RESEARCH OF TECHNICAL PROPERTIES OF SILICON CONTAINING ANTIPYRENS FOR PRACTICAL APPLICATION IN THE PRODUCTION OF WATER-DISPERSION COATINGS

Abstract

In the modern world, widely used water-borne paints and varnishes form coatings with high resistance to the action of water and chemicals, good electrical insulation, physico-mechanical and decorative properties. Everyone knows they are used for painting radio and electrical products, in the automotive industry, agricultural machinery, in the production of household products and residential buildings.The article discusses the technical justification of research results for the practical use of silicon-containing flame retardants in the production technology of fire-retardant water-dispersion paint. The regulations and an effective technological scheme for the production of AP-1 silicon-containing oligomeric flame retardant and the technology for producing fire-retardant water-dispersion paint coating have been developed.The test method for modified fire-retardant water-dispersion coatings based on polyacrylic dispersion was carried out according to standard methods "Determination of the combustibility of fire retardants for wood" in accordance with GOST 16363-98, which includes methods for determining the combustibility, flammability of coatings, obtained in collaboration with Laboratory Institute of Fire Safety of the Ministry of Emergencies of the Republic of Uzbekistan.Based on the data presented, based on the results of studies on the modification of the properties of fire-retardant water-dispersion coatings with silicon-containing oligomeric flame retardants, new fire-resistant water-dispersion coatings with high physicomechanical, heat-resistant, and operational properties have been developed.The developed technological regulations and the condition for obtaining coatings by the modified proposed flame retardants proposed by the authors apply to the production of fire-retardant water-dispersion paints, which are a suspension of pigments and fillers in an aqueous dispersion of synthetic polymers with the addition of AP-4 flame retardant and various auxiliary substances according to TU 6.12-78- 2000 , TU 6.12-28-96, produced by mixing components in mixers and dispersing pastes in bead mills.
