The invention discloses a special
colored hot-press
label of a resin
grinding wheel. The special
colored hot-press
label comprises a black
paperboard or a
copper printing paper substrate, a bottom layer, a pattered oil layer and a protective layer, wherein the bottom layer, the pattered ink layer and the protective layer are offset-printed on the substrate. Aiming at realizing small color change amplitude after a finished
product label and the
grinding wheel are sintered and vulcanized together, ink for the pattered ink layer is scientifically prepared from materials, such as
polydimethylsiloxane phenolic resin, a
chemical corrosion resisting agent, an anti-friction agent, tung oil, organic
pigment, and the like, crude ink is modified, the high-temperature
softening point of the ink layeris improved, the
adhesive film
hardness of the surface of the ink layer is increased, and an
adhesive film gap on the surface of the ink layer is sealed. The special
colored hot-press
label has the advantages that: a brand name and various technical data of the
grinding wheel are printed with various colors of ink by utilizing the appropriate substrate and then die-
cut and formed, and directly hot-pressed on the surface of the substrate in the production process of the
grinding wheel, and the
grinding wheel is discharged from a furnace after dried in a high-temperature vulcanizing
kiln for 30h at 186 DEG C, therefore, the mark of the label is very distinct, not powdered and obscure, and the color change amplitude is less than 10 percent.
