Embodiment 1

[0047] According to a kind of environment-friendly water-based nano color paste proposed by the present invention and preparation method thereof, at first, prepare each component of following weight ratio, altogether 20Kg:

[0048]

[0049] Surplus is water, and in the present embodiment, what dispersant adopts is Germany Digao 740 water-based dispersant, what sterilant adopts is Dow 7287, and the kind of sterilant is a lot, in the product of the present invention, basically as long as can Satisfy the effect of sterilization, and at the same time, non-toxic or low-toxic sterilizers to the human body can be used. The polyamide wax is Changxing Xiehe, and the models that can be used for water-based pigments can be domestic or imported.

[0050] Specifically, the proportion of water-based pigments in the environmentally friendly water-based nano-color paste accounts for 15-30%, which is higher than the traditional 15%, so the color is brighter when printing and saves costs; amo...

Embodiment 2

[0074] The preparation method of embodiment 2 is identical with embodiment 1, and difference is only in the weight ratio of each component, totally 20Kg, as follows:

[0075]

[0076] The d(0.1) is 0.035um, the d(0.5) is 0.060um, and the d(0.9) is 0.093um as measured by a Malvern particle size analyzer (model: MASTERSIZER 2000).

[0077] Compared with embodiment 1, embodiment 2 increases the proportion of pigment, and the beneficial effects are basically the same.

Embodiment 3

[0079] The preparation method of embodiment 3 is the same as embodiment 1, and the difference is only in the weight ratio of each component, as follows:

[0080]

[0081] The d(0.1) is 0.038um, the d(0.5) is 0.066um, and the d(0.9) is 0.098um as measured by a Malvern particle size analyzer (model: MASTERSIZER 2000).

[0082] Compared with embodiment 1, embodiment 3 further increases the proportion of pigment, and the beneficial effect is basically the same.

[0083] Implementation 1, Example 2, and Example 3 can be seen after being detected by the Malvern particle size analyzer, the product obtained by the method and formula ratio disclosed by the present invention has reached the nanometer level, the performance is more prominent, and the scope of application is wider.

[0084] Further, after verifying the particle size of the product, the stability of the product was also tested, and the obtained product was stored for 12 months before testing. The particle size of the pr...

Abstract

The invention discloses environment-friendly water-based nano color paste. The color paste is prepared from, by weight, 28-30 parts of a dispersing agent, 1-4 parts of a sterilizing agent, 1-2 parts of a defoaming agent, 30-60 parts of water-based pigment, 1-3 parts of polyamide wax, and the balance of water. The invention further discloses a preparation method of the environment-friendly water-based nano color paste. The preparation method of the environment-friendly water-based nano color paste is characterized by comprising the following steps: (S1) coarsely grinding: adding the raw materials and water, mixing and stirring to obtain a mixed color paste, grinding the mixed color paste until the particle size of the mixed color paste is not greater than 3 [mu]m, washing with water accounting for 10-15% of the total amount of the water, uniformly stirring, and performing coarse filtration; (S2) finely grinding: continuously dispersing and grinding the mixed color paste subjected to coarse grinding, and stopping dispersing and grinding until the measured particle size distribution of the mixed color paste reaches the standard; and (S3) washing and stirring: adding residual water forwashing, and uniformly stirring to obtain the color paste. The color paste has the advantages of high stability, long shelf life and environmental friendliness.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to an environment-friendly water-based nano color paste, especially an environment-friendly water-based nano-color paste and a preparation method thereof. Background technique [0002] Inkjet printing is a non-contact printing technology. The pattern is formed by mixing tiny ink droplets of different colors directly on the surface of the equipment. Therefore, the formation, shape and size of ink droplets are very important to the quality of inkjet printing patterns. At present, as the droplet ejection volume of commercial printing inkjet heads can be as small as 1pL, this puts forward higher requirements for the development and production of inkjet colorants. If the particles of inkjet colorants are too large, It is easy to block the nozzle. At present, there are some nano-color paste products on the market, and there are also some nano-color paste patents on the Internet, such a...
