preparation Embodiment 1

[0061] Add 80.35 grams of water, 10 grams of glycerin, 5 grams of pyrrolidone carboxylic acid, 0.5 grams of TW-20, and 0.3 grams of KathonLXE agent into the reaction kettle with paddle stirring, and stir evenly; then slowly add 3.85 grams of Acid blue 9, after adding, increase the speed and stir evenly. Finally, the finished product is obtained by filtering.

preparation Embodiment 2

[0063] Add 82.2 grams of water, 10 grams of glycerin, 5 grams of amino acids, 0.5 grams of TW-20, and 0.3 grams of Proxel XL2 agent into the reaction kettle with paddle stirring, and stir well; then slowly add 2.0 grams of acid under low-speed stirring Red 18, after adding, increase the speed and stir evenly. Finally, the finished product is obtained by filtering.

preparation Embodiment 3

[0065] Add 82.7 grams of water, 10 grams of glycerin, 5 grams of sodium lactate, 0.5 grams of TW-20, and 0.3 grams of Kathon LXE agent into the reaction kettle with paddle stirring, and stir evenly; then slowly add 1.5 grams of acid Yellow 23, after adding, increase the speed and stir evenly. Finally, the finished product is obtained by filtering.

[0066] performance example

[0067] Make the maca pen with the ink of above-mentioned embodiment 1~3, under 25 ℃, under the condition of humidity 50%-70%, the nib is uncapped more than three months, and nib keeps not dry, and writes in ink normally. Commercially available inks were left under these test conditions for three days, and the nibs dried out and could not be written on.

Abstract

The invention provides a dye-type non-dry watercolor ink composition, which comprises the following components in part by weight: (a) 0.5 to 7.0 parts of dye, (b) 10.0 to 15.0 parts of moisturizing agent, (c) 0.05 to 0.3 part of antiseptic and mildew-proof agent, (d) 0.1 to 0.5 part of auxiliary agent and (e) 77.2 to 84.35 parts of water, wherein the components (a) to (e) account for 95 to 100 percent of the total weight of the composition; the (b) moisturizing agent is a compound moisturizing agent consisting of two moisturizing agents, wherein the first moisturizing agent is may be one or more of glycerol, ethylene glycol, propylene glycol, polyethylene glycol, diethylene glycol, triethylene glycol and sorbitol; the second moisturizing agent is selected from one or more of sodium lactate, hyaluronic acid, pyrrolidone carboxylic acid, natural moisturizing factor (NMF) and amino acid; and the weight ratio of the first moisturizing agent to the second moisturizing agent is (2-3): 1.

Description

technical field [0001] The invention relates to an ink and a manufacturing method thereof, in particular to a dye type non-drying watercolor ink and a manufacturing method thereof. Background technique [0002] Watercolor ink is a kind of low-viscosity color ink for children's paintbrush. It has the characteristics of sufficient moisture, bright colors, light and bright. Watercolor pens are mainly used by young children. They often forget to cover the pen cap during the use of the pen, so it is easy to cause the tip of the pen to dry up and cannot be used. The main reason for this problem is that ordinary watercolor inks have poor moisture retention. [0003] To sum up, this area lacks the dye type non-drying watercolor ink that the nib does not dry for a long time under the state of opening the cap. Therefore, there is an urgent need in this area to develop a dye-type non-drying watercolor ink that is permanently non-drying and has a good level of normal marking under the...
