preparation example Construction

[0030] The specific preparation process is as follows: first, mix and stir carmine and allura red according to the proportion of components; then, put the mixed powder into a vessel, add a solvent to the vessel for preparation, the solvent is water or alcohol, and mix well; Then, add the vessel to the magnet and put it on the magnetic stirrer. The magnetic stirrer has a heating temperature control device. Through heating and magnet rotation and stirring, the heating temperature is 40-50°C to dissolve the powder evenly and form a coating. solution.

[0031] In the specific application of the coating liquid that promotes the absorption ability of infrared laser to ceramics, the alumina substrate is placed flat on the carrier with adsorption holes, the ceramic plate is fixed on it, and the surface of the ceramic plate is coated with a dust-free cloth dipped in the coating liquid. cover.

Embodiment 1

[0033] First, mix 24% of carmine and 1% of allura red according to the distribution ratio of the components and mix and stir evenly; then, put the mixed powder into the container, add 75% water to the container for preparation, and mix evenly; then, put the container into the magnetic Put it on the magnetic stirrer. The magnetic stirrer has a heating temperature control device. The heating temperature is 40-50°C through heating and magnetic rotation stirring, so that the solid powder can be better and uniformly dissolved to form a coating solution.

Embodiment 2

[0035] First, mix 20% of carmine and 5% of allura red according to the distribution ratio of the components and mix and stir evenly; then, put the mixed powder into the beaker, add 75% alcohol to the beaker for preparation, and mix well; then, put the beaker into the magnetic Put it on the magnetic stirrer. The magnetic stirrer has a heating temperature control device. The heating temperature is 40-50°C through heating and magnetic rotation stirring, so that the solid powder can be better and uniformly dissolved to form a coating solution.

Abstract

The present invention relates to a coating liquid for promoting infrared laser absorption capacity on ceramic, a preparation method and application thereof. The coating liquid comprises 20-40% of carmine, 1-5% of Allura red and 55-75% of a solvent. The preparation is as below: first uniformly mixing carmine and Allura red; adding the mixed powder into a container, adding a solvent for formulation, and evenly mixing; adding magneton into the container, placing the container on a magnetic stirrer, uniformly dissolving the powder by heating and magneton rotation stirring to form the coating liquid. The surface of a ceramic plate is coated with the coating liquid by a dust-free cloth. The coating liquid can be applied to ceramic laser processing to promote the infrared laser absorption capacity on ceramic, reaches high absorption rate of near infrared wave and high efficiency, and avoids the light breakage and line leakage phenomena.

Description

technical field [0001] The invention relates to a coating solution for promoting the absorption ability of infrared laser to ceramics and its preparation method and application, which is suitable for laser marking and cutting of ceramics (alumina, zirconia, aluminum nitride), and can also be used as other materials for processing when used as a protective agent. Background technique [0002] As a new type of processing method, laser gradually replaces some traditional mechanical processing methods. The processing direction extends to all fields of the whole society, and develops towards a high-precision processing mode, which not only satisfies extensive processing, but also takes into account fine processing. [0003] Inside the laser, one photon excites other photons, so that a large number of photons are emitted together in the form of beams, and converged into a small spot by focusing, which can interact with materials without direct contact. When the laser beam is tran...
