Processing technology for rubber coating of high-precision steel ring

The invention discloses a processing technology for rubber coating of a high-precision steel ring, and relates to the technical field of rubber coating processing.The processing technology for rubber coating of the high-precision steel ring specifically comprises the following steps that S1, the steel ring needing rubber coating is taken, cleaned with an organic solvent and dried for standby application; s2, the surface of the cleaned steel ring is subjected to micro sand blasting treatment and then coated with a primer solution, the temperature is increased to 80-85 DEG C after heating curing, heat preservation is conducted for 1-2 h, and a primer layer is obtained; s3, the steel ring treated in the step S2 is put into a mold, then glue is injected to the outer surface of the steel ring, and a glue coating layer is formed on the surface of the steel ring after hot pressing treatment; and S4, taking out the finished product from the mold to obtain the product. According to the processing technology for the hi
