A kind of coating of high luster water-proof color ink jet printed paper
Technical field
The present invention relates to the paint field of printing paper, particularly relate to a kind of coating of high luster water-proof color ink jet printed paper
Background technology
The color jet-ink printing technology has with other digital color printing technology ratios: the advantages such as easily doing large format output, ink needs output, ink cost relatively low by image, and image resolution ratio is high, and color rendition is true to nature.Occupy extremely important status in the digital color printing field.
Inkjet printing need to be coated with on the recording materials of ink-receiver layer just can do well image resolution ratio and color restoration capability.Particularly the aqueous jet printing-ink also needs receiving layer to have rapid absorption ability and fixation ability simultaneously, makes print image quick-drying and waterproof.
Chinese patent CN1814913 picture-grade high-light water-proof colour ink-jet printing paper adopt alumina in Nano level as main absorbing material, but the endoporus or the mesopore that its alumina in Nano level are not formed in coating describes.Also need to add in addition simultaneously strong cation dispersant and color-fixing agent in the prescription.Add more strong cation dispersant and color-fixing agent figure layer hole reduced, 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 that 90ml/100g to 200ml/100g, BET specific area are that 45m2/g to 200m2/g and average grain diameter are 1.0um to 3.0um, and the oil absorbency of described precipitated calcium carbonate-silica composite is that 100ml/100g to 250ml/100g, BET specific area are that 5m2/g to 150m2/g and average grain diameter are 1.0um to 10um.Although oil factor is described, 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.Coating gloss is not described in this patent yet.
Chinese patent CN101905582 ink jet recording medium and production method thereof, described comprising the gas permeability base material and on this gas permeability base material, sequentially arranging black receiving layer and the ink jet recording medium of superficial layer.This patent adopts two-layer coating process, and the surface layer granules of pigments is less than 100nm, and coating also needs after the coating to apply solidification liquid under moisture state through twice coating for the second time.Complex manufacturing is difficult to control.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of coating of high luster water-proof color ink jet printed paper, can absorb fast the water color ink ability, and high glaze and fixation ability can reach the effect of silver salt photographic quality.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the coating that a kind of high luster water-proof color ink jet printed paper is provided, it is characterized in that, be coated with the ink coating with high-absorbable at the type wood pulp paper of manufacturing paper with pulp, described coating mainly includes nano hydrated alumina silicate, cation dispersing agent and adhesive; Described coating also includes water repellent agent.
Preferably, described cation dispersing agent is aluminum nitrate.
Preferably, described nano hydrated alumina silicate index is: specific area (nitrogen, aerometer) 70m2/g-150m2/g, particle diameter D50 laser diffraction 50nm-100nm, the about 80-83% of dioxide-containing silica (ISO3262), alumina content 7-9.
Preferably, described adhesive is polyvinyl alcohol.
Preferably, the index of described adhesive polyethylene alcohol is: degree of polymerization 1700-3500, alcoholysis degree 88-98%.
Preferably, described water repellent agent is boric acid.
Preferably, described ultrafine hydrous alumina silicate, cation dispersing agent, the adhesive three weight ratio of also comprising is: 100: 1-3: 5-15.
Preferably, described coating also includes defoamer, levelling agent, thickener, brightening agent, wetting agent.
The invention has the beneficial effects as follows: the coating of a kind of high luster water-proof color ink jet printed paper of the present invention has quick absorption water color ink ability, and high glaze and fixation ability can reach the effect of silver salt photographic quality.
The specific embodiment
Below in conjunction with specification preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
The embodiment of the invention comprises:
A kind of coating of high luster water-proof color ink jet printed paper is coated with the ink coating with high-absorbable at the type wood pulp paper of manufacturing paper with pulp, and described coating mainly includes nano hydrated alumina silicate, aluminum nitrate, boric acid and polyvinyl alcohol.
Described nano hydrated alumina silicate index is: specific area (nitrogen, aerometer) 70m2/g-150m2/g, particle diameter D50 laser diffraction 50nm-100nm, the about 80-83% of dioxide-containing silica (ISO3262), alumina content 7-9.
The index of described adhesive polyethylene alcohol is: degree of polymerization 1700-3500, alcoholysis degree 88-98%.
Described nano hydrated alumina silicate, aluminum nitrate, polyvinyl alcohol three weight ratio are: 100: 1-3: 5-15.
Described coating also includes defoamer, levelling agent, thickener, brightening agent, wetting agent.
The present invention can absorb the water color ink ability fast, and high glaze and fixation ability can reach the effect of silver salt photographic quality.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
