Embodiment 1

[0337] Preparation of the first resin layer:

[0338] The following components were mixed and fully kneaded with a mixing roll to obtain a composition for forming the first resin layer.

[0339] Polyvinyl acetal resin (average degree of polymerization 1700, hydroxyl content 30.5 mol%, degree of acetylation 1 mol%, degree of acetalization 68.5 mol%) 100 parts by weight

[0340] 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO)

[0341] Tinuvin326 (2-(2'-hydroxy-3'-tert-butyl-5-methylphenyl)-5-chlorobenzotriazole, manufactured by BASF Corporation in an amount of 0.2% by weight in the obtained resin layer Tinuvin326")

[0342] BHT (2,6-di-t-butyl-p-cresol) in an amount of 0.2% by weight in the obtained resin layer

[0343] The obtained composition for forming the first resin layer was extruded using an extruder to obtain a first resin layer having the thickness and wedge angle shown in Table 1 below.

[0344] Preparation of the second resin layer:

[0345] T...

Embodiment 2～15 and comparative example 1～19

[0359] Laminated glass was obtained in the same manner as in Example 1, except that the configuration of the interlayer film was changed as shown in Tables 1 to 6 below.

[0360] In Comparative Examples 1 to 11 and 15 to 17, no infrared reflection layer was used.

[0361] It should be noted that, in Examples 2 to 15 and Comparative Examples 1 to 19, in the first and second resin layers, the same ultraviolet shielding agent and antioxidant as in Example 1 were used in 100% by weight of the obtained resin layer. The same mixing amount as in Example 1 was mixed. The heat-shielding substance was mixed in the compounding quantity shown to the following Tables 1-6 with respect to 100 weight% of the obtained resin layer. In addition, in Examples 8 to 15 and Comparative Examples 15 to 19, the light emitting material in the amount indicated in the table was used in the obtained resin layer.

Abstract

Provided is a laminated glass that is served as a head up display, whereby it becomes possible to prevent the thermal deterioration of a light source device for irradiating the laminated glass with light for image display use. The laminated glass according to the present invention is a head up display, has a wedge angle of 0.1 mrad or more or contains a light-emitting material, and is provided with a first laminated glass member, a second laminated glass member and an intermediate film, wherein the first laminated glass member is arranged on a first surface side of the intermediate film, the second laminated glass member is arranged on a second surface side, which is opposed to the first surface, of the intermediate film, the solar transmittance of the laminated glass is 50% or less, and the solar reflectance of the laminated glass is 15% or more.

Description

technical field [0001] The invention relates to laminated glass as a head-up display. Furthermore, the present invention relates to a head-up display system including laminated glass. Moreover, this invention relates to the manufacturing method of the head-up display system provided with laminated glass. Background technique [0002] In general, even when laminated glass is damaged by external impact, the amount of glass shards scattered is small, and it is excellent in safety. Therefore, the laminated glass is widely used in vehicles, railway vehicles, spacecraft, ships, buildings, and the like. The laminated glass is produced by interposing an interlayer film for laminated glass between a pair of glass plates. Laminated glass used in openings of such vehicles and buildings requires high heat insulation. [0003] In order to improve heat insulation, an interlayer film provided with an infrared reflection layer may be used. The following Patent Document 1 discloses an i...
