Embodiment 1

[0194] (1) Production of interlayer film

[0195] Prepared 0.2 parts by weight of the following ethanol solution: bis(2-ethylbutyric acid) containing bis(2-ethylbutyric acid) in an amount of 25 ppm based on the content of magnesium and magnesium ions (magnesium concentration derived from the magnesium salt P of organic acid) in the obtained intermediate film ) magnesium, and an ethanol solution of magnesium bis(acetate) in an amount of 25 ppm based on the content of magnesium and magnesium ions (magnesium concentration derived from the metal salt Q of organic acid) in the obtained intermediate film. Using a horizontal bead mill, 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO), tungsten oxide particles in an amount of 0.07% by weight in 100% by weight of the obtained intermediate film, and the obtained ethanol 0.2 parts by weight of the solution were mixed to obtain a dispersion.

[0196] With respect to 100 parts by weight of polyvinyl butyral resin (PVB), ...

Embodiment 2

[0203] Except for changing the content of tungsten oxide particles to the content shown in the following Table 2 in 100% by weight of the obtained interlayer film, the interlayer film and laminated glasses A and B were obtained in the same manner as in Example 1. .

Embodiment 3

[0205] In Example 3, the intermediate film obtained in Example 2 was used. A laminated glass A was obtained in the same manner as in Example 2 except that the two sheets of green glass were changed to two sheets of transparent glass (length 30 cm x width 30 cm x thickness 2.5 mm) based on JIS R3202. In addition, the laminated glass B was obtained in the same manner as in Example 2 except that the two sheets of green glass were changed to two sheets of transparent glass (length 100 cm x width 100 cm x thickness 2.5 mm) based on JIS R3202.

Abstract

Provided is a laminated glass interlayer that has a high heat shielding performance, a high visible light transmittance, and excellent light resistance, and can thus maintain a high visible light transmittance for a long period of time. This interlayer for laminated glass has a single-layered structure or a laminated structure of at least two layers. This interlayer for laminated glass has a first layer (31). The first layer (31) comprises a polyvinyl acetal resin, a plasticizer, tungsten oxide particles, a magnesium salt of an organic acid having a branched structure and a metal salt of a C2-8 organic acid other than the magnesium salt of an organic acid having a branched structure.

Description

technical field [0001] The present invention relates to an interlayer film for laminated glass which can be used for laminated glass of automobiles and buildings, and more specifically, to an interlayer film for laminated glass capable of obtaining laminated glass with high heat-shielding properties, and an interlayer film for laminated glass using the interlayer film for laminated glass laminated glass. Background technique [0002] 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 above-mentioned laminated glass has been widely used in automobiles, rail vehicles, airplanes, ships and buildings. The above-mentioned laminated glass is manufactured by interposing an interlayer film for laminated glass between a pair of glass plates. Laminated glass used for such openings of vehicles and buildings is required to have high thermal insulation. [0003] Infrared rays with a wave...
