Abstract
The invention relates to PE/PTFE wax micro powder loaded with nano-silver. Coating or printing ink added with the PE/PTFE wax micro powder loaded with the nano-silver has a good antibacterial property, abrasive resistance and stain resistance, and meanwhile has good hand feeling.
Description
Technical field
The present invention relates to a kind of PE/PTFE wax micro mist of loading nano silvery, relate in particular to a kind of PE/PTFE wax micro mist being added on the loading nano silvery used in coating or ink.
Background technology
Wax micro mist, the superfine powder of a kind of median size 2-15 μm, is added in coating or ink by as a kind of auxiliary agent usually, plays the effects such as rub resistance, stain resistant, delustring, degassed and excellent handle.
Nanometer silver, the metallics of a kind of particle diameter only 2-4nm, because its silver ions has the function of kill bacteria and mould, is usually used as disinfectant.But, nanometer silver due to the feature of itself, in coating and ink time maximum difficulty be exactly its dispersion, the reunion because of particle falls sharply by its effect.
Main points of the present invention are exactly by the Argent grain load of Nano Particle on the wax powder of micron-level particle size, and when wax micro mist adds in coating and ink, silver is just subsidiary on the particle of wax micro mist.
Wax micro mist is not a kind of simple filling in coating.Dispersed wax micro mist is in the coating in coating curing process, and due to it and coated substrate resin compatible sex differernce, wax micro powder granule can be separated out and is enriched in top layer.This reduces silver particles buried in the probability of coat inside, larger sterilising effect can be reached with the silver of smaller amounts.Coating crocking resistance is significantly improved in the interpolation of wax micro mist thus the probability that silver ions is lost in life-time service process reduces, and keeps its effect within the longer time.The interpolation of wax micro mist will reduce the water absorbability of coating and improve its contamination resistance, be unfavorable for the existence of bacterium and mould, and nanometer silver have effect of superposition.
The wax micro mist of loading nano silvery is specially adapted to coating and the ink of following purposes:
The currency often contacted with hand and paper money issued by a provincial bank to be circulated in a given area
The normal household electrical appliance, mobile phone, notebook etc. contacted with hand
Need books and the document of long-term preservation
Leather clothing, handbag, ornament
Conventional utensil, handle, switch, cigarette package etc.
Summary of the invention
The object of the invention is the restriction breaking through wax micro mist self material, provide a kind of and there is good germ resistance, wear resistance, contamination resistance, also have the PE/PTFE wax micro mist of the loading nano silvery of good feel simultaneously.
A PE/PTFE wax micro mist for loading nano silvery, it comprises PE wax, PTFE wax, nanometer silver.Wherein PE wax, PTFE wax are body material.
The weight percent of each component is as follows:
PE wax 30%-90%, preferred 50%-70%
PTFE wax 10%-50%, preferred 15%-30%
Nanometer silver dispersion 1%-5%, wherein effectively content of nanometer silver is not less than 5%
The preparation of nanometer silver dispersion does not belong to this technology category, can adopt commercial commodity, can prepare voluntarily yet, but should meet following condition:
1, no matter nanometer silver dispersion is solid-state powder or the dispersion liquid of liquid state, and wherein effectively content of nanometer silver can not lower than 5%, if should by the consumption of effective content of nanometer silver conversion nanometer silver dispersion lower than 5%
2, the particle diameter of single nano-Ag particles should below 6 nanometers, and independent dispersion is in dispersion, and two and two or more particle be that the ratio of state of aggregation existence should not be greater than 20%.
It is the highest that contriver finds to adopt the PE/PTFE wax micro mist cost performance of the loading nano silvery prepared by aforementioned proportion.
Embodiment
The PE/PTFE wax micro mist of loading nano silvery of the present invention is set forth further below in conjunction with embodiment.
Embodiment 1
A PE/PTFE wax micro mist for loading nano silvery, takes each feed composition according to following weight proportioning: PE wax 75%, PTFE wax 22.5%, nanometer silver dispersion 2.5% containing effective nanometer silver 6%.
The production technique of the PE/PTFE wax micro mist of this loading nano silvery, concrete steps are as follows:
1, PE wax, PTFE wax, nanometer silver dispersion is accurately taken in reactor, heating and melting;
2, after abundant melting, through duct type shredder circular grinding, make nanometer silver dispersed by mechanize educational level and be attached on wax body;
3, also fine grinding is cooled rapidly.
The PE/PTFE wax micro mist of the loading nano silvery of the present invention obtained by above-mentioned steps is a kind of white fine powder, median size D
v50=4-5 μm, maximum particle diameter D
vMAX=8-9 μm.
Embodiment 2
1, be directly added in coating in 1.5% ratio by the PE/PTFE wax micro mist of the loading nano silvery obtained by embodiment 1, rotating speed is 700-800rpm, stirs 30 minutes, and in coating, total effectively content of nanometer silver is 20ppm;
2, previous step gained coating color development wheel is coated on paperboard, polyester film sheet respectively, dry 24 hours;
3, make antibacterial tests respectively with intestinal bacteria and streptococcus aureus, experimental result shows obvious germ resistance, and sterilization rate is not less than 80%;
4, on abrasion tester, detect wear resistance, result shows, and rub resistance number of times is more than 1000 times, and the contrast sample abrasion resistance of not adding wax powder is no more than 100 times;
5, film coated surface and water contact angle are 116 °, comparatively contrast the more hydrophobic and stain resistant of 111 °, sample;
6, film coated surface has good feel.
