Roll core for winding tight-winding type polishing wheel and curing process of tight-winding type polishing wheel

The invention discloses a winding core for winding a tight-winding type polishing wheel and a curing process of the tight-winding type polishing wheel, the winding core is used for winding a coated non-woven fabric base material, the winding core is of a hollow tubular structure formed by winding glass fiber mesh cloth impregnated with thermosetting resin, and the porosity of the winding core is 30%-70%. One end of the roll core is closed, and the other end is connected with a negative-pressure exhaust pipe. The invention further provides a curing process applying the roll core and a slurry system coated with non-woven fabric, the problem that a large amount of organic solvent is used as a diluent in an existing tight rolling wheel process, and consequently a large amount of organic solvent is discharged is solved, and a polishing wheel product is excellent in wear resistance; meanwhile, according to the production method, the required curing process time is shortened to one third of the original time, and th
