Description
Technical field
The present invention relates to paper surface modification technologies.
Background technique
Carrier of the paper as information, printability are particularly important in the expression of information, transmittance process.Paper
The coating technique on surface is the main path for improving its printability, it improves paper table by improving the surface texture of paper
The optical property in face improves paper surface smoothness and ink absorption, and then improves the printability of paper.Traditional coating skill
Art is mostly by manually or mechanically method, in paper surface applying implenent for the substance of appropriate rheological characteristic.Therefore, coating material must
Mobility is had both while need to having good absorbency, fineness, whiteness.To reach above-mentioned performance, coating material often ingredient
It is all complex.Such as, guarantee gelatin, polyvinyl alcohol, polyvinylpyrrolidone, the hydroxypropyl cellulose of absorbency and adhesiveness
Deng guaranteeing the water repellent agent ureaformaldehyde (UF resin) of water repelling property, melamine resin (MF resin), carbonic acid zirconates etc., guarantee coating
The defoaming agent of bubble-free guarantees that coating is evenly distributed with the lubricant etc. of property.As it can be seen that traditional coating process is not easy to control, coating is not easy
It is uniformly distributed, and contain a large amount of polluter in coating.More importantly the granularity of coating is larger, when renders image information
Resolution ratio is low, unintelligible.The reason is that can internally spread when ink touches coating particle, when particle is larger, ink expands
Serious slow drying speed is dissipated, ink cannot be absorbed in time, then be mixed diffusion in paper surface, form interlocking for color
Distribution, reducing resolution ratio causes image fuzzy.
Coating paper is produced in 1850 by the pact Wall De Lun company of NJ USA earliest, is at that time
As wallpaper.1894, occurs the equipment of First production coating paper in the world.Lightweight paper is to climb up early 1950s
Market.The pigment, adhesive and other auxiliary agents of coating are mainly studied and are developed in recent decades, the development of coating technique, with
Meet demand and coating paper lightweight requirements that information transmits the printability higher and higher to coating paper.In addition, the whole world applies
Cloth paper demand increases by 7.8% every year, and lightweight paper average growth rate per annum 22.3%, it is seen that the lightweight of coating paper is important hair
Open up direction.Lightweight obviously meets energy-saving and environment-friendly world development theme.
Summary of the invention
The invention aims to solve existing paper surface coating method of modifying to have more, the at high cost, work using ingredient
The problem that skill is complicated and light weight degree is low, and a kind of coating production for improving paper surface printing adaptability is provided.
A kind of coating production improving paper surface printing adaptability, it is sequentially included the following steps:
One, substrate material is placed on the sample stage in magnetron sputtering vacuum chamber, macromolecule target is bonded in copper target
It is placed on the target position of magnetron sputtering vacuum chamber, vacuumizes together, 20~30min of magnetron sputtering is then carried out, in substrate material
Transition zone is prepared on surface；
Two, 1~3 macromolecule target and the double target co-sputtering of Ti target are carried out, i.e., deposits and obtains on above-mentioned transition zone
TiO2/ (CH) t composite coating completes the coating preparation for improving paper surface printing adaptability；
Magnetron sputtering macromolecule target technological parameter: working gas is the argon gas of purity >=99.999%, and deposition rate is
10~150nm/min, 0.4~0.7Pa of operating air pressure, base target spacing are 6~12cm, power density 3.5W/cm2~10.0W/

The invention has the advantages that
1, the present invention adds nanoscale Si material using polypropylene, and the high score of resistant sputtering is prepared for using specific curing process
Sub- target prepares TiO with cosputtering2/ (CH) t composite coating carries out paper surface method of modifying；Preparation process need not use anti-
The auxiliary agents such as aqua, fluorescer, ingredient is simple, at low cost, and simple process is easy to operate.
2, the present invention is the breakthrough to existing Paper Coating method of modifying, prepares skill using completely new paper surface coating
Art, the macromolecule target and Ti target of design are co-located in vacuum magnetic control plasma sputtering cavity, realize paper under Ar particle bombardment
Open the composite coating deposition of surface even compact.Since in vacuum deposition process, it is mostly to receive that substance, which is in plasma state particle,
Meter level and be uniformly mixed, auxiliary agent is added there is no need to consider mobility, easily formed large area uniform coating；Cosputtering deposition
TiO2/ (CH) t composite coating has excellent absorbency and smoothness because having the microcellular structure of natural nanometer, greatly improves
The precision of information regeneration；Composite coating has (CH) t structure and there are water-resistance, and there is no need to additionally add water repellent agent；Vacuum
Any subsidiary pollutant is not generated in the preparation process of magnetic control co-sputtering；TiO2High reflectance, refractive index greatly improve paper
Whiteness and the optical properties such as opacity；The paper generation for preparing coating is manufactured paper with pulp with natural fiber is chemically bonded, rather than
Simply, single physical attachment, thus be not susceptible to conventional coating methods and generated because tiny coating is with paper base poor bonding strength
Picking phenomenon, the present invention significantly improves the printing adaptability of paper surface.
3, the TiO that the present invention is prepared using magnetic control co-sputtering method2/ (CH) t coating, due to having above-mentioned excellent characteristics,
The lightweight of paper higher degree can be realized in the case where paper meets printability requirement, therefore the present invention has important environmental protection
Value and social effect.
