Abstract
The invention discloses a water-based ink composition, which comprises the following raw materials in parts by weight: 20-50 parts of a coloring agent, 15-30 parts of a humectant and 14-65 parts of deionized water. Through increasing the humectant, under the effect of humectant, the evaporation rate of effectual moisture that slows down in the ink, and then makes the ink keep moist under the exposure state for a long time, like this, when the in-service use, can not take place to dry and knot to the ink that exposes on the nib in longer time to ensure that the user keeps good writing smooth and easy degree when writing, with improvement user experience nature.
Description
Technical Field
The invention relates to an ink material, in particular to an aqueous ink composition.
Background
The marking pen is a pen capable of writing marks or signs on one or more materials such as paper, wood, metal, plastic, enamel and the like, and is divided into an oil marking pen and a water marking pen, wherein the water marking pen can write on a smooth object surface or a white board, the water marking pen can be erased by using a rag (white board pen), the oil marking pen is not easy to erase when writing, the marking pen generally comprises a pen shell, a pen head, a pen cap and a cotton core soaked with ink, and the cotton core soaked with the ink is an important component of the marking pen. Ink is used as a writing material, and when the ink is used, the ink on a pen tip is likely to be dried due to long-term non-use, and writing smoothness during rewriting is affected. Therefore, how to design an ink with good moisture retention performance is a technical problem to be solved by the invention.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: provided is an aqueous ink composition which can improve the moisture retention performance of the aqueous ink composition to ensure writing smoothness.
The technical scheme provided by the invention is that the water-based ink composition comprises the following raw materials in parts by weight: 20-50 parts of a coloring agent, 15-30 parts of a humectant and 14-65 parts of deionized water.
Further, the method also comprises the following steps: 0.1-0.5 part of preservative.
Further, the preservative is isothiazolinone or styrene-acrylic isothiazolinone.
Further, the method also comprises the following steps: 0.5-1 part of pH regulator.
Further, the pH regulator is triethanolamine or diethanolamine.
Further, the humectant is one or more of glycerol, propylene glycol, ethylene glycol, diethylene glycol, urea, sorbitol and polyethylene glycol.
Compared with the prior art, the invention has the advantages and positive effects that: according to the water-based ink composition provided by the invention, the humectant is added, so that the evaporation speed of water in the ink is effectively slowed down under the action of the humectant, and the ink can be kept moist for a long time in an exposed state, so that the ink exposed on a pen point can not be dried and knotted for a long time in actual use, a user can be ensured to keep good writing smoothness in writing, and the user experience is improved.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The water-based ink composition of the embodiment comprises the following raw materials in parts by weight: 20-50 parts of a coloring agent, 15-30 parts of a humectant and 14-65 parts of deionized water. Wherein, in order to improve the service life, 0.1 to 0.5 portion of preservative is also included. In addition, in order to adjust the pH value of the aqueous ink composition, a pH adjusting agent is added in an amount of 0.5 to 1 part as required.
For the specific material usage of each component, the colorant may be configured according to the color of the ink, and is not limited or described herein.
One or more of glycerin, propylene glycol, ethylene glycol, diethylene glycol, urea, sorbitol, and polyethylene glycol can be used as the humectant.
Isothiazolinone or benzisothiazolinone can be used as the preservative.
Triethanolamine or diethanolamine can be used as the pH adjuster.
In the actual blending process, the humectant, the preservative, the pH regulator and the deionized water are added into a container according to the formula requirements, and are stirred uniformly. Adding the coloring agent, and continuing stirring until the mixture is uniform. And then, filtering the mixed liquid by a 1-micron PP cotton filter element to obtain the corresponding ink.
Compared with the prior art, the invention has the advantages and positive effects that: according to the water-based ink composition provided by the invention, the humectant is added, so that the evaporation speed of water in the ink is effectively slowed down under the action of the humectant, and the ink can be kept moist for a long time in an exposed state, so that the ink exposed on a pen point can not be dried and knotted for a long time in actual use, a user can be ensured to keep good writing smoothness in writing, and the user experience is improved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
