Description
Technical field
The present invention relates to pulp technology for making paper, and in particular to a kind of coating for producing art paper and its application.
Background technology
Art paper is the front cover for being mainly used in printing advanced books and periodicals with text paper made of body paper coating white coating
With illustration, colored picture, various exquisite Commdity advertisements, sample, commodity packaging, trade mark etc..The quality of the performance of art paper is determined
Determine the final mass of print product, the printing colouring effect that excellent art paper can obtain is on the contrary then poor.
The performance evaluating of art paper is glossy, smoothness, whiteness and ink absorption etc., wherein, glossiness and oil
Quality influence of the black absorbability on art paper is very big, and its coating to art paper requires very high, therefore, in order to obtain high quality
Art paper, it is necessary to be correspondingly improved to its coating.The coating of present art paper mainly by calcium carbonate, china clay or the two match somebody with somebody
Close and use, add a certain amount of adhesive and other auxiliary materials, copperplate paper roughness, glossiness, surface strength, the ink of gained are inhaled
Receive property etc. index cannot be bigger improvement, had a strong impact on subsequent use.
The content of the invention
In view of the above-mentioned problems, the present invention proposes a kind of coating for producing art paper, and use this kind of coating material production copperplate
Paper, improve the oil absorbency of art paper and improve its glossiness.
A kind of coating for producing art paper of the present invention, in parts by weight, its raw material composition is：Diatomite 50-80
Part, calcium carbonate and/or china clay 20-50 parts, styrene-butadiene latex 5-10 parts；PVA 1-3 parts, lubricant 0.1-1 parts, defoamer 0.05-
0.2 part, water-loss reducer 0.1-2.0 parts, water repellent agent 0.2-2.0 parts, dispersant 5-10 parts, add water adjusting coating solid content 60-
80wt%.
Diatomite is a kind of biogenic siliceous sedimentary rock, and it is mainly made up of the remains of ancient times diatom.Its chemistry
Composition is with SiO2Based on.It is diatomaceous soft, it is porous and light, the special porous structure of natural diatomaceous earth can be observed under microscope
Make, this microcellular structure is that diatomite has the reason for feature physicochemical property.Such as：Porous, relatively low density, larger ratio
Surface area, relative Incoercibility and chemical stability etc., can provide excellent surface property for coating, increase-volume, thicken with
And improve adhesive force.Because it has larger pore volume, film can be made to shorten drying time.The dosage of resin can be also reduced,
Reduce cost.
In the present invention, diatomite, calcium carbonate, china clay are all pigment, and their effect is to fill the rough surface of body paper, is carried
The optical properties such as the whiteness of high paper, opacity, glossiness；Smoothness is improved, improves the ink absorption of paper, obtains paper
Good printing adaptability.In order to ensure the quality of final art paper, the diatomaceous SiO of the present invention2Content >=80%, fineness >=
1340 mesh；Calcium carbonate and china clay fineness are more than 98 grades；
Styrene-butadiene latex and PVA are adhesive, and effect is that pigment particles are bonded on body paper；Pigment particles are made to glue mutually
Knot；The space partly filled up between pigment particles；Microcellular structure is covered, and keeps the viscosity and water-retaining property of coating.The present invention
The advantages of styrene-butadiene latex and PVA are with the use of being to make full use of both sides, the heat-resisting and wearability of styrene-butadiene latex is preferable, and
It is cheap；PVA bonding force is very strong, but cost is higher.The quality requirement of influence and paper in view of production cost, this
Styrene-butadiene latex and PVA mass ratio are 1-10 in invention:1.
The effect of lubricant is slip coating and improves its flow behavior, ensures more smooth coating, and the present invention uses
The DS-RH320 of modified high-molecular polythene class soluble oil, preferably Shandong Dong Sheng new materials company；
The effect of defoamer is to eliminate the bubble in coating, avoids that paper defects occurs and is coated with obstacle, the preferred Bark of defoamer
The BUBREAK4881 of Man.
Water-loss reducer ensures that coating moisture during circulation is not lost in, so as to ensure that the solid content of coating is consistent, water conservation
Agent preferably carboxymethyl cellulose.
Water repellent agent uses PAPU water repellent agents, and beneficial SR-5030 is gathered in preferably Suzhou, is mainly added to paper moisture-resistant frictional strength.
Dispersant uses polyacrylate coating dispersant, preferably ten thousand bold and unconstrained DC-40 of Shandong, and the effect of dispersant is to ensure
Flocculation and sedimentation phenomenon do not occur for the pigment in coating, and make the viscosity of coating as low as possible, have good mobility and painting
Cloth adaptability, the Combination of adhesive and pigment is improved, to reach the effect for improving coating paper surface strength and printing adaptability.
Using raw material of the present invention and its proportioning, it is ensured that runnability of the coating in coating process, coating
Every physical index of paper, the performance in the follow-up printing process of paper and production cost afterwards.
Using the method for coating material production art paper of the present invention, body paper production 70-120g/m2, coating weight presses 20-
40g/m2Control, it is divided into four coating head two sides and applies；Calender is the nip of 11 roller 10, calendering pressure 100-200KN/m, press polish temperature
50-100 DEG C of degree；Compared with prior art, because diatomaceous Incoercibility is relatively large, calender pressure improves 20-
50KN/m, temperature improve 5-10 DEG C.
The present invention using diatomite makees main pigments, be equipped with part calcium carbonate or china clay, adhesive, lubricant, defoamer,
The auxiliary materials such as water-loss reducer, water repellent agent, dispersant, art base paper positive and negative is coated on, turns into qualified high-quality after supercalendering
Art paper.The art paper ink absorption obtained using coating of the present invention is significantly improved, and glossiness and surface strength are equal
Higher than conventional products.

Product quality situation contrasts：
| Quantitative g/m2 | Roughness um | Surface strength m/s | Glossiness % | Ink absorption % | |
| Embodiment 1 | 104.9 | 1.12 | 1.41 | 68.4 | 26.2 |
| Embodiment 2 | 115.4 | 1.06 | 1.55 | 71.1 | 29.3 |

| Conventional (100%CaCO3) | 108.8 | 1.65 | 1.25 | 63.5 | 23.1 |
Data analysis：Close quantitative product index is contrasted, the pigment that the product of contrast uses is calcium carbonate,
The mainly diatomite that the present invention uses.In terms of result, roughness is significantly lower than conventional products, and glossiness is higher than conventional products,
Main cause is that diatomite quality is softer, is easier in supercalendering by ornamenting, produces preferably smooth and gloss；Surface is strong
Degree be higher than conventional products, main cause be diatomite compared with calcium carbonate, have bigger specific surface area, thus with adhesive
With reference to more firmly, and the adhesive force of itself is all big, therefore can produce bigger table in the case of identical adhesive dosage
Surface intensity；Above all ink absorption significantly improves, and main cause is that diatomite has special vesicular texture, this more
Cavernous structure can not only improve the rate of drying of page during coating, reduce steam consumption, and can print
The seepage velocity of ink is improved in journey, ink absorption is greatly speeded up, printing efficiency can be improved.
