Abstract
The invention discloses a silver-containing antibacterial agent and a preparation method thereof; the antibacterial agent is prepared by coating silver on stone powder surfaces, and mainly comprises 99-99.999 parts by weight of stone powder, and 0.001-1 parts by weight of silver, wherein the stone powder is powder that comprises the main component is calcium carbonate and also comprises a certain ratio of silicate, and the powder is obtained by pulverizing natural stone ore materials and has a mesh number of 100-10000; the silver is silver metal particles obtained by deposing silver ions on stone powder surfaces through chemical reduction. With the above scheme, the silver-containing antibacterial agent of the invention adopts stone powder which is commonly used as a filler in plastic products as a substrate, and allows the substrate to load a few silver components; because of a high using amount, the silver-containing antibacterial agent has high homogeneity in products, has low price, and has the characteristics of environmental protection. The silver-containing antibacterial agent of the invention has very good application advantages in plastic industry.
Description
Technical field
The present invention relates to antibacterial agent field, specifically a kind of silver-containing antibacterial agent and preparation method thereof.
Background technology
Along with growth in the living standard, the understanding of people to living environment and require improving constantly, particularly to healthy consciousness also in continuous enhancing.Noxious bacteria is very extensive in distributed in nature, and of a great variety, and quantity is huge, and the mankind's health in serious threat.By spread of germs, infected the disease producing, formed a great society problem, cause extensive concern.Thus, scientific research personnel is devoted to research and develop various antibacterial agents and anti-biotic material, prevents the propagation of bacterium, reduces the infection of bacterium, improves quality of the life.
Antibacterial agent mainly divides organic and inorganic two large classes.Organic antibacterial agent is synthetic type organic, and the feature of such antibacterial agent is that initial sterilizing power is strong, restraining and sterilizing bacteria successful, but poor heat resistance, and generally, in 200 ℃, long-term use has outflow and separates out phenomenon, easily decomposes, and antibacterial range is narrow.Inorganic antiseptic generally, take metal ions such as silver, zinc, copper as antibacterial agent, take porous, inorganic nonmetallic materials as carrier, is made anti-biotic material.The bactericidal potency of such antibacterial agent is strong, and persistence is good.
Silver ion is that in several metal ion species, effect is best, and to human body, the side effect of environment is little, but cost is higher.At present, in order to reduce costs, improve effect, people are by selecting different carriers as bentonite, active carbon, silica gel, nano titanium oxide etc., the one, utilize the specific surface area of its super large, the 2nd, utilize the clad structure of its porous, to realize silver-colored load, increase silver-colored releasing effect.As CN1308231C, invention utilizes active carbon appendix Nano Silver; CN100432157C invention utilizes kaolin appendix silver, and silver particles is switched in inorganic interlayer; 200810018312.X application utilizes nano attapulgite clay to carry out appendix to silver; 200810031600.9 applicant utilizes nano titanium oxide to carry out appendix to silver.
The target of all kinds of inventions is all the structures from carrier material above, or the carrier of finding is cellular structure material, or is ultra-fine nanometer grade powder, to increase the specific surface area of carrier; The anti-biotic material of preparing by this class technology generally can obtain the appendix silver that content is higher, and therefore, its product cost is also high.During application, can, by the form of additive, add in target product on a small quantity, as add plastic substrate to.Such antibacterial agent exists a larger problem to be exactly in the interpolation modification application of plastics or rubber etc.: its silver-colored content of antibacterial agent of general design is higher, conventionally reach the needed silver content of antibacterial effect very low, therefore, in actual use, often need the antibacterial powder of minute quantity to add in a large amount of objects, this certainly will need to consider the scattering problem of adding procedure, to avoid causing local concentration higher, and the antibacterial component content on other ground is too low, maybe need to realize by processes such as diffusions.In theory, designed antibacterial agent silver content is higher, and the inhomogeneity of its antibacterial composition that may cause is larger, affects the antibacterial effect of product.
Summary of the invention
The object of this invention is to provide a kind of in goods the higher silver-containing antibacterial agent of antibacterial composition homogeneity.
Another object of the present invention is to provide a kind of method of preparing above-mentioned silver-containing antibacterial agent.
To achieve these goals, the present invention adopts following technical scheme:
A kind of silver-containing antibacterial agent, is coated on stone flour surface by silver and forms, and mainly contains following parts by weight of component:
Stone flour 99-99.999 part
Silver 0.001-1 part
Wherein, described stone flour, refers to that the Main Ingredients and Appearance obtaining by pulverizing natural stone pit wood material is calcium carbonate the powder that contains a certain proportion of silicate, and order number is 100-10000 order; Described silver, refers to that silver ion is deposited on the silver metal particle on described stone flour surface by electronation.
A kind of silver-containing antibacterial agent, its preparation method is as follows: by 100 weight portion order numbers, be that 100-10000 order Main Ingredients and Appearance is that calcium carbonate the stone flour that contains a certain proportion of silicate are scattered in distilled water, add again the liquor argenti nitratis ophthalmicus that hundred parts of specific concentrations of 1-8 weight portion quality are 0.16-20%, stir, drip again the sodium borohydride solution that hundred parts of specific concentrations of 1-8 weight portion quality are 0.2-20%, to mixed liquor, be green; Standing, by mixed liquor suction filtration, washing, puts at 120-300 ℃ and dries, and just obtains the silver-containing antibacterial agent of powder shaped.
The consumption of above-mentioned distilled water is 100-500 weight portion.
Adopt after such scheme, silver-containing antibacterial agent of the present invention, has following characteristics and advantages:
First, it is to adopt plastic cement industry to be widely used packing material--stone flour is matrix, the silver-colored composition that appendix is a small amount of.Due to stone flour, (Main Ingredients and Appearance is calcium carbonate, and contain a certain proportion of silicate etc.) be the filler generally using in plastic cement products, conventionally consequently honest and clean is adding purpose, also the combination property of product is had to certain modified effect, addition is large, generally exceed 10wt%, in many occasions, exceed 50wt%; Appropriate silver-colored composition on the specific surface appendix of stone flour, makes stone flour have antibiotic property, and when it is filled in plastic substrate in a large number, because usage amount is high, the even property of its distribution in goods various piece is higher.
Its two, the conventional filler that stone flour is plastic cement, general plastic cement tradesman is clearer to its character, the technological process of the complex plastic of processing, processing and use procedure, without increase and decrease operation; In addition, the modification of tradesman to stone flour and being familiar with the character of the compatibility of resin, easy to use.
Its three, stone flour is mostly mine elaboration products, or the accessory substance of granite sheet material processing, and it is carried out to antimicrobial treatment, improves application grade, not only cheap, also has environmental protection feature.
Therefore, silver-containing antibacterial powder of the present invention will have good application advantage in plastic cement industry.
