ABSTRACT:
A method for modification of the surface of industrial rubber articles involving treatment of these articles with ionizing radiation in the form of an electric glow discharge and applying a polymer layer onto their surface by admitting into a chamber vapors of esters of methacrylic acid or acrylic acid, and fluorinated alcohol simultaneously with the rubber articles being treated in the electric glow discharge. This method of modifying of the surface of industrial rubber goods makes it possible to reduce the coefficient of friction of articles made by the aforesaid method, from 2 to 10 times depending on the nature of the rubber, increase productivity of machines and apparatus, and prolong the service life of packing assemblies of automobile units.
