In this thesis, three traditional methods had been summarized in producing water gel explosives. Their advantages and disadvantages had been analyzed. On the basis of them, a new process was proposed, which could make the best use of energy. Thus not only could we raise the rate of production, but also could improve the safety performance.There were few differences on bursting properties and safety performance.among the four products, which proved the new process to be available. Optimizing the key parameters of the new process on production, the ratio between the mass of adhesive and the amount of crosslinking agent was 0.09/0.11, pH value between 5.1 and 5.3 and the crosslinking temperature between 20 and 40 degree Celsius.Explosion temperature, calculated by theory, means the highest temperature detonation product could reach by the blasting heat. New formulas were designed by adding different amount of potassium chloride in order to reduce the explosion temperature and reach the purpose of safety use. Simultaneously, guarantee that bursting properties and safety performance should not be reduced by a wide margin, which should still meet the need of GB19084-2000.The two explosives, obtained from the new and the traditional formula, were detected by DSC and TG separately. DSC curves were processed via Kissinger method and TG curves were dealt with by Flynn-Wall-Ozawa means, which could achieve their own activation energy and onset decomposition temperature. According to above results, we got the conclusion that the new formula was safer than the traditional formula. So it provided something useful for us to store the products safely.
