Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, the modified New-energy capacitance device metallized film, including insulating basement membrane 10, the insulation
The front of basement membrane 10 is provided with the coat of metal, and the coat of metal includes the mixing coating combined with 10 front of insulating basement membrane
20, the surface of the mixing coating 20 is covered with aluminium coat 30.The mixing coating 20 includes multiple pros in array setting
Shape copper plates block 21, and the spacing between adjacent copper plating block 21 is equal, and the front of the insulating basement membrane 10, which is additionally provided with, plates all copper
The tin coating 22 that block 21 is completely covered.
The modified New-energy capacitance device metallized film the production method is as follows:
1), by having wax-pattern layer 50 in 10 front surface coated of insulating basement membrane, as shown in Fig. 2, reserved on the surface of wax-pattern layer 50
Have and plate block trough 51 with the copper plating one-to-one square copper of block 21, copper plating block is then made by way of electroless copper
21.Wherein, the insulating basement membrane 10 is poly- ethyl ester film, polypropylene film, polystyrene film, one in polycarbonate film
Kind.
2) wax-pattern layer 50, is removed, as shown in Figure 3；Tin coating 22 is made by way of vacuum coating, as shown in Fig. 1,4；
Tin coating chamber of the tin coating 22 in vacuum coating equipment carries out vacuum coating operation, and the gauge pressure inside the tin coating chamber is small
In or equal to -2 × 10-5Mbar, the heating temperature in tin coating chamber inside tin evaporator crucible are 825~850 DEG C, in tin coating chamber
It is -3~0 DEG C for cooling down the cooling temperature of the chill roll of insulating basement membrane.
3) aluminium coat 30, is made by way of vacuum coating and obtains finished product.The aluminium coat 30 is in vacuum coating equipment
