A kind of coating preparing process of high luster water-proof color ink jet printed paper
Technical field
The present invention relates to the coating field of printing paper, particularly relate to a kind of coating preparing process of high luster water-proof color ink jet printed paper.
Background technology
Color jet-ink printing technology, has with other digital color printing technology ratios: easily do that large format exports, ink needs to export by image, ink advantage of lower cost, the advantages such as image resolution ratio is high, and color rendition is true to nature.Extremely important status is occupied in digital color printing field.
Inkjet printing needs on the recording materials being coated with ink-receiver layer, just can do well image resolution ratio and color restoration capability.Particularly aqueous jet printing-ink, also needs receiving layer to have rapid absorption ability and fixation ability simultaneously, makes printed drawings as quick-drying and waterproof.
Chinese patent CN1814913 picture-grade high-light water-proof colour ink-jet printing paper, adopts alumina in Nano level as dominant absorption material, but the endoporus do not formed in the coating its alumina in Nano level or mesopore are described.Also need to add strong cation dispersant and color-fixing agent in addition in formula simultaneously.Add more strong cation dispersant and color-fixing agent will certainly make layer hole reduce, affect rapid absorption ability.Be difficult to realize quick-drying and high image resolution ratio.
The preparation method of Chinese patent CN1723133 ink jet recording medium, described pigment contains synthetic silica and/or precipitated calcium carbonate-Silica composite, the oil absorbency of described synthetic silica is 90ml/100g to 200ml/100g, BET specific surface area be 45m2/g to 200m2/g and average grain diameter is 1.0um to 3.0um, and the oil absorbency of described precipitated calcium carbonate-Silica composite is 100ml/100g to 250ml/100g, BET specific surface area be 5m2/g to 150m2/g and average grain diameter is 1.0um to 10um.Although be described oil factor, the pigment of average grain diameter 1.um to 3.0um and average grain diameter 1.0um to 10um can not form the coating of high glaze.Also coating gloss is not described in this patent.
Chinese patent CN101905582 ink jet recording medium and production method thereof, the ink jet recording medium of described black receiving layer comprising gas permeability base material and sequentially arrange on this gas permeability base material and superficial layer.This patent adopts two-layer coating process, and surface layer granules of pigments is less than 100nm, and coating, through twice coating, also need apply solidification liquid after second time coating under moisture state.Complex manufacturing, is difficult to control.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of coating preparing process of high luster water-proof color ink jet printed paper, and the preparing process of coating can be made simple, and the coating of preparation compares uniform and smooth, makes coating have good cohesive and Painting effect.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the coating preparing process providing a kind of high luster water-proof color ink jet printed paper, its processing step is: 200L disperses to add 49.2kg deionized water in bucket by (1), start dispersion machine high speed dispersion, add people's aluminum nitrate 0.5kg successively, boric acid 0.3kg, alumina silicate 20kg; Disperse after 1-2 hour, disperse to circulate in bucket sand milling 2-4 hour by sand mill at 200L, make component A; The volume of described sand mill is 10L, and the diameter of the pure zirconium pearl in sand mill is 2mm, and packing ratio is 60%; (2) add 27kg deionized water by 50L dissolving tank, start agitator, add the polyvinyl alcohol that brand is river dimension 2488, be warmed up to more than 95 DEG C, constant temperature was down to room temperature after 1 hour, made B component, wherein polyvinyl alcohol content 10%; (3) be the 10% polyvinyl alcohol water solution 30kg that river ties up 2488 by the brand of having dissolved, join under high speed dispersion in component A, be uniformly dispersed.
Preferably, the liquid in described dispersion bucket after circulation sand milling, solid particle size D50 laser diffraction 98nm.
The invention has the beneficial effects as follows: the coating preparing process of a kind of high luster water-proof color ink jet printed paper of the present invention can make the preparing process of coating simple, and the coating of preparation compares uniform and smooth, makes coating have good cohesive and Painting effect.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The embodiment of the present invention comprises:
A kind of coating preparing process of high luster water-proof color ink jet printed paper, its processing step is: 200L disperses to add 49.2kg deionized water in bucket by (1), starts dispersion machine high speed dispersion, adds people's aluminum nitrate 0.5kg successively, boric acid 0.3kg, alumina silicate 20kg.Disperse after 1-2 hour, disperse to circulate in bucket sand milling 2-4 hour by sand mill (the pure zirconium pearl of volume 10L, diameter 2mm, packing ratio 60%) at 200L, make component A; (2) add 27kg deionized water by 50L dissolving tank, start agitator, add polyvinyl alcohol (river dimension 2488), be warmed up to more than 95 DEG C, constant temperature is near room temperature after 1 hour, makes B component (polyvinyl alcohol content 10%); (3) 10% polyvinyl alcohol (the river dimension 2488) aqueous solution 30kg will dissolved, joins under high speed dispersion in component A, is uniformly dispersed; Liquid in described dispersion bucket after circulation sand milling, solid particle size D50 laser diffraction 98nm.
The present invention can make the preparing process of coating simple, and the coating of preparation compares uniform and smooth, makes coating have good cohesive and Painting effect.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
