METHOD FOR PRODUCING WATERPROOF CARBON-CONTAINING COATING FOR DETAILS FROM CHEMICALLY ACTIVE MATERIAL Russian patent published in 2017 - IPC B05D1/24 B05D7/24 C09D123/06 C08K3/04 C08K5/13 C08K5/18 

FIELD: chemistry.

SUBSTANCE: method involves preparing the powdered polymer material to produce a predetermined dispersion fraction, applying the polymeric material to the heated part in a vibro-vortex method. Before applying the polymer coating, the coated part is fixed on a support, then heated, a "fluidized bed" is formed from the particles of the starting polymer material, which is a composition from a mixture of high-pressure polyethylene with a dispersion of not more than 315 mcm, technical carbon and heat stabiliser from among the derivatives of aromatic phenols or secondary aromatic amines, with the following ratio of ingredients, wt %: technical carbon - 1.5-2, thermal stabiliser - not more than 2, high-pressure polyethylene - the rest. The heating of the part is carried out under certain conditions and the thickness of the coating is controlled, varying the multiplicity of immersion of the articles to be coated in the mass of the "fluidized bed" of weighted particles and the time that the products are in the said medium until the specified coating thickness is reached.

EFFECT: ensuring the possibility of producing a reliable waterproof coating on chemically active materials, increasing the resistance to embrittlement of the coating at operating temperatures of parts close to the temperature of destruction of the polymer coating, simplifying the method.
