摘要

摘要: 为了探究棉籽油质量分数对现场混装乳胶基质的流变特性及抗振动性能的影响，制备了不同质量分数棉籽油的现场混装乳胶基质样品。采用旋转流变仪、HY-5A型回旋调速振动器、水溶法研究了现场混装乳胶基质的流变特性以及抗振动性能。结果表明：当棉籽油的质量分数不大于2.5%时，随着棉籽油质量分数的增大，现场混装乳胶基质的黏度逐渐增大，在现场混装车管道的温度环境下，乳胶基质的黏度均能满足泵送要求，弹性模量和内聚力逐渐变大后基本不变，抗振动性能先增大后变小；当棉籽油的质量分数为2.0%时，抗振动性能最佳。

Abstract: To investigate the influence of cottonseed oil mass fraction on the rheological properties and anti-vibration performance of site-mixed emulsion explosive matrix, samples of site-mixed emulsion explosive matrix with different cottonseed oil mass fractions were prepared. A rotational rheometer, HY-5A rotary speed-regulating vibrator, and water dissolution method were used to study the rheological properties and anti-vibration performance of the site-mixed emulsion matrix. The results show that when the mass fraction of cottonseed oil is not more than 2.5%, the viscosity of the site-mixed emulsion matrix increases gradually. In terms of the temperature environment of the pipeline of on-site mixing trucks, the viscosity of the emulsion matrix can meet the pumping requirements. The elastic modulus and cohesion increase gradually and then remain nearly stable. The anti-vibration performance first increases and then decreases, and when the cottonseed oil mass fraction is 2.0%, the anti-vibration performance is the best.
