Detailed Description
The technical solutions of the embodiments of the present application are described below with reference to the drawings.
Fig. 1 is a schematic cross-sectional structural view of a strengthened glass article provided in an embodiment of the present disclosure. As shown in fig. 1, the strengthened glass article 100 includes a first surface 10a and a second surface 10b disposed opposite to each other, a first compressive stress layer 101 extending from the first surface 10a to a predetermined depth in the strengthened glass article 100, and a second compressive stress layer 102 extending from the second surface 10b to a predetermined depth in the strengthened glass article 100, wherein the first surface 10a is a frosted surface, the second surface 10b is a non-frosted surface, and a side of the second compressive stress layer 102 away from the second surface 10b is wavy and has a plurality of peaks and a plurality of valleys alternately (i.e., a side of the second compressive stress layer 102 away from the second surface 10b has a plurality of peaks spaced apart from each other, and a valley exists between two adjacent peaks). Wherein the wave crests correspond to the maximum depth of the second compressive stress layer 102 and the wave troughs correspond to the minimum depth of the second compressive stress layer 102.
One side surface of the strengthened glass product is a frosted surface, the other side surface of the strengthened glass product is a non-frosted surface, the compression stress layers on the two side surfaces are different and are in asymmetric distribution, the depth of the compression stress layer 102 on the non-frosted surface side is different, and the compression stress layer has a periodic trend of alternately high depth and shallow depth in the direction parallel to the non-frosted surface (namely, the x direction in fig. 1), so that if a crack exists in a tension pressure area clamped between the two asymmetric compression stress layers, the expansion of the crack can be fully inhibited, and particularly, the special structure of the compression stress layer on the non-frosted surface side greatly increases the contact area of the crack which can be blocked, thereby greatly reducing the influence of the crack on the strength of the glass product, and improving the mechanical properties such as the fracture threshold, bending strength, impact resistance and the like.
In the present application, the distance between the peak and the second surface 10b is denoted as H1The distance of the trough from the second surface 10b is denoted as H2It is understood that H1Greater than H2. Wherein H2May be H1Can be, for example, 25%, 30%, 35%, 40%, 50%, 55%, 60%, 70%, 75%, etc., and in some embodiments, H is present in an amount of about 20-80%, or more specifically about 25%, 30%, 35%, 40%, 50%, 55%, 60%, 70%, or 75%, etc2May be H130-60 percent of the total weight of the powder. This may cause the side of the second layer 102 remote from the second surface 10b to be substantially wavy, which may be more clearly distinguished from the first layer 101. In some embodiments of the present application, the distance H of the peak from the second surface 10b1Greater than or equal to 100 μm. E.g. H1Is 100 μm to 200 μm. The distance H of the trough from the second surface 10b2Greater than or equal to 50 μm. E.g. H2Is 50-160 μm.
Further, referring to fig. 2, the second compressive stress layer 102 includes a first compressive stress region 1021 extending from the second surface 10b into the strengthened glass article, and a second compressive stress region 1022 extending from the second surface 10b into the strengthened glass article, wherein the first compressive stress region 1021 includes one of the peaks, and the second compressive stress region 1022 includes one of the valleys, and the first compressive stress region 1021 and the second compressive stress region 1022 are distributed at intervals and are adjacent to each other along a direction (x direction in the drawing) parallel to the second surface 10 b. Is defined between the trough and the crestAny plane parallel to the second surface 10b is a boundary plane of the first compressive stress region 1021 and the second compressive stress region 1022 (its distance from the second surface is denoted as H)x) At any same depth between the horizontal plane in which the trough lies and the bounding surface (i.e. at a depth between H2And HxAt any same depth therebetween), the compressive stress of the first compressive stress region 1021 is greater than the compressive stress of the second compressive stress region 1022.
As shown in fig. 2, a projection of an intersection point of the defining surface and the first compressive stress region 1021 on the second surface is A, B, and a projection of an intersection point of the defining surface and the second compressive stress region 1022 on the second surface is B, C, then a horizontal distance between A, B is a width of the first compressive stress region 1021, and a horizontal distance between B, C is a width of the second compressive stress region 1022.
Since the first compressive stress region 1021 includes a peak and the second compressive stress region 1022 includes a valley, it will be appreciated that the maximum depth of the first compressive stress region (i.e., the distance of the peak from the second surface) is greater than the maximum depth of the second compressive stress region. The above-mentioned defining surfaces may be at equal distances from the peak and the trough, or may be close to the peak or close to the trough, and preferably, the defining surfaces are close to the trough (i.e. the distance from the trough to the defining surfaces is less than the distance from the peak). It will be appreciated that when the depth of the valleys of the second layer 102 is different, the defining surface is selected primarily for adjacent peaks and valleys.
In the present embodiment, the distance from the second surface 10b is 0 to a third depth (denoted as H)3) At any same depth within the range of (a), the compressive stress of the first compressive stress region 1021 is substantially equal to the compressive stress of the second compressive stress region 1022; wherein the third depth H3Less than the distance H of the trough from the second surface 10b2And the third depth H3Not exceeding 50 μm. By "substantially equal" is meant that the compressive stress F of the first compressive stress section 1021 is1Compressive stress F with the second compressive stress region 10222Does not exceed 1%, i.e., the degree of deviation k ═ F1-F2|/F1K is less than or equal to 1 percent. Alternatively, k is 0.5%, in some cases k is 0.1%, and even k is 0. In other words, the second compressive stress layer 102 includes a second extension from the second surface 10b to a depth H3A uniform compressive stress layer (as shown in fig. 3). The uniform compressive stress layer is a stress layer with substantially equal compressive stress in the same depth, and is mainly formed by secondary chemical strengthening.
