Abstract

The invention discloses a preparation technology of toughened glass. The preparation technology comprises the following steps: (1) polishing, cleaning and drying glass; (2) pre-heating the dried glass for 4 to 5 hours at a temperature of 300 to 310 DEG C; (3) adding following components in parts by weight into a toughening treatment tank: 3 to 5 parts of barium oxide, 10 to 15 parts of potassium silicate, 11 to 12 parts of silicon dioxide, 15 to 20 parts of potassium permanganate, and 300 parts of sylvite; (4) putting the pre-heated glass into the toughening treatment tank, allowing the glass to stand still for 13 to 14 hours, controlling the temperature in a range of 480 to 490 DEG C; (5) putting the toughened glass into a heat dissipation furnace with a temperature of 300 to 310 DEG C, taking out the glass when the temperature decreases to 40 DEG C, then putting the glass into hot water with a temperature of 80 DEG C, and allowing the glass to stand still for 2 to 3 hours so as to obtain the finished product. The preparation technology of toughened glass can reduce the toughening time, and thickens the surface compressive stress layer.

Description

The preparation technology of toughened glass

Technical field

The present invention relates to the preparation technology of toughened glass.

Background technology

The preparation technology of current toughened glass, the tempering time is long, and makes bearing stress layer thinner.

Summary of the invention
