Embodiment 1

[0193] (1) Production of interlayer film

[0194] Prepare a 0.19% by weight ethanol solution containing magnesium bis(2-ethylbutyrate) metal salt in an amount of 0.067% by weight in 100% by weight of the obtained interlayer film %.

[0195] Mix 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO) with the following materials: CWO particles, so that their amount in the obtained intermediate film 100% by weight is 0.035% by weight; ITO particles , so that its amount in 100% by weight of the obtained interlayer film is 0.14% by weight; a phthalocyanine compound, so that its amount in the obtained interlayer film is 0.004% by weight; After the phosphoric acid ester compound was mixed with a horizontal micro-bead mill, a dispersion was obtained. It should be noted that the content of the phosphate compound was adjusted to be 1 / 10 of the total content of the CWO particles and the ITO particles.

[0196] Add the following substances relative to 100 parts by weight of...

Embodiment 2～10 and comparative example 1～9

[0203] A single-layer interlayer film was produced in the same manner as in Example 1 except that the types and contents of the compounding components were set as shown in Tables 1 and 2 below. The types and compounding amounts of the same polyvinyl butyral resin and plasticizer as in Example 1 were set. Using the obtained interlayer film, laminated glasses A and B including the interlayer film were produced in the same manner as in Example 1.

[0204] In addition, in Comparative Example 7, when compounding the heat ray shielding agent, lanthanum hexaboride particles were compounded so that the amount in the obtained interlayer film was 0.007% by weight. In Comparative Example 8, gallium-doped zinc oxide particles were blended so that the amount in the obtained interlayer film was 0.120% by weight when blending the heat ray shielding agent. In Comparative Example 9, when blending the heat ray shielding agent, an imonium compound ("CIR-RL" manufactured by Nippon Carlit Co., Lt...

Embodiment 11

[0206] (1) Preparation of the first composition for forming the intermediate layer

[0207] Add 60 parts by weight of plasticizer triethylene glycol di-2-ethylhexanoate relative to 100 parts by weight of polyvinyl butyral resin (PVB2), and fully knead with mixing rollers to obtain The first composition of the middle layer.

[0208] (2) Preparation of the second composition for forming the surface layer

[0209] Prepare a 0.19% by weight ethanol solution containing magnesium bis(2-ethylbutyrate) metal salt in an amount of 0.067% by weight in 100% by weight of the obtained interlayer film %.

[0210]Mix 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO) with the following materials: CWO particles, so that their amount in the obtained intermediate film 100% by weight is 0.026% by weight; ITO particles , so that its amount in 100% by weight of the intermediate film obtained is 0.127% by weight; a phthalocyanine compound, such that its amount in the obtained inte...

Abstract

Provided is an intermediate film for laminated glass, which is capable of effectively improving heat shielding properties, while increasing visible light transmittance. An intermediate film (2) for laminated glass of the present invention contains a thermoplastic resin, tin-doped indium oxide particles, tungsten oxide particles and at least one compound selected from among a phthalocyanine compound, a naphthalocyanine compound and an anthracyanine compound.

Description

technical field [0001] The present invention relates to an interlayer film for laminated glass used in laminated glass for automobiles and buildings. In addition, the present invention relates to a laminated glass using the above-mentioned interlayer film for laminated glass. Background technique [0002] Even if 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 is widely used in automobiles, railway vehicles, aircraft, ships, buildings, and the like. The above-mentioned laminated glass can be produced by sandwiching an interlayer film for laminated glass between a pair of glass plates. Laminated glass used for openings of vehicles and buildings mentioned above requires high heat insulation. [0003] Infrared rays having a wavelength of 780 nm or longer than visible light have less energy than ultraviolet rays. However, infrared rays have a large ther...
