FIELD: construction industry.
SUBSTANCE: invention refers to corrosion-resistant filler on the basis of lignified wastes of plant raw material, which is included in lacquer coatings and used for protection of metal surfaces against corrosion. Filler includes base made from lignified wastes of plant raw material crushed till powder is obtained, and amine-bearing addition. As lignified wastes of plant raw material, there used are fruit kernels (apricots, peaches, cherries, plums) and/or shells of nuts (walnuts, almond nuts, pistaches, coconuts, pine nuts, peanuts) or their composition with kernels of berries (grape, pomegranate, cornel), which are crushed to 5-40 mcm particle size. As amine-bearing addition, there used is monoethanolamine or triethanolamine.
EFFECT: filler has high corrosion-resisting properties and properties of rust solvent.
