Zusammenfassung:The invention provides an airbag base fabric coating material with water soluble resin as the matrix. A polyvinyl alcohol (PVA)-based airbag base fabric aqueous coating material is provided. Blocked polyisocyanate component (B-NCO) and liquid polyol are added, respectively, as a cross-linkage improver and a plasticizer. The B-NCO is composed of or based on a medium-molecular-weight form as a polyether-modified prepolymer, used concurrently with a low-molecular-weight form in a small amount. The base fabric coating material is applied on one or both of the sides of a cloth of the base fabric, and thus the acquired coating film is a water-insoluble coat and the coat shows excellent heat and moisture resistance (hot water resistance) and flexibility. The invention also provides airbag base fabric and a method manufacturing the same.
