Abstract
The present invention discloses an antibacterial composite aluminium-plastic pipe which is composed of a plastic outer layer, an outer adhesive layer, an aluminium alloy layer, an inner adhesive layer and a plastic inner layer containing inorganic nanon antibacterial agents. Because the antibacterial composite aluminium-plastic pipe of the present invention has the antibacterial plastic inner layer, can kill scores of cultures, such as bacteria, eumycetes, mildew, etc., and has the advantages of obvious bacteriostasis effect of escherichia coli, gold staphylococci, candida albicans, etc. and lasting antibacterial effect. The present invention can satisfy the antibacterial requirement for water supply pipelines in daily life.
Description
Technical field
The invention belongs to the building pipe technical field, relate to a kind of inorganic nano antiseptic composite aluminium-plastic pipe.
Background technique
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 aluminium-plastic composite pipe 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 aluminium-plastic composite pipe, 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 aluminium-plastic composite pipe reach health and health requirements, usually the method that adopts is to select for use the avirulent material polyethylene resin of high-purity to make aluminium-plastic composite pipe, though the aluminium-plastic composite pipe of Xiao Shouing can reach health and healthy requirement in the market, but can not kill the harmful substances 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 composite pipe of the harmful substances such as bacterium in the water again, be the product that people institute is very expected.
Summary of the invention
The object of the present invention is to provide a kind of inorganic nano antiseptic composite aluminium-plastic pipe, adopt inorganic nano antiseptic to combine the inner plastic of making aluminium-plastic composite pipe with plastics, to satisfy people water supply line health and healthy needs.
Technological scheme of the present invention is achieved in that
With the inorganic nano antiseptic is that antimicrobial agent mixes with plastics after surperficial special processing, extrude through twin-screw and to cause the inorganic nano antiseptic masterbatch, the inorganic nano antiseptic masterbatch is joined in the aluminium-plastic composite pipe inner plastic in proportion, produce the aluminium-plastic composite pipe of internal layer organic/inorganic nano antibacterial effect by plastic-aluminum combined production line.
The structure of the said a kind of inorganic nano antiseptic composite aluminium-plastic 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 inorganic nano antiseptic successively, it is characterized in that used material of inorganic nano antiseptic composite aluminium-plastic pipe and weight percentage are:
1) contain the inner plastic 40～60% of antimicrobial agent, wherein inner plastic contains 0.2～3% inorganic nano antiseptic, 97～99.8% polyvinyl plastics;
The agent of inorganic sodium nano antibacterial be a kind of contain with argent, zinc or copper be main antimicrobial component with inorganic nanometer oxide, 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 polyethylene 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 sticker layer 0.5～15%, said inside and outside sticker layer are to be made by a kind of thermosol that is prepared by the polyethylene 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 inorganic nano antiseptic active powder:
Titanate ester or silane coupling agent are pressed in 0.2～2% and low molecular weight polyethylene wax 0.2～2% adding inorganic nano antiseptic powder of inorganic nano antiseptic powder total amount, and in the normal temperature high-speed stirring mixer, mix and carried out immersion treatment in 1～2 minute, dried 1～2 hour down at 100～130 ℃ then, promptly make the inorganic nano antiseptic active powder;
Above-mentioned inorganic nano antiseptic powder is to be main antimicrobial component with argent, zinc or copper, and with inorganic nanometer oxide, any is the inorganic nano antiseptic powder of carrier as titanium oxide, silica, zeolite, clay etc.
(2) preparation of inorganic nano antiseptic masterbatch:
Above-mentioned inorganic nano antiseptic 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 inorganic nano antiseptic masterbatch.
(3) preparation of inorganic nano antiseptic composite aluminium-plastic pipe:
The inorganic nano antiseptic masterbatch is added in the aluminium-plastic composite pipe inner layer polyethylene resin, addition is 1～10% (in weight resin), the best is 2～6%, adopt butt welding or lap welding plastic-aluminum pipe production line to prepare aluminium-plastic composite pipe, products obtained therefrom is the said inorganic nano antiseptic composite aluminium-plastic pipe of the present invention.
Inorganic nano antiseptic composite aluminium-plastic pipe of the present invention, based on having one deck inorganic nano antiseptic 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 inorganic nano level antimicrobial particles is little, is uniformly dispersed, and antibacterial effect is higher than inorganic antiseptic.
