Problems solved by technology

However, due to the inherent unevenness of the base material obtained by grinding natural mica, such as steps, and only part of the base material can be removed, it is impossible to obtain a flat air layer, but only irregularly shaped cavities to a certain extent. structure, so that the effect of the air layer as a layer structure cannot be fully exerted, which affects the display and play of special color effects

Embodiment 1

[0140] The core material of the pigment in this embodiment is a single layer of silicon dioxide, and the outer coating layer is titanium dioxide.

[0141] Use vacuum sputtering technology to deposit a layer of zinc sulfide of about 10nm on the substrate glass plate, followed by deposition of silicon dioxide until it reaches 170nm, then deposit about 10nm of zinc sulfide, and then continue to deposit silicon dioxide 170nm, repeat Repeat the above process for 10 cycles, and the total thickness reaches about 2um. Afterwards, the material was immersed in hydrochloric acid (concentration: 35%) for about 30 minutes to remove zinc sulfide and obtain a silicon dioxide sheet with a very high surface smoothness and a thickness of 170 nm. After subsequent washing and classification, the particle size distribution was 20. - 100um core material precursor, used as a substrate for subsequent cladding, with a thickness of 170±2nm.

[0142] Then 40 g of the core material precursor was dispers...

Embodiment 2

[0145] The core material of the pigment in this embodiment is a single layer of silicon dioxide, and the outer coating layer is a mixed coating layer of titanium dioxide and ferric oxide.

[0146] Use vacuum sputtering technology to deposit an organic peelable isolation layer of about 10nm on the base glass plate first, then deposit silicon dioxide until it reaches 80nm, then deposit an organic peelable isolation layer of about 10nm, and then continue to deposit two layers. Silicon oxide 80nm, repeat the above process repeatedly, repeat 20 cycles, the total thickness reaches about 2um. Then immerse the material in a release agent to remove the peelable isolation layer to obtain a silicon dioxide sheet with a very high surface smoothness and a thickness of 80nm. After subsequent washing and classification, a core material with a particle size distribution of 10-60um is obtained. The precursor is used as the substrate for subsequent wet chemical coating, and its thickness is 80±...

Embodiment 3

[0150] The core material of the pigment in this embodiment is a single layer of aluminum oxide, and the outer cladding layer is iron oxide.

[0151] Use vacuum sputtering technology to deposit an organic strippable isolation layer of about 10nm on the substrate glass plate, then deposit aluminum oxide until it reaches 100nm, then deposit a strippable isolation layer of about 10nm, and then continue to deposit Al2O3 100nm, repeat the above process repeatedly, repeat 20 cycles, the total thickness reaches about 2um. Then immerse the material in an organic release agent to remove the peelable isolation layer to obtain aluminum oxide with a high surface smoothness and a thickness of 100nm. After subsequent washing and grading treatment, a core with a particle size distribution of 40-80um is obtained. The material precursor is used as the substrate for subsequent wet chemical coating, and its thickness is 100±1.5nm.

[0152] Then disperse 40g of the substrate in 1L of water, heat ...

The pigment disclosed by the invention can be used in paints, inks, cosmetics, and makeup.

Description

[0001] This application claims the priority right of the Chinese invention patent application No. 201810698484.X (the name of the invention is a pigment with high brightness, color purity and hiding effect and its preparation method) submitted on June 29, 2018. The entirety of the priority document The content is incorporated herein by reference. technical field [0002] The present invention relates to a kind of pigment, more specifically, relates to a kind of high-brightness pigment and its preparation method and application. Background technique [0003] Pearlescent pigments have rich and colorful colors, which can meet the application requirements of various industries. With the further expansion of the scope of use and the further expansion of the use occasions, more stringent requirements are put forward for pearlescent pigments. For ordinary pearlescent pigments, the general brightness and hiding power are two contradictory properties. If the covering power of the po...
