Description
Technical field
The present invention relates to technical field of daily necessities, more particularly, to a kind of graphene oxide antibacterial wet tissue.
Background technique
Wet tissue is to select wet strong soft fine high osmosis substrate, and disposable cleaning health is made through folding, humidification, packaging and uses
Product have the characteristics that cleaning, the basic function of moisturizing skin and easy to carry, become essential in people's daily life
Cleaning supplies.Hygenic towelette is usually to be made of substrate and medical fluid two parts, wherein substrate wet-strength paper or spunlace non-woven cloth, medical fluid base
Plinth formula includes water, moisturizer, preservative and nonionic surfactant.Preparation method is that substrate is put into the liquid leaching
Bubble, then takes out substrate sealed package up to the hygenic towelette.Bacterium and mould in the production process of wet tissue, in air
Class is easy to be mixed into pollution, and wet tissue is caused to pollute.Currently, usually using methylisothiazolinone, methyl chloride isothiazoline in wet tissue
Ketone, the chemical bactericides such as Bian rope chloramines and cetylpyridinium chloride, such chemical bactericide moderate toxicity is irritant, deposits
Using security risk.In order to avoid using the virose preservative of tool, achieve the purpose that inhibit bacterium and Mycophyta breeding, now
There is technology that the ethyl alcohol of high concentration is added usually into wet tissue, but concentration of alcohol is more than 50%, and the people of skin fragility contains in use
When having the wet tissue of the concentration alcohol, it may appear that skin surface sebum dissolves excessive phenomenon, causes to have dry skin, even results in allergy
Reaction.
Therefore, preferably safety, the appearance of mild wet tissue are very necessary for the inhibitory effects such as a kind of pair of bacterium mould.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies that existing wet tissue does not have enough anti-microbial properties, provide one
Kind graphene oxide antibacterial wet tissue, passes through and adds graphene oxide modified cellulose composite plant in wet tissue paper base preparation process
Antimicrobial extract, antibacterial material load is more stable, greatly improves the anti-microbial property of wet tissue.
Above-mentioned purpose of the present invention is achieved through the following technical solutions：
A kind of graphene oxide antibacterial wet tissue, following method are prepared：
S1. by wood pulp cellulose and cotton fiber mixed pulp, shaping fiber paper base is obtained by manufacturing paper with pulp, before fiber paper base

S2. the wet tissue substrate in S1 is infiltrated in immersion fluid, takes out wet tissue substrate and obtains graphene oxide moist antibacterial
Towel,
Antibacterial accessory ingredient is the mixture of graphene oxide modified cellulose, banaba extract, Flos Caryophylli extract in the S1.
Wood pulp cellulose and cotton fiber are all natural cellulosic feedstocks, have good hygroscopicity, gas permeability and biodegrade
Property, there is good biodegradable by wet tissue substrate prepared by wood pulp cellulose and cotton fiber.Graphene oxide modified cellulose
The retention and steady load that antibacterial agent can be improved is added in antibacterial agent during the preparation process.
Crape myrtle and cloves all have good bactericidal effect in the present invention, and being used in compounding also has good fresh scent,
Bacteria breed can be not only prevented, but also its fresh scent can be assigned with the sensory evaluation of wet tissue.Graphene oxide
(graphene) refer to that tightly packed bi-dimensional cellular shaped single layer of carbon atom, single-layer graphene oxide have big ratio table
Area has certain anti-microbial property and porosity, and good carrier space can be provided for crape myrtle and cloves by being used in compounding, and be made
Obtaining crape myrtle and cloves can sufficiently load and be adsorbed in graphene oxide space, obtain good antibacterial effect.
Crape myrtle first through drying, crushing, is then impregnated with ethyl alcohol, heating and refluxing extraction 2-3 times, each 0.5-2h, merging mentions
Liquid is taken, filters, be concentrated to give ethanol extract.
Preferably, antibacterial described in S1 is helped including following mass fraction component：Graphene oxide modified cellulose 0.3~
