られた．[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for fixing an element of an electrolytic capacitor, and more specifically, an element fixing structure for an electrolytic capacitor that provides an electrolytic capacitor having flame retardant properties. Regarding the body. [Prior Art] An aluminum electrolytic capacitor is manufactured by impregnating an element made by winding an anode foil and a cathode foil with an oxide film dielectric on the surface in a predetermined electrolyte solution, and then sealing the element in a case. However, in order to securely fix the element and the gate, a fixing agent is often interposed between the element and the case. A typical electrolytic capacitor is about a few centimeters in size, and the element that is fixed inside the case can be fixed with a small amount of force. Therefore, the properties that a fixative should have are:
Ease of handling is more important than the amount of fixing force. From this point of view, it is considered that a fixative having properties similar to an organic plastic substance is suitable. As a fixing agent for aluminum electrolytic capacitors, -fi
Pitch or atactic polypropylene is used for this purpose. Among these, pitch is a black carbonaceous solid residue produced during the distillation of tar obtained by carbonization of organic substances. This substance is relatively easy to handle, its fixing force is sufficient to fix the element and case, and since it is a residue, it is inexpensive. Although atactic polypropylene is more expensive than pitch, it can be used satisfactorily as a fixing agent for electrolytic capacitors. Therefore, even if pitch or atactic polypropylene is used as a fixative, under normal conditions the g
! There are no particular problems with delivery or use. However, if a short circuit occurs for some reason while using a capacitor, a spark may ignite the element, spread to the fixing agent, and increase the intensity of the fire. Substances such as pitch and atactic polypropylene melt at high temperatures around 200°C, which can be expected in the case of aluminum electrolytic capacitors, and become oil-like, making them easily combust when exposed to flames. [Problem M to be solved by the invention] The present invention provides an element fixing structure for an electrolytic capacitor that is difficult to burn and a flame-retardant electrolytic capacitor by using a unique compound as a fixing agent for an aluminum electrolytic capacitor. The purpose is to [Means for Solving the Problems] According to the present invention, there is provided a structure for fixing an element of an electrolytic capacitor, which is interposed between an element housed in an aluminum gate of an aluminum electrolytic capacitor and an aluminum case. An electrolytic capacitor characterized in that the fixing agent for fixing the element and the aluminum cous is made of a silane compound.Suitable electrolytic capacitor element fixing #I body if the silane compound is a silane compound having a reduced table structure of the following formula. If the fixative is designated as silicone gel or silicone rubber, the flammability of the fixative can be minimized, and even if the device ignites, the silane compound will not be present. Advantages such as the fact that the fixing agent is not burned out and no damage is caused can be more effectively exhibited, and a suitable element fixing structure for electrolytic capacitors can be obtained. If the silane compound is a silane compound having an addition type structure of the following formula, a suitable element fixing structure for an electrolytic capacitor can be provided: It is prepared by mixing two liquids with a chemical compound, and as the reaction progresses, it solidifies into a gel-like or rubber-like state while generating hydrogen gas. On the other hand, apart from the addition type, there is a group of condensed type silane compounds, and there are various types depending on the condensation product, such as acetic acid type, oxime type, alcohol type, amide type, and acetone type. All of these give condensation products through condensation reactions, and gel-like or rubber-like products with a certain structure are obtained. In the case of a condensed silane compound, a condensation product is produced by a predetermined reaction mechanism, but the basic structure of the St rubber remains unchanged. Because the reaction rate varies depending on the reaction, the curing rate may differ,
Depending on the type of product, the presence or absence of odor and the adhesiveness of the rubber itself change. In the present invention, it is preferable to use the alcohol type, which provides alcohol as a condensation product, among the types described above. FIG. 1 schematically shows one embodiment of an electrolytic capacitor equipped with an electrolytic capacitor element fixing structure according to the present invention. Furthermore, the structure of the silane compound used in the present invention is shown in FIGS. 2A and 2B, and the structure of conventional atactic polypropylene is shown in FIG. 3. [Function] Even if pitch or atactic polypropylene is used as a fixing agent, there is no particular problem in manufacturing or using electrolytic capacitors under normal conditions. At high temperatures around 200°C, it melts into an oily state, and has the property of easily combusting when brought close to fire, so there is always the possibility of serious injury. On the other hand, when a silane compound is used as a fixing agent, even if the element catches fire, the silane compound fixing agent will not burn out and will not mix with the above two substances and cause any serious problems. Furthermore, it has been confirmed that the silane compound of the present invention burns in high-temperature conditions, but immediately chars to a white color, preventing the momentum of fire and having excellent fire resistance, and imparts more effective flame retardant properties to electrolytic capacitors. [Effects of the Invention] According to the present invention, by using a silane compound as a fixing agent for an aluminum electrolytic capacitor, it is possible to obtain an element fixing structure for an electrolytic capacitor that is difficult to burn and a flame-retardant electrolytic capacitor. be able to. [Mitsukata #! Examples ] The present invention will be explained in more detail with reference to Examples below, but the present invention is not limited only to the Examples below.衷鳳 1 As shown in Figure 4, 10 g of a silane compound, pitch, and atactic polypropylene that can be used as fixatives were placed in an aluminum case and heated to 20 G'C.Next, flame was brought close to the combustion state II. In another experiment, we used addition-type and reduction-type silane compounds, cured these two types of silicone rubber in an aluminum case, and then heated the aluminum case to 200°C. ．Next, I brought the flame closer and detected the state of combustion.
