Abstract
The processes of obtaining compositions based on organosilicon resin for a heat-resistant coating of accelerated drying, as well as its hydrophobization by creating an isotropic nano-microstructure on the surface, are studied. It is shown that the chemical nature, the content of the ingredients and the thickness of the coatings have the greatest influence on the physicochemical properties of heat-resistant coatings. The methods of obtaining a composition for heat-resistant coatings using a dissolver and a bead mill in various modes of operation were studied, which allowed us to develop a technological process for manufacturing heat-resistant paint and varnish material. The composition and technology of obtaining a final hydrophobic layer based on a suspension of aerosil HDK 12H and carbon nanoparticles in a fluorine-containing varnish LF 32LN was developed in order to obtain a complex heat-resistant, superhydrophobic and anticorrosive coating for the protection of metal products and its properties were investigated.

Summary
Исследованы процессы получения композиций на основе кремнийорганической смолы для термостойкого покрытия ускоренной сушки, а также гидрофобизация его путем создания на поверхности изотропной нано- микроструктуры. Что наибольшее влияние на физико-химические свойства термостойких покрытий оказывают химическая природа, содержание ингредиентов и толщина покрытий. Исследованы способы получения композиции для термостойких покрытий с применением диссольвера и бисерной мельницы в различных режимах их работы, что позволило разработать технологический процесс изготовления термостойкого лакокрасочного материала. Разработан состав и технология получения финишного гидрофобизирующего слоя на основе суспензии аэросила НDK 12H и углеродных наночастиц во фторсодержащем лаке ЛФ 32ЛН с целью получения комплексного термостойкого, супергидрофобного и антикоррозионного покрытия для защиты металлических изделий и исследованы его свойства.
