Abstract
Gelled explosive compositions of matter based on inorganic oxygen releasing salt material and comprising from 0 to 5% w/w of water, from 0.1 to 5% w/w of gum and from 1 to 30% w/w of an amine which in liquid form is capable of solvating said gum.
Claims15
A gelled explosive composition which is essentially non-aqueous comprising firstly from 50 to 90% w/w of inorganic oxygen releasing salt material selected from the group consisting of the nitrate, chlorate and perchlorate of the group consisting of the alkali metals, the alkaline earth metals and ammonium;
- secondly from 0 to 5% w/w of water;
- thirdly from 0.1 to 5% w/w of gum selected from the group consisting of galactomannan gums and derivatives thereof;
- and fourthly as a solvating agent for said gum from 1 to 30% w/w of an amine in liquid from.
A process for manufacturing a gelled explosive composition which process comprises reacting from 0.1 to 5 parts by weight of gum selected from the group consisting of galactomannan gums and derivatives thereof with from 1 to 30 parts by weight of a solvating amine in liquid form in admixture with from 50 to 90 parts by weight of at least one inorganic oxygen releasing salt material selected from the group consisting of the nitrate, chlorate, and perchlorate of the group consisting of the alkali metals, the alkaline earth metals and ammonium.
