The invention discloses a method for forming a hot melt super coating on a coated abrasive tool, which is to heat and melt a material and coat the molten material by a roller coating equipment onto the surface of the coated abrasive tool, and is characterized in that: the material is stearate, or a mixture of stearate and paraffin wax or a mixture of stearate, paraffin wax and antioxidant or mixture of stearate, paraffin wax, antioxidant and EVA resin or PP resin and is heated and melted at the temperature of 110 to 160 DEG C; the molten stearate or mixtures of the stearate is coated on the surface of abrasive paper or abrasive cloth by hot melt coating equipment; and naturally cooling, drying and obtaining hot melt coating products. The hot melt coating has the advantages of no toxicity, no solvent, low cost, short production route and the like compared with water soluble or solvent coating, and the obtained abrasive tool has a more compact surface structure and has the advantages of blockage prevention, burn prevention and the like in use.
