The present invention is an addition-curable liquid silicone rubber composition for an airbag, which is characterized by containing: (A) at least two alkenyl groups bonded to a silicon atom in one molecule and having a degree of polymerization of 50-2,000; (B) an organohydrogenpolysiloxane having two or more hydrosilyl groups in one molecule; (C) a fine silica powder having a specific surface area of 50 m2/g or more as measured by BET method; (D) a hydrosilylation reaction catalyst; (E) an organosilicon compound having one or more functional groups selected from the group consisting of epoxy groups, isocyanate groups and (meth) acrylic groups; an organosilicon compound containing six or more alkoxy groups directly bonded to a silicon atom in one molecule. As a result, it is possible to provide: an addition-curable liquid silicone rubber composition for an airbag, which has excellent slip resistance after being applied to a base fabric for an airbag and cured; and an airbag.
本发明为一种安全气囊用加成固化型液态硅橡胶组合物,其特征在于,其含有:(A)1分子中含有2个以上键合于硅原子的烯基且聚合度为50~2,000的有机聚硅氧烷、(B)1分子中含有2个以上氢甲硅烷基的有机氢聚硅氧烷、(C)利用BET法测得的比表面积为50m2/g以上的二氧化硅微粉末、(D)氢化甲硅烷化反应用催化剂、(E)含有选自环氧基、异氰酸酯基及(甲基)丙烯酸基中的1种以上的官能团的有机硅化合物、及(F)1分子中含有6个以上直接键合于硅原子的烷氧基的有机硅化合物。由此,可提供一种在涂布于安全气囊用基布并固化后抗滑移性优异的安全气囊用加成固化型液态硅橡胶组合物及安全气囊。
