Description
Technical field
The present invention relates to the surface treatment methods of explosive crystal powder, and in particular to and it is a kind of in 1,3,5- triamido -1,3,
5- trinitrobenzen crystal powders surface grafting belongs to composite material containing energy field containing the high molecular method of energy.
Background technology
1,3,5- triamido -1,3,5- trinitrobenzen crystal are a kind of typical insensitiveness crystalline materials containing energy, are filled in insensitiveness
There is important application in medicine.In practical applications, by 1,3,5- triamido -1,3,5- trinitrobenzen crystal powders are with polymerizeing
Object binder material is used in mixed way, and polymer bonding explosive is made.Due to 1,3,5- triamido -1,3,5- trinitrobenzen crystal tables
Face has hydrophily, and the polymer binder material polarity used under normal conditions is relatively low, 1,3,5- triamido -1,3,5- tri-
Nitrobenzene crystal and polymer binder material compatibility are bad, are unfavorable for the comprehensive performance of polymer bonding explosive.
The performance of composite material is heavily dependent on the surface nature of filler.Surface-functionalized is the table for improving filler
The effective way of surface properties.Generally, two class methods are included to functionalizing material surface.One kind is surface physics effect, is wrapped
Include cladding and absorption；One kind is surface chemistry, such as chemical graft, surface hydrolysis.But due to 1,3,5- triamido -1,
3,5- trinitrobenzen crystal are small molecule organic crystals, and surface does not have reactive functional group, therefore, generally inorganic material,
The surface treatment methods such as high molecular material, carbon material are in small molecule organic crystal functionalizing material surface and do not apply to.
So far, it has been developed and crystallizes cladding, spray drying cladding, in-situ polymerization cladding etc. in the plane of crystal work(containing energy
The method of energyization.Losec is reported in (Chemical Engineering Journal, 2015,268,60-66) for example, document
Support is modern, hereby alkane plane of crystal polymerize the Lauxite to be formed using formaldehyde and melamine for heisuojin or six azepine isoamyl of hexanitro
Performed polymer coats.Document (RSC Advances, 2015,5 (27):21042-21049) report is led on octogen surface
Cross the upper 1,3,5- triamido -1,3,5- trinitrobenzen crystal of method cladding of spray drying.Chinese patent
ZL201510727192.0 reports a kind of explosive crystal cladding based on Thermo-sensitive binding agent and the method for bonded pelleting, realizes
In water phase containing can crystal surface cladding.The method of these reports coats for the plane of crystal containing energy and provides important references, but because
To be the cladding of physical action, it is also necessary to further improve cladding intensity.In addition, surface covering material is the non-macromolecule containing energy
Material is unfavorable for explosive energy.Chinese patent ZL201410048053.0 is reported to be contained on aluminium powder surface by chemical bond grafting
The high molecular method of energy, using the hydroxy functional group on aluminium powder surface, is used as bridge molecule, two-step reaction exists by diisocyanate
Glycidyl azide polymer molecule on aluminium powder surface grafting.This method provides reference for grafting macromolecule containing energy.But with
This inorganic material of aluminium powder is dramatically different, 1,3,5- triamido -1,3, and 5- trinitrobenzens crystal is because there is extremely strong molecule
Interior and molecular link hydrogen bond action, the amino of plane of crystal do not have graft reaction activity substantially.
In conclusion 1,3,5- triamidos -1,3, this kind of material surface grafting and coating of 5- trinitrobenzen crystal still face
Face challenge, develop novel 1,3,5- triamidos -1,3,5- trinitrobenzens plane of crystal grafting high molecular method containing energy is to blunt
The development and application for feeling the crystalline material containing energy have important meaning.
