Environment-friendly hot-melt composition for vehicle interior material
Disclosed is an environment-friendly hot-melt composition for a vehicle interior material, the hot-melt composition including: 65 wt % to 85 wt % of an aromatic polyamide; 10 wt % to 30 wt % of an aliphatic polyamide; 1 wt % to 5 wt % of an olefinic elastomer graft-polymerized with maleic anhydride; and 0.1 wt % to 2 wt % of an antioxidant.
1. A method of manufacturing a vehicle interior material, the method comprising:
forming an adhesive layer by applying a hot-melt composition on a substrate;
cooling the adhesive layer; and
attaching a skin layer to the adhesive layer,
wherein the hot-melt composition comprises:
65 wt % to 85 wt % of an aromatic polyamide,
10 wt % to 30 wt % of an aliphatic polyamide, and
1 wt % to 5 wt % of an olefinic elastomer graft-polymerized with maleic anhydride.
2. The method of claim 1 , wherein the hot-melt composition is applied on the substrate using a coating roll.
3. The method of claim 1 , further comprising:
after forming the adhesive layer, jetting air to the substrate and the adhesive layer and inhibiting the substrate from being attached to the coating roll.
