Problems solved by technology

In the conventional laminated glass mentioned above, the light transmittance decreases when the infrared reflectance is increased, and the infrared reflectance decreases when the light transmittance is increased, so there is another problem that it is difficult to combine them.

[0192] (4-3) Preparation method of coating liquid

[0193] The method of preparing the coating solution for the high refractive index layer and the coating solution for the low refractive index layer is not particularly limited, for example, adding a water-soluble binder resin, metal oxide particles, and other additives added as needed, and stir to mix. At this time, the order of adding the water-soluble binder resin, metal oxide particles, and other additives used as needed is not particularly limited, and each component may be added sequentially while stirring, or may be added and mixed at once while stirring. If necessary, a solvent may be further used to obtain an appropriate viscosity.

[0194]In the present invention, it is preferable to form the high refractive index layer using an aqueous high refractive index layer coating solution prepared by adding and dispersing core-shell particles. In this case, the core / shell particles are preferably prepared by adding to the ...

Abstract

This laminated glass comprises: an optical film having at least one layer of an infrared reflecting layer on a transparent resin film; and a pair of glass substrates that sandwich the optical film. The infrared reflecting layer comprises a high refractive index layer which includes a first water-soluble binder resin and first metal oxide particles and a low refractive index layer which includes a second water-soluble binder resin and second metal oxide particles, the two layers being alternately laminated, and a value obtained by dividing the thermal shrinkage rate of the optical film by the thermal shrinkage rate of the transparent resin film is in the range of 1 to 3.

Description

technical field [0001] The present invention relates to laminated glass. In particular, by specifying the structure of the infrared reflective layer and the relationship between the thermal shrinkage rates of the optical film and the transparent resin film, it is possible to suppress damage to the infrared reflective layer caused by heat treatment during manufacture, and Provided is a laminated glass excellent in infrared reflectivity and light transmittance. Background technique [0002] In recent years, for the purpose of shielding the heat felt by the human skin due to the influence of sunlight entering through the window, and suppressing the operation of the air conditioner in the car to save energy, there are products with high heat insulation or heat radiation on the market. Shielding laminated glass. [0003] Generally, laminated glass is formed by disposing an optical film between a pair of glass substrates. The optical film shields the transmission of heat radiatio...
