Problems solved by technology

However, since the infrared shielding filter described in Patent Document 1 is intended for use in a plasma display panel (PDP) and since the Ag tabular particles are not subject to configuration control, the filter is mainly used as an infrared shielding filter in the infrared region. light absorber rather than acting as a material that actively reflects heat rays
Therefore, when the infrared shielding filter containing the Ag plate-shaped particles is used for shielding direct sunlight, the infrared absorbing filter itself is heated due to its heat to raise the ambient temperature, so it serves as an important component of the infrared shielding material.

Embodiment

[0240] Features of the present invention are described more specifically with reference to Examples given below.

[0241] In the following examples, the materials used, the amounts used, the ratios, the details of the treatments and the procedures of the treatments can be appropriately changed or altered without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limitedly interpreted as the examples provided below.

Embodiment 1 to 4 and comparative example 5

[0283] The ratio of Plascoat Z687 and Carbodilite V-02-L2 contained in the coating solution of Comparative Example 4 was changed as shown in Table 1, while keeping the total solid weight constant, thereby manufacturing Examples 1 to 4 and Comparative Example 5 Heat ray shielding material samples.

Embodiment 5 to 8

[0287] The heat ray shielding material samples of Examples 5 to 8 shown in Table 1 were manufactured in the same manner as Comparative Example 1, except that the amount of the seed solution added in Comparative Example 1 was changed to 53 mL, and after adding the white precipitation mixed solution Then add 72mL of 0.12M NaOH aqueous solution to the reactor to replace 72mL of 0.83M NaOH aqueous solution, and change the amount of Plascoat Z687 added so that the thickness of the coating can be as shown in Table 1.

Abstract

A heat ray shielding material having a metal particle containing layer, the metal particle containing layer containing at least one metal particle and a binder, wherein the metal particle containing layer has a thickness of 10 nm to 80 nm, the metal particle containing At least 60 number % of hexagonal to circular flat metal particles, the binder in the metal particle-containing layer has a cross-linked structure derived from a cross-linking agent, and the cross-linking group density ratio is 0.3 to 30, the The heat ray shielding material has good visible light transmittance, heat shielding coefficient, scratch resistance and pencil hardness.

Description

technical field [0001] The present invention relates to a heat ray shielding material having good visible light transmittance, heat shielding property, scratch resistance and pencil hardness. Background technique [0002] In recent years, as an energy-saving measure for reducing carbon dioxide, materials that can impart heat ray shielding properties have been developed for windows of vehicles and buildings. From a heat ray shielding (solar radiant heat gain rate) point of view, heat reflective types without re-radiation are desirable, rather than indoor re-radiation with light absorption (approximately 1 / 3 of the amount of absorbed solar energy) ) heat absorption type, there have been various proposals for this. [0003] As an infrared shielding filter, a filter using Ag tabular particles has been proposed (see Patent Document 1). However, since the infrared shielding filter described in Patent Document 1 is intended for use in a plasma display panel (PDP) and since the Ag...
