Description
Technical field
The present invention relates to a kind of Pressuresensitive Tape that can be used for insulation, coiling and the protection use of lithium ion battery manufacturing processed; specifically; described Pressuresensitive Tape has base material and glue-line; also has in case of necessity printed layers; described glue-line can contain pigment; and in coloured Pressuresensitive Tape, Cl, Br content all are no more than 900ppm, and Cl, Br content sum are no more than 1500ppm.
Background technology
Now, halogen compounds still has in various plastics additives widely and uses, the effect that although halogen has is fire-retardant, improve burning-point, but halogen-containing material can produce a large amount of toxic gases (as Dioxins when burning, furans), welding, and can exist for many years in environment, accumulate on even all the life organism.Therefore, a plurality of countries in the world all actively promote non-halogen motion with organizing, the EIC61249-2-21 standard of announcing in 2003 has proposed Halogen-free requirement to plastic material, and namely in plastics, the content of chlorine, bromine must not distinguish over 900ppm, and sum must not surpass 1500ppm.
On the other hand, in lithium ion battery is made the course of processing, be to play the end end termination of battery pole ear, the insulation protection of pole plate, the effects such as reinforcement of battery case, extensively used as the adhesive tape of protecting materials.For example; the pressure-sensitive adhesive tape that is used for preventing internal short-circuit of battery is disclosed in patent documentation 1; this moment adhesive tape whether to be attached to exactly the desired position be very important problem, for this reason tape sticker is complete after, usually can confirm its sticking position by visual or photographic camera etc.If use transparent adhesive tape, be difficult to confirm adhesive tape itself and position thereof by visual or photographic camera, this can cause neglects one's supervisory duties or the problem of mal-operation, thereby causes the interruption of production line frequently.
Disclose in patent documentation 2 and utilized pressure sensitive adhesive to form the zone of different mist degrees on the base material of adhesive tape, with the technology of the position of confirming Pressuresensitive Tape.Yet this mode still can not be identified adhesive tape itself and position thereof rapidly and accurately, does not occur so far in the art identifying rapidly and accurately adhesive tape itself and position and the Pressuresensitive Tape few to the pollution of environment.
