Matched group
Existing commercially available capacitor aluminum housing coating paint.
In order to contrast effect of the present invention, it is that the thick aluminium sheets of 0.3 ~ 0.4mm carry out the process such as defat, chromaking to choose thickness, uses
Bar spreader is coated on corresponding for above-mentioned seven kinds of modes coating on aluminium sheet, toasts 75 ~ 80s, dry film under conditions of 250 DEG C
THICKNESS CONTROL is 9 ~ 11 μ, then carries out corresponding performance test, and table 1 below is corresponding correction data：
Table 1
| Resistance to deep-draw characteristic | Otch | Draw ratio | |
| Embodiment 1 | **** | *** | 3.6:1 |
| Embodiment 2 | **** | *** | 3.7:1 |
| Comparative example 1 | *** | ** | 3.0:1 |
| Comparative example 2 | *** | ** | 3.2:1 |
| Matched group | ** | ** | 2.6:1 |
Note：Each parameter index in upper table 1 is specially：
（1）Resistance to deep-draw characteristic：Wherein：* * * are represented when applying floor height ratio of elongation without breakage, without black arc, are represented without phenomenon of growing dim, * * *
Apply floor height ratio of elongation when without breakage, without black arc, capacitive bottom have slightly grow dim, * * represent apply floor height ratio of elongation when have breakage,
Black arc, capacitive bottom seriously grows dim, * has breakage when representing the low ratio of elongation of coating, and black arc, capacitive bottom seriously grow dim；
（2）Otch：After impacting into capacitor, incision coating shedding phenomenon is observed, wherein：* * represent incision without stripping
From, * * represent incision has slight obscission, * to represent incision and seriously peel off；
（3）Draw ratio：After impacting into capacitor, outer layer film quality is without maximum draw ratio during significant change.
As can be seen from the above table, capacitor coating obtained in the present invention has resistance to deep drawability well, bonds with capacitor
Better performances, expanded capacitor manufacture and design type, have good popularizing value.
