Problems solved by technology

[0002] The existing ink fountain rollers are all made of steel, the surface hardness is not strong, and the wear resistance is poor. During the printing process, the surface roughness of the ink fountain rollers will decrease significantly, thus affecting the printing effect. Weakly alkaline or weakly acidic substances, in contact with the steel ink fountain roller, the ink fountain roller is easy to corrode, and will also affect the printing effect. Therefore, there is an urgent need for a wear-resistant and corrosion-resistant ink fountain roller
At present, the application of the spraying process to the ink fountain roller on printing has not yet been realized.

Abstract

The invention discloses a method for preparing a ceramic ink fountain roller special for printing. The method comprises the following steps of: putting 70 to 80 parts of tungsten carbide ceramic, 4 to 8 parts of kaolin and 4 to 8 parts of clay into a ball mill, grinding for 3 to 5 hours, grinding 3 to 7 parts of calcium carbonate, 2 to 6 parts of talcpowder and 2 to 6 parts of potassium feldspar, drying, forming, sintering, cooling, and sieving to obtain ceramic powder master batch; putting the ceramic powder master batch into an evaporator, putting an ink fountain roller on a workpiece frame, vacuumizing a spraying chamber, driving the ink fountain roller to rotate by using the workpiece frame, opening a nitrogen cylinder, spraying nitrogen on the ink fountain roller by using a spray gun, and performing surface treatment on the ink fountain roller; vacuumizing the spraying chamber, starting the evaporator, melting and evaporating the ceramic powder master batch, spraying the evaporated ceramic powder on the ink fountain roller by using the spray gun, keeping for a certain period of time, opening the spraying chamber, and cooling at normal temperature to obtain the ceramic ink fountain roller special for printing. The method is simple, and the prepared ceramic ink fountain roller can meet the requirement of printability.
