Abstract

The invention discloses impact-resistant toughened glass prepared from a semi-matt lead-free glass powder and a preparation method of the toughened glass. The preparation method includes the steps: weighing NiO, MnO, MgO and Sb2O3 according to the ratio, mixing the NiO, the MnO, the MgO, Sb2O3 and a certain H3BO4 for standby application, melting mixture at the high temperature of the 1000-1250 DEGC, rapidly pouring the mixture into purified water after discharging, weighing Cr2O3, Fe2O3, Bi2O3, NaF and TiO2 according to ratio, and mixing the Cr2O3, the Fe2O3, the Bi2O3, the NaF and the TiO2 for standby application; melting mixture at the high temperature of the 1000-1250 DEG C, rapidly pouring the mixture into purified water after discharging to form cold hardening particles, and drying the particles; mixing the particles and the mixture for standby application; weighing materials without being matched according to the ratio, performing secondary mixing on the materials without beingmatched and the mixture, crushing and pretreating mixture, melting screened mixture at the high temperature, and rapidly pouring the mixture into purified water to perform cold quenching; collecting and drying the mixture, and finely grinding the mixture to obtain glass powder. The impact-resistant toughened glass solves the problems that a glaze layer reflects light and a surface layer is matte in the secondary melting process of a glass body.

Description

technical field [0001] The invention relates to the technical field of glass powder, in particular to a semi-matt lead-free glass body powder for automobile rear glass and a preparation method thereof. Background technique [0002] Existing rear windshield glass for automobiles, the glass powder ink layer with better application effect generally contains lead, and lead-free glass powder products are also sold on the market, but the glaze layer is formed during the secondary melting process, and the surface layer is not inferior. Light, low intensity. The tempering effect of the ink prepared by mixing different components of the glass body is prone to substandard effects, the glass is easy to change color under the acidic conditions after tempering, and the formation of mixed crystals during the formation of the glass body makes the masking effect worse after mixing glass powder and pigments. . Contents of the invention [0003] In order to overcome the above-mentioned de...
