Description
Technical field
The present invention relates to medical material tech field, particularly relate to a kind of medical variable color sterilization coating and its preparation method.
Background technology
Fungicidal Latex Coatings is possible to prevent the coating of mould-growth. It is based on emulsion paint, lacquer, ethenoid resin paint, oil paint. in the normal temperature dry property coating of urea formaldehyde coating, phthalic resin coating etc., add a small amount of disinfectant or can mould fungus inhibition growth anti---the coating that agent coordinates and becomes. After paint solidification film forming; mould inhibitor can slowly be exuded to film and prevent mould generation for a long time; thus protect coated article once not used oleic acid phenyl not wait organic mercury salt to make mould inhibitor by mould erosion, because the nontoxic or hypotoxicity mould inhibitor adopted before the inactive mouth of the harmful drought of Liu Renti mainly contains; Two two J mono-base stannic oxide, two fourths compile the organo-tin compounds such as two lauric acid tin, tributyl-tin fumarate, tributyltin chloride, the organocopper compounds such as copper naphthenate, pentachlorophenol copper .H-base beautiful jade copper. tetrachloro isophthalonitrile, to organochlorine compounds such as chlorine Resorcinos, two, two, four, pentachlorophenol, the adjacent benzene China phenolic compound such as phenol, sodium pentachlorophenate, the inorganic salts such as based compound barium metaborate, hydrochloric acid, copper sulfate, Sodium Fluoride, red lead. This type of coating is mainly used in the building wall of fermentation factory, food factory, hospital, humid area, or for communication device, computer, electric equipment products etc.
Coating, is called paint in Chinese tradition name. So-called coating is coated in protected or decorated body surface; and the continuous film of firm attachment can be formed with coated article, normally based on resin or oil or emulsion, add or do not add pigment, filler; add corresponding additive, with the thick liquid that organic solvent or water are formulated. China's more authoritative " coating process " of coating circle one book is definition like this: " coating is a kind of material, and this kind of material can be coated in article surface by different construction technologies, forms adhere well, has certain intensity, continuous print solid film. The film common name film formed like this, also known as paint film or coating. "
Coating (paint), our usual said paint is one wherein. Refer to coat body surface to form film under certain conditions and play protection, the class I liquid I of decoration or other specific functions (insulation, antirust, mildew-resistant, heat-resisting etc.) or solid material. It is main raw material mainly with vegetables oil greatly because of early stage coating, therefore also known as painting. Present synthetic resins instead of vegetables oil, therefore is called coating. Coating non-liquid, powder coating is the big class of coating variety one.
Coating belongs to organic chemical industry's macromolecular material, and the film formed belongs to macromolecular compound type.According to the classification of the Chemicals that the modern times pass through, coating belongs to fine chemical product. Modern coating is progressively becoming the engineering materials of a class multifunctionality, is the important industry of in chemical industry.
Effect mainly contains 4 points: protection, decoration, covers up defect and other special roles of product, the value of improving product. Founding of New, over 60 years, with the development of national economy every profession and trade, progressively develops into the essential important industry in each field of national economy as its supporting coatings industry from an extremely unobtrusive little industry. Through the struggling hard of several generations, pioneering and keeping forging ahead, China has become second-biggest-in-the-world coating material production state and consumption state, enters into the main flow of world's coating industry development.
Some compound of photochromic finger molecular structure under the light action of certain wavelength and intensity can change, thus causes it to the corresponding change of the absorption peak of light and color, and this kind of change is generally reversible. The mankind find the photochromism history of existing more than 100 year. First successful commercial applications starts from the sixties in 20th century, first two materialogy man Amistead and Stooky of the Corning working spaces of the U.S. have found the ability of reverse photochromism performance [4] containing silver halide (AgX) glass, and people to its mechanism and should be used as big quantity research and develop light-sensitive sunglasses subsequently. But the processing technology of the cost higher due to it and complexity, is unsuitable for making big area photochromic glass, limits its commercial applications at building field. Hereafter the photochromic using gravity-center of AgX has turned to that price is cheap and the polymer-based material of lighter weight, and the performance of various novel photochromic material and application thereof also start systematic study.
Photochromic pigment is added in transparent resin, makes phototropic material, it is possible to for sunglass lens, domestic in light-sensitive sunglasses started application. Photochromic pigment and superpolymer are linked together, it is possible to make the material with phototropic performance, very promising in photoelectric technology and light-operated device. Various daily necessities, clothes, toy, ornament, perambulator can be made into the coating of photochromic material or be applied in inner-outer wall, the various signs of highway label and buildings etc., pattern, can present that color is abundant under light illumination, gorgeous pattern or decorative pattern, beautify life and the environment of people; Can making transparent plastic film, be attached to or embed on vehicle glass or window glass, sun exposure variable color at once, makes daylight not dazzling, and protection eyesight, ensures safety, and can play the interior effect with vapour vehicle interior temperature of surge chamber; Can also molten people or be mixed in plastics film, as agricultural greenhouse plastic sheeting for farm use, increase the output of agricultural-food, veterinary antibiotics etc. Another important purposes is the hidden material being used as in military affairs, the outer cover etc. of the clothes of such as military personnel and fight weapon.
