The Adhesion of Silica Reinforced Natural Rubber to Polyethylene.

摘要

The adhesion of natural rubber to polyethylene, using three samples of hydrated silica of different particle size to reinforce the rubber, has been examined. Laminates were made, without an intermediate adhesive layer, by injection or compression moulding, and the adhesion assessed, in the majority of cases, by peel tests, although some tensile and tensile-shear tests were also performed. The strength of adhesion was found to depend on the particle size of the silica and on the physical properties of the rubber samples. An influence of the magnitude of the coefficient of thermal expansion above the glass transition of the rubber samples on the adhesion strength was also noted. (Author)