It remains solid even when heated to around 250℃, and when brought near a fire, it partially ignites in about 20 seconds, but extinguishes itself after 30 seconds.
The burnt part changes from transparent and elastic to white and solidified. In another experiment, when addition-type and reduction-type silane compounds were used as described above, they remained solid even at around 200°C. Even when the temperature was increased, the initial state remained exactly the same. When exposed to fire, it does not burn at all,
There was no burning or charring on the surface. The clay becomes liquid at around 200 degrees Celsius, and when brought close to a fire, it becomes about 5
It ignites in ~6 seconds, and the fire spreads over the surface of the aluminum case, burning with flickering flames. Attachment: Propylene becomes liquid at around 200°C, and when brought close to fire, it turns out to be about 1
It ignites in 0 seconds, spreads to the aluminum surface, and burns with flickering flames. Etched foil of 37x 1800+in+ was chemically converted in boric acid solution at 300V. This anode foil and negative foil were wound to form an element. The rating was 200V, 580μF, and the size was 30φ x 50J. This element was impregnated with a specified electrolyte for driving an aluminum electrolytic capacitor. This element was encapsulated in an aluminum case using a fixing agent consisting of a silane compound, pitch, and atactic polypropylene (trade name: VISTAC). Thereafter, as shown in Figure 5, this element was directly heated to around 200°C, and the combustion state was observed by bringing a flame close to it. The results are shown below. In another experiment, we conducted an experiment using addition-type and reduction-type silane compounds. Etched foil of 37X 18001 was chemically converted at 300 V in a boric acid solution. This anode foil and cathode foil were wound to form an element. Rating is 20
0V, 560μF1 size was 30φ x 50J, and this element was impregnated with a specified electrolyte for driving an aluminum electrolytic capacitor. This element was encapsulated in an aluminum case using a fixing agent consisting of addition-type and condensation-type silane compounds, pitch, and atactic polypropylene (trade name: BISTACK). Then, as shown in Figure 5, this element is directly heated to around 200 degrees Celsius, and a flame is brought close to it to create a combustion state! l! I guessed it. Since ZiZ is a thermosetting material, it did not melt even at temperatures around 200°C. When I brought the flame close to it, smoke appeared in about 15 seconds, and flames were visible in about 25 seconds. The strength of the flame was the weakest. When the element was dismantled after self-extinguishing, the surface of the fixative was burnt and scorched white, but the layer underneath was transparent.Furthermore, there was evidence that the electrolyte in the element had burned, but the silane compound was not present. , only the surface part was charred white. In another experiment, when addition-type and reduction-type silane compounds were used as described above, they did not melt even at around 200°C. When the flame was brought close, smoke was visible after about 10 seconds, and flames were observed after another 10 seconds. The strength of the flame was the weakest. After self-extinguishing, we checked the fixative and found no signs of scorching or combustion. In addition, evidence of combustion of the electrolyte in the element was observed. Pitch begins to melt at around 200℃. When I brought the flame close, I could see flames in about 15 seconds. The flame intensity was the most intense among the three fixatives. When the element was disassembled after self-extinguishing, traces of the electrolyte and pitch burning together remained. Attack Polypropylene Vistak Vistak begins to melt at around 200°C. When I brought the flame close,
Smoke appeared in 10 seconds, and flames could be seen in about 20 seconds. The flames weren't as strong as the pitch, though. It was stronger than silane compounds. When the element was disassembled after self-extinguishing, there was evidence that Vistaq had flowed into the element, and further evidence that the electrolyte and Vistaq had been burned together in the element was also observed.
