发明名称 FIBER-REINFORCED RESIN COMPOSITION AND MOLDED OBJECT THEREOF
摘要 Long-fiber-reinforced thermoplastic resin particles and a blend thereof are provided, wherein the opening property of the reinforcing fibers during molding is good, and a molded body exhibiting an excellent appearance and having high mechanical strength is obtained. The particles (A) contains a thermoplastic resin (A1), produced by using a metallocene catalyst, a modified polyolefin resin (A2) modified with an unsaturated carboxylic acid or a derivative thereof, and reinforcing fibers (A3) and satisfy the following requirements (1) to (5); (1) the amount of modification of the unsaturated carboxylic acid or a derivative thereof is 0.01 to 2 percent by weight in 100 percent by weight of the total of (A1) and (A2); (2) (A1) and (A2) constitute 20 to 70 percent by weight in 100 percent by weight of the total of (A1), (A2), and (A3); (3) (A3) constitutes 30 to 80 percent by weight in 100 percent by weight of the total of (A1), (A2), and (A3); (4) when 25 g of (A) is encapsulated in a 20-L chamber and is stood at 65°C for 1 hour, the amount of acetaldehyde dissipated from (A) is 3.0 µg/m 3 or less; and (5) the melting point of the resin component in (A) is 150°C or higher.
