Abstract

A resin composition is provided which is used as a vehicle part, for example, an intake hose material for a vehicle turbo to provide excellent durability, heat resistance, and elongation. The resin composition of the intake hose material for the vehicle turbo of the present invention includes polyamide 6, polypropylene, and an olefin elastomer rubber. The resin composition further includes an antioxidant, a heat resistance stabilizer, a lubricant, and a master batch. Accordingly, the resin composition of the present invention provides substantially improved durability, heat resistance, and elongation. In addition, mechanical rigidity and pressure resistant and cold resistant properties of the resin composition is improved, and simultaneously, a weight reduction is feasible and manufacturing cost is reduced.

First claim

What is claimed is:

1. A resin composition, comprising:
polyamide 6;
polypropylene;
an olefin elastomer rubber; an olefin-based lubricant; and
an antioxidant comprising a phenol-based antioxidant and a phosphorus based antioxidant,
wherein a content of polyamide 6 is of 30 to 50 wt % based on the total weight of the resin composition,
wherein a content of polypropylene is 10 to 20 wt % based on the total weight of the resin composition,
wherein a content of the olefin elastomer rubber is 30 to 50 wt % based on the total weight of the resin composition, wherein a content of the olefin-based lubricant is 0.2 to 0.5 wt % based on the total weight of the resin composition.

2. The resin composition of claim 1 , wherein the polyamide 6 has a glass transition temperature of about 47° C., a heat distortion temperature (HDT) of about 75° C., and a melting temperature of about 220° C.

3. The resin composition of claim 1 , wherein a content of the antioxidant is of 0.3 to 0.5 wt % based on the total weight of the resin composition.

4. The resin composition of claim 1 , further comprising:
a sulfur-based heat resistance stabilizer.

5. The resin composition of claim 4 , wherein the heat resistance stabilizer comprises thioether or derivatives thereof.

6. The resin composition of claim 4 , wherein a content of the sulfur-based heat resistance stabilizer is of 1 to 2 wt % based on the total weight of the resin composition.

7. A vehicle part that comprises a resin composition of claim 1 .

8. The vehicle part of claim 7 is an intake hose.
