Abstract
The invention discloses a safety strengthening agent in a touch-control glass tempering process. The safety strengthening agent comprises the following raw materials in parts by weight: 1-5 parts of Cs2O, 10-30 parts of alkylether carboxylate (AEC), 1-5 parts of Rb2O, 10-50 parts of amino acid potassium salt, 1-10 parts of B2O3, 2-10 parts of Al2O3 and 1-10 parts of MgO2.