In addition, the depth of the second compressive stress layer is greater than the H3The compressive stress in the second compressive stress layer decreases with increasing depth. Specifically, the first compressive stress region 1021 is deeper than H3To H1In the range of (1), the compressive stress thereof decreases with increasing depth; the second compressive stress region 1022 is deeper than H3To HxIn the range of (1), the compressive stress thereof decreases with increasing depth. At this time, in FIG. 2, the third depth H is set between3At any depth from the above-mentioned bounding surface (i.e. depth between H)3And HxAt any same depth therebetween), the compressive stress of the first compressive stress region 1021 is greater than the compressive stress of the second compressive stress region 1022.
Optionally, the compressive stress of the second compressive stress layer 102 at a depth of 50 μm from the second surface 10b is greater than or equal to 10 MPa.
In the present embodiment, the surface compressive stress of the second compressive stress layer 102 at the second surface 10b is equal to the surface compressive stress of the first compressive stress layer 101 at the first surface 10 a. Wherein the surface compressive stress of the second compressive stress layer 102 at the second surface 10b is greater than or equal to 550MPa, such as at 550-1000 MPa.
In the present application, the depth of the first compressive stress layer 101 is substantially constant along the x-direction in fig. 1. In the present embodiment, the depth of the first compressive stress layer 101 may be equal to the maximum depth of the second compressive stress layer 102 (i.e., the distance H of the peak from the second surface 10 b)1) As shown in fig. 3. Similarly, the first compressive stress layer 101 also has a depth H extending from the first surface 10a to the inside3' a uniform compressive stress layer. H is made of3' with the above H3And are equal. Wherein the surface of the first compressive stress layer 101The surface compressive stress is greater than or equal to 550MPa, for example, in the range of 550MPa to 1000 MPa.
In the embodiment of the present application, the thickness of the tempered glass product may be 0.3mm to 5 mm. Specifically, the thickness may be 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 2mm, 3mm, 4mm, or the like. In some embodiments, the thickness may be 0.4mm to 2 mm. At the moment, the electronic equipment shell adopting the tempered glass product is lighter and thinner, and the mechanical property of the electronic equipment shell is better.
In an embodiment of the present application, the strengthened glass product has a flexural strength of 800MPa or more. The higher bending strength reflects the better toughness and less tendency to crack of the strengthened glass product. In some embodiments, the flexural strength is 800-1200Mpa, and further may be 900-1200 Mpa.
In an embodiment of the present application, the strengthened glass article has an impact energy of 0.5J or more. The larger impact strength reflects the strong impact resistance of the tempered glass and is not easy to break. In some embodiments, the impact energy is 0.6J or greater, such as 0.6J to 3J.
The strengthened glass article can be produced by the following method. Specifically, the following steps may be included:
(1) arranging protective layers on other surfaces of the glass body except the surface to be frosted (such as a first surface), then placing the glass body in a frosting solution to convert the first surface into a frosted surface (namely, obtaining frosted glass), and removing the protective layers;
(2) locally shielding a second surface opposite to the frosting surface, and then chemically strengthening the glass body after local shielding for the first time;
(3) removing the shielding pattern, and performing a second chemical strengthening to obtain the strengthened glass product.
In the step (1), the protective layer is typically an acid-resistant polymer film (such as polyethylene terephthalate (PET), or an ink layer, etc. the protective layer can be removed by physical removal such as sanding, polishing, etc., or chemical removal such as alkali etching, etc.
In the step (2), the shielding pattern may be formed on the surface of the glass body through a screen printing process, a coating process (such as spraying), a plating process, or an exposure and development process. The masking pattern is typically a high temperature resistant material. The shielding pattern may include a plurality of shielding layers distributed at intervals, and the shape of the shielding layers (specifically, the projection shape thereof on the glass substrate) may include a regular shape such as a circle, an ellipse, a triangle, a rectangle, a polygon, or an irregular shape. The existence of the shielding pattern can block ion exchange between ions in the strengthened molten salt and the glass part shielded by the shielding pattern, and further the strengthened glass with the asymmetric pressure stress layer can be formed. Optionally, the total coverage of the shielding pattern on the second surface of the glass body is 10% -50%. This reduces distortion caused by asymmetrical stress distribution on the surfaces on both sides of the glass. In the step (3), the removal of the shielding pattern can be realized by at least one of a mechanical polishing technology and a soaking method in the liquid medicine.
The molten salt used for the first chemical strengthening can be only a sodium salt or a mixture of the sodium salt and a potassium salt. The molten salt used for the second chemical strengthening can be only potassium salt or a mixture of sodium salt and potassium salt. The molten salt used for the two-step chemical strengthening can be determined according to the specific material of the glass body. Typically, the glass body is lithium aluminosilicate glass.

For the case that the electronic device is a portable electronic device such as a mobile phone, a tablet computer, a wearable product, etc., the electronic device housing may be a display screen cover plate specifically assembled on the front side of the electronic device, and the display screen cover plate is covered on the display module; a rear cover assembled to the rear side of the electronic apparatus is also possible. In some embodiments, when the electronic device is an electronic device with a camera function (e.g., a mobile phone or a digital camera), the electronic device housing may also be a camera protection cover.
