Embodiment 1

[0081] exist figure 1 and figure 2 In , the explanatory diagram and perspective view are shown about the sheet glass laminated structure 10 of this invention of this invention. figure 1 (A) is a three-dimensional overall view, figure 1 (B) is a partial sectional view, figure 1 (C) is figure 1 (B) An enlarged cross-sectional view of the main part of the figure. In these figures, 20 denotes each sheet glass constituting the sheet glass laminated structure, 20a denotes a light-transmitting surface, and 30 denotes an intermediate layer interposed between the sheet glasses.

[0082] This sheet glass laminated structure 10 is, from figure 1 (A), figure 1 (B) It can be seen that three sheet glasses 20 with a thickness of 0.7 mm are stacked in an edge-aligned manner, and each sheet glass 20 has a light-transmitting surface area of ​​300 mm in length and 500 mm in width. The compositions of the three sheet glasses 20 are all expressed in terms of mass percent in terms of oxides...

Embodiment 2

[0093] In order to evaluate the performance of the plate glass laminate structure of the present invention regarding the load deformation behavior of the three-point bending test using the plate glass laminate structure, a liquid crystal having a light-transmitting surface area of ​​50 mm in length and 180 mm in width and a thickness of 0.7 mm was prepared. Sheet glass curved out-of-spec products. Since this sheet glass is stacked in 4, 5, and 6 layers, ethyl polyvinyl acetate (EVA) resin with a thickness of 0.25 mm is prepared with the same size as the sheet glass. Sheets, polyvinyl butyral (PVB) resin sheets with a thickness of 0.38mm and 0.76mm, and then sandwich the resin sheet between the laminated glass sheets to form a laminated structure of the sheet glass and the resin sheet. In addition, the laminated structure of the plate glass and the resin sheet is sandwiched by the abutting surface of the aluminum plywood that has been subjected to a curved surface treatment of ...

Embodiment 3

[0105] Next, another sheet glass laminated structure of the present invention is shown below.

[0106] Image 6A partial sectional view showing another sheet glass laminated structure 11 of the present invention. This sheet glass laminated structure 11 is a sheet glass 21 of borosilicate glass that has been strengthened, has a light-transmitting surface with a size of 300 mm x 400 mm, a plate thickness of 0.6 mm, and surface undulations in a section of 20 mm in length. In the state of exceeding 20 μm. In addition, as the intermediate layer 31 between each sheet glass, it laminated|stacked through the intermediate layer 31 which consists of the polyvinyl butyral resin sheet which disperse|distributed and mixed the translucent alumina filler, and the thickness dimension was 0.38mm.

[0107] In addition, the further structural feature of the sheet glass laminated structure 11 is that, on one side of the sheet glass laminated structure 11, the thin sheet glass (second sheet glas...

Abstract

The present invention provides a sheet glass laminate structure excellent in penetration resistance (bulletproof nature), crime prevention nature, heat shock resistance, translucency and airtightness. The sheet glass laminate structure (10) is produced by laminating at least three sheets of sheet glass (20) each having a sheet thickness of less than 1 mm with intermediate layers (30) interposed between them. When a central portion 20 mm in length including the middle point of a virtual line and opposite end portions respectively being 20 mm long from the opposite ends of the virtual line are set on the virtual line having a length equal to 50% of the maximum overall dimension of the translucent surface of the sheet glass (20) and extending in parallel with the direction of maximum overall dimension with the center of the translucent surface as its middle point, maximum variation DeltaHmax of the interval H between sheets of sheet glass opposing across the intermediate layer in connection with the central portion and the opposite end portions satisfies the following relation; 0[mu]m<DeltaHmax<20[mu]m.

Description

technical field [0001] The present invention relates to a sheet glass laminate used as a high-strength and high-toughness transmission window material for buildings or vehicles, or for electronic components, and a multi-layered sheet glass laminated with the sheet glass laminate. Glass laminated structure. Background technique [0002] Sheet glass is used in many applications due to its translucency. As window panes of various buildings or front windows of vehicles, or electronic components, such as display windows of image display devices such as liquid crystal display devices or plasma displays, and as various packages for accommodating electronic components As a window material, plate-shaped glass articles endowed with various performances are used. [0003] From such various uses, in order to achieve high Various inventions have been made so far to improve performance or overcome weaknesses. [0004] For example, in Patent Document 1, it is disclosed that sheet glass...
