Abstract
For several industrial applications, high friction surfaces with low adhesion are essential. Here, a poly(styrene-co-butyl methacrylate) polymer latex is coated on paper to achieve a high static friction at the interface between a coating and e.g. a wood pallet. At this interface, the adhesion should be low enough for easy removal of objects placed on the coated paper. The static friction is measured with a custom designed and constructed frictometer and is investigated as a function of temperature from 25 to 55°C and the resting time. Furthermore, the static friction is investigated with varying coating thicknesses and coatings containing calcium based fillers. Results show that the static friction is increasing non-linearly with both temperature and resting time. Furthermore, an amount of 10wt% filler increases static friction. In conclusion, the static friction coefficient between coated paper and wood are up to 700% of uncoated paper depending on temperature and resting time.
