Problems solved by technology

However, after the core-shell graft copolymer is added, the fluidity of the polycarbonate resin becomes poor, and due to the poor fluidity, the glass fiber is damaged during extrusion and the impact resistance cannot be improved.
[0008] Moreover, since thermoplastic resins are formed from petroleum-based materials, the CO generated 2 A large amount, causing environmental pollution

Embodiment 1 to 18 and comparative example 1 to 8

[0076] The above components in the amounts shown in Tables 1 and 2 below were extruded in a common twin-screw extruder and the extruded product was made into pellet form.

experiment example

[0078] By drying the pellets prepared according to Examples 1 to 18 and Comparative Examples 1 to 8 at 100°C for 4 hours, and then using them under the conditions of a plastic temperature of 250 to 270°C and a molding temperature of 60 to 80°C A 10-ounce injection molding machine injection was used to prepare physical samples. The physical properties of these physical samples were measured by the following methods, and the measurement results are shown in Tables 1 and 2 below.

[0079] (1) Impact strength was measured according to ASTM D256 (1 / 8").

[0080] (2) The flexural hardness was measured according to ASTM D790 (2.8 mm / min).

[0081] (3) Heat distortion temperature was measured according to ASTM D648 (18.56kgf).

[0082] (4) Warpage: Inject square samples of 6"X 6"X 1 / 16" film and determine their degree of warpage after ejection.

[0083] Degree of warping: 0 (no warping) → 5 (severe warping)

Abstract

Provided is an eco-friendly polyamide resin composition, comprising: (A-1) a first polyamide resin further comprised of polyamide 11, polyamide 1010 or a combination thereof; (B) a glass fiber with a cross section ratio (aspect ratio) of 1.5 or greater; (C) a branched co-polymer graft containing a polyolefin backbone; and optionally (A-2) a second polyamide resin further comprised of repeating organic chains of 6-carbon units.

Description

[0001] related application [0002] This application is a continuation-in-part of pending International Application No. PCT / KR2010 / 007609, filed November 1, 2010 and designating the United States, publication number WO 2011 / 065678, which is hereby incorporated by reference in its entirety, and Claim priority under 35USC Section 120. This application also claims priority to Korean Application No. 10-2009-0114805 filed on November 25, 2009 with the Korean Intellectual Property Office under 35 USC Section 119, the entire disclosure of which is also incorporated herein by reference. technical field [0003] The present disclosure relates to an environment-friendly polyamide resin composition and molded articles using the composition. Background technique [0004] Generally, when a thermoplastic resin is reinforced with glass fibers, the thermoplastic resin has improved tensile strength and flexural strength while maintaining its inherent characteristics of excellent formability...
