Abstract

A laminated glass includes at least two glass members and at least one adhesive film disposed in a stacked manner, where the glass members and the adhesive film are alternately disposed; and decorative layers provided on surfaces of the at least two glass members facing toward the at least one adhesive film. At least two of the decorative layers independently comprise an etched texture, an optical coating layer, and a pattern layer sequentially stacked, or at least two of the decorative layers independently comprise the etched texture, the pattern layer, and the optical coating layer sequentially stacked.

First claim

1 . A laminated glass, comprising:
at least two glass members and at least one adhesive film disposed in a stacked manner, where the glass members and the adhesive film are alternately disposed; and decorative layers provided on surfaces of the at least two glass members facing toward the at least one adhesive film, wherein: at least two of the decorative layers independently comprise an etched texture, an optical coating layer, and a pattern layer sequentially stacked, or at least two of the decorative layers independently comprise the etched texture, the pattern layer, and the optical coating layer sequentially stacked.

2 . The laminated glass according to claim 1 , wherein:
the at least two glass members comprise a first glass member and a second glass member, the at least one adhesive film comprises a first adhesive film, the first glass member, the first adhesive film, and the second glass member are stacked from bottom to top, and the decorative layers are provided on an upper surface of the first glass member and a lower surface of the second glass member.

3 . The laminated glass according to claim 1 , wherein:
the at least two glass members comprise a first glass member, a second glass member, and a third glass member, the at least one adhesive film comprises a first adhesive film and a second adhesive film, the first glass member, the first adhesive film, the second glass member, the second adhesive film, and the third glass member are stacked from bottom to top, the decorative layers are provided on an upper surface of the first glass member, a lower surface of the second glass member, an upper surface of the second glass member, and a lower surface of the third glass member.

4 . The laminated glass according to claim 1 , wherein a thickness of each of the at least two glass members is in a range from 0.2 mm to 0.5 mm; and a thickness of each of the at least one adhesive film is in a range from 0.025 mm to 0.1 mm.

5 . The laminated glass according to claim 1 , further comprising a base color layer, wherein the base color layer is disposed on a lower surface of a lowermost glass member of the at least two glass members.

6 . The laminated glass according to claim 1 , wherein the etched texture is formed by etching a surface of the at least two glass members.

7 . The laminated glass according to claim 1 , wherein the etched texture comprises at least one of a pattern texture, a striped texture, a matte texture, or a gradient texture.

8 . The laminated glass according to claim 1 , wherein the optical coating layer is transparent or has a predetermined color.

9 . The laminated glass according to claim 1 , wherein the pattern layer is formed from ink, and orthographic projections of two pattern layers on the at least two glass members are at least partially non-overlapping.

10 . The laminated glass according to claim 1 , wherein a pattern layer in an uppermost decorative layer of the decorative layers comprises at least one of a mirror silver logo or a window pattern.

11 . The laminated glass according to claim 1 , wherein a material forming the at least one adhesive film comprises at least one of polyvinyl butyral, an ethylene-methacrylate copolymer, an ionic film, an ethylene-vinyl acetate copolymer, thermoplastic polyurethane elastomer rubber, or propylene oxide.

12 . An electronic device housing, wherein at least a part of the electronic device housing is formed of a laminated glass, wherein the laminated glass comprises:
at least two glass members and at least one adhesive film disposed in a stacked manner, where the glass members and the adhesive film are alternately disposed; and decorative layers provided on surfaces of the at least two glass members facing toward the at least one adhesive film, wherein: at least two of the decorative layers independently comprise an etched texture, an optical coating layer, and a pattern layer sequentially stacked, or at least two of the decorative layers independently comprise the etched texture, the pattern layer, and the optical coating layer sequentially stacked.

13 . The electronic device housing according to claim 12 , wherein:
the at least two glass members comprise a first glass member and a second glass member, the at least one adhesive film comprises a first adhesive film, the first glass member, the first adhesive film, and the second glass member are stacked from bottom to top, and the decorative layers are provided on an upper surface of the first glass member and a lower surface of the second glass member.

14 . The electronic device housing according to claim 12 , wherein:
the at least two glass members comprise a first glass member, a second glass member, and a third glass member, the at least one adhesive film comprises a first adhesive film and a second adhesive film, the first glass member, the first adhesive film, the second glass member, the second adhesive film, and the third glass member are stacked from bottom to top, the decorative layers are provided on an upper surface of the first glass member, a lower surface of the second glass member, an upper surface of the second glass member, and a lower surface of the third glass member.

15 . The electronic device housing according to claim 12 , wherein a thickness of each of the at least two glass members is in a range from 0.2 mm to 0.5 mm; and a thickness of each of the at least one adhesive film is in a range from 0.025 mm to 0.1 mm.

16 . The electronic device housing according to claim 12 , wherein the laminated glass further comprises a base color layer, wherein the base color layer is disposed on a lower surface of a lowermost glass member of the at least two glass members.

17 . The electronic device housing according to claim 12 , wherein the etched texture is formed by etching a surface of the at least two glass members.

18 . The electronic device housing according to claim 12 , wherein the etched texture comprises at least one of a pattern texture, a striped texture, a matte texture, or a gradient texture.

19 . The electronic device housing according to claim 12 , wherein the optical coating layer is transparent or has a predetermined color.

20 . The electronic device housing according to claim 12 , wherein the pattern layer is formed from ink, and orthographic projections of two pattern layers on the at least two glass members are at least partially non-overlapping.
