COMPOSITION FOR ANTICORROSION COATING Russian patent published in 1998 - IPC

FIELD: chemical industry. SUBSTANCE: present invention describes compositions for anticorrosion coatings which include copolymer based on stillage residues resulting from styrene rectification and are intended preferably for protection of metallic, including steel, structures which are used at metal surface temperatures up to 150 C. The claimed composition comprises, wt. -%: copolymer based on stillage residues resulting from styrene rectification, 8-11; polyvinyl chloride, 11-13; cyclohexanone, 27-29; polystyrene, 4-6; antimony sesquioxide, 4-6; filler, 8-10; pigment, 5-7; and xylene, the balance. At comparatively low cost of coatings, at least by 1.5 times less then that for coatings used at present for the same purpose and having the same properties, the claimed coating retains invariable external appearance and protective properties for prolonged period of time, since composition components afford barrier and adhesion mechanism of protective effect of the claimed coating in the presence of temperature stabilizer. EFFECT: improved properties of the composition. 3 tbl
