Description

Technical Field

[0001] The invention belongs to the technical field of thermal batteries, and in particular relates to a device and method for preparing thermal battery ignition paper. Background Art

[0002] Thermal batteries are primary storage batteries that use molten salt as electrolyte and are activated by melting it using their own heat source. They have the advantages of short activation time, wide operating temperature range, long storage cycle, and maintenance-free, and are increasingly being used in weapon equipment systems.

[0003] When the thermal battery is working, an external electrical signal or mechanical force is used to ignite the igniter inside the battery. The fire source of the igniter is guided to the heating plate inside the battery through the ignition strip, so that the single battery reaches its working temperature, and the solid electrolyte that is non-conductive at room temperature is heated and melted to become an ionic conductor. An electrochemical reaction occurs between the positive and negative electrodes to generate electrical energy. Therefore, the ignition paper is an extremely important component of the thermal battery working system.

[0004] Commonly used ignition paper is made of zirconium powder, barium chromate and fiber by wet papermaking after adding water to make a paper-like material. At present, all operations for preparing ignition paper are manual operations. The preparation method in the document "Lu Ruisheng, Liu Xiaojiang. Thermal Battery, Beijing: National Defense Industry Press, 2005" is as follows:

[0005] 1) Dry potassium chromate and barium chloride in a high temperature furnace, and then prepare an aqueous solution of a certain concentration.

[0006] 2) Mix equal amounts of potassium chromate and barium chloride solution to produce BaCrO4 precipitate, and calculate the amount of BaCrO4 obtained.

[0007] 3) Take the Zr powder out of the water and dry it in a vacuum drying oven.

[0008] 4) Take a certain amount of ultra-fine glass fiber, add it into a beaker containing distilled water, and stir for 1 hour.

[0009] 5) Mix the dried Zr powder, the newly synthesized barium chromate, and the ultra-fine glass fiber that has been beaten into pulp according to the mass ratio, and stir with a stirrer for 1 hour to make the mixture uniform.

[0010] 6) Slowly pour the fully mixed slurry into a small papermaking machine while pumping air, and then rinse with distilled water.

[0011] 7) The prepared paper is taken out from the small paper maker and dried in a vacuum drying oven.

[0012] Among the raw materials used in ignition paper, barium chloride is a highly toxic hazardous chemical, and barium chromate is a carcinogenic hazardous chemical. When operated manually, it is necessary to weigh, dissolve, and pour according to the amount of each ignition paper used. Not only is the operation cumbersome, but it also frequently contacts the dust and solution of hazardous chemicals, which poses a great occupational health hazard.

[0013] In addition, during papermaking, the pulp is ignited by manually pouring it into the papermaking machine. The dispersion degree of the pulp in the papermaking machine is not high. The locations where the pulp is more distributed (the weight of Zr powder and BaCrO4 per unit volume is more) cause heat concentration, and the large amount of heat released during combustion can cause local short circuit failure of the thermal battery. The locations where the pulp is less distributed (the weight of Zr powder and BaCrO4 per unit volume is less) have a lower burning rate for igniting the paper, which reduces the reliability of the thermal battery activation.

[0014] Therefore, the existing ignition paper preparation technology has the disadvantages of low safety, low preparation efficiency, and low burning rate consistency.

[0015] The patent document with the announcement number CN110204957A discloses an environmentally friendly water-based ink and its preparation process, and the ink is prepared from the following raw materials by weight. Although the coating device of the patent discloses that the U-shaped slider drives the nozzle to move, the movement is a single-axis movement, and the device does not disclose the corresponding mixing structure.
