High-toughness tempered glass and preparation method thereof

The invention discloses high-toughness toughened glass and a preparation method thereof, and belongs to the technical field of toughened glass materials, and the high-toughness toughened glass comprises the following raw materials in parts by weight: 500-800 parts of quartz sand, 60-80 parts of limestone, 100-150 parts of sodium carbonate, 40-70 parts of soda-lime glass, 5-15 parts of borate, 10-20 parts of phosphate, 7-15 parts of a toughening agent, 15-25 parts of bauxite, 5-18 parts of borax and 30-55 parts of a glass modified toughening agent. The preparation method of the glass modified toughening agent comprises the following steps: mixing the toughening agent, the organic silicon resin and the solvent, uniformly stirring, adding the polymer elastomer and the organic auxiliary agent, and continuously stirring. The toughening agent, the organic silicon resin, the polymer elastomer, the organic auxiliary agent and the filler are mixed, crosslinked and dried to form the glass modified toughening agent adde
