A blasting explosive composition containing a solid inorganic oxidising salt as the oxidizer component, a hydrocarbon liquid as the fuel component, and a binding agent. The composition can also contain an ammonium nitrate based emulsion. The binding agent can increase the water resistance, or increase the sleep time, of the explosive composition, or increase the fuel oil absorbency of the solid inorganic oxidising salt. The binding agent is selected from one or more of a long chain carboxylic acid and its salts and derivatives, especially those having from 8 to 100 or preferably 10 to 50 carbon units. The binding agent may preferably be selected from one or more of: dimer acid, trimer acid, polyisobutylene succinic anhydride, oleic acid, stearic acid, sorbitan tristearate, and their salts and esters.
一种爆破炸药组合物,含有作为氧化剂成分的固体无机氧化盐、作为燃料成分的烃类液体和粘合剂。该组合物还可含有硝酸铵乳剂。结合剂可以增加炸药组合物的防水性或睡眠时间,或增加固体无机氧化盐的燃料油吸收性。结合剂可选自一种或多种长链羧酸及其盐和衍生物,特别是具有 8 至 100 个碳单位或优选 10 至 50 个碳单位的羧酸及其盐和衍生物。结合剂最好选自以下一种或多种:二聚酸、三聚酸、聚异丁烯琥珀酸酐、油酸、硬脂酸、山梨糖醇三硬脂酸酯及其盐和酯。
