Problems solved by technology

Therefore, it not only causes cumbersome construction in the manufacturing process, but also increases the cost of warehouse preparation and storage. Moreover, the adhesion state is also easily affected by the deterioration of the surfactant, which makes the heat resistance of the insulating rubber sheet poor and the price is low. High and short product life and other adverse factors

Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0011] see figure 1 , which is a flowchart of the present invention. As shown in the figure, first, as described in step S1, the base material that has undergone surface water-repellent treatment, such as flat woven fabric, is fixed on the rolling device of the calender; The rubber compound after refining is fully mixed with rollers, such as two rollers (coarse wheel and fine wheel), and at this time, the temperature is controlled to maintain at 70-85°C; as described in step S3, the fully mixed rubber compound, Send it into the calender with the conveyor belt. At this time, set the roller temperature of the calender to be controlled between 75 and 90°C to roll the rubber material to the rubber film of the required thickness, and use the adhesiveness of the rubber film itself and the The base material on the roll feeding devi...

Abstract

The invention discloses a processing method of a rolling aluminum electrolytic capacitor insulation rubber sheet. Rubber compound is pressed to a preset thickness to format a rubber film which is pasted on a substrate later. Water poking treatment is implemented on the substrate. After the vulcanization treatment, the substrate is divested. Then, the pressing mechanism technology is utilized for pressing the substrate with a phenolic resin base plate to format the rolling aluminum electrolytic capacitor insulation rubber sheet. Finally, the rubber sheet is punched according to a required shape to produce an aluminum electrolytic capacitor cover plate of proper shape.

Description

technical field [0001] The invention provides a processing method for insulating rubber sheets, in particular to a processing method for insulating rubber sheets for roll-type aluminum electrolytic capacitors. Background technique [0002] Capacitors are the most widely used and irreplaceable electronic components, and their output accounts for about 40% of all electronic components, among which aluminum electrolytic capacitors are the most important capacitor category. [0003] In the components that make up the aluminum electrolytic capacitor, the cover plate is generally made of insulating rubber sheet, but the current processing method of the insulating rubber sheet is to use a surfactant to directly combine rubber and phenolic resin laminate (phenolic paper) laminated sheet) Two materials of different polarity are bonded to form a product. However, under such a process method, there is an additional bonding section in the entire manufacturing process, and additional su...
