Problems solved by technology

[0004] However, at least the following problems still exist in the currently used tempered glass: 1. The current tempering treatment only changes the composition of the glass surface (chemical tempering) or does not change the composition of the glass (quenching tempering), and is limited by the glass substrate. The compressive stress of tempered glass can meet the actual needs, but the impact resistance is poor, that is, the toughness is poor; 2. When the surface compressive stress is large, the self-explosion rate is high and the defective rate is high

Abstract

The invention discloses a high-toughness toughened glass and a preparation method thereof, comprising the following raw materials in parts by weight: 600-700 parts of quartz sand, 125-165 parts of fluorite, 90-115 parts of potassium feldspar, iron-containing compound 75-90 parts of fiber, 50-65 parts of silicon carbide fiber, 95-110 parts of alumina fiber, 35-45 parts of zinc oxide, 40-55 parts of zirconium boride, and 40-60 parts of sodium bismuth titanate. The present invention selects the constituent raw materials of high-toughness tempered glass and optimizes the ratio of the constituent raw materials of high-toughness tempered glass. Glass has high impact strength and bending strength, good toughness, good mechanical properties, and is not easy to damage; the surface compressive stress is large, and the self-explosion rate is low.

Description

technical field [0001] The invention relates to the field of tempered glass materials, in particular to a high-toughness tempered glass and a preparation method thereof. Background technique [0002] Tempered glass (Tempered glass / Reinforced glass) belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Wind pressure, cold and heat, impact, etc. [0003] Tempered glass is widely used in automobiles, construction, industry and other fields due to its high impact strength, excellent thermal shock resistance, good safety and other advantages. Tempered glass is a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. strength. [0004] However, at least the following problems still exist in the currently us...
