Chromium plating again is carved after version copper facing.
Band protecting film 4 one-faced tapes obtained by above three embodiment carries out extension test, anti-flammability is tested and old
Change and test:
As seen from the above table, the anti-flammability of embodiment 1 is less than embodiment 2 product, this is because embodiment 2 product adds
Flame retardant amount increases；The elongation at break of embodiment 1 is less than embodiment 2 product, is because in embodiment 1 base film layer thickness relatively
Thin；In burn-in test, the ageing-resistant performance of embodiment 2 product is the most excellent, and on the one hand a large amount of of fire retardant exist absorbable one
Dividing heat, in printing layer 2, high temperature defoamer also can ensure the stability of product；On the other hand, base membrane layer 1 selection and thickness design
More resistant to aging, and part improves elongation at break；And can be seen that the tensile property of commercially available one side glue, fire-retardant by upper table
Performance and ageing-resistant performance are all weaker than properties of product disclosed in this invention.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed
Use.It can be applied to various applicable the field of the invention completely.For those skilled in the art, can be easily
Realize other amendment.Therefore, under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
