METHOD OF OBTAINING BASE FOR COMPOSITE ANTICORROSION COATING MATERIAL AND METHOD OF OBTAINING COMPOSITE ANTICORROSION COATING MATERIAL USING SAID BASE Russian patent published in 2010 - IPC C08H6/00 C09D197/02 C09D5/08 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry and specifically to obtaining composite anticorrosion coating materials meant for protecting rusty metal surfaces from corrosion, applied directly onto the rusty metal surface, and obtaining a base - sorption materials from products of processing natural organic compounds of plant origin. The method of obtaining a base for composite anticorrosion coating material involves using cut high density wood as raw material which undergoes hydrolysis with 0.5-0.8% sulphuric acid solution, washing and pressing the hydrolysate, its ammonolysis which is carried out with a mixture containing ammounium hydroxide, sodium citrate, sodium hydroxide, citric acid sodium, water, repeated washing and pressing the ammoniated product, separation into fractions, drying the product to 5-15% moisture content. The product is activated in the presence of ammonium hydroxide, amine additives, catalyst and water, followed by grinding and activation with a composition containing ammonium hydroxide, amine additives, catalysts and water at normal pressure and temperature of 100-150°C until achieving 5-15% moisture content of the product and particle size of 1-10 mcm. The method of obtaining composite anticorrosion coating material involves preparation of a mixture of binding substance and a base for composite anticorrosion coating material, mechanical activation and dispersion of the composition with filler pigments, treatment in the chamber of an apparatus with a vortex layer of ferromagnetic particles, colouring and dilution with diluents-solvents. The material is taken for bottling and packaging.

EFFECT: method enables to shorten the time for obtaining the material and power consumption, while obtaining high-quality anticorrosion coating complex material.
