[0038] The preparation method of the above-mentioned high-temperature-resistant solid propellant for oil and gas deep wells, the method is carried out according to the following steps:
[0039] Step 1, according to the proportion of the formula, by weight percentage, the high temperature resistant epoxy resin is 10% to 20.90%, the bisphenol A epoxy resin is 0 to 16.58%, and the epoxy resin active diluent is 4.75% to 13.03%, Accelerator boron trifluoride-amine complex is 0.50%, defoamer is 0.03%, add to the mixing pot, pre-mix for 10 minutes;
[0040] Step 2: Adding 35% to 50% of potassium perchlorate and 10% to 25% of 1,1-diamino-2,2-dinitroethylene into the system of step 1 by weight percentage, and mixing for 50 minutes , then add diaminodiphenyl sulfone at 6.57% to 8.14%, and stop mixing after mixing for 15 minutes to obtain a syrup;
[0041] Step 3: pour the slurry obtained in Step 2 into a mold, put it in an oven at 130°C for 72 hours, and remove the mold to obtain a fin...
Embodiment 1
[0044] The high-temperature-resistant solid propellant for oil and gas deep wells in this embodiment is composed of the following raw materials in terms of weight percentage: 35% of potassium perchlorate, 25% of 1,1-diamino-2,2-dinitroethylene, 4, 14.40% for 4'-diaminodiphenylmethane tetraglycidylamine type epoxy resin, 5.47% for epoxy resin E-51, 13.03% for o-cresyl glycidyl ether, accelerator boron trifluoride-amine complex The compound is 0.50%, the silicone resin is 0.03%, and the diaminodiphenyl sulfone is 6.57%.
[0045] Performance Testing:
[0046] Detonation heat is determined by GJB770B-2005 method 701.2 detonation heat and combustion heat constant temperature method.
[0047]The specific volume is measured according to GJB770B-2005 method 702.1 specific volume pressure sensor method.
[0048] The test method for high temperature resistance is: Ф20mm×20mm powder column (1) 3°C / min rise to 200°C, keep warm for 48h; (2) Temperature control point: the thermocouple is ...
Embodiment 2
[0055] The high-temperature-resistant solid propellant for oil and gas deep wells of this embodiment is composed of the following raw materials in terms of weight percentage: 40% of potassium perchlorate, 20% of FOX-7, 20.90% of TGDDM, and 11.25% of o-cresyl glycidyl ether , the accelerator boron trifluoride-amine complex is 0.50%, the silicone resin is 0.03%, and the diaminodiphenyl sulfone is 7.32%.
[0056] The performance test method of the high-temperature-resistant solid propellant for oil and gas deep wells in this embodiment is the same as that in Embodiment 1, and the performance test results are shown in Table 2.
[0057] Table 2 embodiment 2 each performance test result
[0058]
[0059] It can be concluded from Table 2 that the heat of detonation (that is, energy) of the propellant is slightly higher, the specific volume is moderate, and the high temperature resistance, water resistance and salt water resistance all meet the performance requirements. Suitable f...
