Abstract
The antiseptic medical breathing mask is produced through mixing mixed crystalline titania below 50 nm, nano zinc oxide, dispersant, adhesive and water to form solution or emulsion; and painting the solution or emulsion to the outer layer of breathing mask. It has good ventilation, and bactericidal and bacteriostasis functions, and may be used by doctor, patient and other people.
Description
One, technical field
This patent is a kind of novel, preparation method of antimicrobial form medical protective mask efficiently.Belong to public health and daily life field.
Two, background technology
The outburst of spring and summer in this year " SARS " makes the economic development of human life security and society be subjected to great impact.Because the sudden and infectiousness of such disease, it is anti-that people's air defense is unequal to.Particularly " SARS " more caused fear to medical worker's higher infection rate on people.
Lazaretto ward medical personnel's safeguard procedures mainly wait and carry out by wearing protective garment, protective mask at present, but present widely used cotton cloth respirator can only play simple absorption and iris action; Though and the barriering effect of rubber, high score subclass protective articles is good, airtight, particularly can not be used for the easiest link---the mouth mask that infects of causing, and these protective articles generally do not possess bactericidal effect.Therefore how effectively to cut off the route of transmission, reduce infection rate effectively, seem particularly important.
Though the medical protective mask hole that makes with nanofiber is little, the rejection rate of dust, bacterium has been reached more than 99%, its bactericidal action is not obvious, and cost is higher.
Chinese patent 01269217 is a kind of antibacterial antitoxic garment that utilizes high-density non-woven fabrics and plastic sheeting to make, and is used for the protecting human body of health and epidemic prevention, medical treatment, import and export quarantine, the condition of a disaster epidemic-stricken area, research department, contact poisonous and harmful substance and pathogenic microorganism environment.It has upper garment and the blast cap glasses are connected as a single entity, and blast cap and glasses are connected as a single entity, and blast cap mouth, cuff are tightened by rubber strip, and the chest belly of upper garment and sleeve surface are coated with plastic sheeting.Trousers and shoe cover are connected as a single entity, and the surface is coated with plastic sheeting, and waist, ankle have rope band to fasten.Supporting mouth mask, emgloves can make nose, mouth, hand tightly be protected, and human body and nuisance are effectively isolated.Its shortcoming is airtight, can not dress for a long time, and cost is very high, can not popularly use.
Chinese patent 03109779 is a kind of sterilization anti-poison respirator and preparation method thereof, outer face mask, velcro, internal layer, mouth mask rope, auxiliary soft metal thin slice of finalizing the design by mouth mask are formed, the internal layer of mouth mask is equipped with the sorbing material of the high-specific surface area that covers carrying metal ion, a kind of gas permeability, filter efficiency height that can use under the condition of high-concentration suspension particle, bacterium, virus is provided, has sterilization, a mouth mask of the toxic effect of going out fruit.But this class mouth mask has been owing to having used the particle interlayer to have to guarantee its comfort level with soft foil metal, thereby makes trouble, the cost height, and be difficult for washing.
Three, Fa Ming content
The present invention is a kind of protective mask with nano photo-catalytic effect that proposes according to the deficiencies in the prior art, be characterized in both having high bacterium rejection rate, significantly antibacterial and sterilizing function is arranged again, and make simple, easy to use, the medical worker and the patient that are particularly suitable for lazaretto ward use.
The objective of the invention is to realize by following technical measures:
Get 0.5～30 part of particle diameter less than the mixed crystal type nanometer titanium dioxide (wherein anatase titanium dioxide 85%～98%, rutile titanium dioxide 2%～15%) of 50nm, 0.5～10 part of nano-ZnO, 0.5～5 part of dispersant, 0.5～15 part of binding agent and 40～90 parts of pure water.Its best proportioning (quality) is: mixed crystal type nanometer titanium dioxide 10 parts of (wherein rutile content is 7.5%, and anatase content is 92.5%), 5 parts of nano zine oxides, 1 part of dispersant, 8 parts of binding agents, 76 parts of distilled water.Wherein said dispersant is alkylbenzenesulfonate, calgon or their mixture, and described binding agent is silane or starch.
Its preparation method follows these steps to carry out: (1) gets the following unformed titanium dioxide of 50nm of the precipitation method or sol method preparation, obtains mixed crystal type nanometer titanium dioxide in calcining under 600～800 ℃ after 1～2 hour; (2) press that mass ratio obtains homodisperse colloidal sol with 0.5～30 part of particle diameter after less than the mixed crystal type nanometer titanium dioxide (wherein anatase titanium dioxide 85%～98%, rutile titanium dioxide 2%～15%) of 50nm, 0.5～10 part of nano-ZnO, 0.5～5 part of dispersant, 0.5～15 part of binding agent and 40～90 parts of distilled water high-speed stirred or emulsion is standby; (3) get health gauze mask commonly used, put into vacuumfilter one by one and spread out and carry out vacuum filtration after paving, with writing brush and soft small brushes colloidal sol is brushed on mouth mask simultaneously; (4) promptly obtain the antimicrobial form medical protective mask after the mouth mask oven dry after will brushing evenly.
The present invention compared with prior art has the following advantages:
1, adopt the following mixed crystal type titanium dioxide (wherein anatase titanium dioxide accounts for 85% ~ 98%, and rutile-type accounts for 2 ~ 15%) of 50nm, this has higher photocatalytic activity than pure nanometer anatase titania.
2, add nano zine oxide and can further increase its photocatalysis antibacterial performance.
3, add binding agent and dispersant and can guarantee the coating difficult drop-off, can wash, do not influence its flexibility simultaneously.
4, adopt to brush under the vacuum filtration and can guarantee that mouth mask has certain hole, and keep gas permeability preferably, allow coating suitably immerse the mouth mask nexine simultaneously, reduce the size of hole, improve rejection rate.
5, coating layer thickness, pore size all can be controlled according to the brushing number of times.
The present invention can reach following technical indicator:
1, Quinn experimental technique and the GB15979-1995 according to health ministry " disinfection technology standard-bacteriostatic experiment " detects: the sterilization rate of Escherichia coli, gold-coloured staphylococci, bacillus subtilis all reaches more than 99%.
2, detect according to health ministry " disinfection technology standard-skin irritation test ", the skin nonirritant.
3, detect true border innocuous substance according to health ministry " disinfection technology standard-acute oral toxicity experiment ".
Four, the specific embodiment
(1) gets the following unformed titanium dioxide of 50nm that the precipitation method or sol method prepare, obtain mixed crystal type nanometer titanium dioxide after 1～2 hour in calcining under 600～800 ℃; (2) press that mass ratio obtains homodisperse colloidal sol with 0.5～30 part of particle diameter after less than the mixed crystal type nanometer titanium dioxide (wherein anatase titanium dioxide 85%～98%, rutile titanium dioxide 2%～15%) of 50nm, 0.5～10 part of nano-ZnO, 0.5～5 part of dispersant, 0.5～15 part of binding agent and 40～90 parts of distilled water high-speed stirred or suspension is standby; (3) get health gauze mask commonly used, put into vacuumfilter one by one and spread out and pave, with writing brush and soft little Mao with the colloidal sol brushing on mouth mask, carry out vacuum filtration simultaneously; (4) promptly obtain the antimicrobial form medical protective mask behind the mouth mask airing after will brushing evenly.
