Description
Technical field
The present invention relates to the hot-wind nonwoven cloth materials containing graphene oxide for being applied to disposable adsorption object surface layer, originally
Invention by preparing graphene oxide modified PP fiber, after the modified PP fiber for being loaded with graphene oxide is added to filters out again
PE/PP fiber in, the hot-wind nonwoven cloth material containing graphene oxide is prepared by hot-wind nonwoven cloth preparation process,
The human skin touch-safe of hot-wind nonwoven cloth is promoted by the addition and optimum preparation condition improved procedure of graphene oxide
Performance, the hot-wind nonwoven cloth material skin-friendly containing graphene oxide is good, has antibiotic skin-care healthcare function, allergy, can not have
Effect prevents diaper rash, can be applied to the surface layer of disposable adsorption object.
Background technique
In the modern society that rhythm of life is accelerated, disposable adsorption object becomes the first choice of many young parents, paper diaper
Belong to a kind of disposable absorbent article, using rear easy to change, enormously simplifies the cumbersome situation of infant nursing.In recent years messenger
Consumption idea it is increasingly mature, disposable adsorption object is proposed higher to want in human skin touch-safe aspect of performance
It asks.Neonate diaper dermatitis is the common disease of newborn, and thin tender mainly due to newborn skin, structure will not between epidermis and corium
Close, skin keratin development is not perfect, poor to environmental stimuli resistance, vulnerable to caused by mechanicalness and chemical irritation.It is primary at present
Property absorbing articles urgent need to resolve should be skin contact safety problem.Many paper diaper sucting wet air permeabilities especially antibacterial now
Property it is poor, dress for a long time can make the cuticula of skin surface be easy to be stimulated object abrasion, infiltration, finally make skin damage, hair
Inflammation causes infant and suffers from diaper rash.
Graphene is the two dimension crystalline substance for the only one layer atomic thickness for being stripped out from graphite material, being made of carbon atom
Body has excellent machinery, electricity and heat performance, is that presently found most thin, maximum intensity, electrical and thermal conductivity performance are strongest
A kind of novel nano-material.From that day that graphene is found, it just has become the hot spot and focus of research, in super electricity
Appearance, transparent electrode, sea water desalination, sensor, hydrogen storage, solar battery, catalyst carrier, composite material, biologic bracket material,
The fields such as bio-imaging and drug conveying are widely used.
Graphene has excellent anti-microbial property, and graphene is arranged onto non-woven fabrics, antibacterial nonwoven cloth, phase can be prepared
For traditional inorganic, organic antibacterial agent, graphene without cytotoxicity, will not make skin allergy substantially, be more suitable for and people
Body direct skin contact has human skin touch-safe performance.
Graphene is a kind of physics " antibiotic " of potential not drug resistance, not only can be by bacterial cell membrane
Insertion is cut, and can also destroy cell membrane by the extensive direct extraction to phospholipid molecule on cell membrane to kill
Bacterium.Exactly the unique two-dimensional structure of graphene allows to that superpower phase interaction occurs with the phospholipid molecule on bacterial cell membrane
With being detached from cell membrane so as to cause a large amount of phospholipid molecules and be adsorbed onto the surface of graphene oxide.Graphene can be divided into oxygen again
It is super to its inhibiting rate after graphite alkene (GO) and reduced graphene, stannic oxide/graphene nano suspension and Escherichia coli act on 2 h
90% is crossed, antibiotic property is derived from the destruction to Bacillus coli cells film.Toxicologic study the result shows that, graphene oxide is not only
A kind of novel excellent antibacterial material, and to the cytotoxicity very little that mammalian cell generates.Therefore graphene oxide can
Using as effective novel antibacterial material.
With the continuous expansion of the continuous innovation and application field of nonwoven cloth material production technology, development skin-friendly is good, tool
Have antibiotic skin-care healthcare function, not allergy, can effectively prevent the hot-wind nonwoven cloth material containing graphene oxide of diaper rash at
There is an urgent need to the research topics of expansion for one.
Summary of the invention
The purpose of the present invention is to provide be applied to disposable adsorption object surface layer the hot wind containing graphene oxide without
Woven fabric material promotes the human skin of hot-wind nonwoven cloth by the addition and optimum preparation condition improved procedure of graphene oxide
Touch-safe performance, the hot-wind nonwoven cloth material skin-friendly containing graphene oxide is good, has antibiotic skin-care healthcare function, but
It is quick, it can effectively prevent diaper rash, and can be applied to the surface layer of disposable adsorption object.
The present invention is in order to solve the above problem the technical solution adopted is that a kind of hot-wind nonwoven cloth material, contains graphite oxide
Alkene, the surface layer applied to disposable adsorption object；And the preparation method of hot-wind nonwoven cloth material.
The present invention by preparing the modified PP fiber of graphene oxide, after will be loaded with the modified PP fiber of graphene oxide again
It is added in the PE/PP fiber filtered out, by non-woven fabrics, the hot wind containing graphene oxide is prepared in hot wind preparation process
Nonwoven cloth material keeps hot-wind nonwoven cloth skin-friendly good, has antibiotic skin-care healthcare function, has human skin touch-safe
Can, allergy, not can effectively prevent diaper rash, the advance with technology.
The preparation method of the hot-wind nonwoven cloth material containing graphene oxide applied to disposable adsorption object surface layer,
Include:
1) preparation of graphene oxide
Graphene oxide is prepared using Hummers method.
The concentrated sulfuric acid and concentrated phosphoric acid are mixed according to the volume ratio of 1:1~90:1, is placed in ice bath, 1~50 parts by weight is added
Graphite and 1 ~ 30 parts by weight sodium nitrate solid mixture, 5~100 parts by weight are added again, and [remarks parts by weight: summation can be with
100, small formula with gram, big formula with kilogram] (potassium permanganate, stirring, obtains mixed liquor；Then by gained mixed liquor
In 40~70 DEG C magnetic agitation 5~10 hours, after being cooled to room temperature, be put into ice bath, hydrogenperoxide steam generator be added, until solution becomes
For glassy yellow；Deionized water dilution is added in gained mixed liquor, vacuum filtration removes the strong acid in gained mixed liquor, filters institute
The solid obtained is washed with 5% hydrochloric acid solution, is then filtered by vacuum, obtains graphene oxide.
2) preparation of graphene oxide MODIFIED PP solution
Ethanol solution is added graphene oxide into first, utilizes ultrasonic dissolution (ultrasonic power 85W, ultrasonic time 0.5h), system
