Description
Technical field
The present invention relates to a kind of fungusproof anti-corrosion agent, be specifically related to the agent of a kind of environment-friendly type composite mildewproof anticorrosive and application thereof, environmentally friendly fungusproof anti-corrosion agent of the present invention, decorticating mammal, vertebrate (reptile, fish, bird etc.) and mollusk sample time, long-term fungus-proof antisepsis specimens preserving and application are carried out to its skin and tissue, belongs to fungusproof anti-corrosion agent technical field.
Background technology
Preservative treatment is very important step in preparation of specimen's process, the preservation life-span of direct decision sample, but in actual environment, the samples such as miscellaneous animal, plant, historical relic are subject to infringement the most serious because of the harm of mould, sample is shortened dramatically service life, also causes huge economic loss simultaneously.The Poisons such as arsenic are used in traditional preservation formulations, preservative itself is dangerous on the one hand, severe contamination is caused to assanation and safety, there is management and control in country to this kind of extremely toxic substance on the other hand, use inconvenience and also cost high, the concrete composition of especially external antiseptin is also in confidential state.
Sample mould mainly contains 22 bacterial strains belonging to aspergillus and Penicillium, include aspergillus fumigatus, rod aspergillus, the moulds such as aspergillus niger, current sample dissipation mould method only uses chemicals method, mainly contain formalin-potassium permanganate fumigation, O-SyL thymol, N-phenylsalicylamide etc., use the Poisons such as arsenic in most preservation formulations simultaneously, not only can not accomplish the effect controlling sample mould completely. staff and the healthy of visitor are caused serious injury simultaneously, lack the fungusproof anti-corrosion agent that sample is prepared in environmentally friendly being applied to, therefore safety non-toxic is found, non-secondary pollution, the sample fungusproof anti-corrosion agent of safety and environmental protection has been extremely urgent.
The antifungal mechanism of shitosan and antagonistic property aspect, the conclusion that different researchers draws but is not quite similar.The bacteriostasis of Chitosan-phospholipid complex presents different results along with the change of himself and environmental condition, analyze its main cause: after (1) shitosan is dissolved in acid, become a kind of cationic biological flocculant, in flocculation process, make somatic cells coagulation, macromolecular chain is intensive in microorganism surface, forms one deck polymeric membrane, affect the absorption of bacterium to nutriment, stop the excretion of metabolic waste, cause the metabolic disturbance of thalline, thus play sterilization and antibacterial effect; (2) Small molecular shitosan (MW<5000kDa) can permeate through cell membranes, enter in microbial cell, combine with material electronegative in cell (mainly protein and nucleic acid), the normal physiological function of cell (such as DNA copies the synthesis etc. with protein) is affected, causes microbial death; (3) macromolecular shitosan is adsorbed on microbial cell surface, forms one deck polymeric membrane, prevents nutriment to intracellular transport, thus play sterilization and bacteriostasis effect; (4) interaction between the positive charge of shitosan and the negative electrical charge on microbial cell film surface, changes the permeability of microbial cell film, causes microbial cell dead; (5) shitosan is as a kind of chelating agent, optionally the metal ion that plays a crucial role to growth of microorganism of chelating, thus suppresses microbial growth; May be that shitosan has one of reason of anti-corrosive fresh-keeping function; (6) shitosan can the chitinase activity of activating microorganisms itself, and when chitosan concentration is enough high, the chitinase of microorganism is too expressed, and causes the chitinous degraded of himself cell wall, thus damaging cells wall.
Shitosan is also different for the inhibiting mechanism of different microorganisms: (1) is for Gram-negative bacteria G-(E. coli), mainly because micromolecular chitosan penetrating enters in microbial cell, electronegative cytoplasm in adherent cell, and there is flocculation, upset the normal physiological activity of cell, thus kill bacteria; (2) and for gram-positive bacteria G+ (staphylococcus aureus), mainly because macromolecular shitosan is adsorbed on microbial cell surface, form one deck polymeric membrane, prevent nutriment to intracellular transport, thus play sterilization and bacteriostasis effect.
Particle diameter is accomplished nano level Powdered silver-colored simple substance by Nano Silver exactly, particle diameter is less than 100nm, general between 25-50nm, nano-Ag particles directly enters thalline and oxygen metabolism enzyme (-SH) combines, block the unique mechanism of action that respiratory metabolism makes thalline be choked to death, the microorganism such as most of bacteriums, fungi, mould, spore be in contact with it can be killed.Through experiment, all kinds of gram-negative Salmonella, more than 650 kind of bacterium such as gram sun Salmonella, fungi, gonococcus, chlamydia trachomatis etc. were killed in several minutes, broad-spectrum sterilization and without any drug resistance.The performance of Nano Silver and its particle diameter have direct relation, and particle diameter is less, and valence state is higher, and bactericidal property is stronger, and the nano-Ag particles of 10nm size directly can kill bacterium rapidly, makes it lose fertility.Nano-Ag particles has superpower permeability, subcutaneous 2nm sterilization can be infiltrated rapidly, good permanent bactericidal action is all had to common bacteria, stubborn bacteria, drug-resistant bacteria and the fungus-caused tissue infection compared with depths, and Nano Silver is nontoxic, tasteless, pollution-free, without skin irritation, non-carcinogenesis, does not injure human body.
It is commonplace that Nano Silver is used for health care goods, but the bibliographical information of the making that there is not yet for sample and preservation aspect.Along with the continuous maturation of nano silver preparation technology, the cost of Nano Silver declines greatly, and therefore price is constantly being reduced to reasonable level, uses it for the making of sample and preserves and will become possibility.
Chinese invention " a kind of anticorrosive Chinese medicine preparation and application thereof ", application number 201010589320.7 discloses a kind of preservative treatment of preservative for sample of Chinese drug preparation, but shitosan and Nano Silver compound be have not been reported as sample fungusproof anti-corrosion agent.
