Problems solved by technology

This penetration phenomenon will affect or violate the expression of the artist's creative ideas in the work; in addition, the chemical stability of the dye is poor, and the color will change and fade under the action of factors such as light, oxygen in the air, and humidity in the air, and the work will lose its original color. Some artistic charm and value, the preservation life is also greatly shortened
[0004] Domestically produced nano-pigments are still relatively expensive, and using all nano-pigments to make watercolor paints for art will lead to an increase in product costs

Embodiment 1

[0033] A kind of manufacture method of the watercolor pigment for art that contains nano pigment of the present invention adopts the following process steps: its formula ratio is counted by mass parts:

[0034] Sprinkle 4.0 parts of gum arabic into 14.5 parts of distilled water, swell for 6 hours, heat to 80°C, and heat for 30 minutes; add 50.0 parts of water-soluble starch and 6.0 parts of hydrated silicon dioxide to make an adhesive glue liquid. Add 4.0 parts of glycerin, 0.4 parts of sodium benzoate, 3.5 parts of nano-titanium dioxide for the nano-pigment (slurry), and 1.5 parts of sodium hexametaphosphate into the above-mentioned adhesive glue and stir evenly to form a mixture. Add 15 parts of pigment (powder) lithopone and 6.0 parts of titanium dioxide to the above mixture, and then stir for 1 hour, then add 2.0 parts of aluminum silicate, and stir evenly to form a color paste. The above-mentioned color paste material is added in the hopper of the three-roll mill, and gr...

Embodiment 2

[0036] A kind of manufacture method of the watercolor pigment for art that contains nano pigment of the present invention adopts the following process steps: its formula ratio is counted by mass parts:

[0037] Sprinkle 4.2 parts of gum arabic into 13.0 parts of distilled water, swell for 8 hours, heat to 88°C, and heat for 45 minutes; add 52.0 parts of water-soluble starch and 7.0 parts of hydrated silicon dioxide to make an adhesive glue liquid. Add 3.5 parts of glycerin, 0.35 parts of sodium benzoate, 1.5 parts of nano-pigment (slurry) nano-titanium dioxide, 2.0 parts of nano-calcium carbonate, and 1.0 part of sodium hexametaphosphate into the above-mentioned adhesive glue and stir to form a mixture. Add 15 parts of pigment (powder) lithopone to the above mixture, stir for another 1.5 hours, then add 1.8 parts of aluminum silicate, and stir evenly to form a color paste. The above-mentioned color paste material is added in the hopper of the three-roll mill, and ground by th...

Embodiment 3

[0038] Embodiment three: a kind of manufacture method of the watercolor pigment for art that contains nano pigment of the present invention adopts following processing steps: its formula ratio is counted in parts by mass:

[0039]Sprinkle 3.5 parts of gum arabic into 18.0 parts of distilled water, swell for 10 hours, heat to 90°C, and heat for 60 minutes; add 55 parts of water-soluble starch and 8.0 parts of hydrated silicon dioxide to make an adhesive glue liquid. Add 3.0 parts of glycerin, 0.3 parts of sodium benzoate, 1.5 parts of nano-iron oxide for nano pigment (slurry), and 1.2 parts of sodium hexametaphosphate into the above-mentioned adhesive glue and stir evenly to form a mixture. Add 8.0 parts of pigment (powder) iron oxide to the above mixture, stir for another 2 hours, then add 2.5 parts of aluminum silicate, and stir evenly to form a color paste. The above-mentioned color paste material is added in the hopper of the three-roll mill, and ground by the three-roll m...

Abstract

The invention relates to art watercolor with nano-pigment and the preparation method, belonging to technical field of painting things, which is characterized in that the gum arabic is put into distilled water and then added in water soluble starch and hydrated silicon dioxide to make the bond glue. Then the bond glue is added in glycerin, sodium benzoate, nano-pigment (paste) and sodium hexametaphosphate to blend evenly. Next the pigment (powder) and the aluminum silicate are added in and then blended evenly to make rough sizing agent. The rough sizing agent is put into the hopper of a three-roller muller to grind and the product can be obtained after grinding. The preparation method utilizes a few nano-pigments to replace parts of common pigment materials. The product made has the advantages of good service performance, bright color, good weather resisting property and strong chemical durability.

Description

technical field [0001] The invention relates to a watercolor paint for art containing nano pigments and a manufacturing method thereof, specifically belonging to the technical field of painting supplies. Background technique [0002] In the prior art, in the previous art watercolor pigment products, because the pigment raw materials used are insoluble or insoluble, its particle size is relatively large, generally large particles or small agglomerates of 20-100 microns. Although the secondary polymerized ordinary pigment particles will be re-dispersed after being ground with a binder when preparing the product, the efficiency and effect are not ideal, and the particle size of the pigment particles in the final product still reaches 10-40um, causing the traditional The finished watercolor pigments for art use are relatively large due to the relatively large pigment particles dispersed in the matrix, resulting in dull painting color, poor saturation, rough texture of the pictur...
