Abstract
The present invention provides a kind of preparation methods of high strength slim glass, and raw material includes following component according to weight percent: silica 60-65 parts by weight, aluminium oxide 10-17 parts by weight, sodium oxide molybdena 11-15 parts by weight, magnesia 3-13 parts by weight, zirconium oxide 0-3 parts by weight；The preparation method of the high strength slim glass, includes the following steps: 1) melting sources: above-mentioned raw materials being added directly into the melting furnaces of 1300 degrees centigrades, forms glass metal；2) glass metal is clarified: temperature being increased to 1400-1500 degrees Celsius, glass metal is formed, visible bubble in bubble and dissolved gas therein is discharged；3) glass metal is homogenized: glass being chronically under high temperature, the striped in glass metal is eliminated, forms the glass metal of homogenizing.The present invention improves the tensile strength of glass by reasonably adjusting glass formula and preparation process, and the strain point of glass, annealing point, softening point, the coefficient of expansion, density mechanical strength, photoelectric information performance is made to meet the requirement of ultra-thin cover-plate glass.
Description
Technical field
The present invention relates to a kind of preparation methods of high strength slim glass, belong to optical element field.
Background technique
With the fast development of touch screen display industry, the thickness requirement of touched panel glass surface protection glass is got in market
Come thinner, the ultrathin of glass has become one of important trend of glass.Touched panel glass surface protection thickness of glass
It is required that being less than 1mm, super-thin electronic glass product has been widely used in smart phone, tablet computer, AG glass, protection glass
In equal display terminals.
However ultrathin also brings apparent drawback, that is exactly the reduction of mechanical strength.It reducing weight, reducing
While volume, impurity, defect and any negative factor for reducing strength of glass can be all amplified.Such as: it is one slight
Crackle or defect are an inappreciable flaw on surface for the glass of general thickness, but relative to ultra-thin glass
For, an equal amount of crackle may but go deep into inside glass, and the destruction that can not ignore is caused to its intensity.This directly makes
Common plate glass is lagged significantly behind on the mechanical performance indexs such as flexural strength, surface hardness at ultra-thin glass, this gives
The practical application of ultra-thin glass brings huge obstruction.
Summary of the invention
The purpose of the present invention is to overcome the deficiencies of the prior art, provides a kind of preparation side of high strength slim glass
Method.
The preparation method of high strength slim glass of the invention, raw material include following component according to weight percent: oxidation
Silicon 60-65 parts by weight, aluminium oxide 10-17 parts by weight, sodium oxide molybdena 11-15 parts by weight, magnesia 3-13 parts by weight, zirconium oxide 0-3
Parts by weight；
The preparation method of the high strength slim glass, includes the following steps:
1) melting sources: above-mentioned raw materials being added directly into the melting furnaces of 1300 degrees centigrades, forms glass metal；
2) glass metal is clarified: temperature is increased to 1400-1500 degrees Celsius, forms glass metal, be discharged visible bubble in bubble therein and
Dissolved gas；
3) glass metal is homogenized: glass being chronically under high temperature, the striped in glass metal is eliminated, forms the glass metal of homogenizing；
4) glass metal is cooling: by the glass metal uniform decrease in temperature after clarification and homogenization, glass molding；
5) tempering processing is carried out to high strength slim glass made of step 4) using ion-exchange, specific processing step is such as
Under: after glass is carried out ultrasonic cleaning, scrub, through 200 ~ 300 degrees Celsius of the pre-heat treatments, it is then immersed in 450 degrees Celsius of meltings
Ion-exchange treatment is carried out in KNO3.
The present invention improves the tensile strength of glass, makes answering for glass by reasonably adjusting glass formula and preparation process
Height, annealing point, softening point, the coefficient of expansion, density mechanical strength, photoelectric information performance meet the requirement of ultra-thin cover-plate glass.
