Embodiment 1

[0062] Example 1. Preparation of composite resin samples using masterbatch

[0063] 65 parts by weight of polypropylene polymer, 10 parts by weight of thermoplastic elastomer and 25 parts by weight of the MB1 masterbatch prepared in the preparation example were physically mixed and extruded at 180-210 °C by using a twin-screw extruder with a diameter of 40 mm. Extruded below to prepare pellets. The prepared pellets were injection molded into samples at 180-210°C to evaluate physical properties.

Embodiment 2

[0064] Example 2. Preparation of Composite Resin Samples Using Masterbatch

[0065] Samples for evaluating physical properties were prepared in the same manner as in Example 1 except that 25 parts by weight of master batch MB2 was used instead of master batch MB1.

Embodiment 3

[0066] Example 3. Preparation of Composite Resin Samples Using Masterbatch

[0067] Samples for evaluation of physical properties were prepared in the same manner as in Example 1 except that 25 parts by weight of master batch MB3 was used instead of master batch MB1.

Abstract

A polypropylene composite resin composition with continuously maintained deodorizing capability and aromaticity and an automotive interior part molded using the polypropylene composite resin composition are provided herein. The polypropylene composite resin composition contains: (a) an easily injection moldable polypropylene polymer, (b) a thermoplastic elastomer for improving impact resistance, (c) a platy inorganic filler surface-treated with an organosilane having affinity for a phytoncide, (d) a phytoncide having deodorizing capability and aromaticity, (e) a processing oil preventing pyrolysis of the phytoncide, and (f) a surfactant for improving the compatibility between the base resin and the phytoncide at specific compositional ratios. The automotive interior part molded using the polypropylene composite resin composition disclosed herein provides a pleasant environment for drivers by removing the offensive odor from volatile organic compounds (VOCs), etc. and maintaining the intrinsic scent of the phytoncide for a long time.

Description

technical field [0001] The present invention relates to a polypropylene composite resin composition having mechanical properties sufficient for use in automotive interior parts and having continuously maintained deodorizing ability and aroma. Background technique [0002] Articles formed from polymeric materials have their own unpleasant smell which also leads to quality problems. A large number of pollutants such as volatile organic compounds (VOCs) such as benzene, formaldehyde, toluene, xylene, acetaldehyde, etc. are emitted from the interior parts of newly purchased automobiles. Volatile organic compounds (VOCs) produce unpleasant odors even at low concentrations, and are also harmful to the environment and human body, causing leukemia, chromosomal aberrations, central nervous system disorders, etc. Especially for the interior parts used inside the car and isolated from the outside, the damage caused by the emission of volatile organic compounds (VOC) is very serious. ...
