Description

A kind of chemically toughened glass and preparation method
Technical field
The present invention relates to tempered glass more particularly to a kind of chemically toughened glass and preparation methods.
Background technique
Tempered glass is a kind of prestressed glass, is that annealed glass is processed into required size and shape, by high temperature plus Heat handles to obtain to softening point temperature using quenching.Tempered glass mechanical strength with higher, impact strength, bending resistance Intensity, and there is good safety and thermal stability, it is most common safety glass form.Chemically toughened glass is made For one kind of tempered glass, it is that plate glass by heating is close to glass softening point, is sent into curved be compression molded into immediately after Type carries out hurried, cooling gained after molding.Due to the property of chemically toughened glass, purposes is quite extensive, can be used for The safety decorative glass of skyscraper, all kinds of buildings, various types of vehicles, aircraft, glass pane of ship etc..
Mainly there are physical toughened and two kinds of chemical tempering for the production technology of tempered glass at present.Physical toughened glass master If ordinary plate glass is heated in heating furnace close to the softening temperature of glass, internal answer is eliminated by self-deformation Power is finally made by quenching processing.Chemically toughened glass changes the chemical group of glass surface generally by ion-exchange At improving strength of glass.With physical toughened glass phase ratio, the production cycle of chemically toughened glass is long, and low efficiency is to be produced into This height.Therefore, physical toughened method is mostly used to prepare tempered glass greatly at present.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the present invention provides a kind of chemically toughened glass and preparation side Method.
A kind of chemically toughened glass, chemically toughened glass include following components by weight percent: 200-250 parts of quartz sand, kaolin 80-120 parts, 70-100 parts of dolomite, 12-25 parts of barium monoxide, 33-45 parts of feldspar, 1-5 parts of potassium chloride, 15-26 parts of clarifying agent, 6-18 parts of molybdenum trioxide, 4-19 parts of magnesia, 7-21 parts of disodium ethylene diamine tetraacetate, 6-20 parts of ethyl orthosilicate, potassium permanganate 5-29 parts, 5-29 parts of zirconium carbonate ammonium, 3-29 parts of triethanolamine.
