Particulate matter in mass ratio 1 after immersion：1 ~ 3 is added mixed liquor, is stirred, and filters, takes filter residue a；
D. it takes printing waste paper to crush, soaks, be dispersed with stirring then at 2000r/min, obtain dispersion liquid, take dispersion liquid in mass ratio
10：3 are added filter residue a, and 30 ~ 50min is kept the temperature in 35 ~ 40 DEG C, and the neopelex for adding dispersion liquid quality 10% carries out
10 ~ 15min of flotation takes paper pulp distilled water flushing after flotation, pours into mold molding, dry to get coating paper base paper.
The preparation method of the coated paper coatings includes the following steps：
（1）According to the mass fraction, 60 ~ 100 parts of cornstarch, 6 ~ 10 parts of glycerine, 10 ~ 14 parts of chloroacetic acids, 8 ~ 12 parts of hydrogen-oxygens are taken
Change sodium, 30 ~ 40 parts of water are stirred, and are placed in twin-screw extruder reactor, are added the ring of cornstarch quality 0.1 ~ 0.3%
Oxygen chloropropane keeps 2 ~ 3h in 250 r/min, dry, pulverize sieving, collects sieving particle A；
（2）Take sieving particle A in mass ratio 3：2 are added distilled water, are warming up to 70 ~ 75 DEG C and are stirred, obtain stirring mixture, press
Mass fraction meter, take 200 ~ 300 parts stirring mixture, 1 ~ 3 part of glycerine, 2 ~ 5 parts of citric acid three esters, in 65 ~ 70 DEG C keep the temperature 1 ~
2h adds the glutaraldehyde of 2 ~ 3 times of glycerine quality, is stirred 2 ~ 3h, is cooled to room temperature, obtains coolant liquid, spare；

It is stirred 3 ~ 4h to 95 ~ 100 DEG C, obtains mixture, according to the mass fraction, takes 5 ~ 8 parts of calcium carbonate, 12 ~ 15 parts of china clay, 20 ~ 30
Part step（2）Spare cooling thing, 15 ~ 20 parts of mixtures, 0.3 ~ 0.6 part of polyacrylic acid, 30 ~ 40 parts of water, are stirred in 3000r/min
Mixing is mixed to get coated paper coatings.
The preparation method of the coating paper, includes the following steps：Take coated paper coatings by 15 ~ 18g/m2Applying amount in painting
It is coated on cloth machine in coating paper base paper, it is dry to get coating paper in 70 ~ 80 DEG C.
Compared with other methods, advantageous effects are the present invention：
（1）The present invention acts synergistically by cellulase, alpha-amylase, the ink on removal printing waste paper surface, cellulase quilt
It is adsorbed on the surface of paper pulp fiber and cellulase biological hydrolysis occurs, cellulose surface is made more cellulosic molecules occur
End group, to create condition for enzyme hydrolysis cellulose, cellulase acts on the ink-that printing waste paper generates after size degradation
On fiber and fiber-ink, cellulase acts preferentially on the irregular region of fibre structure, makes the fibre structure in these regions
Become loose, fibre strength becomes to weaken, and weakens the mutual combination of surface microfibre, increases microfibre oneself
By being aided with alpha-amylase, can randomly act on α-Isosorbide-5-Nitrae-glycosidic bond in starch, hydrolysis generating glucose, maltotriose, paste
The small-molecule substances such as the reduced sugars such as essence, hydrolysis while, make the viscosity of starch reduce, so as to help to be attached to fiber table
The removing of ink particle on face reduces broken ring and the loss of paper pulp fiber, and Deinking Efficiency is high, and low energy consumption；
（2）The present invention is fixed on the mixed enzyme of cellulase, alpha-amylase on silica gel with using glutaraldehyde, recycles and fixes
Enzyme carry out printing waste paper deinking, by gross porosity microsphere silica gel made from sodium metasilicate, hydrochloric acid be raw material, add Ludox to bond
Particulate matter is made in silica gel-Ludox mixture by agent, and one end of glutaraldehyde is connected on the amino of enzyme, and the other end is then connected on
On the hydroxyl of silica gel, to reach the stability that immobilised enzymes ensure that enzyme, removing utilization rate is improved, and convenient for separation and again
It is multiple to utilize, reduce the cost of coating paper base paper preparation；
（3）The present invention with styrene, methyl acrylate, divinylbenzene etc. for raw material, using Soap free cationic emulision technology
Complex emulsions are prepared, being one kind has hollow type plastic pigment, and after by coating waste water, the painting of ingredient is played based on pigment
Material can be covered in the surface of fiber and fleeces aggressiveness, to fill and lead up body paper depression in the surface and microcosmic unsmooth place, production
A kind of new surface with less concave-convex shape is given birth to；
（4）The present invention is prepared for starch derivatives, conduct using cornstarch as primary raw material, by nanosizing and carboxy methylation
Nano-high molecule electrolyte, not only the gap between paper pulp fiber carried out filling, cohere, good film-forming property, film is smooth, saturating
Lightness is high, water retention property is preferable, as primary raw material, using citric acid three ester, glycerine as plasticizer, and follow-up addition penta 2
Aldehyde progress is cross-linking modified, prepares and is used as gluing agent emulsion, and hydrophily is strong, and diameter grain is smaller, and can pigment particles be carried out with package and filled out
It fills, increases paper smoothness, also enhance the surface strength of coating paper, be filled with and institute is unevenly distributed by fiber and pigment
Caused by hole, the phenomenon that reducing fracture, blistering.
