Example Embodiment

[0116] [Example 1]

[0117] As shown in Table 1, 2.5 parts by weight of (E) a carbon black masterbatch, 0.4 parts by weight of an internal lubricant (lubricant (S); HI-LUB B-50), and 1.3 parts by weight of a climate stabilizer ( UV stabilizer; LIGHT STABILITYA, UV-327-1) with 24 wt% (A-1) acrylic graft copolymer, 16 wt% (A-2) acrylic graft copolymer, 25 wt% (B-1) ) 100 parts by weight of the first aromatic vinyl-vinyl cyanide copolymer, 25 wt % of the (B-2) second aromatic vinyl-vinyl cyanide copolymer, and 10 wt % of the (C-1) acrylic resin The base resin is mixed to prepare a thermoplastic resin.

[0118] The prepared thermoplastic resin was stirred using a typical mixer and then extruded in a twin-screw extruder (L / D=29, Φ=45 mm) to prepare pellets. The prepared pellets were dried using a dehumidifying dryer at 80°C for 2 hours, followed by injection molding using a 60 oz. injection machine at a barrel temperature of 250°C and a mold temperature of 60°C to prepare 9 cm× f...

Example Embodiment

[0119] [Example 2]

[0120] As shown in Table 1, a test piece for property evaluation was prepared in the same manner as in Example 1 except that (C-2) acrylic resin having a glass transition temperature of 116°C was used instead of (C-1) acrylic resin. The following properties of the prepared samples were evaluated, and the results are shown in Table 2.

Example Embodiment

[0121] [Example 3]

[0122] As shown in Table 1, a sample for property evaluation was prepared in the same manner as in Example 1 except that the (C-1) acrylic resin was used in an amount of 20 parts by weight. The following properties of the prepared samples were evaluated, and the results are shown in Table 2.

Abstract

The present invention relates to a thermoplastic resin composition and, more specifically, to an acrylic resin composition having improved coloring property and heat resistance by comprising an acrylic graft copolymer, an aromatic vinyl-cyano vinyl-based copolymer and an acrylic resin, and thus is suitable for an automotive exterior material.

Description

technical field [0001] The present invention relates to thermoplastic resin compositions, and more particularly to acrylic thermoplastic resin compositions suitable for use in automotive exterior materials. Background technique [0002] Acrylonitrile-butadiene-styrene resin (hereinafter referred to as "ABS resin") is widely used in electrical / electronic products, automobile components, and resins for general goods. [0003] However, since the ABS resin contains a chemically unstable double bond in the rubber component of the resin, the rubber component may be aged by UV light. When placed outdoors, such ABS resins may suffer relatively severe discoloration and property deterioration over time due to poor weather resistance and light resistance, and thus are not suitable for outdoor use. In order to solve this problem, there have been proposed methods of subjecting molded articles produced using ABS resins to post-treatments such as coating and plating, or adding a large am...
