Porcelain cement synthesis process formula

Abstract

A porcelain cement synthesis process formula is characterized in that porcelain cement is prepared from a labeling adhesive, butadiene rubber, zinc oxide, stearic acid, carbon black N330, carbon black N660, calcium carbonate (light calcium), pine tar and sulfur. The formula has the advantages that the porcelain cement prepared through the formula is uniform in stress, will not fall off, can bear extreme temperature, deforms little at high and low temperature, can prevent bonding portions from cracking, can bear different chemical media, will not seep or leak under acid, alkali, solvent and other conditions, guarantees extremely high medium resistance and is suitable for serving as a binder for alumina ceramic; the surface of alumina ceramic is smooth, so that connection of alumina ceramic cannot be realized through common glue, or alumina ceramic is not firm after connection, the porcelain cement formula solves the technical problem, and the cementation power of the porcelain cement is 20-50 times that of common alumina ceramic glue.

Description

technical field [0001] The invention relates to the technical field of bonding treatment of alumina ceramic sheets, in particular to a formula for synthesizing porcelain glue. Background technique [0002] Alumina ceramics: high alumina content, relatively dense structure, and special properties, so it is called special ceramics. Al2O3. The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions fill two-thirds of the octahedral gaps. This is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point and high Hardness, with excellent wear resistance. The hardness of the ceramic patch is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth, the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the material of the ceramic patch has better performance than other metal materials. It is m...

Problems solved by technology

The hardness of the ceramic patch is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth, the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the material of the ceramic patch has better performance than other metal materials. It is much superior. Ordinary ceramic sheets and rubber cannot be bonded together. Glue is needed for bonding. Ordinary glue cannot be bonded, or it is easy to fall off under the action of external force after bonding.
