Titanate ester or silane coupling agent 0.2～2% and low sub-weight northylen wax 0.2～2% by the anti-bacterial powder total amount of inorganic organic mixing is added in the anti-bacterial powder of inorganic organic mixing, and immersion treatment 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 antibacterial activity pulvis of inorganic organic mixing;
Above-mentioned inorganic antiseptic be a kind of contain with argent, zinc or copper be main antimicrobial component with inorganic oxide, titanium oxide, silica, zeolite, clay etc. are the mixture of the inorganic powder of carrier; Organic antibacterial agent 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; Mix according to the above ratio between inorganic antiseptic and the organic antibacterial agent.
(2) preparation of the antibacterial plastic concentrate of inorganic organic mixing:
The antibacterial activity pulvis of above-mentioned inorganic organic mixing is added in the resin in 5～30% ratio of weight resin, mixes with homogenizer, melt extrudes granulation through twin-screw, can make the antibacterial plastic concentrate of inorganic organic mixing.
(3) preparation of the antibacterial composite Al-plastic tube of inorganic organic mixing:
The antibacterial plastic concentrate of inorganic organic mixing 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 antibacterial composite Al-plastic tube of the said inorganic organic mixing of the present invention.
The antibacterial composite Al-plastic tube of inorganic organic mixing of the present invention, based on antibiotic plastic internal layer with the inorganic organic mixing of one deck, 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 or organic single antibacterial composite Al-plastic tube, it is lasting that the antimicrobial agent of inorganic organic mixing combines inorganic antiseptic, the organic antibacterial agent consumption is little, is uniformly dispersed, and antibacterial effect is higher than inorganic or organic antibacterial agent.
