Abstract

The invention belongs to the technical field of composite plastic processing, and particularly provides a biodegradable seismic explosive column shell and a preparation method thereof. The biodegradable seismic explosive column shell provided by the invention can be automatically degraded in the environment, so that the potential safety hazard of an unexploded seismic explosive column is effectively reduced, and degradation products do not generate any negative influence on the environment; according to the seismic explosive column shell, the degradation speed of the seismic explosive column shell can be adjusted by changing the adding amount of the biomass filler, and the degradation time of the seismic explosive column shell in various environments is effectively controlled, so that the seismic explosive column shell can be applied to more scenes; the preparation method of the biodegradable seismic explosive column shell provided by the invention is simple to operate, the utilized biomass filler belongs to a renewable resource, the source is wide, the cost is low, and industrial production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of composite plastic processing, and in particular relates to a biodegradable seismic source powder shell and a preparation method thereof. Background technique [0002] At present, traditional plastics such as polyethylene and polypropylene are mostly used in the shells of seismic source charges used in the field of geological exploration in my country. When the seismic source charge fails to detonate normally during the blasting process, the explosive force will always remain explosive due to the difficulty of decomposing the traditional plastic shell in the natural environment, posing a great safety hazard. With the continuous improvement of the country's safety and environmental protection requirements for geological exploration work, the traditional plastic casing can no longer meet the safety and environmental protection requirements. [0003] In the existing technical scheme, "a biodegradable seismic...
