Novel rubber steelcord adhesion technology


It is the objective of this project to develop a new
adhesion system for steel cord reinforced rubber goods
such as tyres, conveyor belts or hoses.
Today's technology in this field is based on the
formation of sulphide layers tightly interlocking with
rubber. The sensitivity of these sulphide layers to
severe service life conditions represents a major
limiting factor for optimum endurance properties. The
proposed approach will utilise a class of bifunctional
organic molecules which have shown to form strong
covalent bonds between metallic substrates and polymers.
Non destructive and in situ spectroscopic methods will be
developed for a complete understanding and control of the
applied measures. Thus the reactivity of the coated
molecules can be tailored to match different metallic
surface conditions.
By significantly improving both endurance and corrosion
resistance, key factors of growing importance for the
retreadability of truck/bus tyres, the project addresses
the competitiveness of the industrial partners.
Since the new technology will benefit from and depend on
the excellent technical infrastructure within the EU it
represents an effective way of competing against low cost
products and production sites. An exploitation phase can
be envisaged after truck tire fleet test 3 4 years after
project end.
