Special colored hot-press label of resin grinding wheel

Abstract

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.

Description

Technical field [0001] The invention relates to a label, in particular to a color hot-pressing label special for resin grinding wheels. Background technique [0002] The traditional method of marking information such as grinding wheel specifications, models, particle sizes, trademarks, etc. is to stamp the finished grinding wheel. Due to the manual method, the clarity and efficacy are not satisfactory. Later, engraving was used to manually spray the handwriting on the finished grinding wheel. Because the working environment during the spraying was too bad, it directly affected the health of the workers, and it needed to be dried or dried individually. The effect was low and the environment was polluted. The effect was rough, The single color affects the aesthetics of the grinding wheel. After repeated research by the applicant, he found a "hot press label" that can be pressed together with a grinding wheel for high temperature vulcanization and drying. The label uses 28 grams of...

Problems solved by technology

[0002] The traditional method of marking the grinding wheel specification, model, grain size, trademark and other information is to stamp the finished grinding wheel. Due to the manual method, the clarity and efficacy are not satisfactory

Finally, the hand-sprayed handwriting on the finished grinding wheel is used to engrave and stencil. Because the working environment during spraying is too harsh, it directly affects the health of the workers, and it needs to be dried or dried individually. The effect is low and it pollutes the environment. The effect is rough. The color is single, which affects the aesthetics of the grinding wheel

After repeated research by the applicant, a "hot press label" that can be hot pressed together with a grinding wheel for high temperature vulcanization and drying was found. Afterwards, various technical data and trademark patterns are overprinted. Although it has certain aesthetics, it is not suitable for automatic printing due to the thin thickness of pure cotton paper. Manual printing can only be used. The work efficiency is too low to meet the requirements of modern production. need

At present, the industry has also produced some heat-pressed labels for grinding wheels according to their actual needs, but the color change range cannot be controlled when this kind of label is used, and the color change range is very large after sintering
