Embodiment 1

[0022] A super-concentrated high-solid nano-yellow slurry, the specific composition of the yellow slurry is shown in Table 1. The super-concentrated high-solid nano-yellow paste is prepared by the following preparation method: the inorganic and organic composite yellow pigments, anti-aging additives, anti-sedimentation additives, dispersants and liquid oil are formulated according to the weight percentage of Example 1 in Table 1. Specific weighing, adding to the container one by one, using a high-speed disperser for mixing and dispersing, the rotating speed is 1500r / min, and the mixing time is 60min. And ball mill dispersion, in which the high-speed shear dispersion cycle is 3 times, and the particle size of the mixture is detected. When the particle size is less than 900nm, the super-concentrated high-solid nano-yellow slurry can be obtained.

[0023] The prepared nano-yellow paste was subjected to a performance test, and the test results are shown in Table 2.

Embodiment 2

[0025] A super-concentrated high-solid nano-yellow slurry, the specific composition of the yellow slurry is shown in Table 1. The super-concentrated high-solid nano-yellow paste is prepared by the following preparation method: the inorganic and organic composite yellow pigments, anti-aging additives, anti-sedimentation additives, dispersants and liquid oil are formulated according to the weight percentage of Example 2 in Table 1. Specific weighing, adding to the container one by one, using a high-speed disperser for mixing and dispersing, the rotating speed is 1400r / min, and the mixing time is 50min. And ball mill dispersion, in which the high-speed shear dispersion cycle is 6 times, and the particle size of the mixture is detected. When the particle size is less than 900nm, the ultra-concentrated high-solid nano-yellow slurry can be obtained.

Embodiment 3

[0027] A super-concentrated high-solid nano-yellow slurry, the specific composition of the yellow slurry is shown in Table 1. The super-concentrated high-solid nano-yellow paste is prepared by the following preparation method: the inorganic and organic composite yellow pigments, anti-aging additives, anti-sedimentation additives, dispersants and liquid oil are formulated according to the weight percentage of Example 2 in Table 1.

Abstract

The invention relates to super-concentrated high-solid nanometer yellow pigment paste, a preparation method and applications thereof, wherein the yellow pigment paste comprises, by weight, 40-50% of an inorganic and organic mixed yellow pigment, 30-40% of liquid oil, 10-20% of a dispersing agent, 0.5-1% of an anti-aging auxiliary agent and 0.5-1% of an anti-precipitation auxiliary agent. Comparedwith the nanometer yellow pigment paste in the prior art, the nanometer yellow pigment paste of the invention has an average particle fineness of 1 [mu]m, has good compatibility with light-cured resins, can be used for 3D printing of LCD\SLA\DLP, is used for manufacturing high-strength, high-temperature-resistant, waterproof and other industrial materials, can ensure the printed finished product is high in color brightness, not prone to precipitation, free of influences of illumination and printing temperature and extremely high in precision, and is beneficial to development of 3D colored materials; and the production process is simple, does not require sunlight shielding production, meets the economic development trend of energy conservation and environmental protection, and meets the safety and health guarantee requirements of enterprises on production operators.

Description

technical field [0001] The invention relates to the technical field of new material coloring, in particular to a super-concentrated high-solid nano-yellow paste and its preparation method and application. Background technique [0002] 3D printing technology, also known as rapid prototyping technology, referred to as R P or R P M technology (Rapid Prototyping Manufacturing), is a rapid design and prototyping technology developed in the late 1980s. Stereolithography is currently the most precise rapid prototyping technology. It has the advantages of high production efficiency and high material utilization, and can quickly and accurately manufacture complex-shaped objects. Its working principle is: a laser beam with a certain wavelength and intensity scans the light-curing resin point by point according to the shape of each layered section of the model. A solidified thin section, after scanning one layer, the workbench moves a layer-thick distance, so that each layer is scanne...
