Patent DE-2649069-A1 (DE)
Title: Adhesive tape mfr. using melt adhesives - by mixing homogenised molten polymer with co-reactants or crosslinking agents immediately prior to application
Inventor: SCHWAMEIS WERNER DIPL ING
IPC: C09J7/20
Filed: 1976-10-28
Abstract: The process comprises (1) heating one or more polymers, to 130-160 degrees C., (2) homogenising the polymer, esp. in a kneader, (3) adding the co-reactants or crosslinking agents (I) to induce copolymerisation or crosslinking and (4) applying the reaction mixt. to the carrier tape. Suitable polymers are e.g. butadiene-styrene, isoprene, natural rubber, chlorobutyl rubber and/or ethylene-propylene rubber. The polymers may be copolymerised with phenols and/or terphenols, or crosslinked with oxygen-, sulphur-, nitrogen-, urea-, urethane-, or methylene bridges between the polymer chains. (I) may be added during the homogenisation (kneading) stage or they may be metered into the outlet lead through which the homogenised polymer flows to the applicator. (I) may be added in the molten state or as a soln. or dispersion in an organic medium such as a mineral oil. (I) may be added at copolymerisation or crosslinking temp., in which case the reaction commences immediately, or they may be added at below copolymerisation or crosslinking temp., and the mixt. subsequently heated to copolymerisation or crosslinking temp. (I) may alternatively be applied to the reverse side of the tape, e.g., by printing or magnetic doctor, so that when the coated tape is reeled up the polymer is contacted with (I) to cause the copolymerisation or crosslinking reaction to occur. The process allows adhesive tapes to be made without using solvent based adhesives, which allows high rates of prodn. and reduced environmental pollution. The method of application allows copolymerised or crosslinked polymers to be used in the adhesive layer without problems of poor storage of the polymer at elevated temps. The crosslinked adhesive layers have improved cohesive fatigue strength compared with uncrosslinked polymers so that the tapes have a wider field of application than prior art tapes.
