experiment example 1

[0087]

[0088] A plastic test piece having a width of 5 cm x a length of 9 cm x a thickness of 2 mm was prepared from ABS resin (Techno polymer Co., Ltd., 130NP). The surface of the ABS test piece is pasted with a SBR solvent-based adhesive (Konishi, G Clear), and the fading tester (manufactured by Yasuda Seiki Seisakusho Co., Ltd., No. 5 fading tester; according to JIS K-5400) is pasted. It was irradiated for 300 hours (equivalent to being continuously irradiated by the midsummer midday sun for 325 days). Observe the surface state after irradiation. The results are shown in Table 1.

Abstract

There are provided a casing for an electronic device and an electronic device, which are free from undesirable sticking of dust due to static electricity in a plastic electronic device as well as malfunctions and failures of a built-in device such as a computer; have improved weatherability, impact resistance, and vibration-damping property; and are superior in design properties. A casing for various types of electronic devices, such as compact electronic devices, e.g., a mobile terminal (portable telephone etc.), portable gaming terminal, and portable player; a personal computer (main unit and monitor); OA devices such as electronic devices used in offices; and AV devices, such as a television, recording device, radio, printer, copier, and facsimile machine is molded with plastic and a knit / woven fabric is pasted to the plastic substrate.

Description

technical field [0001] The present invention relates to a housing for electronic equipment such as a mobile phone and a personal computer, a manufacturing method thereof, and an electronic equipment using the housing, and particularly relates to a housing made of plastic. Background technique [0002] Plastics (synthetic resins) are widely used in small electronic devices such as mobile terminals (mobile phones, etc.), portable game terminals, portable players, and personal computers (mainframes) because of their light specific gravity, excellent strength, and ease of molding into arbitrary shapes. and monitors), televisions, various video equipment, radios, printers, copiers, fax machines and other office electronic equipment such as AV equipment, OA equipment and other electronic equipment boxes (casings, casings, etc.). [0003] There are many types of plastics, and various plastics excellent in weather resistance, impact resistance, transparency, surface hardness, elasti...
