[0046] The preparation method of the sealing glass material of the explosion-proof lithium battery cover group comprises the following steps:
[0047] 1), select raw materials according to the following molar percentages:
[0048] SiO 2 : 40%~60%,
[0049] B 2 o 3 : 10%~30%,
[0050] Al 2 o 3 : 0%~5%,
[0051] BaO: 5% to 15%,
[0052] Na 2 O: 5% to 10%,
[0053] K 2 O: 0% to 5%,
[0054] MgO: 0% to 5%,
[0055] CaO: 0% to 5%,
[0056] TiO 2 : 0%~5%,
[0057] ZrO 2 : 0%~5%,
[0058] ZnO: 0% to 5%,
[0059] Among them, various oxides should include various salts and acid-base compounds;
[0060] 2) Prepare the above-mentioned raw materials and place them in an ultra-high-speed disperser for mixing and dispersing, so that various raw materials can be mixed and dispersed evenly;
[0061] 3) Put the uniformly mixed materials in the crucible, place the crucible in a silicon-molybdenum furnace, and raise the temperature from room temperature to 300-600°C at a rate...
Embodiment 1
[0078] 1), a sealing glass material for explosion-proof lithium primary battery cover group, prepared from the following raw materials in terms of molar mass ratio: SiO 2 : 40%, B 2 o 3 : 30%, Al 2 o 3 : 1%, BaO: 10%, Na 2 O: 9%, K 2 O: 3%, MgO: 2%, CaO: 2%, TiO 2 : 1%, ZrO 2 : 1%, ZnO: 1%.
[0079] 2) Prepare the above-mentioned raw materials and place them in an ultra-high-speed disperser for mixing and dispersing, so that various raw materials can be mixed and dispersed evenly;
[0080] 3) Put the uniformly mixed materials in the crucible, place the crucible in a silicon-molybdenum furnace, and raise the temperature from room temperature to 300-600°C at a rate of 8-10°C / min in an air atmosphere, and at 300-600°C Keep warm for 30-60 minutes to promote the decomposition of various salts and acid-base compounds, then raise the temperature to 1500-1700°C at a rate of 8-10°C / min, and keep warm at 1500-1700°C for 1-2 hours; stir several times during the period , make the...
