Description
Technical field
The present invention relates to a kind of nano anti-corrosive antibacterial plastic-metal composite pipe and manufacture method thereof.
Background technology
In daily life, people touch inevitably by virus or various article that bacterium polluted, thereby cause the generation of various diseases.Tap water is citizen's daily necessities, along with life running water flat improve constantly variation with environment, health care consciousness also strengthens gradually.The tap water quality situation is more and more paid close attention to by everybody, therefore, produces various goods with antibacterial, avoids the invasion and attack harm of pathogenic microorganism to human body, is that people are subjected to less or avoid unwanted bacteria infringement and sanatory developing direction.
Galvanized steel pipe in it zinc layer easily come off and also easy-to-rust of iron pipe surface, ferrobacillus growth, rust water, polluted water not only, and the inwall corrosion produces fouling, dross and the endoporus of inner chamber is dwindled, and flow resistance will increase like this, thereby makes its reduction in work-ing life.Though and pure plastic pipe in use is not subjected to flow-induced corrosion, make body also inclusion-free enter fluid, but plastic polymer is a chain-like macromolecule compound aggregates into the net high-polymer compound under the effect of catalyzer, owing to be heated, reason such as illumination, cause that easily harmful the variation taken place for macromolecular chain fracture and chemical structure, forms the ageing of plastics phenomenon.
So someone has proposed a kind of aluminum-plastic laminated tube, though aluminum-plastic laminated tube can reach health and healthy requirement, but can not kill the nuisances such as bacterium in the water, the new texture that application number is 01106225.8 for this reason, denomination of invention has proposed to have anti-microbial property for " a kind of inorganic nano antiseptic composite aluminium-plastic pipe ", its structure comprises plastic outer layer, outer adhesive layer, aluminium alloy layer, inner binder layer and contains the inner plastic of antiseptic-germicide, it is characterized in that used material of said antibacterial composite Al-plastic tube and weight percent are:
(1) contain the inner plastic 40-60% of inorganic nano antiseptic, wherein, inner plastic contains 0.2～3% inorganic nano antiseptic, and 97～99.8% vinyon is made;
(2) outer layer plastic 10～30%;
(3) aluminium alloy layer 10～40%;
(4) inside and outside binder layer 0.5～15%.
Though the water pipe of this structure has certain bactericidal property to water quality, but its outer field plastics are easy to occur catabiosis by ultraviolet irradiation, thereby make metallic aluminium directly be exposed to the external world, be the very active element of a kind of chemical property because of metallic aluminium itself again, perishable, like this time long slightly, water pipe will break because of hydraulic pressure, and will shorten the work-ing life of multiple-unit tube, causes damage to the user.This multiple-unit tube kind that to also have a shortcoming be its multiple-unit tube is few in addition, just adopt a kind of metal, be the main body framework of metallic aluminium as multiple-unit tube, and the metallic aluminium material is softer, the intensity of this multiple-unit tube does not reach relative national standards, can not be applied on the outdoor water pipe, be not suitable on the industrial large-scale pipeline yet, therefore its use range is narrower, and kind is single, all can bring certain restriction to the multiple-unit tube Products Development and to the development of enterprise like this, also limit its applying on market.On the other hand, a lot of buildings need to use high strength, pollution-free, the water pipe of health environment-friendly, also need strength ratio bigger in some industrial production occasions, the pipeline of health environment-friendly, particularly in the occasion of the anti-certain pressure of needs, especially true, so its structure awaits to improve, at last, owing to adopt the tubing of different skeletons, certainly will cause the production method of producing this multiple-unit tube must also obtain upgrading, because the production method of traditional aluminum-plastic laminated tube can not be produced at the multiple-unit tube that new employing hard tube is done skeleton and be used, so exploitation makes new advances, technology is simple, it is very important that composite tube production method easy to make seems.
Summary of the invention
