Description

Water-based ink with three-dimensional effect and preparation method thereof

Technical Field

The invention belongs to the field of water-based ink, and particularly relates to water-based ink with a three-dimensional effect and a preparation method thereof.

Background

The stereo ink is one new kind of functional ink, and it changes the planar visual effect of available writing tool and has one stereo structure and may be written with simple ball pen. The method overcomes the difficulty of directly writing viscous ink, can easily realize the problem of dispersion stability of effect pigments such as pearlescent and the like which are difficult to stabilize by utilizing high system viscosity, and has wide adaptability and abundant variability of colors.

At present, domestic similar products have fewer varieties, a high solid content system is not researched much, and when the ink is used for writing in a writing tool, the ink is difficult to write, the drying time is long, and the drying time is inconsistent inside and outside, so that the further development of the three-dimensional ink is influenced. In the aspect of environmental protection, the writing function of the product is generally focused, and the formula improvement from the aspects of environmental protection and safety is less active.

Disclosure of Invention

The invention aims to solve the technical problems that the viscosity of the existing three-dimensional ink system is not easy to control, the ink is difficult to write and the like.

The invention provides water-based ink with a three-dimensional effect, which comprises the following raw materials in percentage by mass: 1-15% of fluorescent pigment, 40-80% of resin, 0.5-3% of metal powder pigment, 0.2-0.5% of antirust agent, 1-5% of lubricant, 5-15% of humectant, 0.2-0.5% of pH regulator, 5-10% of stabilizer and the balance of deionized water.

The fluorescent pigment is one or more of anthrone, triarylmethane, phthalocyanine pigment or dye. When the pigment concentration in the ink exceeds 15%, the viscosity and fluidity of the ink are adversely affected. When the concentration of the pigment in the ink is less than 1%, it is difficult to obtain the intended color effect.

The resin is obtained by compounding acrylic acid and EVA in a mass ratio of 1: 1-1: 4. The resin is preferably present in an amount of 60-80%. When the concentration of the resin in the ink exceeds 80%, the addition and matching of other functional materials cannot be guaranteed. When the concentration of the resin in the ink is less than 40%, it is difficult to obtain the intended cubic effect. The use amount of EVA is too much, which affects the three-dimensional effect and the drying performance, and the use amount of EVA is less which affects the writing and the state of ink in the pen.

The humectant is one or more of decaglycerol, glycerol, propylene glycol, polyethylene glycol and polypropylene glycol. The preferred content is 5-15%. When the concentration of the humectant in the ink exceeds 20%, the drying and steric functionality of the water-soluble resin will be significantly reduced, and drying and adhesion will be affected. When the concentration of the humectant in the ink is less than 5%, writing with the pen is adversely affected.

The metal powder pigment is a color aluminum powder pigment. The metal powder pigment is preferably present in an amount of 1-2%. When the concentration of the metal powder pigment is higher than 3%, the increased solid concentration will adversely affect the viscosity and flowability of the composition. On the other hand, when the concentration of the metal powder pigment is less than 0.5% by weight, the characteristic glittering effect is reduced.

The lubricant is one or more of polyoxyethylene alkali metal salt, dicarboxylic acid amide, phosphate ester, oleoyl sarcosinate and potassium oleate.

The wetting agent is one or more of decaglycerol, glycerol, propylene glycol and polypropylene glycol.

The pH regulator is ammonia water.

The stabilizer is one or more of polyethylene wax, fumed silica and deca-polyglycerol ester.

The invention provides a preparation method of water-based ink with a three-dimensional effect, which comprises the following steps:

according to the proportion, the pigment, the metal powder pigment and deionized water are mixed and stirred, then water-soluble resin is added and stirred, then water-soluble organic solvent, preservative, lubricant, wetting agent and stabilizer are added and stirred under the dry condition, and finally pH value is adjusted by adopting pH regulator, so that the water-based ink is obtained.

Advantageous effects

The writing pen still presents a full three-dimensional structure after being dried, has better visual effect compared with the common writing pen, is rich and changeable in color, can be written on a series of base materials such as white paper, black paperboard, glass, metal and the like, and has good adhesive force and wide application. At present, the environmental protection and the safety are more and more emphasized, and the decaglycerol ester which are friendly to human and environment are adopted, so that the zero addition of the existing non-environmental protection preservative is realized.
