[0099] (1) Raw materials used

[0100] (A component)

[0101] PC: Polycarbonate resin powder with a molecular weight of 24,200 obtained by the following manufacturing method

[0102] A three-section six-blade stirrer and a reflux cooling pipe are installed on the reaction vessel with a baffle. 45.6 parts of bisphenol A, 2.78 mol % of p-tert-butylphenol relative to bisphenol A, 265 parts of dichloromethane, and 200 parts of water were added to the reaction container, and nitrogen purging was performed to remove oxygen in the reaction container. . In addition, in this step, the content of the reaction vessel was less than 80% of the capacity of the vessel. Next, about 80 parts of an aqueous solution for supplying 0.09 parts of sodium dithionite and 21.8 parts of sodium hydroxide was supplied to the suspension, and bisphenol A was dissolved at 15°C. 23.35 parts of phosgene were supplied to this mixture over 30 minutes with stirring. Then, 0.016 parts of triethylamine (0.08 m...

Abstract

A resin composition comprising: (A) 100 parts by weight of a polycarbonate resin (component (A)); (B) 0.0001-1 part by weight of composite tungsten oxide microparticles (component (B)) represented by general formula: MxWyOz [wherein M represents an element selected from among H, He, an alkali metal, an alkaline earth metal, a rare earth element, Mg, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Al, Ga, In, Tl, Si, Ge, Sn, Pb, Sb, B, F, P, S, Se, Br, Te, Ti, Nb, V, Mo, Ta, Re, Be, Hf, Os, Bi and I; and x, y and z represent numerical values satisfying the requirements: 0.01=x=1, 0.001=x / y=1 and 2.2=z / y=3.0]; and (C) 0.01-1 part by weight of a benzotriazine-based ultraviolet light-absorbing agent (component (C)) having a 5% weight loss temperature, as determined by TGA (thermogravimetric analyzer), of 250 DEG C or higher.

Description

technical field [0001] The present invention relates to a resin composition containing a polycarbonate resin and an inorganic material having infrared shielding properties, and a molded article composed of the resin composition. Background technique [0002] Humans feel hot when light having a wavelength in the infrared region is irradiated on human skin. Therefore, it is necessary to block many light in the infrared wavelength region in window materials for automobiles, window materials for buildings, and the like. At the same time, it is desired that the window member transmit wavelengths in the visible light region as much as possible to secure a view. In other words, by using a material that blocks infrared rays and transmits visible light, it is possible to produce a high-transmittance window member that lowers the perceived temperature to reduce energy consumption of air conditioners and the like. Furthermore, in recent years, due to environmental concerns and technol...
