Specific embodiment
Describe the present invention below with reference to each embodiment shown in the drawings, below some for the present invention Better embodiment.
A kind of sheet material, its at least surface is with the Ag-TiO to sterilize2Microgranule.Sheet material adopts plastics in the present invention Material is made, Ag-TiO2Microgranule is arranged on the surface of sheet material by way of coating or overlaying, or Ag-TiO2Microgranule leads to Cross after mixing with plastic material and make sheet material again.With reference to shown in Fig. 1, Fig. 2, it shows respectively the sheet material of two kinds of forms.Fig. 1 In, Ag-TiO2Microgranule 10 is arranged at the upper surface of sheet material 11 prepared by plastic material by way of coating or overlaying, concrete to apply Cover or refer to the step of overlaying subsequently to launch content；Fig. 2 show Ag-TiO2Microgranule 10 is made again after mixing with plastic material Sheet material 11, Ag-TiO2Microgranule 10 is uniformly distributed in the inside of sheet material 11 and surface.
There is Ag-TiO in the present embodiment on involved sheet material2Microgranule, in sheet material application process, the surface of sheet material can be with Release Ag+, Ag+ have anti-microbial property, and its antimicrobial mode can be the cell wall and cell membrane for destroying antibacterial, cause antibacterial content Beyond the region of objective existence is let out, and can be combined with the DNA of antibacterial or RNA, makes DNA of bacteria or RNA lose replication capacity, with the albumen in antibacterial body Matter is combined, and makes protein denaturation lose activity.And Ag-TiO2The essence of microgranule is the TiO of nanometer Ag doping2, its Antibacterial Mechanism with TiO2Antibacterial Mechanism be similar to, but due to the presence of nanometer Ag, make TiO2It is more prone to photoelectron and hole, and Ag- TiO2Hole and photoelectronic life-span are longer, and the photoelectron of generation and hole can adsorb in TiO2The water on surface etc. occurs photochemical Reaction is learned, the free radical particles with strong oxidizing property such as OH are generated, these reactive oxygen free radical are thin by strong oxidation oxidation Endobacillary coenzyme A, destroys the cell wall or cell membrane of antibacterial, changes cell wall or membrane passage, causes interior Tolerant leaks, in addition TiO2The DNA structure of antibacterial can be destroyed, makes electric transmission interruption etc. to play photocatalysis antibacterial work With.
In view of more than, sheet material involved in the present invention is a kind of material with more excellent antibiotic and sterilizing effect, and it is refrigerator Manufacturing industry provides a kind of preferable inner container of icebox making material.
In specific some embodiments, the plastic material that sheet material of the present invention is adopted is for ABS（Acrylonitrile-butadiene-benzene second Alkene plastics）、PS（Polystyrene plastics）Or PE-PS（Polyethylene-polystyrene mixture）, certainly, it can also preferably be adopted Some other can be used for the material of conventional refrigerator inner bag making, concrete numerous to list herein.
Present invention also offers it is a kind of with sterilization inner bag refrigerator, the refrigerator have be provided with store food sterilization in Gallbladder, wherein the inner surface additional of sterilization inner bag has the Ag-TiO for sterilizing2Microgranule.
Specifically, the sterilization inner bag in refrigerator of the present invention is made of using sheet material referred to above, more specifically, sheet In invention, sterilization inner bag is made using plastic material, Ag-TiO2Microgranule is arranged at sterilization inner bag by way of coating or overlaying Inner surface on, or Ag-TiO2Microgranule by mixing with plastic material after make sterilization inner bag again.In some specific embodiments In, the plastic material that the inner bag that sterilizes is adopted is for ABS, PS or PE-PS.
The manufacture method of inner bag present invention also offers refrigerator sterilizes, with reference to shown in Fig. 3, it is comprised the following steps：
S1, preparation nanometer Ag material；
S2, on the basis of nanometer Ag material prepare Ag-TiO2Material；
S3, preparation have Ag-TiO2The sheet material of microgranule；
S4, will be with Ag-TiO2The sheet material of microgranule makes the sterilization inner bag by way of adsorption forming, wherein, in sterilization The inner surface of gallbladder has Ag-TiO2Microgranule.
In specific implementation process of the present invention, step S1 includes：Nanometer Ag colloidal sol is prepared using chemical reduction method, NaBH4 is used Used as reducing agent, Compound-acid is used as protective agent, PEG（Polyethylene Glycol）As reducing agent and stabilizer, through reaction nanometer is generated Ag colloidal sols, i.e. nanometer Ag material.
Step S2 includes：Butyl titanate is dissolved in dehydrated alcohol under room temperature, will obtain mixed liquor be slowly added dropwise to In nanometer Ag colloidal sol, stir 40 minutes at a temperature of being placed in 70 DEG C, then instill acid catalyst, then proceed to be stirred at a temperature of 70 DEG C 4h, finally stirs at normal temperatures the aging two day time, and nanometer Ag-TiO is obtained2Colloidal materials, i.e. Ag-TiO2Material.
In the present invention, the inner bag that sterilizes is made using plastic material, and step S3 includes：Plastic material is passed through into extrusion molding For sheet material, by Ag-TiO before sheet material extrusion molding2Material mixes with plastic material, or by Ag- after plate forming TiO2Material is coated or overlayed in the surface of sheet material one, is formed and is had Ag-TiO2The sheet material of microgranule, the structure of concrete sheet material is referred to Shown in Fig. 1, Fig. 2.
In specific implementation process, if by Ag-TiO before sheet material extrusion molding2Material mixes with plastic material, its Processing technology is relatively simple, but substantial amounts of Ag-TiO2Microgranule is present in inside plate body, and the Ag-TiO of plate surface2Fraction of particle Than relatively limited, so in order to the inner bag that ensures to be sterilized by obtained in sheet material has preferable bactericidal effect, in plate body manufacturing process Need to add substantial amounts of Ag-TiO2Material.
If by Ag-TiO after plate forming2Material is coated or overlayed in the surface of sheet material one, and it is needed in traditional ice Increase Ag-TiO after the production process of case inner liner plates2Material coats or overlays step.Wherein coating step is required Ag- TiO2Material makes flow-like, by coating method by flow-like Ag-TiO2Material is uniformly arranged on plastic plate surface, then enters Row curing molding；And overlay step and require Ag-TiO2Material makes film material, sends an invitation card in heating status and invests sheet material table Face, during implementing, can be in membranaceous Ag-TiO2Material surface applies certain pressure, so that Ag-TiO2In modeling Material plate surface has stronger adhesive force, it is to avoid the membranaceous Ag-TiO during the use of refrigerator2Material comes off.
It should be understood that, although this specification is been described by according to embodiment, but not each embodiment only includes one Individual independent technical scheme, this narrating mode of description is only that for clarity those skilled in the art will should say Bright book as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, forming those skilled in the art can With the other embodiment for understanding.
The a series of detailed description of those listed above is only for the feasibility embodiment of the present invention specifically Bright, they simultaneously are not used to limit the scope of the invention, all equivalent implementations made without departing from skill spirit of the present invention Or change should be included within the scope of the present invention.
