Embodiment 1

[0091] Add the rubber-modified polystyrene resin (HIPS, HG-1760S produced by Cheil Industries Inc.) of 75 parts by weight to the ratio shown in Table 1 and 25 parts by weight of Japan's Mitsubishi Engineering Plastics Co., Ltd. (MitsubishiEngineering-Plastics Corp.) Add the phosphoric acid 2,4- Di-tert-butylphenyl diphenyl ester is extruded into pellets through a traditional twin-screw extruder at a temperature range of 200-280°C. The resin pellets were dried at 80°C for 2 hours, and molded into test samples by using an injection molding machine at 180-280°C at a molding temperature of 40-80°C. Flame retardancy was measured at 1 / 8" thickness according to UL94VB. Izod impact strength (kgf·cm / cm) was measured at 1 / 8" thickness according to ASTM D-256.

Embodiment 2～3

[0093] In addition to using polycarbonate resin (product name: Panlite L-1225Grade produced by Teijin Corporation of Japan) as the base resin and using different amounts of 2,4-di-tert-butylphenyldiphenyl phosphate, according to the implementation of Examples 2-3 were carried out in the same manner as Example 1.

Embodiment 4

[0095] In addition to using a blend of polycarbonate resin (product name: Panlite L-1225 Grade produced by Japan Teijin Corporation) and ABS (g-ABS / SAN=3 / 7) as the base resin and using different amounts of phosphoric acid 2, Example 4 was carried out in the same manner as in Example 1 except for 4-di-tert-butylphenyldiphenyl ester. g-ABS is produced by Cheil Industries Inc. under the product name CHT. SAN is manufactured by Cheil Industries Inc. under the product name AP-70.

Abstract

Disclosed herein is a flame retardant, an impact modifier and a method of preparing the foregoing flame retardant and impact modifier and a thermoplastic resin composition including the flame retardant and impact modifier. The flame retardant and impact modifier are represented by the following Chemical Formula 1. The preparation method comprises: reacting a phosphorus oxychloride with 2,4-di-tert-butylphenol to prepare 2,4-di-tert-butylphenyl dichlorophosphate; and reacting 2,4-di-tert-butylphenyl dichlorophosphate with phenol to prepare a flame retardant and impact modifier of the following Chemical Formula 1. The thermoplastic resin composition comprises: 100 parts by weight of a thermoplastic resin; and 0.1 to about 30 parts by weight of a flame retardant and impact modifier represented by the following Chemical Formula 1. The flame retardant and impact modifier may improve heat resistance and flowability as well as flame retardancy and impact strength of the thermoplastic resin composition.

Description

[0001] Cross References to Related Applications [0002] This non-provisional application claims priority to Korean Patent Application 2008-64601 filed on July 3, 2008 and Korean Patent Application 2009-29478 filed on April 6, 2009, each of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a flame retardant and impact modifier, a preparation method thereof and a thermoplastic resin composition containing the same. More specifically, the present invention relates to thermoplastics having a good balance of properties such as good heat resistance and flow properties as well as flame retardancy and impact strength by using phosphate esters with specific substituents as flame retardant and impact modifiers. resin composition. Background technique [0004] In general, thermoplastic resins are capable of good formability and mechanical properties, and accordingly are widely used in the production of many electronic...
