[0052] First, 99.90 (Example 1), 99.80 (Example 2), 99.50 (Example 3) and 99 (Example 4) parts by weight of polycarbonate resin sheets (manufactured by Reliance Industries, India) of India, The refractive index is 1.58) preheated in a preheated oven at 110 °C for 30 minutes to remove moisture, and then modified with 0.1, 0.2, 0.5 and 1 weight part of trimethylsilyl in the hopper of the injection molding machine Functionalized silica particles (available from Dow Corning Corporation (Dow Corning Corporation) "Dow VM-2270 airgel fine particles (Dow VM-2270Aerogel Fine Particles)"; average particle size range 5-15 microns; bulk density range 40-100kg / m 3 ; BET specific surface area range 600-800m 2 / g; and a porosity of about >90%). The mixture was fed into a 150 ton injection molding machine to form samples with dimensions 7 cm (length) x 2.5 cm (width) x 0.3 cm (thickness). A total of 4 samples of different compositions were formed and tested to measure their optical prop...

Abstract

A light diffusing thermoplastic resin composition comprising: (A) a transparent thermoplastic resin; and (B) organic modified functional silica particles having 5 muiotaeta to 15 muiotaeta of the average particle size and 600 m2 / g to 800 m2 / g of the BET specific surface area, wherein the amount of component (B) is 0.05 to 20 % by weight of total amount of components (A) and (B), has an excellent light diffusing property and a high total light transmittance, inhibits discoloration, when melt-processed or used.

Description

technical field [0001] The present invention relates to a light-diffusing thermoplastic resin composition, and to a light-diffusing member molded therefrom. Background technique [0002] Transparent thermoplastic resins transmit light and are used in a wide variety of applications in electrical, electronic, OA, automotive, and other fields, and resins that provide desired properties in individual applications are selected to suit the applications. When transparent thermoplastic resins are used, especially in applications such as direct-type and edge-lit type backlight units for LCD-type TVs, lighting equipment covers, switches in various equipment, etc., since the resin transmits light, it is therefore Light sources are visible. Therefore, a material having sufficient light-diffusing properties so that it does not show the shape of the light source (lamp) after molding the resin product is being sought. [0003] In conventional techniques, a method in which polymers or ino...
