(8) body paper of carbon dioxide adsorption is foamed, is cut after Temperature fall, obtain coaster paper.
The present invention mainly manufactures paper with pulp using wood pulp cellulose, bamboo fibre and polyethylene/graphene composite fibre as primary raw material together
At body paper, inventor has found when inventing creation, due to not having hydrophilic radical, pure polyethylene on pure polyethylene fibre segment
The hydrophily of fiber is poor, causes its dispersibility in mashing in softwood pulp fiber and bamboo fibre poor, therefore, this hair
It is bright to use polyethylene particle as spinning after raw material, with a certain amount of graphene melting mixing first, obtain polyethylene/graphene
Composite fibre is mixed with graphene on polyethylene/graphene composite fibre with two benefits, firstly, composite fibre can infiltrate
Anode is used as in electrolyte ammonium sulfate, then using carbon-point as cathode, after being passed through electric current, on the graphene of polyethylene surface
Oxygen-containing group can be adsorbed, secondly, graphene is mixed into the foaming for being conducive to later period fiber, this is because titanium dioxide before foaming
During carbon adsorption, the adsorptivity of carbon dioxide can be increased by being mixed into graphene, also, graphene can also the conduct in foaming
Heterogeneous nucleation point, advantageously forms abscess, when then to polyethylene/graphene composite fibre into electrochemicial oxidation, uses
Ammonium sulfate as electrolyte, be due to ammonium sulfate be neutral electrolyte, if electrolyte be acidity, poly- second can be corroded
Alkene/graphene composite fibre, and when electrolyte is alkalinity, it can be adsorbed with polyethylene/graphene composite fiber surface oxygen-containing
Group reaction, reduces degree of oxidation, also, current density has a larger impact to the adsorbance of oxygen-containing group, when energization, if electric
When current density is less than 1A/g, the electrochemical reaction of polyethylene/graphene composite fiber surface is excessively slow, and adsorbance is less, and
When current density is less than 2A/g, reaction is excessively acutely to be difficult to control degree of oxidation.The compound fibre of subsequent polyethylene/graphene
Dimension carries out the modification of 3-aminopropyltriethoxysilane, is not only able to improve its dispersibility in copy paper, moreover, being grafted on
Amino on polyethylene/graphene composite fibre can increase the carbon dioxide adsorption of polyethylene/graphene composite fibre, have
Conducive to subsequent foaming process.After polyethylene/graphene composite fibre and wood pulp cellulose and bamboo fibre are mixed with beating, it is added
Acrylic latex can be improved the retention force of fiber, this is because itself just not having binding force between fiber, increase acrylic acid
After latex, the surface that there is acrylic latex certain cohesive force to be adsorbed onto fiber forms condensation product, so that between fiber mutually
In conjunction with effectively improving the tensile index of paper.By mixed slurry by manufacturing paper with pulp, after squeezing and being dried to obtain body paper, body paper is put
Enter in carbon dioxide environment, the absorption for making surface that there is the polyethylene/graphene composite fibre of amino group to carry out carbon dioxide,
It then foams, the inside of polyethylene/graphene composite fibre can generate small abscess, greatly increase the heat-insulated of coaster paper
Performance obtains the coaster paper of required shape most afterwards after cooling, cutting.
Preferably, the mass fraction of graphene is in polyethylene/graphene complex fiber material described in step (1)
1 ‰ -2%.
Preferably, 3-aminopropyltriethoxysilane described in step (3) is the 2%-5% of ethyl alcohol quality.
Preferably, softwood pulp fiber described in step (4), bamboo fibre and 3-aminopropyltriethoxysilane are modified
Polyethylene/graphene composite fibre mass ratio be 1:0.8-1.2:1-2.
Since polyethylene/graphene composite fibre can dramatically increase the thermal insulation of body paper after expanding, but polyethylene/stone
Black alkene composite fibre is excessive or increases the production cost of body paper, and polyethylene/graphene composite fibre is in the quality in composition of raw materials
Thermal insulation than lower body paper just reaches necessary requirement, and lower production costs, and commercial interest is maximized.
Preferably, beater revolving speed 20-30HZ described in step (4), the solid content of slurry is 2wt%-4wt%.
It is beaten under this condition, polyethylene/graphene composite fibre can preferably disperse in the slurry, the body paper of manufacture
It can be preferably.
Preferably, the quality that acrylic latex is added described in step (5) is the 6%- relative to slurry solid content
10%.
If the quality of acrylic latex is very few, so that acrylic latex does not have enough amounts to be adsorbed on fiber, so that
Binding force between fiber is inadequate, and the tensile index of body paper is unable to reach demand, the knot with the increase of acrylic acid, between fiber
Resultant force increases, and tensile index can also increase therewith, but when the quality of acrylic latex is excessive, acrylic latex can be adhered to
The surface of fiber generates wadding and gathers, so very big that hinder the dispersion of fiber, and tensile index is caused to decline, therefore, anti-by inventor
Multiple experimental verification, it is determined that the mass range of required acrylic latex.
Preferably, the solid content of the acrylic latex is 35-45%.
Preferably, foaming condition is to carry out hot-pressing and foaming under the conditions of 70-90 DEG C, 1-3MPa in the step (8).
Body paper carries out the absorption of carbon dioxide first at 20-40 DEG C of low temperature, then at 70-90 DEG C of higher temperature,
The carbon dioxide of absorption can escape, to generate abscess, and the pressure of 1-3MPa be given in foaming, this is because when foaming
Body paper can expand, and pressure cannot be excessive with too small, pressure mistake when needing certain pressure to guarantee the planarization of paper, but foaming
Hour, it not can guarantee the smooth of paper, when pressure is excessive, abscess can be flattened due to bearing excessive pressure, cause abscess can not
Molding.
Therefore, the invention has the following beneficial effects: polyethylene particles and graphene melt blending, spinning, and are changed
