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
The invention provides the processing method of relevant a kind of insulation sheet rubber, be meant a kind of processing method of roll aluminium electrolysis capacitor insulation sheet rubber especially.
Background technology
That capacitor is to use is the widest, consumption is maximum, and the electronic component of not replacing, and its output accounts for 40% of all electronic component, and is topmost capacitor classification with aluminium electrolytic capacitor wherein.
And constitute in the element of aluminium electrolytic capacitor in group, cover plate is generally adopted insulation sheet rubber and is organized structure and form, but the processing method of insulation sheet rubber is to utilize interfacial agent at present, directly that the material of rubber and two kinds of opposed polarities of phenolic resins laminated plates (phenolic paper laminated sheet) is bonding, and form goods.But under such manufacturing method thereof, many bonding workshop sections together in the whole fabrication schedule, and need extra interfacial agent.Therefore, not only cause construct on the processing procedure loaded down with trivial details, what also the storage of Zeng Jiaing was got the raw materials ready and stored expends, moreover, tacky state also is vulnerable to the interfacial agent deterioration and is affected, and make poor heat resistance, the price of insulation sheet rubber higher with undesirable elements such as life of product is short.
Summary of the invention
Main purpose of the present invention is providing a kind of processing method of roll aluminium electrolysis capacitor insulation sheet rubber, it is directly to utilize the pressing technology, will be through rubber glued membrane after the vulcanizing treatment and the pressing of phenolic resins basal plate, to simplify the manufacturing process of whole insulation sheet rubber.
Another object of the present invention is providing a kind of processing method of roll aluminium electrolysis capacitor insulation sheet rubber, and what it can increase substantially the whole production flow process is systemization, and significantly knock down price, thermal endurance and life-span.
For reaching above-mentioned purpose, the invention provides a kind of processing method of roll aluminium electrolysis capacitor insulation sheet rubber, rubber size that provides once mixing is provided for it; Rubber size is calendered to setting thickness, to form a rubber glued membrane; The rubber glued membrane is fitted in the base material that handle through drying on a surface, to form a rubberized fabric; Rubberized fabric is carried out vulcanizing treatment, subsequently and peel off this base material, with remaining rubber glued membrane through vulcanizing treatment; And a rubber glued membrane and a phenolic resin laminated plates carried out pressing, to form the insulation sheet rubber of this roll aluminium electrolysis capacitor.
Compared with prior art, the present invention has the following advantages:
The manufacturing method thereof of the application of the invention need not utilize adhesive to adhere, so the adhesive of avoiding storage and deterioration all factors that may cause, and promoted the systematization of whole production flow process, and significantly knock down price, thermal endurance and life-span.
Description of drawings
Fig. 1 is a flow chart of steps of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail:
See also Fig. 1, it is a flow chart of the present invention.As shown in the figure, at first as described in step S1, will as flat fabric, be fixed on the calender coil handling apparatus through surperficial drying treated base material; Continue, step S2 is described for another example, and rubber size that will be after kneader is mixing with roller, fully mixes as second wheel (thick wheel is with thin wheel), and also control temperature maintenance at 70～85 ℃ this moment; Step S3 is described for another example, will be through well-mixed sizing material, send into calender with conveyer belt, this moment set calender roller temperature be controlled at 75～90 ℃ between, sizing material is calendered to the rubber glued membrane of desired thickness, and utilize the adherence of rubber glued membrane itself and the base material on the coil handling apparatus to fit, to form rubberized fabric, be enough stress and the transmission of sharp calender of rubber glued membrane that are used to provide firm shaping with making of base material at this moment; Step S4 is described for another example, rubberized fabric is carried out vulcanizing treatment, to increase hardness and durable degree, divest subsequently and with base material, to obtain rubber glued membrane through vulcanizing treatment, and carry out rolling, vulcanizing treatment can be used the drum-type vulcanizing machine with 155 ℃ temperature rubberized fabric to be carried out about 10 minutes processing can to finish in this step; At last, as described in step S5, will carry out pressing through the rubber glued membrane and the phenolic resins laminated plates of vulcanizing treatment, and utilize punching press to form various required shapes again, promptly finish the whole flow process of roll aluminium electrolysis capacitor insulation sheet rubber processing method with moulding press.
Moreover the above-mentioned employed rubber size composition of the present invention can be as shown in the table:
| Nomenclature of drug | Content PHR (parts per hundreds of rubber) |
| Ethylene-propylene diene copolymer (EDPM) 2504 | 100 |
