The present invention can satisfy the antibacterial requirement for water supply pipelines in daily life.
Description
The invention belongs to the building pipe technical field, relate to a kind of antibacterial composite aluminium-plastics pipe.
Galvanized iron conduit commonly used was made water supply pipeline in the home dwelling in the past, and its shortcoming is a polluted water, and the life-span is short, and PAP has overcome the galvanized iron conduit polluted water, and pure shortcoming of moulding the pipe intensity difference combines the high strength of metal tube, the advantage of the pollution-free water quality of plastic tube.
The newly-built dwelling house in many cities is forbidden galvanized iron conduit comprehensively and is made water supply pipeline, and the employing PAP, raising along with people's living standard, people are also more and more higher to the requirement of health and health, therefore, the plastic-aluminum pipe that meets health and health requirements has become the focus that people pay close attention to, in order to make PAP reach health and health requirements, usually the method that adopts is to select for use the avirulent material polyvinyl resin of high-purity to make PAP, though the PAP of Xiao Shouing can reach health and healthy requirement in the market, but can not kill the nuisances such as bacterium in the water, therefore a kind of both met health and healthy requirement are provided, can kill simultaneously the antiseptic aluminium-plastic material multiple tube of the nuisances such as bacterium in the water again, be the product that people institute is very expected.
The object of the present invention is to provide a kind of antibacterial composite aluminium-plastics pipe, utilize organic bactericide to combine the plastics of making PAP with plastics, to satisfy people water supply line health and healthy needs.
Technical scheme of the present invention is achieved in that
With the organic antibacterial agent is that antiseptic mixes with plastics after surperficial specially treated, extrude through twin-screw and to cause the organic anti-bacterial masterbatch, the organic anti-bacterial masterbatch is joined in the PAP inner plastic in proportion, produce the PAP that internal layer has the organic anti-bacterial effect by plastic-aluminum combined production line.
The structure of the said antibacterial composite aluminium-plastics pipe of the present invention, form by plastic outer layer, outer adhesive layer, aluminium alloy layer, inner binder layer and the inner plastic that contains organic antibacterial agent successively, it is characterized in that used material of antibacterial composite aluminium-plastics pipe and percentage by weight are:
1) contain the inner plastic 40~60% of antiseptic, wherein inner plastic contains 0.2~3% organic antibacterial agent, 97~99.8% vinyon;
The agent of inorganic sodium nano antibacterial be a kind of contain with argent, zinc or copper be main antimicrobial component with organic oxygen compound, titanium oxide, silica, zeolite, clay etc. be the mixture of the inorganic powder of carrier, have this product on the market;
2) outer layer plastic 10~30%, and said plastic outer layer is made by polyvinyl resin;
3) aluminium alloy layer 10~40%, and the said aluminium alloy layer trade mark is 8011A, 1145,1235,1100,1200,1050,1060, and state is the high-grade soft aluminium of H22 or 0 state, the annealing degrease;
4) inside and outside adhesive phase 0.5~15%, said inside and outside adhesive phase are to be made by a kind of hot melt adhesive that is prepared by the polyvinyl resin of maleic anhydride or maleic acid graft modification.
The plastic-aluminum combined tube preparation method that now contains antibiotic pulvis is as follows:
(1) preparation of organic anti-bacterial active powder:
Titanate ester or silane coupling agent are pressed in organic anti-bacterial powder total amount 0.2~2% and low sub-weight northylen wax 0.2~2% adding organic anti-bacterial powder, and impregnation process was carried out in low-medium speed stirring at normal temperatures in 1~2 minute, dried 1~2 hour down at 90~120 ℃ then, promptly make the organic anti-bacterial active powder;
Above-mentioned organic anti-bacterial powder is Triclosan, N-(trihalomethyl sulfo-) phthalimide and corresponding tetrahydro derivative thereof, N-(trichloromethylthio)-4-cyclohexene-1,2-dicarbapentaborane acid imide, diphenyl antimony-2 ethyl hexanoic acid ester, 10, the two phenoxazine arsines of 10-oxo, two (oxine) copper.
(2) preparation of organic anti-bacterial masterbatch:
Above-mentioned organic anti-bacterial active powder is added in the resin in 5~30% ratio of weight resin, mixes with homogenizer, melt extrudes granulation through twin-screw, can make the organic anti-bacterial masterbatch.
(3) preparation of antibacterial composite aluminium-plastics pipe:
The organic anti-bacterial masterbatch is added in the PAP inner layer polyethylene resin, addition is 1~10% (in weight resin), the best is 2~6%, adopts butt welding or overlap welding plastic-aluminum pipe production line to prepare PAP, and products obtained therefrom is the said antibacterial composite aluminium-plastics pipe of the present invention.
Antibacterial composite aluminium-plastics pipe of the present invention, based on having one deck organic anti-bacterial inner plastic, can kill bacteria, tens kinds of bacterial classifications such as fungi, mould, obvious to the fungistatic effect of Escherichia coli, gold-coloured staphylococci, Candida albicans etc.; Antibacterial effect is lasting, can satisfy the antibiotic requirement of people's daily life, compares with inorganic antiseptic composite aluminium-plastic pipe, and organic antibacterial agent and resin compatible are good, are uniformly dispersed, and antibacterial effect is higher than inorganic antiseptic.
Below in conjunction with embodiment the present invention is further described below.
