The invention discloses a surface coating method for explosive particles. The surface coating method comprises the following steps of: (1) depositing vapor deposition substances at the surfaces of the explosive particles by utilizing a vacuum physical vapor deposition method, so as to obtain explosives coated by wax; and (2) depositing chemical vapor deposition substances at the surfaces of the explosive particles obtained in the step (1) by utilizing a vacuum chemical vapor deposition method. According to the coating method, the explosive particles are coated by a Parylene film after being coated by the wax, as the Parylene film has relatively strong high temperature resistance and can be used for further coating the explosives coated by the wax, the problem that the explosives coated by the wax cannot resist the high temperature is solved, and the explosive particles coated by the Parylene film after being coated by the wax can be used for casting the explosives or composite explosives.

The invention relates to a high-temperature thermal transfer decoration method for an abrasion-resistant aluminum honeycomb panel of rail transit interior decoration and a product. A honeycomb panel core of the aluminum honeycomb panel and two panels are combined and welded through spot welding and brazing to form the high-temperature resistant aluminum honeycomb panel; the surface of the aluminumhoneycomb panel is pretreated, then a layer of resin base powder is sprayed to the surface of the aluminum honeycomb panel through high voltage static, and the resin base powder is cured at the hightemperature being 210 to 280 DEG C; after the resin base powder is cured, woodgrained paper is pasted to the resin base powder; and then the aluminum honeycomb panel provided with the woodgrained paper in a pasted manner is placed into an oven for high-temperature thermal transfer at 210-260 DEG C, so that the surface of the aluminum honeycomb panel has the effect of natural wood grains, and the decoration effect the same as that of natural wood is achieved.

The invention discloses a synthesis method of a water-soluble triene cross-linking agent. The synthesis method comprises the following steps: adding triaminopropylamine (trpn), water and cationic surfactant into a reactor, evenly stirring and mixing, controlling the reaction temperature in a range of 30 to 35 DEG C, dropwise adding chloropropene into the reactor within 4 hours, controlling the temperature under 35 DEG C, and keeping on stirring until the solution turns transparent after the adding of chloropropene so as to obtain the triene cross-linking agent. The invention also provides a synthesis method of a high-temperature resistant water-absorbing resin by using the triene cross-linking agent. The synthesis method comprises the following steps: adding a mixed solution of copolymerization monomers and the triene cross-linking agent into a reactor, introducing nitrogen gas for 30 minutes, then adding an initiator, stopping introducing nitrogen gas after 10 minutes, carrying out reactions for 4 hours at a room temperature so as to obtain a reaction product, subjecting the reaction product to an extruding and granulating process, drying the granules at a temperature of 80 DEG C, and finally grinding the dried granules so as to obtain the high-temperature resistant water-absorbing resin.
