In order to improve the adhesion strength of room temperature vulanized silicone rubber （RTV） adhesive bonding JOB-9003 explosive，silica white 2^# or 4^# were used to reinforce modified silicone rubber by methyl acrylic acid or ester in situ. The structure of reinforced RTV adhesive and dispersibility of silica white in adhesive were characterized by IR and SEM. Effects of different viscosities of silicone rubber,contents of silica white on shear strength of RTV adhesive were investigated. The results show that the adhesion strength of RTV adhesive is improved greatly，when the viscosity of silicone rubber is 4 Pa·s,the shear strength of 2^# and 4^# silica white reinforced RTV adhesive bonding JOB-9003 explosive increases from 3.2 MPa to 3.52 MPa as contents of silica white change from 1.0% to 2.5%,and the reinforcement effect of 4^# silica white is better than that of 2^# silica white in evidence.
