摘要:
A method for producing an air bag base fabric which has a silicone rubber coating layer on at least one surface of a substrate is provided. The silicone rubber coating layer is prepared by curing a liquid silicone rubber coating composition having the low viscosity required in the coating and excellent adhesion to the air bag base fabric. An air bag base fabric produced by this method is also provided. In this method, an air bag base fabric is produced by preliminarily treating at least one surface of the textile fabric with an organosilicon compound containing an epoxy group and an alkoxy group bonded to a silicon atom in one molecule to prepare a substrate fabric containing about 0.01 to 5 parts by weight of the organosilicon compound, and coating and curing the liquid silicone rubber coating composition of particular formulation on the substrate.

A liquid silicone rubber coating composition that is ideal for forming a coating on an air bag is provided. The composition includes: (A) an organopolysiloxane containing two or more alkenyl groups bonded to silicon atoms within each molecule, (B) an organohydrogenpolysiloxane containing at least two silicon atom-bonded hydrogen atoms within each molecule, (C) an addition reaction catalyst, (D) a finely powdered silica with a specific surface area of at least 50 m2/g, (E) an organosilicon compound containing an epoxy group and a silicon atom-bonded alkoxy group within each molecule, and (F) a compound represented by a general formula: Al(OH)(OCOR)2 (wherein, R represents identical or different, unsubstituted or substituted monovalent hydrocarbon groups of 1 to 20 carbon atoms). Leakage of the inflator gas when the air bag is in an inflated state is suppressed, enabling production of an air bag that exhibits excellent sustainability of the inflation period.

Provided is a liquid silicone rubber coating composition, including predetermined quantities of (A) an organopolysiloxane containing 2 or more Si atom-bonded alkenyl groups, (B) an organohydrogenpolysiloxane containing 2 or more SiH groups, (C) an addition reaction catalyst, (D) a finely powdered silica with a specific surface area of at least 50 m2/g, (E) an organosilicon compound containing an epoxy group and a Si atom-bonded alkoxy group, and (F) an oxyzirconium compound. The composition is useful for producing a silicone rubber coating layer on the substrate surface of a curtain air bag. The air bag suppresses leakage of the inflator gas, thus enabling the inflation time to be sustained for a satisfactory period.

Provided is a liquid silicone rubber coating composition, including predetermined quantities of (A) an organopolysiloxane containing 2 or more Si atom-bonded alkenyl groups, (B) an organohydrogenpolysiloxane of a specific structure containing 2 or more SiH groups, (C) an addition reaction catalyst, (D) a finely powdered silica with a specific surface area of at least 50 m2/g, (E) an organosilicon compound containing an epoxy group and a Si atom-bonded alkoxy group, and (F) a titanium compound and/or a zirconium compound. The coating composition exhibits excellent adhesion to an air bag base fabric and, therefore, is useful for producing a curtain air bag having a silicone rubber coating layer including a cured product of such a composition on at least one surface of the base fabric.
