Embodiment 1

[0103] (1) Preparation of dispersion

[0104] 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO), 0.98 parts by weight of ITO particles (manufactured by Mitsubishi Materials), and naphthalocyanine compound (copper naphthalocyanine compound, manufactured by Fujifilm) "FF IRSORB203") 0.0182 parts by weight were mixed, and after adding a phosphate compound as a dispersant, the mixture was mixed with a horizontal bead mill to obtain a mixed liquid. Then, 0.1 parts by weight of acetylacetone was added to the mixed liquid under stirring to prepare a dispersion liquid. Among them, the content of the phosphate compound is adjusted to 1 / 10 of the content of the heat-insulating particles.

[0105] (2) Production of interlayer film for laminated glass

[0106] With respect to 100 parts by weight of polyvinyl butyral resin (degree of butyralization 68.5 mol%, hydroxyl content 30.5 mol%), the entire amount of the obtained dispersion is added, and the mixture is sufficiently melt...

Embodiment 2～13 and comparative example 1～4

[0110] Like Example 1, the dispersion liquid, the interlayer film for laminated glass, and the laminated glass were produced, except that the composition (mixing amount) of the interlayer film for laminated glass was changed as shown in Table 1 below. In addition, in Examples 2-13 and Comparative Examples 1-2, 4, the content of a phosphoric acid ester compound was adjusted to 1 / 10 of the content of heat insulating particles. In Comparative Example 3, no phosphate compound was used.

[0111] (Evaluation of Examples 1 to 13 and Comparative Examples 1 to 4)

[0112] (1) Measurement of Tts and Tds (Solar Direct Transmittance)

[0113] The aforementioned Tts and the aforementioned Tds of the obtained laminated glass were measured according to the measuring method prescribed by the aforementioned Cool Cars Standards, which is scheduled to be introduced. Specifically, the above-mentioned Tts and the above-mentioned Tds were measured with a spectrophotometer ("U-4100" manufactured by Hitac...

Embodiment 14

[0124] The dispersion, the interlayer film for laminated glass, and the laminated glass were produced as in Example 1. The difference is that the ITO particles (manufactured by Mitsubishi Materials Co., Ltd.) are changed to IZO particles, and the composition of the interlayer film for laminated glass (mixing amount) The changes shown in Table 1 below were made. In addition, in Example 14, the content of the phosphoric acid ester compound was adjusted to 1 / 10 of the content of the heat insulating particles.

Abstract

Disclosed is an intermediate film for laminated glass, which is capable of providing laminated glass that has high heat shielding properties and high visible light transmittance. Specifically disclosed is an intermediate film (2) for laminated glass, which contains a thermoplastic resin, a plasticizer, heat shielding particles, and at least one kind of component selected from among phthalocyanine compounds, a naphthalocyanine compounds and anthracyanine compounds. When the content of heat shielding particles per 100 parts by weight of the thermoplastic resin is represented by content A and the content of the at least one kind of component per 100 parts by weight of the thermoplastic resin is represented by content B, the content A in the intermediate film (2) for laminated glass is within the range of 0.1-3 parts by weight and the ratio of the content A to the content B (content A / content B) is within the range of 3-2000.

Description

Technical field [0001] The present invention relates to an interlayer film for laminated glass used for laminated glass in automobiles, buildings, and the like. More specifically, it relates to an interlayer film for laminated glass that can improve the heat insulation of the laminated glass, and an interlayer film using the interlayer film for laminated glass. Laminated glass. Background technique [0002] Even if the laminated glass is damaged by an external impact, the amount of scattered glass fragments is small, and the safety is excellent. Therefore, the above-mentioned laminated glass has been widely used in automobiles, rail vehicles, airplanes, ships and buildings. The above-mentioned laminated glass is produced by sandwiching an interlayer film for laminated glass between a pair of glass plates. The laminated glass used in the openings of such vehicles and buildings is required to have high heat insulation. [0003] Infrared rays with a wavelength greater than 780nm or...
