Abstract
The invention relates to the technical field of pipelines, in particular to a pipe. A non-stick-oil scaling-free antibacterial oxygen-barrier double-rejection pipe comprises a pipe body, wherein the pipe body comprises a polypropylene random copolymer (PPR) inner pipe layer and a PPR outer pipe layer, wherein a lyophobic layer is coated on the inner surface of the PPR inner pipe layer; and the lyophobic layer is formed by coating lyophobic nano composite paint. The double-rejection pipe has an oxygen barrier effect and prevents the bacteria on the inner wall of the pipe and scales from being attached onto the inner wall of the pipe.
Description
Technical field
The present invention relates to the pipe technology field, be specifically related to a kind of tubing.
Background technique
The advantage that atactic copolymerized polypropene (PP-R) pipe is light except the quality that possesses general plastic tube, thermal conductivity is low, thermal loss is little, easy for installation, also have nontoxic, health, the advantage of heat resistance and heat preservation energy-saving, long service life preferably, thereby be widely used in cold and hot water supply system, purified water supply system and other pipe-line systems of building.Yet in use, oxygen in the atmosphere infiltrates pipe-line system inside by tube wall easily, and make pipe fitting that the metallic material that links to each other with aforementioned tubes makes, and other parts corrosions, and owing to the infiltration of oxygen has caused growing of microorganism, the water quality of carrying is caused harmful effect, also form incrustation easily and block pipeline.
Summary of the invention
The object of the invention is to, provide a kind of oily dirt free non-scaling antibacterial oxygen-resistance two pipes of refusing, to address the above problem.
Technical problem solved by the invention can realize by the following technical solutions:
The two pipes of refusing of oily dirt free non-scaling antibacterial oxygen-resistance comprise a body, it is characterized in that described body comprises a PPR (atactic copolymerized polypropene) inner tube layer, a PPR external tube layer, and the internal surface of described PPR inner tube layer is coated with drainage blanket;
Described drainage blanket adopts the dewatering nano composite coating to apply and forms.
Described drainage blanket adopts nano titanium oxide to form concavo-convex alternate interface nano-structure in the internal surface coating of described PPR inner tube layer.
Because can adsorption gas molecule on the surface of nano-scale indentation, and make it stable adhere to and exist, so formed the stable gas membrane of one deck on the surface, profit can't directly be contacted with the surface of PPR inner tube layer, so that incrustation scale is non-cohesive, thereby so that the surface of PPR inner tube layer has oleophobic, hydrophoby, drainage blanket has utilized lotus leaf effect, have hydrophobic, self-cleaning surface, when the liquid process was coated with the PPR inner tube layer of drainage blanket, because lotus leaf effect, drainage blanket was hydrophobic, bacterium in the liquid can't be attached to drainage blanket, has realized the purpose that antibacterium grows; In addition, because liquid can't rest on drainage blanket, when liquid flows through drainage blanket, also taken away the dirt on the drainage blanket, so that drainage blanket is not easy to form incrustation scale, incrustation scale can't be attached to drainage blanket, so the present invention adopts drainage blanket to realize two effects of refusing.
Described drainage blanket can be that nano silicon applies the drainage blanket that forms according to the process step of setting.
Described PPR inner tube layer is the PPR inner tube layer that includes nano anti-biotic material.
Described PPR inner tube layer includes nano anti-biotic material, has antibacterial action, can eliminate the bacteriums such as staphylococcus aureus, staphylococcus albus, candida albicans, hay bacillus, Escherichia coli, gonococcus, Halophiles, pseudomonas aeruginosa, typhoid bacillus, beta streptococcus to a certain extent, pipe fitting inner wall has been played good self-cleaning action, can effectively prevent pipe fitting inner wall knot dirt, guarantee that pipe fitting inner wall is smooth.Therefore the present invention can be used as pipe member, can also be used as the oil transportation pipe fitting.In the using process as pipe member, because nano anti-biotic material has antibacterial action, can effectively stop bacteria breed, purify water, thus not only can be used as the cold water water pipe, can also be as the purified water water pipe.
Described PPR inner tube layer is the PPR inner tube layer that contains inorganic antiseptic.Inorganic antiseptic can adopt silver ion class antimicrobial agent, Zinc-oxide-based antimicrobial agent, cupric oxide class antimicrobial agent, ammonium dihydrogen phosphate class antimicrobial agent, lithium carbonate class antimicrobial agent etc.
As a kind of preferred version, described PPR inner tube layer is the PPR inner tube layer that contains nano silver antibacterial material.
Described PPR inner tube layer adopts the PPR inner tube layer that contains oxygen barrier material, and described oxygen barrier material adopts ethylene-vinyl alcohol copolymer (EVOH).Oxygen barrier material can reduce the transmittance of oxygen effectively, and one side can suppress the pipe fitting wall bacteria, algae grows, and can reduce on the other hand the oxidation rate of pipe fitting, prolongs the life-span of pipe fitting.
Described PPR inner tube layer can also be the antibacterial oxygen-resistance PPR layer that is mixed with oxygen barrier material and nano silver antibacterial material.Described oxygen barrier material preferably adopts ethylene-vinyl alcohol copolymer (EVOH).
Described antibacterial oxygen-resistance PPR layer, described drainage blanket consist of two material layers of refusing together.
Also be provided with the enhancement layer that a glass fibre is made between described PPR inner tube layer and the described PPR external tube layer.The adding of glass fibre has improved the two intensity of refusing pipe of oily dirt free non-scaling antibacterial oxygen-resistance, the two coefficient of linear expansion of refusing pipe of oily dirt free non-scaling antibacterial oxygen-resistance have been reduced simultaneously, thereby the two temperature tolerances of refusing pipe of oily dirt free non-scaling antibacterial oxygen-resistance have been increased, improve the waist situation of collapsing in the pipe fitting using process, and then enlarged the two Applicable scope of refusing pipe of oily dirt free non-scaling antibacterial oxygen-resistance.
Described glass fibre can adopt length to cut fiber, also can adopt chopped strand, also can adopt long blend fiber of cutting fiber and chopped strand composition, preferably adopts chopped strand.Chopped strand is cut fiber than length and is had more excellent tensile strength, is conducive to improve performance of the present invention.Also can adopt other reinforcing materials to make described enhancement layer, such as carbon fiber or other fibers.
The present invention is by putting into material one main extruder, two auxiliary extruders, and described PPR inner tube layer, PPR external tube layer, enhancement layer co-extrusion under the setting temperature form a three-layer co-extruded PPR pipe.
Beneficial effect: the invention provides a kind ofly have resistance oxygen effect, the pipe material inner wall antibacterium grows and the inadhering two pipes of refusing of incrustation scale.
