Its advantages are high dispersity and uniformity, high efficiency and effect, and low cost.
Description
Technical field:
The present invention relates to a kind of additive that is used for coating, plastics and yarn fabric, particularly a kind of nano level manufacture method with composite granule of antibacterial deodouring function.
Background technology:
In the prior art, be applied to coating as functional additive, the existing extensively report of the nanometer grade powder material of plastics and field of textiles, as antimicrobial powder, antistatic powder, uvioresistant powder and anion powder etc., in its preparation process, no matter adopt chemical process or physical method, the nano material that all at first prepares single material, handle through special modification again, use as functional additive then, its insufficient aspect is, function singleness, even if the cost height is compound nano material, it also is the nano material for preparing single material earlier, and then mix, antimicrobial powder major part wherein is an organic chemicals, all the other are silver, the antiseptic-germicide of cupric ion series.
Summary of the invention:
Technical problem to be solved by this invention is: the nano material function singleness of using as functional additive in the prior art, at first need to prepare the nano material of single material, the cost height, bad dispersibility, agglomeration is serious, and antimicrobial powder major part wherein is an organic chemicals, in the use, can bring toxic side effect.The present invention for the technical scheme that above-mentioned technical problem adopted that solves in the prior art is, a kind of manufacture method of nano-class antibacterial deodouring composite powder is provided, the manufacture method of described this nano-class antibacterial deodouring composite powder comprises the step of mixing of materials and super-fine processing, wherein, at first carry out the step of mixing of materials, next carries out the step of super-fine processing, particularly, the step of described mixing of materials comprises the step that material is handled by proportioning metering, mixing and modification, and wherein the preferred feed that is adopted is micron-sized inorganic oxide and natural ore powder; The step of described super-fine processing is in order: preparation aqueous suspension, one-level stir mill, secondary stirs mill, separates drying, classification depolymerization, detection, acquisition superfine powder, further, in the process of described preparation aqueous suspension, can also add tensio-active agent, in the process of described classification depolymerization, can also add dispersion agent, and can also get back to described secondary stirring mill through the material of classification depolymerization and handle once more.
The present invention contrasts prior art, owing to adopted the first compound processing step of pulverizing again, make that the component of superfine powder is compound evenly, can interpenetrate, fold embedding, good dispersity, the better effects if of anti-agglomeration, favourable and additive and use the compound compatible of base-material, simultaneously, the pulverizing of various materials can concentrate in the step and finish, improve efficient, reduced cost.
Below in conjunction with one of the present invention embodiment that is applied to plastics film (PE casting films), the present invention is further illustrated.
Embodiment:
The manufacture method of a kind of nano-class antibacterial deodouring composite powder of the present invention, the step that comprises mixing of materials and super-fine processing, wherein, at first carry out the step of mixing of materials, next carries out the step of super-fine processing, particularly, the step of described mixing of materials comprises the step that material is handled by proportioning metering, mixing and modification, and wherein the preferred feed that is adopted is micron-sized inorganic oxide and natural ore powder; The step of described super-fine processing is in order: preparation aqueous suspension, one-level stir mill, secondary stirs mill, separates drying, classification depolymerization, detection, acquisition superfine powder, further, in the process of described preparation aqueous suspension, can also add tensio-active agent, in the process of described classification depolymerization, can also add dispersion agent, and can also get back to described secondary stirring mill through the material of classification depolymerization and handle once more.
In one of the present invention embodiment that is applied to plastics film (PE casting films), in the step of mixing of materials of the present invention, at first adopt following prescription to carry out proportioning metering, mixing and modification and handle:
| Name of material | Ratio Wt% | Function |
| Zinc oxide ZnO | 30～50 | Antibiotic |
| The tourmalinite breeze | 30～50 | Negative ion, taste removal |
| Titanium dioxide TiO 2 | 10～20 | Catalysis, antibiotic |
| Zeolite | 5～10 | Absorption, taste removal |
| The white carbon black of gas phase | 2～8 | Strengthen and disperse |
| Aluminium sesquioxide | 3～6 | Activity, absorption |
Wherein, described tourmalinite breeze is NaMg3Al6[Si6O18] and (BO3) 3 (OH, F) 4, described dispersion agent adopts anionic carboxylic acid type copolymerizing agent, and described tensio-active agent adopts sorbitan list grease phosphides (C24H44O6).Behind the material metering in the above-mentioned prescription, add mixing tank in proportion, stirring at low speed mixes, and finishes the step of mixing of materials of the present invention.Secondly, enter the step of super-fine processing of the present invention, be prepared the step of aqueous suspension, the aqueous carrier in the described aqueous suspension is pressed following formulated:
| Name of material | Ratio Wt% | Function |
| Carboxymethyl cellulose | 1～2 | Emulsification, anti-settling |
| Dispersion agent | 0.5～3 | Disperse emulsification |
| Tensio-active agent | 2～5 | Disperse emulsification |
| Water | 90～95 |
Material powder after mixed is added described aqueous carrier, the ratio of material powder and aqueous carrier is 30～40: 60～70, stirring becomes aqueous suspension, stirs mill, secondary stirring mill, separates drying, classification depolymerization, detection through one-level successively then, obtains the additive finished product at last.In described separation exsiccant step, will stir the super-fine processing discharging that mill obtains from secondary, add the clear water dilution with 1: 4 ratio, static depositing more than 8 hours progressively removed the upper strata clear water, carries out press filtration, and separated and collected is perhaps inserted oven drying.
In the embodiment that is applied to plastics film (PE casting films), when using as the complex function additive of antibacterial deodouring, according to additive: the ratio of plastic basis material=1: 3 joins in the plastic basis material, and production obtains the PE plastics film with antibacterial deodouring and fresh-keeping function.In this embodiment that is applied to plastics film (PE casting films), its effect is: the particle diameter of composite Nano superfine powder is less than 0.1 nanometer, powder antibiotic rate (500ppm) is more than or equal to 99.5%, and the ability of taste removal is equivalent to 960 negative ions/second Cm
2, in experiment, two of 20 * 20 centimetres plastics films (additive level 0.4%) are inserted in the refrigerator of 180 liters, after 8 hours, basic free from extraneous odour seals fresh freshwater fish with this plastics film in the refrigerator, place 25 degrees centigrade environment, never degenerated with interior in 8 hours.
