油相材料对乳胶基质稳定性的影响
|
摘要
为了探究油相材料对乳胶基质稳定性的影响,以3种复合蜡为油相。通过测量各油相的黏度、酸值,以及高低温循环实验后各试样的析晶率,同时,基于3组乳胶基质试样的微观结构以及热分解特性,对乳胶基质的稳定性进行研究。研究表明,当油箱材料的黏度小、酸值大时不利于乳化炸药的稳定贮存,乳胶基质的热安定性较好其储存稳定性也较好。
In order to study the effect of oil phase material on stability of emulsion matrix, three kinds of composite wax as oil phase of emulsion matrix was selected. The viscosity and acid value of the oil phase material were measured, as well as the crystallization rate of each sample was measured after the high-low temperature cycling experiment. Meanwhile, based on the microstructures of three groups of latex matrix samples and thermal decomposition characteristics, the stability of emulsion matrix was studied. The study indicate that the stable storage of emulsion matrix will become worse as oil phase material with low viscosity and high acid value, and the emulsion matrix with good thermal stability is beneficial to its storage stability.
