Abstract

The invention belongs to the field of chemical engineering synthesis, and concretely discloses an ultrathin toughened glass. The glass mainly comprises, by weight, 80-85% of SiO2, 4-6% of Al2O3, 15-22% of CaO, 3-5% of MgO and 19-20% of Na2O, and also comprises 0.003-0.010% of Fe2O3, 15% or more of K2O + Na2O, 0.5-0.7% of Sb2O3 and 1-2% of ZrO, wherein the content of Na2O is greater than the content of K2O. Above components undergo transverse conclusion connection under the guiding of B2O3 and ZnO to realize float process flow molding. The whole ultrathin glass has high drawing ability and enough toughness, can resist large impact and shock, and is convenient to move and use.

Description

technical field [0001] The invention relates to the field of chemical synthesis, in particular to an ultra-thin tough glass and a preparation method thereof. Background technique [0002] The existing ultra-thin glass is mostly made by the float method. When the float method is made, the glass solution is used to naturally form a thin layer on the tin bed by gravity. This thin layer is formed by the ultra-thin glass. Because the glass The melt is naturally formed under the state of gravity. The distance between the tissues is large and the combination is not tight. It is very easy to generate bubbles and reduce the toughness of the glass and increase the brittleness. This makes the ultra-thin glass easy to break, resulting in glass cracking and potential safety hazards. . Contents of the invention [0003] The purpose of the present invention is to provide an ultra-thin tough glass and a preparation method thereof, so as to improve the problem of low toughness in the prod...
