Abstract

The invention discloses a double-sided pressure-sensitive explosive tape and a preparation method thereof. The problems such as poor adhesion and low strength of existing flexible explosives are solved. The double-sided pressure-sensitive explosive tape includes a flexible explosive layer, both sides of the flexible explosive layer are coated with pressure-sensitive adhesive layers, and release material layers are attached to the pressure-sensitive adhesive layers on at least one side. During preparation, both sides of a sheet-shaped flexible explosive are uniformly coated with pressure-sensitive adhesives, and release materials are attached to the outside of the pressure-sensitive adhesives on at least one side. The double-sided pressure-sensitive explosive tape has the advantages such ashigh adhesion, good attachment performance, good explosion effect, convenient use and operation and simple process.

Description

technical field [0001] The invention belongs to the technical field of explosives, in particular to a double-sided pressure-sensitive explosive adhesive tape and a preparation method thereof. Background technique [0002] Explosive processing of metal refers to the processing technology of using explosives as energy source to shape, surface harden, explosively form or weld metal blanks. With the development of production and the advancement of science and technology, new technologies and new processes for metal processing using explosives, a huge and cheap energy source, will continue to emerge. The forming, processing and comprehensive utilization of metal materials show an infinite picture. bright prospect. As one of the branches of explosive processing, the hardening and strengthening of metals provides the best technical means to improve the surface hardness of metals and prolong their service life. Among them, the surface hardening of high manganese steel related parts...
