Abstract: Ink-jet printing technology for soda-lime-silicon flat glass surface is an important development tendency in the field of deep processing of glass.The surface decoration coating is prepared by ZnO-B2O3-SiO2glass and inorganic pigments.However, due to low hardness of the coating, wear resistance and scratch resistance of coating cannot meet the needs of the field of architectural decoration.Therefore, ZrO2was introduced for the preparation of high hardness coating.The effects of ZrO2on the preparation process,color and hardness of coating were studied.The results show that the microhardness of the coating treated at 580 ℃/30 min is increased to 632.7 HV with 3wt% ZrO2addition.ZrO2did not interact with low melting glass and inorganic pigment during sintering process.The main crystal phase Co2TiO4of inorganic green pigments keeps unchanged, so that the coating color remaines stable.The coating is capable of good decorative function.
