Definitions
- the conductive contacting adhesives described above generally contain as electrically conductive filler metal particles z. Based on silver, copper or nickel such as Master Bond EP76M, Delo Dualbond IC 343 from Delo Industrial Adhesives, Loctite 3880 from Henkel. Such adhesives are usually cured by cross-linking.
- liquid or pasty systems such as PVC plastisols or polymers dissolved in solvents are used as the electrically conductive, curable polymeric paste or thermoplastics in the molten state.
- a further advantage of intimate impregnation in the manner according to the invention is a simultaneous and additional protection of the electrically conductive electrodes against aging effects such as heat aging and aging in a hot, moist environment. It is also advantageous that the viscosity of the paste, if this is an aqueous polymer dispersion, in contrast to other commercial Kunststofftechniksklebern by the addition of water or commercial thickeners for aqueous dispersions in a wide range can be set almost arbitrarily without the positive properties of electrically conductive paste are adversely affected.
- the conductive paste (adhesive) was then thermally cured in an oven at 80 ° C.
- Table 1 Application properties of conductive adhesives unsupported After hydrolysis storage (7 days at 70 ° C and 95-100% humidity) After 200 h heat storage (at 120 ° C) Viscosity [mPas] Adhesive curing temperature [° C] Heating the contact bands at 6 V Temperature of the resistance heating after 10 min 6 volts Heating the contact bands at 6 V Heating the contact bands at 6 V Reference recipe 1 > 200000 80 (4 minutes) significant warming 46 ° C significant warming significant warming and hotspots Reference recipe 2 30000 80 (30 min) 100 (10 min) no warming 46 ° C no warming no warming Reference recipe 3 50000 - 150000 125 (10 min) 175 (3 min) no warming 47 ° C no warming no warming example recipe 1000 - 10000 80 (4 minutes) no warming 48 ° C no warming no warming no warming
- Table 2 Contact between electrode tape and electrically conductive surface (visual assessment) according to De Mattia test (DIN 53522) 10000 cycles Electrode condition at the clamping Electrode condition at the kink site Reference recipe 1 Breakage of all strands Strands partially broken Reference recipe 2 Breakage of all strands Strands partially broken Reference recipe 3 Breakage of all strands Strands partially broken Inventive sample formulation Strands undamaged Strands undamaged
- the electrode bands of the Fig. 3 are glued with the inventive electrically conductive paste only so that they are only partially enclosed by this and otherwise rest only on the conductive paste.
