According to an embodiment of the present invention, a silicone rubber composition comprises: 100 parts by weight of polyorganosiloxane represented by chemical formula 1; 10-70 parts by weight of silica; 3-15 parts by weight of polymethylsilsesquioxane; and 0.2-5 parts by weight of a surface treating agent including at least one of a fluoro group and a carbinol group. In chemical formula 1, R_1, R_2, R_3, R_4, R_5, R_6, R_7, and R_8 are selected among an alkyl group having 1-10 carbon atoms of each independently linear or branched type, an aminoalkyl group having 1-10 carbon atoms, a hydroxyalkyl group having 1-10 carbon atoms, a haloalkyl group having 1-20 carbon atoms, a cycloalkyl group having 3-15 carbon atoms, an aryl group having 6-12 carbon atoms, an aralkyl group having 7-20 carbon atoms, and an alkenyl group having 2-20 carbon atoms. Each of a, b, and c in chemical formula 1 is an integer of 1-100. The present invention can provide a silicone rubber molded article having improved life characteristics.
