preparation example Construction

[0020] The present invention also provides a preparation method of a tempering liquid composition for improving the flexural strength of glass, wherein the preparation method may include the following steps: (1) adding 86-95 parts by weight of potassium nitrate and 2-6 parts by weight of Potassium chromate is mixed and warmed up to complete melting, obtains the first mixture; (2) the potassium sulfate of 0-1 weight part and the potassium sulfate of 3-7 weight part are mixed with the first mixture that step (1) obtains, and Keeping the constant temperature in the molten state for not less than 2 hours, specifically, the time for keeping the constant temperature can be 2-4 hours or 2-6 hours, etc., to obtain a molten tempering liquid composition.

[0021] In the above preparation method of the tempering liquid composition for improving the flexural strength of glass, the sum of parts by weight of potassium nitrate, potassium dichromate, potassium silicate and potassium sulfate ma...

Embodiment 1

[0038] (1) mix the potassium nitrate of 86 parts by weight and the potassium dichromate of 6 parts by weight and be warming up to all melting, obtain the first mixture; (2) mix the potassium sulfate of 1 weight part and the potassium sulfate of 7 parts by weight with The first mixture obtained in step (1) was mixed and kept in a molten state at a constant temperature of 420° C. for 2 hours to obtain a molten tempering fluid composition GHY-1.

[0039] Put the original glass sheet preheated at 350°C into the molten tempering liquid composition GHY-1, immerse the glass in the molten tempering liquid composition GHY-1, and keep the temperature at a tempering temperature of 420°C for 3 hours After cooling, washing and drying, the glass with improved bending strength of this embodiment is obtained.

Embodiment 2

[0041] (1) mix the potassium nitrate of 94 parts by weight and the potassium dichromate of 2 parts by weight and be warmed up to melt completely, obtain the first mixture; (2) mix the potassium silicate of 1 part by weight and the potassium sulfate of 3 parts by weight After uniformity, mix with the first mixture obtained in step (1), and keep it in a molten state at a constant temperature of 420° C. for 2 hours to obtain molten tempering fluid composition GHY-2.

[0042] Put the original glass sheet preheated at 350°C into the molten tempering liquid composition GHY-2, immerse the glass in the molten tempering liquid composition GHY-2, and keep the temperature at a tempering temperature of 420°C for 3 hours After cooling, washing and drying, the glass with improved bending strength of this embodiment is obtained.

Abstract

The invention discloses a toughened solution composition and a preparation method thereof and a method for improving bending strength of glass and chemically-toughened glass. The toughened solution composition comprises the following components in percentage by weight: 86-95% of potassium nitrate, 3-7% of potassium sulphate, 2-6% of potassium dichromate, and 0-1% of potassium silicate. With the adoption of the toughened solution composition and a treating method, the bending strength of glass can be rapidly and greatly improved and is increased by 20% or more, and thus the mechanical performance of the glass can be effectively improved.

Description

technical field [0001] The invention relates to glass bending resistance technology, in particular to a tempering liquid composition and a preparation method thereof, a method for improving the bending strength of glass, and chemically tempered glass. Background technique [0002] Ultra-thin glass is more and more widely used in electronic products such as mobile phones and flat panel displays, but the reduction in mechanical strength of glass brought about by thinning and thinning has greatly hindered its application in actual production. In order to improve the mechanical properties of ultra-thin glass, the glass chemical tempering method is usually used, that is, by immersing the glass in a molten salt of alkali ions, and replacing the sodium ions with a smaller radius in the glass with potassium ions with a larger radius in the molten salt. , to "squeeze" the network structure of the glass surface to form a pre-compressed stress layer on the glass surface, so that it has...
