Abstract

The invention provides a colloid adhesive for composite thermite as well as a preparation method and application of the colloid adhesive. The colloid adhesive for composite thermite comprises 23-30wt%of liquid nitrile rubber, 18-23wt% of an additive, 43-57wt% of diluent and 2-4wt% of a combustion improver, wherein the additive is KNO3; the diluent is collodion; the combustion improver is Mg powder; the colloid adhesive is prepared by uniformly mixing the components. The colloid adhesive is simple and convenient in preparation method and easy to operate; by adopting the colloid adhesive, composite thermite can be colloidized, expected viscosities, flowing properties and combustion performance can be met, the composite thermite has adhesion properties, plasticity and good combustion performance, furthermore conventional application modes of the composite thermite can be improved, the composite thermite can be molded without a specific mold, limits of molds can be avoided, and the application range of the composite thermite can be widened.

Description

technical field [0001] The invention relates to a colloidal adhesive, in particular to a colloidal adhesive for composite thermite and a preparation method thereof. Background technique [0002] With the development of a large number of actual combat training, the production and destruction of unexploded ordnance has always had great potential safety hazards, especially for small unexploded ordnance, due to its large application base, the number of unexploded ordnance produced is large, and it is light in weight and easy to recycle. The value is small, the range of explosion damage is small, and the shell is thin, so it is often treated by in-situ destruction. The destruction methods of conventional ammunition can be roughly divided into three categories: explosion method, combustion method and decomposition method. Generally, these three methods can only be used when the scrapped ammunition still has high safety and will not explode during transportation and handling. Howe...
