Background technology
In the prior art, UV adhesive tapes used in China all are from Japan, and its structure mainly includes PVC film, UV glue
Layer, the release diaphragms of PET, release diaphragm is torn stick in wafer rear when in use, after machining, via ultraviolet
Line is irradiated from PVC directions, and the adhesion of UV glue-lines is rapidly reduced near zero in its adhesive tape, is picked up in order to choose.
At present the UV glue-line present situations employed in most domestic product be mainly reflected in it is following some:
1) it is domestic inappropriate using acrylic resin, so that poor effect, adhesive force, cohesive force deficiency are sticked together, Workflow's crystalline substance,
Easy cull;
2) domestic more unsaturated-resins using 3 carbon-to-carbon double bonds, adhesive tape drop are glutinous poor;Irradiate ultraviolet after adhesion about
50g/20mm, it can not pick completely.
3) the domestic isocyanate crosslinking for using trifunctional base mostly in addition, this crosslinking agent with after reactive acrylic resin
