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.

Abstract

The invention relates to a super-concentrated high-solid nano-yellow paste and its preparation method and application. The yellow paste contains the following components in weight percentage: 40-50% of inorganic and organic mixed yellow pigments, 30-40% of liquid oil, 10-20% dispersant, 0.5-1% anti-aging additive, 0.5-1% anti-sedimentation additive. Compared with the existing technology, the nano-yellow paste has an average particle size of 1 micron and good compatibility with light-curable resins. It can be used for 3D printing of LCD\SLA\DLP, and is used to make high-strength, high-temperature-resistant , waterproof and other industrial materials to ensure that the printed finished product has high color brilliance, is not easy to precipitate, is not affected by light and printing temperature, and has high precision, which is conducive to the development of 3D colored materials. Sunlight production is in line with the economic development trend of energy conservation and environmental protection. It is also beneficial to the company's needs for safety and health protection of 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...
