ELECTRICALLY CONDUCTING PAINT

摘要

The invention pertains to the production of electrically conducting paint materials based on synthetic polymer binders and can be used in various industries to produce electrically conducting film coatings with stable electrical characteristics across the entire film coating surface on largearea dielectric substrates. The preferred area of use is that of electrical heating devices and systems used for various purposes operating at temperatures of 30-120 ~C. The electrically conducting paint material contains a synthetic polymer binder, a carbon-containing filler, a solidifier and an organic solvent. The carbon-containing filler is a mixture of graphite and soot, the relative proportion of soot to graphite being 0.05-0.1. The synthetic polymer binder consists of chloro-sulphonated polyethylene with a mean molecular mass of 20,000 and a density of 1.1-1.14 g/cm3. The solidifier is an amine-type solidifier. The organic solvent consists of aromatic or chlorinated hydrocarbons. A patent is sought for the following relative proportions of the components (in wt.%): synthetic polymer binder 6-9; carboncontaining filler 0.6-11; solidifier 4.5-7; organic solvent - the rest. The preferred temperature range for the use of the film coatings based on the electrically conducting paint material for which a patent is sought is 30-120 ~C.
