Description
Technical field
The present invention relates to a kind of coating and preparation method thereof with long-acting bactericidal function.
Background technology
Along with science and technology development, various modern buildings be presented in people in face of, like glass body of wall, metallic object packing etc.Have at present many novel buildings to adopt the building of Roof system, the especially steelwork of metal construction again, its Roof system also adopts the Roof system of metal construction naturally.The composite metal Roof system is used more and more widely in buildingss such as all types of industries, physical culture, amusement, exhibition center, retail supermarket.Metal Roof system need be used metal roofing board and metal construction base plate.In addition, in various building systems, also generally use the metal wall panel at present.The coated metallic plate that is used for metope or roofing enclosure comprises above-mentioned metal roofing board, metal construction base plate and metal wall panel, can be referred to as metal enclosing guard plate.
Metal current wall interior panel and top ceiling have wide range of applications, and it has advantages such as durable, attractive in appearance.But along with the growth of duration of service, its outside surface can be stained with objectionable impuritiess such as impurity such as dust granules and breed bacteria and but be difficult for discovering; And, clean utmost point trouble because the general suspension of metal enclosing guard plate and top ceiling is higher, therefore existing metal enclosing guard plate seldom carries out cleaned at regular intervals; Along with the growth of duration of service, get confused easily, shade in the surface of metal enclosing guard plate, influences the aesthetics of product.The applicant once was used for Nano titanium dioxide the coating of metal enclosing guard plate and top ceiling; Preferably resolve the self-cleaning problem and the sterilization problem of metal enclosing guard plate and top ceiling; But must the germ-resistant photocatalyst effect of competence exertion when visible light or UV-light are arranged owing to wherein play the titanium oxide of germicidal action; Therefore in period and occasions such as night, cloudy daies, can not bring into play germ-resistant effect fully.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art; A kind of coating with long-acting bactericidal function that the light time also can bactericidal purifying that do not have is provided; Adopt this coating can directly apply on metal enclosing guard plate, top ceiling and the various base material material environmental protection, health, convenience for washing, attractive and durable.
In addition, the present invention also provides a kind of this to have the preparation method of the coating of long-acting bactericidal function.
The technical scheme that coating adopted that the present invention has the long-acting bactericidal function is: the coating that the present invention has the long-acting bactericidal function comprises following components in weight percentage: nanometer zinc 5～20%; Nano titanium dioxide 1～10%; Resin 5～20%, all the other are water.
Said coating with long-acting bactericidal function comprises that also weight percent is 0～1% nanometer silver.
Perhaps, said coating with long-acting bactericidal function comprises that also weight percent is 0～1% nanometer copper.
Said nanometer zinc is Nano-class zinc oxide.
Said pH value with coating of long-acting bactericidal function is 1～2.
The technical scheme that the preparation method adopted that the present invention has the coating of long-acting bactericidal function is: may further comprise the steps:
(1) with nanometer zinc, Nano titanium dioxide, the resin and water mixing stirring of said weight proportion;
(2) above-mentioned slurry is heated and continue to stir under 40～80 ℃, the control pH value of slurry is 1～2 in heating and the whipping process;
(3) detect, pack.
Further, in said step (1), also adding weight percent is 0～1% nanometer silver.
Perhaps, in said step (1), also adding weight percent is 0～1% nanometer copper.
Said nanometer zinc is Nano-class zinc oxide.
The invention has the beneficial effects as follows: comprise nanometer zinc 5～20% because the present invention has the coating of long-acting bactericidal function, Nano titanium dioxide 1～10%, titanium oxide are as photocatalyst, through certain light source irradiation; Can promote most organic cpds generation oxidizing reactions, the oxidation step of going forward side by side generates CO2 and H2O, and it acts on wide spectrum, in the photocatalyst reaction process; Can not only destroy biotic factor, also can destroy various organic chemicalss, promote the carrying out of chemical reaction; Harmful organic gas is had certain oxygenolysis, therefore have purifying air, environment is antibiotic and the de-odorised function, has changed traditional environmental purification technology mode; Titanium oxide tool strongly hydrophilic so the surface has self-cleaning function, keeps bright and clean forever in addition; Clean conveniently, prevent that dirt from adhering to, in the photocatalyst reaction process, titanium oxide is not participated in reaction and is not discharged objectionable impurities in addition; Only play the catalysis instrumentality, itself do not prolong in time and consume, self property is constant before and after the reaction; In reaction process, the material that is acted on is completely oxidized to innoxious substances such as harmless carbonic acid gas and water, therefore harmless fully to environment, help HUMAN HEALTH; And work-ing life is lasting, is suitable for the lifelong of metal enclosing guard plate and effectively uses, and it can play a role containing under the multiple light sources such as faint ultraviolet light, natural light, sunlight; Nanometer zinc is called nano zine oxide again; In concentration is that the sterilizing rate of 5min streptococcus aureus in 1% the nanometer zinc suspension liquid is 98.86%, and colibacillary sterilizing rate is 99.93%, there are some researches show: nanometer zinc also has the effect that divides toxolysin simultaneously germ-resistant; Consumption is little and significantly efficient; Therefore it has anti-microbial effect, and the anti-microbial effect of nanometer zinc do not rely on light, therefore adopts Nano titanium dioxide and nanometer zinc to be applied in the coating as antimicrobial component; Can realize round-the-clock germicidal action in that antibiotic and sterilizing under light and the unglazed situation is arranged; So coating of the present invention is not having the light time can bactericidal purifying yet, has the long-acting bactericidal function, adopts this coating can directly apply on metal enclosing guard plate, top ceiling and the various base material material environmental protection, health, convenience for washing, attractive and durable.
