Problems solved by technology
[0020] However, the reinforced thermoplastic resin composition in (1) has insufficient welding strength after processing molded products
[0021] The reinforced thermoplastic resin composition in (2) has the problem that the mechanical strength other than the impact resistance decreases after processing the molded product
[0022] Reinforced thermoplastic resin compositions in (3) and (4) have insufficient impact resistance after processing molded articles
[0024] However, a reinforced thermoplastic resin composition excellent in moldability and a balance of welding strength, mechanical strength, and impact resistance of the resulting molded product has not been proposed so far.

[0271] The above-mentioned components were mixed with the compositions shown in Tables 1 to 7, and kneaded using a twin-screw extruder to obtain pellets of a reinforced thermoplastic resin composition. The resulting pellets were dried at 100° C. for 3 hours, injection molded, and moldability was evaluated. In addition, the Charpy impact strength, flexural strength, flexural modulus, welding strength, heat resistance, and the obtained molded article were measured. The evaluation results are shown in Tables 1-6.

Description
technical field [0001] The present invention relates to a thermoplastic resin composition reinforced with an inorganic filler and a molded article using the composition. [0002] This application claims priority based on Japanese Patent Application No. 2015-065828 for which it applied in Japan on March 27, 2015, and uses the content here. Background technique [0003] Thermoplastic resin compositions (for example, ABS resin, polycarbonate resin / ABS resin, polyamide resin, etc.), or the thermoplastic resin composition reinforced by inorganic filler. [0004] As a method of manufacturing a case, generally, a method of molding the thermoplastic resin composition by injection molding capable of being molded into a shape freely to a certain extent is employed. [0005] In recent years, the casings of mobile devices have been required to be thinner, to be able to withstand shocks and loads when put in bags, and to be unpainted for the purpose of cost reduction. In order to mee...
