Problems solved by technology

[0003] The softening point of conventional ion-exchangeable glass used as cover glass in consumer electronic devices is usually greater than or equal to 840 ° C. Glasses with softening points in this range are easily suitable for molding, but this glass is not suitable for elevated temperatures. Formed into 3D shapes
Specifically, the higher softening point of glass causes the material of the glass and ...

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0025] The 3D forming colorable ion-exchange aluminosilicate glass of the present invention contains the following components by mass percentage, SiO 2 55%~75%, Al 2 o 3 7% to 23%, B 2 o 3 0~5%,Na 2 O 3%~25%, K 2 O 0~6%, P 2 o 5 0~5%, ZnO 0~6%, MgO 0~3%, CaO 0.1%~3%, SnO 2 0~4%.

[0026] The function and specific content of each component in the above-mentioned 3D formable colorable ion-exchanged aluminosilicate glass are discussed below, and the unit of content is mass percent.

[0027] SiO 2 : 55% to 75%.

[0028] SiO 2 It is an essential component for forming a glass skeleton. When SiO in glass 2 At lower concentrations, the resulting glass has lower chemical durability, however, if the glass contains SiO 2 The concentration of SiO is too high, which can reduce the form...

Abstract

The invention discloses 3D-shaped colorable ion exchange glass and a preparation method thereof. The glass comprises 55-75% of SiO2, 7-23% of Al2O3, 0-5% of B2O3, 3-25% of Na2O, 0-6% of K2O, 0-5% of P2O5, 0-6% of ZnO, 0-3% of MgO, 0.1-3% of CaO and 0-4% of SnO2. The preparation method comprises the following steps: step 1, subjecting the above raw materials to melting and molding to form flat glass; step 2, performing high-temperature annealing treatment; step 3, carrying out ion exchange in the molten salt of a coloring agent at 380-450 DEG C for 1-6 h, wherein the molten salt of the coloring agent molten salt is composed of 30%-50% of copper nitrate, 20%-35% of potassium nitrate and 20%-35% of sodium nitrate; and step 4, carrying out cooling to 80 DEG C from 400 DEG C within 1 h to obtain the glass. The glass has a low softening point and can meet the artistic demand on product shapes through reprocessing.

Description

technical field [0001] The invention relates to the technical field of 3D glass manufacturing, in particular to a 3D shaped and colorable ion exchange glass and a preparation method thereof. Background technique [0002] With the development of modern display technology, a large number of flat panel display products such as liquid crystal display, cash machine protection screen, touch screen information inquiry machine and media advertising player have emerged and entered our daily life. With the improvement of people's material and cultural living standards, Shape, color and suitability of these display products are increasingly sought after. [0003] The softening point of conventional ion-exchangeable glass used as cover glass in consumer electronic devices is usually greater than or equal to 840 ° C. Glasses with softening points in this range are easily suitable for molding, but this glass is not suitable for elevated temperatures. Molded into 3D shapes. Specifically,...
