The present invention relates to a polyketone resin composition prepared by mixing a glass fiber, inorganic filler, a mineral reinforcing agent and the like with a polyketone terpolymer comprising a repeat unit represented by general formulae (1) and (2) below, wherein the composition has excellent impact resistance, elastic modulus and property maintenance after water absorption, and thus is applicable to industrial components such as masks, pipe holders, transmission brackets, bumper brackets, junction boxes for automobiles, wheel rims for automobiles, brackets for connecting power lines, covers of electronic equipment, glasses frames, air intake manifolds for automobiles, carriers for front end modules of automobiles, bezels for headlamps of automobiles, housings of interior lights, ashtrays for automobiles, multi-function switches for automobiles, speaker grills for automobiles, headrest guides for automobiles, navigation pedestals for automobiles, side moldings for automobiles, hose connectors, stem bolts for air conditioners, etc.: -[-CH2CH2-CO]x- (1) -[-CH2-CH(CH3)-CO]y- (2) Also, the present invention relates to a composition in which an amorphous semi-aromatic polyamide and polyester are blended as a polyketone polymer, wherein the polyketone composition enhances flexural properties, resistance to humidity, and dimension stability in use as industrial plastic over prior thermoplastic materials. In addition, the present invention relates to a lower housing of a polyketone laptop computer prepared by injection molding the polyketone composition and, more particularly, to a lower housing of a laptop computer having excellent flexural modulus and low-temperature impact strength, prepared by injection molding a polyketone blend comprising a linear alternative polyketone polymer, a glass fiber, a phosphorous-based flame retardant, and nylon 6I. |
