Description
Technical field
The present invention relates to a kind of prepare paper method and should the obtained paper of method.
Background technology
From the appearance of the nineties 3D printer in last century, to today, 3D printing technique has been applied to a lot of field, as architectural design, industry pattern, cartoon model, medical treatment etc.The principle of 3D printing technique: 3D printing is a kind of form of additive manufacturing technology, in additive manufacturing technology, three dimensional object creates out by continuous print physical layer, adopt layering processing, superposition shaping, the printing of every one deck in two steps, first one deck glue (i.e. curing agent, adhesive is sprayed in the shaping region of needs, the bonding of follow-up main material is formed design 3D finished product), glue drips that itself is very little and not easily spread; Then be spray the uniform main material of one deck (as metal dust, plastic powders).Main material powder runs into glue and can bond by rapid solidification, and does not have the region of glue still to keep loose condition (of surface).So alternately spray one deck glue one deck powder, physical model will be printed as type, after printing, as long as clear away loose powder can obtain physical model, and the bulky powder also reusable edible of cleaning.
Manufacturing paper with pulp of current paper needs through following steps usually: slurry disperses, and adds chemical drug, Top wire former, and squeezing is dried.Can consume a large amount of water, gases at high pressure, steam and electric power in this pulping method, produce a large amount of waste water simultaneously, energy resource consumption is very large and there is a large amount of chemical drugs in the waste water produced in copy paper, forms burden to environment.And existing copy paper processing procedure is always towards the future development of high fabric width, the high speed of a motor vehicle, the weight of a general coil paper is more than 2 tons, if need examination to copy a small amount of new paper kind, manufacture paper with pulp and can cause a large amount of waste as directly gone up paper machine and comparatively be difficult to ensure that the physical property that card institute produces paper product is stablized, and in prior art, lack a kind of method of can manufacture paper with pulp multiple types and the paper product of demand on a small quantity.
Summary of the invention
In view of this, provide a kind of method preparing paper, the method is applicable to manufacture paper with pulp multiple types and a small amount of paper product of demand.
In addition, there is a need to provide a kind of paper applied obtained by said method.
Prepare a method for paper, it utilizes the 3D printing technique using main material and glue, and main material adopts the slurry being dispersed into single fiber; The computer that use equipment comprises 3D printer and is connected with 3D printer, prepare the three-dimensional stereo model of paper needed for being designed with in computer, and the shaping information that slicing delamination obtains each primary layers of material and glue layer has been carried out to the three-dimensional stereo model of this paper; 3D printer prints according to the shaping information of every layer, and glue and slurry are alternately sprayed out, and final paper is printed as type.
The present invention is by utilizing 3D printing technique, adopt the main material that the slurry being dispersed into single fiber prints as 3D, by alternately spraying one deck glue one deck slurry, paper is made to be printed as type, the method effectively reduce traditional paper produce in every energy resource consumption such as water, electricity, gas, be suitable for a small amount of product, articles made to order are produced, and the paper production of special functional demands.
Detailed description of the invention
The present invention prepares the method for paper, utilize 3D printing technique, adopt the main material that the slurry being dispersed into single fiber prints as 3D, adopt the glue of 3D printing technique routine use as glue, by alternately spraying one deck glue one deck slurry, glue layer and pulp fiber layer are alternately formed, and final paper is printed as type.All kinds of glue that can play bond effect of glue for using in daily life that 3D printing technique routine uses, as resinae, acrylic compounds, silicone etc.
The equipment that 3D printing technique uses is 3D printer, is provided with multiple print cartridge, has the print cartridge in order to accommodating glue, have the print cartridge in order to accommodating main material (slurry) in 3D printer.The three-dimensional stereo model preparing paper needed for being designed with in the computer be connected with 3D printer (is equivalent to set the shape of required print paper, size specification etc.), and slicing delamination is carried out to the three-dimensional stereo model of this paper, the shaping information obtaining every layer (is equivalent to design the shape of each primary layers of material and glue layer, size specification etc.), 3D printer prints according to the shaping information of every layer, control the course of main material (slurry) and glue respectively, slurry in print cartridge and the glue in print cartridge are alternately sprayed out, finally obtain required paper.
In slurry of the present invention, the mass percentage of moisture content is below 10%.This slurry is preferably air-dry slurry, and air-dry slurry is slurry dry under field conditions (factors), and in general air-dry slurry, the mass percentage of moisture content is below 10%.Wind slurry is for oven dry stock and wet pulp, and wet pulp is that in general wet pulp, the mass percentage of moisture content is more than 50% from pulp mill out without the slurry dehydrated; Oven dry stock is the noun used in the lab, and not water content in oven dry stock, in order to calculate the ratio of each composition such as slurry, chemical drug in copy paper or experimentation.
The kind of this slurry is not limit, and can be wood pulp, straw pulp etc., and the alternative fiber adding the other types such as metal fibre, carbon fiber.
Containing at least one in long fibre and short fiber in described slurry, the ratio of length fibre can set according to the demand of paper physical property.In general, long fibre has the advantages that intensity is high, percentage elongation is large, but price is also higher, and in general paper production, long fine shared mass percentage is 10%-30%.Long fine and short fiber in described slurry puts into same print cartridge according to after the mixing of certain ratio, and in print procedure, long fibre sprays out together with short fiber is from same print cartridge; Also can add different print cartridges respectively according to certain ratio, printing duration fibre and short fiber spray out while certain ratio is from different print cartridge.
For realizing the different efficacies of sheet paper products, also can optionally add the additives such as chemical drug, essence, bacteriostatic agent, coloring agent in paper preparation process.Additive can mix rear loading main material print cartridge with slurry, spray in print procedure with slurry; This additive also can leave in separately in a print cartridge, sprays as required in print procedure, and this kind of method can determine additive point of addition in the product, i.e. paper inside or paper surface.
The present invention is by utilizing 3D printing technique, adopt the main material that the slurry being dispersed into single fiber prints as 3D, by alternately spraying one deck glue one deck slurry, paper is made to be printed as type, the method effectively reduce traditional paper produce in every energy resource consumption such as water, electricity, gas, be suitable for a small amount of product, articles made to order are produced, and the paper production of special functional demands.
In addition, those skilled in the art also can make various amendments in other form and details, interpolation and replacement in the claims in the present invention scope of disclosure and spirit.Certainly, the changes such as these various amendments made according to the present invention's spirit, interpolation and replacement, all should be included within the present invention's scope required for protection.
