2) compound foam heavy industry die cutting of adhesive tapes processability of the invention is good, and registration, peeling force stability is good, and high temperature is high It is small that fluctuation is peeled off after deterioration with moisture, easy heavy industry stripping, noresidue.
Present invention also offers a kind of preparation method of above-mentioned compound foam heavy industry adhesive tape, comprise the following steps：
1) polyester film and the surface corona of elastic membrane are handled so that the surface corona value of polyester film and elastic membrane after processing Reach more than 48 dynes；
2) dry compressed air and monocomponent polyurethane material are mixed, are connected with coating machine gumming pump；
3) monocomponent polyurethane of air is mixed into using the coating of smooth roll rubbing method in polyester film and the interlayer of elastic membrane, is adjusted It is whole unreel, the gap of winding tension and upper and lower smooth roll makes layer of polyurethane thickness be 300~350 μm, by 80~100 DEG C of heating Foamed solidification is shaped, and obtains compound foamed cotton layer；
4) 50~60 microns of pressure-sensitive adhesive coating on the first release layer, it is pressure-sensitive to obtain first in 80~100 DEG C of 2~3min of drying Glue-line；
5) it is 0.4~0.5Mpa to adjust composite roll pressure, the first pressure-sensitive adhesive layer is compounded in the polyester film of compound foamed cotton layer Face, winding obtain semi-finished product；
6) 50~60 microns of pressure-sensitive adhesive coating on the second release layer, it is pressure-sensitive to obtain second in 80~100 DEG C of 2~3min of drying Glue-line；
7) it is 0.4~0.5Mpa to adjust composite roll pressure, the second pressure-sensitive adhesive layer is compounded in semi-finished product obtained by step 5) Elastic film surface, winding obtain finished product；
Wherein, step 1) and step 2) without sequencing, step 3) and step 4) without sequencing.
Further, winding, the tension force unreeled are 80~120N in step 3).
The beneficial effect of technique provided by the invention is：
Compound foam base material is integrally formed using three-decker in the inventive method, and monocomponent polyurethane is PET's and TPU Directly it is prepared after heating physical blowing in interlayer, it is not necessary to which conventional method is glued PET and foam or TPU with foam with glue-line Tie compound, optimize production technology, make the production of compound foam more efficient more environmentally friendly.
