Problems solved by technology

However, the thermal conductivity of glass is not as good as that of metal, and it has the most fatal disadvantage: fragile
However, the disadvantage of using ceramics to manufacture mobile phone bodies is that, as a relatively new manufacturing process, its production process has not been perfected, resulting in very low yield and high cost
[0005] Due to the high requirements on the size and surface precision of ceramics, and the large sintering shrinkage rate of ceramics, the accuracy of the size of the ceramic body after sintering cannot be guaranteed, resulting in the need for reprocessing after sintering; in addition, ceramic materials have high hardness, high strength, High brittleness makes it a difficult-to-machine material

Abstract

The invention discloses a ceramic grinding liquid, which is prepared from the following components in percentage by weight: 5 to 25% of lubricant, 10 to 20% of antiwear agent, 5 to 10% rust inhibitor,5 to 15% of wetting agent, 15 to 35% of pH adjusting agent, and 30 to 50% of deionized water. The preparation method of the grinding liquid comprises the following steps: 1) stirring and dissolving the rust inhibitor and the pH adjusting agent uniformly at a temperature of 70 to 90 DEG C, and naturally cooling to obtain a mixed liquid A to be ready for use; 2) stirring and mixing the lubricant and the wetting agent uniformly at room temperature to obtain a mixed liquid B to be ready for use; 3) stirring and mixing the deionized water and the antiwear agent uniformly at normal temperature to obtain a mixed liquid C to be ready for use; 4) stirring and mixing the mixed liquid A, the mixed liquid B and the mixed liquid C uniformly at normal temperature, and filtering to obtain the grinding liquid. The grinding liquid provided by the invention has good lubricity, wettability, and rust resistance, and is particularly suitable for the grinding and processing of mobile phone ceramic materials.

Description

technical field [0001] The present invention relates to a kind of oil for ceramic processing, in particular to a kind of ceramic grinding fluid especially suitable for the processing of ceramic body of mobile phone. In addition, the present invention also relates to a preparation method of said ceramic grinding fluid, which belongs to ceramic processing technology field. Background technique [0002] With the popularity of smart phones and the continuous improvement of manufacturing technology, the material of the mobile phone body is also constantly changing. Since 2012, most mainstream models have adopted the "metal + glass" hybrid panel back cover. Since then, metal has become the standard configuration of high-end smartphone materials. Moreover, due to the light and thin appearance of metal, good thermal conductivity and strong hardness, metal has become the most common casing material at present. However, metal has electromagnetic shielding properties, and its complic...
