MODIFYING EFFECT OF PETROCHEMICAL WASTE PROCESSING PRODUCTS ON WETTING AND STABILIZATION OF SOLID-PHASE PARTICLES
Relevance. As evidenced by the experience of the world practice, for paint and varnish materials based on traditional film-forming materials, the introduction of modifying additives of various functional purposes is required to ensure optimal decorative and protective properties. The lack of own manufacturers of a wide range of modifying additives leads to the need to import them from foreign countries, which significantly increases the cost of paint and varnish products. The presence of huge petrochemical waste (on a large scale) makes it possible to produce cheap, effective and competitive modifying additives. The integration of research and production enterprises will increase the profitability of the production of paint and varnish products, as well as solve a number of issues related to the preparation, storage and improvement of the performance characteristics of paint and varnish coatings. Paint and varnish compositions are considered stable, the stabilization of pigment dispersions is carried out due to the formation of adsorption-solvate layers around the pigment particles from the film-forming macromolecules and the added surfactants. In this regard, diphilic compounds that play the role of surfactants with a stabilizing effect are of great practical interestThe main aim of the research is to study the wetting and stabilizing effect of the low-molecular-weight amino derivative AC-1, synthesized from petrochemical waste (СRP-92), in the composition of paint coatingsMethods: pipette method of sedimentation analysis of suspensions, the method of the adhered air bubble for measuring the edge angles of wetting.Result. The wetting and stabilizing effect of the amine-derived AC synthesized from petrochemical waste has been established, which makes it possible to obtain sedimentation-resistant compositions without stratification and precipitation at its dosed consumption. The effect of the film-forming agent and surfactant on stabilization of the titanium dioxide dispersion in alkyd-urethane compositions was proved.
