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% 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 evaluation of physical properties were prepared in the same manner as in Example 1 except that 25% 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% by weight of master batch MB3 was used instead of master batch MB1.

Abstract

The present invention provides a polypropylene composite resin composition having continuously maintained deodorizing ability and aromaticity and an automotive interior part molded using the polypropylene composite resin composition. The polypropylene composite resin composition contains: (a) a polypropylene polymer that is easy to injection mold, (b) a thermoplastic elastomer for improving impact resistance, (c) (d) phytoncide with deodorizing ability and aromaticity, (e) processing oil to prevent pyrolysis of phytoncide, and (f) for improving base resin Compatibility surfactants with phytoncide. The automotive interior parts molded by using the polypropylene composite resin composition disclosed in the present invention can provide the driver with a long-term fragrance by removing unpleasant odors derived from volatile organic compounds (VOC) and the like and maintaining the inherent fragrance of phytoncide for a long time. Provide a comfortable environment.

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. ...
