEG C.
The invention has the beneficial effects as follows: 1) manufacturing process is simple；2) inorganic antiseptic and organic antibacterial agent complex are used
System, reduces polyethylene antibiotic tubing production cost, has antibacterial smooth spectrality, the advantage such as efficiently, reduces two during water delivery
Secondary pollution, meets people's requirement in daily life to water quality.
