preparation example Construction
[0030] Such as figure 1 Shown, a kind of preparation method of the bonding system that the present invention discloses improves the safety performance of press-packed PBX explosives, comprises the following steps:
[0031] S1, respectively weigh chlorinated rubber, chlorinated paraffin and inert ester plasticizer according to the following mass percentage formula;
[0032] Chlorinated rubber 20%~40%
[0033] Chlorinated paraffin 30%~60%
[0034] Inert ester plasticizer 0% to 30%;
[0035] S2, adding chlorinated rubber into the reaction equipment, dissolving it with ethyl acetate to form a chlorinated rubber solution, the mass ratio of chlorinated rubber to ethyl acetate is 1:5-1:10; the reaction equipment is equipment that can be heated;
[0036] S3, adding chlorinated paraffin and inert ester plasticizer into the chlorinated rubber solution, and stirring at 50-70° C. for 10-30 minutes to obtain a bonding system.
Embodiment 1
[0038] Take by weighing 40g chlorinated rubber, 25g chlorinated paraffin-42 and 35g chlorinated paraffin-52 respectively; Add chlorinated rubber in the reaction equipment, dissolve with ethyl acetate to form chlorinated rubber solution, the mixture of chlorinated rubber and ethyl acetate The mass ratio is 1:10; chlorinated paraffin and inert ester plasticizer are added to the chlorinated rubber solution, and stirred at 70°C for 30 minutes to obtain a bonding system.
[0039] The prepared bonding system contains 40% of chlorinated rubber and 60% of chlorinated paraffin.
Embodiment 2
[0041] Take by weighing 20g chlorinated rubber, 50g chlorinated paraffin-70 and 30g DOS respectively; Add chlorinated rubber in the reaction equipment, dissolve with ethyl acetate to form chlorinated rubber solution, the mass ratio of chlorinated rubber and ethyl acetate is 1 : 5; chlorinated paraffin and inert ester plasticizer were added to the chlorinated rubber solution, and stirred for 10 min at 50° C. to obtain a bonding system.
[0042] The prepared adhesive system contains 20% of chlorinated rubber, 50% of chlorinated paraffin and 30% of inert ester plasticizer.
