Abstract:
      The wear-resisting self-lubrication coatings for EPDM goods were prepared by adding the PTFE aqueous dispersion，color paste and additives into organosilicone modified waterborne PU emulsion，the thickness，adhesive force and wear-resistance of the coating on the surface of EPDM vulcanized sample were studied.The test results showed that the thickness of the matte black coating with strong stickness was about 5～10 μm，and the sliding friction coefficient was under 0.4.When the addition level of the PTFE aqueous dispersion was 10 phr（the addition level of organosilicone modified waterborne PU emulsion was 100 phr），the adhesive force of the coating was met the requirements，the sliding friction coefficient was significantly decreased，the user’s demands on self-lubrication and wear-resistance could be reached.
