Abstract

The invention relates to a fracture-resistant composite glass material and a preparation method thereof. The fracture-resistant composite glass material is composed of the following components according to the weight ratio: 5-10 parts of P2O5, 3-6 parts of BaO, and 4-6 parts of Sb2O3 , Na2O is 8-12 parts, MgO is 10-13 parts, and SiO2 is 27-33 parts. The method for preparing the fracture-resistant composite glass material includes crushing, sieving, melting, ventilating and stirring, annealing and the like. The prepared composite glass material has good fracture resistance and high fracture toughness, which can meet the needs of high-toughness glass.

Description

technical field [0001] The invention relates to a composite glass material and a preparation method thereof, in particular to a glass material with good fracture resistance and a preparation method thereof. Background technique [0002] There are many kinds of glass, which can be divided into vertical lead-up method, flat pull method, float method and so on according to the different manufacturing processes. Conventional glass materials can be divided into frosted glass, tempered glass, coated glass, light-transmitting glass, etc. according to different properties. If a certain metal compound is added during the glass melting process, the glass can also have a specific color to meet the different needs of customers. [0003] In our actual use process, except for a small amount of special glass, conventional glass is usually prone to breakage when it is hit. Fracture-resistant glass is less common. Improving the fracture resistance of glass can effectively improve the perf...
