초록

An explosive composition is provided which comprises a mixture of a particulate low density agent and a particulate oxidising agent. The particulate low density agent is a synthetic polymeric low density agent, e.g. foamed polystyrene, which is coated with a 5 to 30 wt % of a first wetting agent. The first wetting agent comprises a first flowable carbonaceous fuel, e.g. mineral oil, and a first tackifying agent for the first flowable carbonaceous fuel. The particulate oxidizing agent is coated with a second wetting agent. The second wetting agent compris...

청구항

1. A method for making an explosive composition comprising the steps of:a) coating a particulate synthetic polymeric low density agent with from 5 to 30 wt. %, based on the low density agent weight, of a first wetting agent which comprises a first flowable carbonaceous fuel and a first tackifying agent for said first flowable carbonaceous fuel, to form a coated low density agent; b) coating a particulate oxidizing agent with a second wetting agent which comprises a second flowable carbonaceous fuel and a second tackifying agent for said second flowable c...
