Problems solved by technology

[0002] Alkali metals are needed in the preparation process of the existing glass. Due to the addition of alkali metals, the prepared glass is prone to diffusion and exchange of alkali metals in some later processing processes, thereby generating internal stress and affecting the mechanical properties of the glass itself. , so that the mechanical strength and light transmittance of the glass are affected to a certain extent

Abstract

The invention discloses an explosion-proof glass material and a preparation method thereof. The above-mentioned explosion-proof glass material is made of the following components by weight: 75-80 parts of silicon dioxide, 8-11 parts of boron oxide, 2-3 parts of silicon phosphoric acid 1-2 parts of methyltriacetoxysilane, 1-1.5 parts of magnesium aluminosilicate, 1-1.5 parts of sodium metabismuth, 0.5-0.9 parts of cerium nitrate hexahydrate, 0.5-0.8 parts of rutile, tripolyphosphoric acid 0.05-0.5 part of sodium, 0.02-0.4 part of lead oxide and 0.02-0.05 part of polydimethylsiloxane diquaternary ammonium salt. The invention also provides a preparation method of the explosion-proof glass material.

Description

technical field [0001] The invention belongs to the field of glass materials, in particular to an explosion-proof glass material and a preparation method thereof. Background technique [0002] Alkali metals are needed in the preparation process of the existing glass. Due to the addition of alkali metals, the prepared glass is prone to diffusion and exchange of alkali metals in some later processing processes, thereby generating internal stress and affecting the mechanical properties of the glass itself. , so that the mechanical strength and light transmittance of the glass are affected to a certain extent. [0003] Explosion-proof glass has good mechanical strength, which can greatly reduce the damage to nearby personnel and valuables when the glass encounters violent impact. How to manufacture glass with good mechanical strength and light transmittance, and good explosion-proof and crack resistance has also become people are increasingly concerned about. Contents of the ...
