Abstract
As the main Chinese white in the dyed layer of water writing paper, can improve the contrast and the durability of water writing paper with atlapulgite.Utilize the surperficial adsorptivity of atlapulgite, prolong the retention time of water-color paintbrush handwriting, thereby reach the purpose of utilizing water-color paintbrush to practice calligraphy.
Description
The present invention is the improvement that belongs to water writing paper.
Water writing paper, be a kind of special processing paper, on the water writing paper paper, the available prepared Chinese ink of not being stained with, and the writing brush that gets wet (being commonly referred to as water-color paintbrush) is write, when writing, presented black or redness by the position of water-wet, treat certain hour after, because water is absorbed or evaporates by paper, the water Lock-out, the former form and aspect that present disappear thereupon on the paper, revert to original paper.
Before the present invention made, water writing paper was to make by being arranged on the low-refraction pigment coloring layer that is on background color layer black or that other are dark-coloured.This dyed layer is white in color before use, and when using water-wet, the anaclasis disappearance promptly presents the form and aspect of background color layer clearly, and dyed layer usually used material is microencapsulation material or silica, aluminium oxide, carclazyte, calcium carbonate, magnesium carbonate etc.Wherein, the dyed layer that contains microencapsulation material has the feature of similar " rice paper ".Because when producing the water writing paper of microcapsules dyed layer, need to be equipped with the equipment of preparation microcapsules, simultaneously, it is higher that microcapsule raw material and coating prepare expense, the water writing paper that the microcapsules dyed layer is made, because friction causes breaking of microcapsules easily, produce cut on paper, it is better that the water of silica-based Chinese white is write effect, but the cost height, the refractive index of carclazyte and calcium carbonate is high slightly, the dyed layer that is made of it, when water is write, it is poor slightly to present the writing contrast, and the retention time of writing is also shorter.
Purpose of the present invention is to adopt atlapulgite as the pigment in the dyed layer.This pigment has than microencapsulation material on cost of material and silica is cheap and writing effect is better than the advantage of carclazyte and calcium carbonate.
Another object of the present invention is the Chinese white of selecting for use, prolongs the retention time that water is write writing as far as possible.
As everyone knows, atlapulgite is to be raw material with the bentonite, handle with sulfuric acid, and Shui Xi a kind of Chinese white then, its specific area can reach 200 meters
2More than/the gram, because the atlapulgite surface has very big adsorptivity.Thereby, the time that on the atlapulgite surface, keeps the moisture content of water-color paintbrush, longer than other pigment.In addition, the Main Ingredients and Appearance of atlapulgite is SiO
2And Al
2O
3, its refractive index is very low, and it is better that water is write the contrast of writing, the atlapulgite that is adopted, its whiteness should be more than 75%.
The background color layer of water writing paper requires to be dark tone, and has certain filming performance and resistance to water.It can control the degree that the moisture content after water is write permeates to paper substrate, and it is made up of pigment, adhesive and some auxiliary agents.
Adhesive can adopt the resin solution or the aqueous emulsion of various resistances to water, as polyacrylic acid latex, carboxylic styrene butadiene latex, acrylate (or methacrylate)/styrene copolymerized emulsion casein or modified casein, synthetic or natural glue such as polyvinyl alcohol (1799 specification).The retention time of writing was decided after concrete selection kind should be write on water.Retention time is long, selects for use resistance to water strong, the resin that film-forming temperature is high, and on the contrary, retention time is short, then selects the resin that resistance to water is strong, film-forming temperature is low for use.
Toner can adopt general organic or inorganic pigment, fineness should be below 1 micron.
In the preparation of the coating of dyed layer, atlapulgite can use or add partly common white soil separately, or mixes use with low-refraction pigment such as silica.Mixed proportion can be any, but with atlapulgite more than 50% for well, adhesive can adopt water permeabilities such as polyacrylate, casein, melmac good, the adhesive that resistance to water is strong.The ratio of atlapulgite and adhesive was better ratio with 7: 1～5: 1 between 8: 1～4: 1.
Example one:
Get atlapulgite 200g, add water 200g, after stirring,, form suspension by reaching 2～5 micron granularities after the sand mill dispersion grinding.With content is 40%, and the about 40 ℃ acrylic acid/styrene copolymer resin 82.5g of film-forming temperature is added in the above-mentioned suspension gradually in stirring down, and making becomes a uniform mixture.
Resulting coating is applied on the paper substrate that is provided with the black bottom, is 12g/m through super-dry, over dry coating weight
2, promptly obtain white water writing paper, obtain the blackness handwriting of contrast distinctness after writing with water-color paintbrush.
Example two:
Get atlapulgite 100g, common commercially available carclazyte (produce in Suzhou, and whiteness is more than 80%) 100g is added to 200g and contains in the aqueous solution of calgon 1.2g, disperses, grinds through sand milling, and making suspension particle is 2～5 μ.The casein solution 165g of 20% solid content is mixed with above-mentioned suspension, obtain white layer coating.This coating is applied on the paper substrate that is provided with red background color layer, gives drying, dry-coated amount is 12g/m
2, promptly obtain white water writing paper, obtain the red writing of contrast distinctness after writing with water-color paintbrush.
