Problems solved by technology

[0003] However, ASA resins are limited in application to moldings due to their poor coloring properties, mechanical properties, and appearance characteristics
[0004] In order to solve the above-mentioned problems, a copolymer ASA resin in which an aromatic vinyl compound and a vinyl cyanide compound are grafted onto a mixture of acrylic rubber latex with a large caliber and acrylic rubber latex with a small caliber has been proposed, but It is still limited to improve shading performance
[0005] In addition, mixing ASA (acrylonitrile-styrene-acrylate) resins with impact-reinforcing agents has also been proposed, but it is also limited in improving weather resistance and coloring properties

Embodiment 1 to 4 and comparative example 1 to 4

[0101] Each acrylic resin composition of Examples 1 to 4 and Comparative Examples 1 to 4 was prepared using each exemplary component of the composition shown in Table 1 below.

[0102] The manufacturing method includes mixing the components of the composition shown in Table 1 below; generally adding 0.1 parts by weight of a lubricant (CHOYANG HWASUNG CO., LTD, HILUB B-50), 0.02 parts by weight of an impact-reinforcing agent (Shinetsu, KF-96-100CS) and 0.5 parts by weight of carbon black (Evonik, Highblack 50L); melt and knead the resulting mixture to provide pellets. It was extruded with a twin-screw extruder having L / D=29, 45 mm diameter at a nip roll temperature of 220°C.

[0103] The parts by weight of lubricant, impact reinforcing agent and carbon black are based on 100 parts by weight of the total amount of (A) first acrylic copolymer, (B) second acrylic copolymer and (C) vinyl copolymer .

experiment example

[0105] Each of the obtained pellets was dried at 80° C. for 2 hours, and injection molded by setting a cylinder temperature of 210° C. and a molding temperature of 60° C. with an injection molding machine having an injection capacity of 6 ounces, to provide samples for evaluation of physical properties. ASTM dumbbell-shaped samples. The physical properties of the obtained samples were measured according to the following methods, and the results are shown in Table 1 below.

[0106] 1) IZOD impact strength: measured according to ASTM D256 (1 / 8" sample thickness).

[0107] 2) Weather resistance: use Minolta CM-3600D color difference meter, according to SAE J1960 conditions, measure before using ATLAS Ci5000 WOM equipment to test the weather resistance of M9cm×5cm×0.2cm sample and test the weather resistance of M9cm×5cm×0.2cm sample After 3000 hours of color difference.

[0108] 3) Gloss: measured at an angle of 60° with UGA UGV-6P DIGITAL VARIABLE GLOSS METER.

[0109] 4) Colo...

Abstract

Disclosed are an acrylic-based resin composition including (A) a first acrylic-based copolymer having a core-shell structure including a rubber having an average particle diameter of about 0.1 to about 0.30 [mu]m, (B) a second acrylic-based copolymer having a core-shell structure including a rubber having an average particle diameter of about 0.35 to about 0.6 [mu]m, (C) a vinyl-based copolymer, (D) an ultraviolet (UV) stabilizer, and (E) an UV absorber; and a molded product made using the same.

Description

technical field [0001] The present invention relates to an acrylic resin composition and a molded article using the acrylic resin composition. Background technique [0002] ASA (acrylonitrile-styrene-acrylate) resins have excellent weather resistance, light resistance, chemical resistance, heat resistance, etc., and thus are widely used in molded products such as electrical and electronic equipment, automotive exterior parts, building materials Wait. [0003] However, ASA resins are limited in application to moldings due to their poor coloring properties, mechanical properties, and appearance characteristics. [0004] In order to solve the above-mentioned problems, a copolymer ASA resin in which an aromatic vinyl compound and a vinyl cyanide compound are grafted onto a mixture of acrylic rubber latex with a large caliber and acrylic rubber latex with a small caliber has been proposed, but It's still limited to improving shading performance. [0005] In addition, mixing an...
