Adhesion propertie sof blends of incompatible elastomers communication 1. Influence of the order of introduction of the filler into a blend of incompatible rubbers on the separation resistance of adhesively bonded joints

摘要

The state of the surface layer of a polymer adhesive or substrate, consisting of two or more components (filler, plasticiser, polymer of a different nature, etc.), is of great theoretial and practical interest. A few studies (ref. 1, p.268; ref. 2) have shown that the ratio of polymer phases in the surface layer of a blend is influenced considerably not only by the nature of the blended polymers and their ratio and viscosity (refs. 3-5) but also by the order of introduction of the ingredients (ref. 6). The nature, concentration, and order of mixing of the main components of the rubber mix affect the ratio of components in the surface layer of the blend of incompatible rubbers.
