Abstract
Originally it is new to disclose a kind of film with antibacterial functions, including antibacterial resin coating (1), colored printing ink layer (2), substrate layer (3), bottom coating resin layer (4), adhesive layer (5), described antibacterial resin coating is to prepare to turn into coating solution after uniformly having mixed with polyurethane transparent resin by having loaded the inorganic ion exchanger of fine silver particle；One layer of coating with antibacterial effect is manufactured in substrate surface by coating and/or typography again.This novel product has antibacterial, decoration, antiforge function.
Description
Technical field
Originally it is new to be related to a kind of functional membrane, more particularly to a kind of functional membrane with broad spectrum activity antibacterial functions.
Background technology
Because the propagation of infectious disease generally goes through bacterium, viral contagion, the new variation especially occurred in recent years
Germ, and in the market functional membrane causes indirect contact transmission sometimes just into the carrier for propagating germ virus.
Indirect contact transmission is also known as Rountine contiguity spread, refers to that susceptible person contacts the excreta in infected source or divided
Secretion pollution daily living article and caused by propagation.Contaminated hand plays especially important work in indirect contact transmission
With.For example, the food contacted by the hand contamination of enteric infection patient can orally propagate dysentery, typhoid fever, cholera, A type liver
It is scorching；Contaminated clothes, bed clothes, cap can propagate scabies, tinea etc.；Toy for children, tableware, stationery can propagate diphtheria, scarlet fever；
Trachoma, acute hemorrhagic conjunctivitis can be propagated with contaminated towel by washing one's face；Closet can propagate dysentery, trichomoniasis；The skin of animal
Hair can propagate anthrax, brucellosis etc..
Infectious disease caused by indirect contact transmission, case are in distribute, can also form family or same indoor propagation more.In order to
Indirect contact transmission is reduced, market needs a kind of broad-spectrum antimicrobial effect film, and broad-spectrum antimicrobial effect functional membrane still belongs to market sky
In vain.

Sequentially to increase and decrease thickness.
This new beneficial effect
1st, preparing antiseptic particulate turns into antibacterial resin (ink) and corresponding antibacterial film printed/coated technique, especially
It is that transparent or matt and multicolour pattern are made a plate and printed by computer software design, is printed in above-mentioned substrate surface and produce antibacterial
The film and its compound working procedure pre-coating film of effect, it is the functional package product with antibacterial effect, therefore this new product
With antibacterial, decoration, antiforge function.This new antiseptic technology for belonging to type safe to the human body answering in package decoration industry
With.
2nd, the combination process of antibacterial base material, composite demand antibacterial resin coating high temperature resistant is extruded except corresponding；It can also use
Dry type is compound or wet type is compound, and corresponding dry type is compound, it is desirable to antibacterial resin coating rub resistance；Corresponding wet type combination process requirement is anti-
Bacterium resinous coat is water-fast.Antibacterial resin coating has the advantages of rub resistance, water-fast, is a kind of safety for integrating multinomial technical matters
Type antimicrobial packaging decorative product.
3rd, this new product can use the conducts such as film or paper, woven cloth such as BOPP, BOPET, BOPA, CPP, PE
Base material is processed into antibiotic property package decoration pre-coating film.
4th, new this product needs to be configured to metal fine silver particle and polyurethane for the transparent resin of representative to be adapted to coating
Technical matters.The particulate of argent is uniformly dissolved in transparent resin,
The outside parcel basic zirconium phosphate of metal silver particles, its diameter are placed into ethanol equal solvent and stirred in 1 μ -2m
And turn into antibacterial mother liquor.Key problem in technology is after first using radial pump and the stirring of axial pump synchronization pump, to form antibacterial mother liquor；The
Two make dissolving order be that particulate will be poured into continuously in solvent on a small quantity, necessarily can not be anti-, otherwise form suspension and cause to scrap；The
Three, needed when antiseptic solution is coated between viscosity is adjusted to 13-24 seconds and (examine the detection of grace 3# cups).
5th, the coating of the hybrid resin containing metal silver particles turns into the consistent effect of appearance uniform, it is necessary to print and be coated with
The correspondence of mask-making technology, that is, need by silver particles and its wrapped resin insertion intaglio plate ink cell among, be completely transferred to printing base
Corresponding technique on material.It is the two of technological difficulties.
The ink cell design parameter of printing machine is 20-30 μm of ink cell width, and net is deep 30-60 μm.This is new to contain argent
And its diameter of parcel particulate is much smaller than the geometric volume of ink cell, configured by argent and its parcel particulate and transparent resin
Coating fluid, it is possible to achieve the function of intaglio printing, realize that silver particles and its wrapped resin are embedded among the ink cell of intaglio plate, Mei Gekong
Multiple enwrapped granules are had in cave；By intaglio plate and scraper and printing code, the corresponding work that will be completely transferred on printed substrate
The hybrid resin of skill
6th, this new preparation method, embodies organic the linking of pre-coating film and antibacterial base material production process, tens of micro-
The rugged metal silver particles of meter level, which are printed or are coated with substrate surface, turns into salient point, and guarantee has uniform matt outward appearance to imitate
Fruit and effective adhesive effect and peel strength.And using computer software design plate-making and using antibacterial resin as antibacterial oil
Ink, it is transparent with the pattern printing of matt effect and color printing to carry out surface.The processing mode of antibacterial film backing layer adhesive, use
That gluing and the complex technique of a variety of special processes is used as post-processing process, be the industry and occasion applied according to antibacterial film and
It is fixed, but high temperature resistant is respectively provided with, surface ensures the advantages of non-discolouring.
7th, antibacterial resin coating is argent and phosphoric acid particulate zirconia and polyurethane resin.This is to be different from other antibacterial products
A maximum advantage, as long as not edible i.e. safety.Therefore, women and children's articles for use, stationery, dress ornament, furniture decoration, luxurious be can be applied to
On the overlay films and packaging of multiple product such as wasteful product packaging, the use that can trust.
8th, this new described antibacterial film has the broad spectrum activity of antibacterial, Escherichia coli, colon bacillus 0157, golden yellow grape ball
Bacterium, aspergillus niger bacterium, green pus bacterium, withered grass bacterium, candida albicans, bud branch mould, MRSA are effective.
