However, a part of the mortar will remain on the surface of the process equipment during the recycling process, and the surface of this type of process equipment is generally a material with high surface energy such as metal, organic matter or glass, so once the mortar remains on the surface, it will be difficult to remove
[0003] At present, in order to remove the mortar remaining on the surface of the process equipment during the process implementation, the auxiliary solvent is usually used for cleaning, but the auxiliary solvent after cleaning will enter the recycled mortar, resulting in a decrease in the mortar concentration. In order to ensure the quality of the workpiece , it is necessary to continuously add new mortar in the process of process implementation to ensure the mortar concentration, thus reducing the use efficiency of mortar, causing waste of mortar, and increasing process cost

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0020] Taking metal as an example, when the surface material of the process equipment is a metal material, when the mortar resides on the surface of the process equipment, the contact angle between the mortar and the metal surface of the process equipment is as figure 1 shown, from figure 1 It can be seen that the contact angle between the mortar and the metal surface is an obtuse angle, so the mortar can easily reside on the metal surface to form residues. In order to reduce the contact angle between the mortar and the metal surface, so that the mortar is not easy to reside on the metal surface. The embodiment of the present invention provides a super-oleophobic organic coating for coating on the technical surface of process equipment and its preparation method, which is exp...

Abstract
The embodiment of the present invention discloses a super-oleophobic organic coating and a preparation method thereof; the raw material of the super-oleophobic organic coating includes the following components in parts by mass: 3 parts of silicon dioxide nanoparticles, 1 part of silicon carbide nanoparticles, organic 10 parts of solution, 1 part of polydimethylsiloxane, 10 parts of curing agent, and 120 to 240 parts of 98% ethanol solution by mass; wherein, the particle size of the silicon dioxide nanoparticles is smaller than that of the silicon carbide The particle size of the nanoparticles.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of organic coatings, in particular to a super-oleophobic organic coating and a preparation method thereof. Background technique [0002] In the field of silicon wafer manufacturing, a large amount of mortar is used in the multi-wire cutting process and the double-side grinding process in order to process and cool the workpiece. This mortar is composed of particles such as silicon carbide, aluminum oxide, silicon dioxide, and oily or water-based polymers and dispersants, and is recycled during the process. However, a part of the mortar will remain on the surface of the process equipment during the recycling process, and the surface of this type of process equipment is generally a material with high surface energy such as metal, organic matter or glass, so once the mortar remains on the surface, it will be difficult to remove . [0003] At present, in order to remove the mortar rema...
