Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: method of producing heat-resistant material for protective coating involves dissolving a polymeric binder in a solevent, where the binder is in form of poly(o-hydroxyamide), which is a product of polycondensation of dichloride of isophthalic acid with 3,3'-dihydroxy-4,4'-diaminodiphenylmethane in a solvent in molar ratio of reagents ranging from 1:1:7 to 1.05:1:15, and mixing with carbon nanofibres or carbon nanoclusters, obtained through hydrolysis of methane on a Ni/MgO catalyst with length of fibres from 50 to 100 mcm and diametre from 20 to 60 nm until obtaining a homogeneous composition. ^ EFFECT: obtained finished material is heat-resistant, is highly adhesive and has protective properties when deposited on surfaces of varying chemical nature. ^ 3 cl, 5 ex Способ получения термостойкого материала для защитного покрытия заключается в растворении в растворителе полимерного связующего, в качестве которого используют поли(о-гидроксиамид) - продукт поликонденсации дихлорида изофталевой кислоты с 3,3'-дигидрокси-4,4'-диаминодифенилметаном в растворителе при мольном соотношении реагентов от 1:1:7 до 1.05:1:15 и смешивают с углеродным нановолокном или углеродными нанокластерами, полученными пиролизом метана на катализаторе Ni/MgO с длиной волокон 50-100 мкм и диаметром 20-60 нм до получения однородного состава. Полученный готовый материал обладает термостойкостью до 400°С, высокой адгезионной способностью и защитными свойствами при нанесении на поверхности различной химической природы. 2 з.п. ф-лы.
