Abstract
A paint for internal wall of building is prepared through mixing active zeolite with one or more antibacterial metals in water at 60-80 deg.C for ion exchanging, baking, grinding, and mixing with ordinary paint for internal wall. Its advantages are high antibacterial effect, quick effect and durable release.
Description
The present invention relates to coating, especially speciality coating is made the field.
At present, dope for inner wall of architecture on the market is made up of acrylic resin thinner, dispersion agent, filler, brightening agent etc.Owing to do not add antiseptic-germicide, when conditions being possesseds such as temperature, humidity, coating surface will produce a large amount of harmful bacterium, moulds that get, and especially in the corner in house, water drain etc. are located, and are all the more so.In hospital, due to illness the people touches wall, door handle etc. and locates, and bacterium, germ breed at coating surface, also can increase the infection of disease, health risk.
The objective of the invention is to explore a kind of preparation method of antibiotic paint, make under the simple relatively situation of production method, produce the antibiotic paint product with lower production cost.
The present invention also aims to avoid above-mentioned the deficiencies in the prior art, a kind of antibiotic paint that provides makes it have long lasting antibacterial.
The objective of the invention is to realize by following means.
The production method of inner wall of building antibiotic paint, adopt following step to produce product:
1. after will making the powder that median size is the 0.1-10 micron as the zeolite grinding of carrier earlier, heat-activated in baking oven.
2. in 60 ℃-80 ℃ deionized water, add antibacterial metal salts, antibacterial metal salts is: silver, copper, vitriol such as zinc, nitrate, one or more mixing in the acetate, make the reaction solution that concentration is 0.1-0.3M, in reaction solution, add the carrier that 1. step prepares, add-on is to add 0.5-1 kilogram carrier in every liter of reaction solution, keep temperature and continuously stirring, carry out ion-exchange, after reaction is finished, remove supernatant, use the clear water washing precipitate, the ion that removal is adhered to 110 ℃-120 ℃ oven dry down, grinds to form the support powder of median size 0.1-10 micron.
3. the support powder that 2. step is prepared is heated to 300 ℃-500 ℃, and time 3-6 hour, make antibacterial metal ions and zeolite mortise, become inorganic antiseptic.
4. getting antiseptic-germicide 0.5%-10% (weight) that 3. step prepare, to add in the common building interior wall coating thorough mixing even, process method construction routinely, behind the paint solidification, antibiotic dope for inner wall of architecture product.
Making method of the present invention is simple and practical, and after adding a small amount of antiseptic-germicide, common coating is transformed into antibiotic paint.The antiseptic-germicide that adds does not influence the various performances of coating.Behind the paint solidification, inorganic antiseptic performance anti-microbial effect, antibacterial metal ions combines with carrier firmly, dissolved degree of separating is low, and soluble test was not seen obvious silver ions stripping after one month, chemical stability is good, characteristics such as the slow releasing function phase is long, and have long-term germ resistance, broad spectrum antibacterial is preferably arranged.The product cost made from the present invention is low, and is free from environmental pollution, is beneficial to and promotes the use of.
The invention will be further described below in conjunction with embodiment.
The used coating of the present invention is sold product by market, and epoxypaint also is the commercially available prod.
The selected antibacterial metal of the present invention is: Silver Nitrate, zinc nitrate, zinc sulfate, zinc acetate, zinc oxide, copper sulfate, neutralized verdigris etc.In coating, one or more above mixtures play a role jointly.Antibacterial metal is preferably: Silver Nitrate.Above raw material is product that market is purchased.
The selected antiseptic-germicide of the present invention is: zeolite, titanium oxide, zinc oxide, glass, pottery, phosphatic rock etc., preferably zeolite.
Embodiment one
Get 13X type permutite 2000 gram and grind that to make median size be that 0.1 micron powder is put in the enamel tray, temperature is controlled at 150 ℃, dries by the fire 4 hours, activates, make its moisture be lower than 1% standby.
Get 200 gram Silver Nitrates, be dissolved in 3 liters of deionized waters, 13X zeolite after the activation is slowly joined in the silver nitrate solution of 60 ℃ of perseverances, immersion and continuously stirring 8 hours, carry out ion-exchange, the sodium ion in antibacterial metal silver ions and the zeolite is replaced, antibacterial metal ions enters in the zeolite net shelf structure, make it become the inorganic antiseptic with antibacterial, antibacterial zeolite particles.After precipitation is removed supernatant, remove free ions with clear water, 120 ℃ of oven dry were down calcined 4 hours down at 350 ℃ after grinding in baking oven, and the taking-up back is standby.Get common building interior wall coating (Shanghai " Shen is true ") 200 grams of buying in market, antiseptic-germicide is added in the coating in the ratio of 5% (weight), on high-speed grinder, rotating speed with 200 rev/mins, ground 5 minutes, and made its abundant mixing, coating application method construction routinely after the taking-up.
Embodiment two
Antiseptic-germicide carrier 200 gram is Silver Nitrate: the mixture of zinc nitrate (1: 7), grinding and making median size is 10 microns powder, makes inorganic antiseptic by embodiment one identical method.Ratio in 10% (weight) is added in the epoxy-based coatings.On high-speed grinder, with 200 rev/mins rotating speed, ground 5 minutes, make its abundant mixing, constructional method construction routinely after the taking-up.
With the antibiotic paint that this law is made, antibacterial effect is fast, lasting, and the result is as follows after tested:
(1) intestinal bacteria 8099 are adopted in the test strain.
(2) test strain adopts streptococcus aureus ATCC6538.
(3) test materials: MH meat soup nutrient agar medium, physiological saline is issued " disinfection technology standard " configuration by health ministry.
(4) test method:
With the 50 * 50mm sheet glass that scribbles antibiotic paint that embodiment one and embodiment two make respectively, under High Temperature High Pressure, sterilized 20 minutes, thoroughly body is killed assorted bacterium, and 8099 and 6538 standard bacterial concentrations (are equivalent to 1.2 * 10
6CFU/ml bacterium liquid) 0.5ml drips on the slide that scribbles antibiotic paint, and bacterium liquid is contacted with specimen surface, in 37 ℃ of incubators, cultivated 24 hours, and live bacterial count, control group carries out live bacterial count with common coating with above-mentioned method, measures its antibiotic rate.
(5) antibacterial tests result
