Abstract

The invention discloses a PO film serving as an emulsion explosive filling film and a preparation method thereof, and belongs to the technical field of industrial explosive filling films. The PO film consists of an outer layer, a middle layer and an inner layer which are sequentially laminated, wherein the outer layer is prepared from 60-80wt% of reinforced polyethylene and 20-40wt% of butylene linear low-density polyethylene; the middle layer is mainly prepared from 20-40wt% of reinforced polyethylene and 60-80wt% of high-density polyethylene; the inner layer is mainly prepared from 20-40wt% of butylene linear low-density polyethylene, 10-30wt% of a metallocene ethylene-hexene copolymer or metallocene MLLDPE and 40-60wt% of high-density polyethylene. The invention aims to provide the PO film serving as the emulsion explosive filling film, which integrates superior performance of a PP film and a PE film, and the preparation method thereof. The PO film is used for filling an emulsion explosive.

Description

technical field [0001] The invention relates to a composite membrane, more specifically, to a PO membrane used for emulsified explosive filling membrane. The invention also relates to a preparation method of the PO membrane. Background technique [0002] Emulsion explosive is to use the effect of emulsifier to disperse the droplets of oxidant salt solution evenly in the oil-phase continuous medium containing porous substances such as dispersed air bubbles or hollow glass microspheres to form a water-in-oil emulsion-like explosive. , is a new industrial explosive developed in the 1970s. Because of its water-in-oil type, it needs to be wrapped with a film before it can be transported and used. However, due to the particularity of explosives, the requirements for the membrane are very high. However, the existing PO film cannot have good heat resistance, cold resistance and chemical stability at the same time due to unscientific formula matching, nor can it have high rigidity...
