Abstract

A resin composition for an optical part, which contains (A) a polyarylene sulfide, (B) a modified polyphenylene ether, (C) a non-fibrous filler and (D) a fibrous filler, and which may further contain (E) a non-crystalline resin having a glass transition temperature of 180 DEG C. or higher and / or (F) a coupling agent. The optical axis deviation of optical parts such as an optical pickup, an optical housing, etc., formed by molding this resin composition for an optical part is small, so that they can be used in laser-applied OA machines, and the like.

Description

technical field [0001] The present invention relates to a resin composition for optical components and an optical component. In more detail, it is related with the resin composition for optical components, such as OA equipment using a laser, and an optical component. Background technique [0002] In the past, optical components such as optical pickups such as CDs and DVDs, high-speed color copiers, high-speed color laser beam printers (LBP) and other optical system housings (bases) can be made of metals such as aluminum and zinc by die-casting. However, in recent years, due to the increasing demand for cost reduction and weight reduction of products, these resins have been studied and gradually replaced. At this time, as the resin material, according to the function of each optical part, dimensional accuracy and dimensional stability during molding (injection molding), moldability (fluidity), mechanical strength, rigidity, environmental resistance (heat, Humidity, chemical...
