Problems solved by technology

[0003] At present, there are already some nano-color paste products on the market, such as the invention patent with the publication number CN101629038A, "A production method of water-based nano-color paste for digital inkjet and a container with an ultrasonic generating device", which proposes A nano-color paste with a material particle size fineness of 150-250nm, the invention patent with the publication number CN101760088A, "Nano-modified environment-friendly iron oxide machine color paste and preparation method", proposes a particle size distribution reaching A color paste with D99 ​​less than 1um, the invention patent with publication number CN101747687A, "Sub-nanometer golden water-based color paste for hydrophilic coatings and its preparation method", proposes a color paste with D99 ​​less than 1.2um, other similar patents Among them, the particle size that the color paste can achieve is basically in the same range. From the above patents, we can see that the particle size of these "nano color paste" or "sub-nanometer color paste" is actually at a sub-nanometer level, not Real nano-color pastes, these color pastes have large particle sizes and uneven distribution. In the actual use process, it is not only difficult to show good visual effects, but also cannot guarantee color quality. At the same time, these color pastes are not water-based and cannot Reach environmental protection standards, so these color pastes still cannot be widely used

Abstract

The invention relates to a preparation method of environment-friendly nanometer water-based color paste, which comprises the following steps: 1) uniformly mixing pigment, a surfactant and a solvent toobtain a mixed solution A; 2) adding a grinding medium into the mixed solution A to obtain a blend, and performing dispersing and grinding; 3) performing grinding medium separation and filtration onthe dispersed and ground blend to obtain a mixed solution B; 4) performing grain size screening and filtration on the mixed solution B to obtain the water-based color paste which has small color pastegrain size, uniform grain size distribution, high environmental protection level and stable state.

Description

technical field [0001] The invention relates to the field of water-based color paste, in particular to a preparation method of nanometer water-based inkjet color paste. Background technique [0002] With the improvement of people's quality of life, the requirements for the appearance and color of daily necessities and living environment are also rising, so the research and development of the visual effect and color quality of products are getting more and more in-depth. As we all know, pigment is a kind of coloring substance. Pigment has high light fastness, weather fastness and solvent resistance. The color of pigment is bright and bright. Wide range of applications. As a colorant, the pigment should be uniformly and stably dispersed in the medium to prepare a color paste. During the preparation process, it is necessary to ensure that the particle size of the color paste reaches the minimum value and the particle size distribution is uniform, so that the fusion of the colo...
