Abstract

The invention relates to the field of explosive processing, and in particular relates to a fiber-reinforced rubber explosive and a preparation method thereof. The problems in the existing explosive processing technology that the mechanical properties are poor and the process is complicated and has dangerousness are solved. The fiber-reinforced rubber explosive is composed of the following raw materials in parts by mass: 5-20 parts of rubber, 55-90 parts of high explosives, 2-5 parts of chopped fibers and 3-10 parts of additives. The invention has the beneficial effects that the prepared explosive has excellent mechanical properties and adjustable detonation velocity and detonation output energy; and with the adoption of recyclable rubber powder and chopped fibers, recycling of wastes is realized; the fiber-reinforced rubber explosive has the advantages that the production process is simple, the components are uniformly mixed, and batch production can be realized; and the fiber-reinforced rubber explosive is used in the explosion working industry and can also be used in other special industries, particularly operations in low-temperature environments.

Description

technical field [0001] The invention relates to the field of explosive processing, in particular to a fiber-reinforced rubber explosive and a preparation method thereof. Background technique [0002] As a material with good flexibility and processability at room temperature, rubber explosive is widely used in processing fields such as explosive hardening and explosive welding. [0003] At present, the formulations of conventional rubber explosives generally have poor tensile strength and hardness, and are not stable enough in oil resistance, acid resistance, alkali resistance, salt resistance, and low temperature resistance. [0004] The conventional preparation process generally adopts a wet method, that is, adding explosives and other additives to a natural rubber aqueous solution or a solution using other solvents, mixing and stirring, drying (airing) and other processes. The process is complicated and the uniformity is not easy to control. And since the rubber is at -20...
