Abstract
The invention relates to a preparation process of a toughened glass. The formula of a catalyst adopted by the process comprises the following materials in percentage by weight: 12-14 % of barium oxide, 50-60 % of potassium silicate, 12-14 % of silicon dioxide and 14-20 % of potassium hypermanganate. Through the adding of the catalyst, the toughening time can be reduced, a surface pressure layer of the toughened glass is thickened and the toughening strength is enhanced.
Description
[technical field]
The invention belongs to the glass preparation field, be specifically related to the preparation technology of toughened glass.
[technical background]
The mode of glass tempering has physical toughened and chemical tempering at present, and chemically toughened glass intensity and physical toughened glass approach, Heat stability is good, treatment temp is low, and product is not yielding, and its product is not subjected to the restriction of thickness and geometrical shape, use equipment is simple, and product is easily realized.But with physical toughened glassy phase ratio, the chemically toughened glass production cycle long (reach tens of hours swap time), efficient is low and production cost is high.
The principle of chemical enhancement method is: the surface composition that changes glass according to the mechanism of ion diffusion, at a certain temperature glass is immersed in the high-temperature molten salt, mutual exchange occurs because of diffusion in the alkalimetal ion in the glass and the alkalimetal ion in the fused salt, produce " jammed " phenomenon, make glass surface produce stress under compression, thereby improve the intensity of glass.But the bearing stress layer that ion exchange method produces is thinner, and the effects on surface microdefect is very responsive, and very little surface tear just is enough to make strength of glass to reduce.Ba
2+Diameter less than K
+, more be conducive to entering of ion, the surface pressure layer is thickened.
Purpose of the present invention is exactly in order to overcome the shortcomings such as long and bearing stress layer of tempering time that above-mentioned prior art exists is thinner, a kind of new catalyst and preparation technology to be provided.
[summary of the invention]
