Description
Technical field
The present invention relates to a kind of edible oil removing towel and preparation method thereof, belong to the technical field of daily living article.
Background technology
In life, oils and fats overstock problem is serious now, and the oils and fats of Excess free enthalpy endangers the healthy of people.Daily life
In work, people often stew meat soup, and Boiled fish etc., due to personal habits, health, the difference of living condition, a lot of people practise
It is used to only to eat soup and does not likes one layer of oils and fats above, but this layer of oil is difficult to again remove.
Summary of the invention
For above-mentioned problems of the prior art, the present invention provides a kind of edible oil removing towel and preparation method thereof, should
Edible oil removing towel can conveniently remove oils and fats unnecessary in family life.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is:
A kind of edible oil removing towel, has the nontoxic material main body of several micropore including surface configuration.Sized by micropore consistent
Hole, it is also possible to sized by inconsistent hole, it is also possible to sized by inconsistent and irregular hole.
As the further setting of such scheme, described micropore to the internal extension of nontoxic material main body, is formed from outside to inside
Microchannel.
Described nontoxic material main body be internally provided with a containing cavity, containing cavity connects with all microchannels, or hold
Put chamber to connect with part microchannel.
The containing cavity being internally provided with more than one quantity of described nontoxic material main body, a containing cavity and one micro-logical
Road connects, or a containing cavity connects with the microchannel of more than one quantity.
The specification of edible oil removing towel is preferably: a length of 150mm, width is 150mm, and thickness is 6mm.
Described nontoxic material main body is degradable non-poisonous material main body, or nontoxic material main body is degradable, renewable
Nontoxic material main body.
The present invention eats oil removing towel, can be selected for the bio-based macromolecular materials such as polylactic acid, cellulose, starch plastic and makes.
The micropore that the present invention eats on oil removing towel is formed by the way of foaming, and concrete grammar has physical blowing method and chemistry
Foaming two kinds.Physical blowing method be raw material is dissolved in gas (or liquid) afterwards gasify formation micropore, or by material dissolution in
Separate out after solvent and form micropore, dissolve soluble constituent simultaneously and form abscess.Chemical blowing process is CBA decomposes
Or other chemical reactions produce gas, raw material melt is made to form micropore.
The present invention eats oil removing towel, and two kinds of different physical blowing methods can be used to be prepared, and first kind of way specifically walks
Suddenly it is:
(1) feed intake: dry bio-based macromolecular material is put in double screw extruder by feeding system；
(2) extrusion plasticizing: by double screw extruder by the mixing plasticizing of bio-based melt polymer material, temperature is 160-
200℃；
(3) supercritical carbon dioxide is injected: utilize supercritical carbon dioxide gas injection system to inject in double screw extruder
Supercritical carbon dioxide, more than 7%, (injection rate refers in mass fraction, and double screw extruder the injection rate of carbon dioxide
The extrusion capacity contrast of raw material.As: when in double screw extruder, the extrusion capacity of raw material is 100 grams, then the injection rate of carbon dioxide
It is more than 7 grams), injection pressure is at more than 10MPa；
(4) high pressure extrusion: the head pressure of double screw extruder controls at more than 70MPa；
(5) foaming: after the head of double screw extruder is extruded, forms finished product.
The second way concretely comprises the following steps:
(1) material dissolution: dry bio-based macromolecular material is dissolved in solvent orange 2 A, and controls bio-based macromolecule
The concentration of material is 0.05-0.15g/mL；Any during wherein solvent orange 2 A is chloroform, dichloromethane, dioxane, acetone
A kind of；
(2) solvent B is added: be slowly added dropwise the solvent B of insoluble bio-based macromolecular material, bio-based macromolecular material meeting
Separate out along with the increase of solvent B addition；Any one during wherein solvent B is dehydrated alcohol, hexane, ether；
(3) molding: precipitation solid phase is collected in mould；
(4) it is dried: remove residual solvent by blast heating, obtain finished product.
The edible oil removing towel formed by both physical blowing methods is to have nanometer and the material of micron order micropore, and it is at sky
In gas, the contact angle to water is more than 100 °, and the contact angle to oil is 0 ° in atmosphere.
The present invention eats oil removing towel, and what employing chemical blowing process was prepared specifically comprises the following steps that
(1) feed intake: dry bio-based macromolecular material and CBA are put into twin screw by feeding system
In extruder；Wherein, any during CBA is sodium bicarbonate, azodicarbonamide, sodium carbonate-citric acid foaming system
A kind of；The addition of CBA be the 3-30%(of institute's substance gross mass i.e., when bio-based macromolecular material and chemistry
When the interpolation gross mass of foaming agent is 100 grams, CBA accounts for 3-30 gram)；
(2) extrusion plasticizing: by double screw extruder by the mixing plasticizing of bio-based melt polymer material, temperature is 140-
270℃；
(3) foaming: after the head of double screw extruder is extruded, forms finished product.
The edible oil removing towel formed by this chemical blowing process is to have nanometer and the material of micron order micropore, and it is in atmosphere
The contact angle of water is more than 100 °, and the contact angle to oil is 0 ° in atmosphere.
Bio-based macromolecular material (such as polylactic acid, cellulose, starch plastic) possesses plant origin and biodegradable two
Big characteristic, compared with common petroleum based high molecular, bio-based macromolecule typically can reduce the petroleum resource consumption of 30-50%, reduces
People's dependence to petroleum resources.Bio-based macromolecule derives from biomass simultaneously, and discarded goods can be with organic waste one
Play compost treatment, ultimately re-enter biological cycle.Based on bio-based these good characteristics high molecular, it is made into hydrophobic
Lipophile foaming poromerics, for removing oils and fats unnecessary in family life.
The present invention eats oil removing towel, can easily remove the oil on soup class surface and leave behind soup, can help people reduce for
The absorption of oils and fats.In addition, the present invention is also applied to other aspect oil removings of family life, and high-efficient simple is quick.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the sectional structure schematic diagram of the present invention；
Fig. 3 is the sectional structure schematic diagram of another structure of the present invention.
Detailed description of the invention
As it is shown in figure 1, the present invention eats oil removing towel, there is the nontoxic material main body 1 of several micropore 2 including surface configuration.Micro-
Hole consistent sized by hole 2, it is also possible to sized by inconsistent hole, it is also possible to sized by inconsistent and irregular hole.
For improving oil absorbency, the micropore 2 of the present invention to the internal extension of nontoxic material main body 1, forms microchannel from outside to inside
3, as shown in Figure 2 and Figure 3.
