Problems solved by technology

[0002] With the wide application of glass products in the fields of industry, medicine and buildings, the existing demand for glass is not limited to blocking and light transmission, but more is the demand for good mechanical strength of glass, such as Good fracture resistance and high hardness. In our actual use process, except for a small amount of special glass, conventional glass has poor impact resistance and fracture resistance, so it does not have good stability and is prone to occur during use. Some damage problems, so improving the fracture resistance of glass can effectively improve the performance of glass, expand the scope of use of glass, and have a good market space

Abstract

The invention discloses a fracture-resistant composite glass and a preparation process thereof. The glass is composed of the following raw material components: SiO2, ZrO2, CeO2, P2O5, BaO, Sb2O3, Li2O, MoO3 and Na2O; the preparation steps of the glass are as follows : 1), select raw materials, mix at room temperature, 2), pulverize through a pulverizer, pass through a 200-300 mesh sieve after pulverization, and ventilate and dry after sieving, 3), add the dried raw materials into a corundum crucible for heating, After the temperature reaches the highest, keep the temperature constant for 2-3h while stirring, 4), after clarification, pour the molten glass into the mold and carry out annealing treatment to obtain a fracture-resistant composite glass material; the composite glass material prepared by the present invention overcomes the The problem of low fracture toughness and low elastic modulus of conventional glass materials has effectively improved the fracture resistance of composite glass, has good impact resistance, and has no damage to glass materials.

Description

technical field [0001] The invention relates to a glass, in particular to a fracture-resistant composite glass and a preparation process thereof. Background technique [0002] With the wide application of glass products in the fields of industry, medicine and buildings, the existing demand for glass is not limited to blocking and light transmission, but more is the demand for good mechanical strength of glass, such as Good fracture resistance and high hardness. In our actual use process, except for a small amount of special glass, conventional glass has poor impact resistance and fracture resistance, so it does not have good stability and is prone to occur during use. Some breakage problems, so improving the fracture resistance of glass can effectively improve the performance of glass, expand the scope of use of glass, and have a good market space. Contents of the invention [0003] The main purpose of the present invention is to propose anti-fracture composite glass and ...
