Abstract
An inorganic nanometer silver-zinc composite transparent antiseptic preferably consists of the following components in parts by mass: 800-12000 parts of water, 0.1-8 parts of an alkali inorganic salt, 1-12 parts of an acid metal-ion complexing agent, 0.01-1 part of a silver salt, 0.02-5 parts of a zinc salt, 1-16 parts of an alkali metal-ion complexing agent, 0.3-5 parts of a chelate coupling agent, 0.2-5 parts of a dispersant, and 0.5-7 parts of a heterocyclic metal-ion corrosion inhibitor. The invention also provides a preparation method of the antiseptic. The preparation method comprises: making the silver salt and the zinc salt in the solution react with the alkali metal-ion complexing agent to form a stable complex, adding into a diluents of the alkali inorganic salt and the acid metal-ion complexing agent for secondary protective complexation, then adding the chelate coupling agent and the dispersant to avoid generation of particle agglomerated precipitates, and finally adding the heterocyclic metal-ion corrosion inhibitor for resisting oxidation, resisting ultraviolet and preventing color changes, to obtain the colorless transparent silver-zinc composite antiseptic.
Description
Technical field
The invention belongs to antibiotic and technical field, especially relate to a kind of inorganic nano-silver zinc composite transparent antibacterial agent and preparation method thereof.
Background technology
Environment for human survival exists the microorganism of various harmful healths, productive life to the mankind produces many harmful effects, and particularly after SARS occurred, the mankind found simultaneously, many noxious bacterias morph, and rely on existing medical means often to be caught unprepared.The continuous renewal of antimicrobial technology is imperative.The antibacterial ability of silver is very strong and have the broad-spectrum sterilization effect, can not produce toxin in the human body accumulation again, a long time ago, just is used as the antibacterial activity material.The nanometer-level silver ion has higher surface energy and more contact area, has higher antibacterial activity, and bacterium just loses activity 6 seconds after contacting with Nano Silver.
At present, existing single nanometer silver antimicrobial technology, the antibacterial agent that this method is produced is fine to the killing effect of bacterium, but undesirable to the fungi bactericidal effect.And silver is single antibacterial agent, and yellowing resistance can be poor.As the patent No.: 201,210,553,614 1 kinds of nano silver colloidal sol antibacterial agents and preparation method thereof, the patent No.: the preparation method of 200,710,133,403 1 kinds of nano silver antimicrobials, the patent No.: 201010596742.7 1 kinds of nano silver antimicrobials and preparation method thereof, above 3 kinds is all single nanometer silver antimicrobial technology, only have the release of silver ion that anti-microbial property is just arranged, antimycotic undesirable, and along with silver ion constantly dissociates out, longer xanthochromia performance of time worse and worse on white object.
" silver and silver zinc complex antibacterial agent and application thereof " delivered in " Committee of Experts's inaugural meeting of Chinese Plastics processing industry association and plastic new material in 2005, new technology international symposium collection of thesis " for Mr. Li Bizhong, it is mainly set forth, and with zeolite, does carrier and carries out ion exchange and obtain carrier silver zinc complex antibacterial agent; " preparation of zinc-silver compounding sea afrodite antibacterial agent " is in May, 2010 Lu Yu of Chengdu University of Technology master thesis in addition, is also carrier silver zinc complex antibacterial agent.Their shortcoming is, (1) is solid powder material, and the scope of application is limited to.(2) in process of production, carry out ion exchange, heating process is arranged, cause energy loss, and increased time production cycle.
