Based on excellent properties and extensive use of rubber explosives,in this study,HTV( high temperature vulcanization) silicone rubber and RTV( room temperature vulcanization) silicone rubber were mixed as the adhesive of rubber explosive. A sheet rubber explosive which could be initiated reliably and detonated stably was prepared through studying the ratio of ingredients and preparation process. The critical thickness of the sheet rubber explosive for stable booster was 0. 4 mm,and it sformula was 85% PETN,9% HTV silicone rubber and 6% RTV silicone rubber,in which 2,4-dichlorobenzoyl peroxide and tetraethoxysilane were added additionally. Mechanical sensitivity and detonation velocity of the rubber explosive were also measured. The results show that its impact sensitivity is 32% and the friction sensitivity is 36%. The detonation velocity of the rubber explosive reaches 6850 m /s at the tablet thickness of 0. 6 mm and the density of 1. 50 g /cm3.
