Abstract

This invention provides a silicone-coated fabric for airbags in which creases can be easily formed by applying heat and pressure, that can be stored compactly, and that exhibits minimal damage on the coated layer when deployed. More specifically, the invention provides a silicone-coated fabric comprising a silicone-based resin coated on one surface of a synthetic fiber woven fabric, and a thermoplastic resin adhering to the silicone-based resin-coated surface, wherein the adhesive strength between the silicone-based resin-coated surfaces is 0.01 to 10 N/cm.

First claim

The invention claimed is:

1. A silicone-coated fabric comprising
silicone-containing resin coated on one surface of a synthetic fiber woven fabric, and
a thermoplastic resin adhering to the silicone-containing resin-coated surface,
wherein the silicone-containing resin is between the thermoplastic resin and the synthetic fiber woven fabric, and the adhesive strength between silicone-containing resin-coated surfaces is 0.01 to 10 N/cm.

2. The silicone-coated fabric according to claim 1 , wherein the thermoplastic resin has a melting point of 50 to 200° C.

3. The silicone-coated fabric according to claim 1 , wherein the coating amount of the silicone-containing resin is 10 to 200 g/m 2 .

4. An airbag obtained by using the silicone-coated fabric of claim 1 .

5. The silicone-coated fabric according to claim 1 , wherein the silicone-containing resin comprises an addition polymerization silicone rubber.

6. The silicone-coated fabric according to claim 5 , wherein the silicone-containing resin comprises dimethyl silicone rubber, methyl vinyl silicone rubber, methylphenyl silicone rubber, trimethyl silicone rubber, fluorosilicone rubber, methyl silicone resin, methylphenyl silicone resin, methyl vinyl silicone resin, epoxy-modified silicone resin, acrylic-modified silicone resin, or polyester-modified silicone resin.

7. The silicone-coated fabric according to claim 1 , wherein the silicone-containing resin further comprises an adhesive aid.

8. The silicone-coated fabric according to claim 7 , wherein the adhesive aid is selected from the group consisting of amino-containing silane coupling agents, epoxy-modified silane coupling agents, vinyl-containing silane coupling agents, chloro-containing silane coupling agents, and mercapto-containing silane coupling agents.

9. The silicone-coated fabric according to claim 1 , wherein the silicone-containing resin further comprises an inorganic filler.

10. The silicone-coated fabric according to claim 9 , wherein the inorganic filler comprises silica particles.

11. The silicone-coated fabric according to claim 1 , wherein the thermoplastic resin comprises a low-density-polyethylene resin, an EVA resin, a polyamide resin, a polyester resin, a PVA resin, a polyurethane resin, a polyolefin resin, or an ionomer resin.

12. The silicone-coated fabric according to claim 1 , wherein the coating amount of the thermoplastic resin is 20 to 400 g/m 2 .

13. The silicone-coated fabric according to claim 1 , wherein the thermoplastic resin is 1% to 45% of the silicone-containing resin-coated surface.
