there-necked flask put into by poly glycol monomethyl ether and the toluene of getting 0.03mol, under the protection of nitrogen, be heated to 100-110 DEG C, adds enough sodium Metal 99.5 reaction 10-12h, until solution becomes Vandyke brown, be sodium alkoxide solution storage for subsequent use after toluene band water;
get step
the intermediate 2-fat amido-4 of middle preparation; 6-bis-chloro-1; 3; 5-s-triazine 0.015mol, joins in the alcohol sodium solution prepared, under nitrogen protection; be warming up to 40-50 DEG C to react; suction filtration after reaction bonded, the filtrate of gained is revolved and is steamed removing toluene, and under room temperature, namely seasoning obtains containing triazine ring nonionogenic tenside.
5. cohere the preparation technology of type powdery emulsifying explosive according to the superpolymer in claim 1-4 described in any one claim, it is characterized in that, comprise following concrete steps:
A: the preparation of composition B, specifically comprises:
accurately take primary oxidant and water, put into the aqueous phase dissolved tank with interlayer and whipping appts, Heating temperature is 80-90 DEG C, stirring velocity controls at 100-200r/min, make primary oxidant completely water-soluble, ie in solution is clear shape, leaves standstill 10-20min at 80-85 DEG C of constant temperature, and also device filtration is stand-by after filtration for obtained aqueous phase solution;
accurately take reductive agent and emulsifying agent, put into another oil phase melting pot with interlayer and whipping appts, be heated to 85-100 DEG C, stirring velocity controls at 150-200r/min, and insulation 8-11min obtains oil phase liquid and device filters stand-by after filtration;
regulate the whipping appts in aqueous phase dissolved tank, control stirring velocity is 150-180r/min, then by step
in the oil phase liquid for preparing slowly mode at the uniform velocity join and be shaped with in the aqueous phase dissolved tank of aqueous phase solution, the stirring velocity adding rear adjustment whipping appts is 300-380r/min, stirs 10-13min, obtains emulsion matrix;
by step
in the emulsion matrix that obtains be cooled to 45-55 DEG C, just emulsion matrix is delivered in sensitizing machine, then sensitizing agent is added sensitization in sensitizing machine, sensitizing temperature is 70-80 DEG C, sensitization 30-60s, add thickening material, density adjuster, crystalline form properties-correcting agent and stablizer in sensitizing, and be uniformly mixed and be cooled to room temperature;
B: composition A and composition B is joined in dissolving vessel, heating in water bath also fully stirs, and keeps 60-65 DEG C of constant temperature; Insulation 30-40min;
C: Heating temperature is to 70-110 DEG C, and stirring velocity is set as 500-600r/min, stirs 3-5min, continues to keep 800-850r/min, stir 5-8min, to ensure uniformly emulsify after two-phase mixes completely;
D: the mixture in step c is dried to powder under 0.005-0.025MPa negative pressure.
