Influence of Nano-Dimensional Additives on Adhesion Ability of Protective Polymer Coatings

The technology of protective thermo-dustable polymer coatings from polyethylene of low pressure (HDPE) for anticorrosion protection of metal surfaces of treatment facilities for agricultural purposes is proposed. An important characteristic of such coatings is the value of adhesion, which ensures long-term operation of the facilities. Therefore, in the first place, the influence of nano-sized additives on the adhesion of protective coatings was studied. As a result of complex laboratory studies, it was found that to ensure the required permeability and corrosion resistance of polymer protective coatings, it is rational to introduce a special additive of nanosized compositions into their composition, which guarantees an increase in the strength of the created film by 25–45% due to the creation of a branched structure of sprayed polyethylene. This fact is confirmed by the results of physical and chemical studies. The obtained protective coatings have an improved quality against penetration of aggressive liquids and livestock environments.
