US 9,803,072 B2 · Resin composition and molded article using the same

Abstract

Disclosed are a resin composition and a molded article using the same. The resin composition may be obtained by mixing a thermoplastic vulcanizate and a polyethylene resin with a thermoplastic olefin resin, a polypropylene resin, an inorganic filler and a thermoplastic rubber, and in particular, the thermoplastic vulcanizate and the polyethylene resin may be obtained from biologically obtainable materials (biomass). Thus, the resin composition may be environmentally-friendly because it does not emit offensive odor of harmful compounds due to decreased generation of carbon dioxide and volatile organic compounds unlike petroleum-based materials. Further, superior mechanical properties such as elongation, hardness, strength, etc. that cannot be achieved only with conventional biodegradable resin may be ensured, and, at the same time, processability and moldability may be improved.

Dependent claims

A resin composition comprising:

an amount of about 10-40 wt % of a thermoplastic vulcanizate;
an amount of about 20-30 wt % of a polyethylene resin;
an amount of about 30-50 wt % of a thermoplastic olefin resin;
an amount of about 1-10 wt % of a polypropylene resin;
and
an amount of about 1-10 wt % of an inorganic filler,
all the wt % based on the total weight of the resin composition,
wherein each of the thermoplastic vulcanizate and the polyethylene resin is obtained from a biomass,
wherein the thermoplastic vulcanizate comprises an oil or an ethylene propylene diene monomer (EPDM) derived from the biomass, or a mixture thereof,
wherein the polyethylene resin is one obtained by polymerizing ethylene prepared from dehydration of ethanol that is obtained from the biomass, and
wherein the thermoplastic olefin resin is in non-crosslinked states.
