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.

Method for modification of the surface of industrial rubber articles

A process for the manufacture of industrial rubber articles comprises vulcanization of a rubber mix, wherein prior to vulcanization the rubber mix is treated with a fluoroorganic compound and after vulcanization the articles are placed into a sealed chamber with the pressure therein below 10 Pa. An electric glow discharge is ignited in the chamber and the articles are treated therewith. The treatment with the electric glow discharge is stopped when a residual pressure in the chamber of below 100 Pa is reached. The process for the manufacture of industrial rubber articles according to the present invention makes it possible to produce articles with a coefficient of friction on their surface of from 0.2 to 0.6 depending on the type of rubber and enables an increase in productivity of machines and apparatus.
