Adhesive for glueing rubber and plastics

摘要

An adhesive for glueing rubber and plastics, esp. polyesters, consists of an aq. dispersion of a rubber milk, a Novolak condensate of resorcinol and HCHO, and a Resol condensate of resorcinol and HCHO. The Novolak condensate is prepared by e.g. condensing 1 mole resorcinol with 0.1-0.8 mol HCHO with 1 mol resorcinol in presence of 15-550 mol H2O.
