Embodiment 1 to 7
[0104]
[0105] A polymer resin composition having a composition listed in Table 1 below was melted and kneaded using a twin-screw extruder (twin-screw extruder, Φ: 40 mm, L / D=40) heated to about 300° C. to prepare particles.
[0106] Specifically, the characteristics of the components listed in Table 1 and Table 2 are as follows.
[0107] *PCT resin: a resin obtained by polymerizing cyclohexanedimethanol (CHDM) and terephthalic acid (TPA) through esterification and polycondensation, and has an intrinsic viscosity (IV) of about 0.65 dL / g.
[0108] *PET resin: A resin obtained by polymerizing ethylene glycol (EG) and terephthalic acid (TPA) through esterification and polycondensation, and has an intrinsic viscosity (IV) of about 0.80 dL / g.
[0109] *Glass fiber: OCV910 (manufactured by OCV), diameter of 10 microns (μm), average length of 3 mm, and aspect ratio (L / D) of 300.
[0110] * Highly crystalline PCT resin: PCT resin with an intrinsic viscosity of 0.65 dL / g was synth...

[0117] Experimental Example 1: Adhesion
[0118] (1) NMT processing
[0119]The pores of micron or nanometer size are formed on the metal surface by an etching process, and then, the polymer resin compositions prepared in Examples 1 to 7 and Comparative Examples 1 to 4 are injected by insert injection molding In the pores, the metal and the polymer resin composition are bonded to prepare a resin-metal bonded body.
[0120] Regarding the resin-metal bonded body, according to the ASTM D638 test method, a universal testing machine (universal testing machine, UTM) was used to perform a tensile test at a crosshead speed of 5 mm / min under normal temperature and pressure conditions, and the fracture rate was measured here. Pressure, and adhesion is determined by dividing the measured pressure by the area of the metal to plastic bond.
[0121] (2) TRI processing
[0122] After forming an anodic oxide layer on the metal surface through anodic oxidation of the pretreated metal, use...
experiment Embodiment 2
[0125] Experimental Example 2: Heat Resistance
[0126] For the polymer resin compositions prepared in Examples 1 to 7 and Comparative Examples 1 to 4, according to the ASTM D638 test method, prepare samples for testing, and utilize a heat resistance tester (HDT Tester, Toyoseiki) to measure Heat resistance under the pressure of 1.82MPa.
