[0101] [Manufacture of polymer-based dispersant-treated ITO]

[0102] In 100 g of 15 mass % ITO toluene dispersion (manufactured by C.I. Chemical Industry Co., Ltd., ITO average particle diameter: 30 nm), 230 g of 20 mass % PMMA toluene solution was added to make polymethyl methacrylate (PMMA) relative to 1 part by mass of ITO was 3 parts by mass, mixed and stirred at room temperature (25° C.), and then heated and concentrated at 120° C. to obtain a viscous liquid. Then, after drying, it was pulverized to obtain 60 g of ITO treated with PMMA.

Abstract

Provided are a polycarbonate resin composition including the following substances in a specific proportion: a polycarbonate, a fine particle of antimony-doped tin oxide (ATO) treated with a polymeric dispersant and/or a fine particle of tin-doped indium oxide (ITO) treated with a polymeric dispersant, and a reactive silicone compound having one or more alkoxy groups and a phenyl group in a molecule thereof, and a molded plate formed by subjecting the polycarbonate resin composition to an injection molding or an extrusion molding. That is, the polycarbonate resin composition which shields a mid-infrared region and is excellent in transparency and thermal stability and the molded plate obtained therefrom are provided.

Description

technical field [0001] The present invention relates to a polycarbonate resin composition and a molded sheet thereof. More specifically, it relates to shielding the mid-infrared region, has excellent thermal stability and transparency, and is suitable for building materials (exterior), resinous windows, electricity, and electronics. A polycarbonate resin composition for window parts and its formed sheet. Background technique [0002] A film or sheet is known which can prevent temperature rise due to sunlight, infrared lamps, etc. by effectively cutting off infrared rays. [0003] Polycarbonate is excellent in impact resistance, heat resistance, and transparency, and is widely used as transparent plates such as building materials, and a transparent plate in which an infrared absorbing material is mixed with polycarbonate is known. [0004] However, since this kind of transparent plate has deterioration of the resin caused by the infrared absorbing material or the deteriorati...
