A NEW COMPOSITION BASED ON OLIGOMERS USED IN THE PREPARATION OF COMPOSITES FOR VARIOUS PURPOSES

Abstract

In order to improve the physico-chemical, physico-mechanical and operational indicators of the interconnectors used in the preparation of composites of various purposes and purposes, the known oligomers (phenol-formaldehyde, resorcin-formaldehyde, amine-aldehyde and epoxide produced on an industrial scale) are used by copolycondestruction in the composition of nitrogen, chlorine, bromine, sulfur, etc. it is functionalized with organic compounds (30 names). These compounds (modifiers) were synthesized in laboratory conditions, on industrial and semi-industrial scales. The aim of the research work is to ensure that composites prepared on their basis meet both economic and environmental requirements by maximally reducing the amount of free monomers, increasing functionality, eliminating fragility, improving basic physical-mechanical and operational indicators. The compositions, probable structures, kinetic regularities and optimal parameters of copolycondestruction reactions of new composition cooligomers have been determined. For the first time in the composition of cooligomers modified with organic compounds of various functional groups Amine, amide, hydroxyl, methylol, epoxide, etc. the presence of such functional groups has led to the use of them as coordinators. Thus, as a coordinator in the preparation of coatings resistant to various aggressive environments, as an inhibitor in the corrosion protection of equipment and devices operated in various environments, as a vulcanizing agent in the preparation of adhesives used in gluing materials of various nature, as a substitute for KU-1 modifier in the rubber industry and in the vulcanization of many elastomer-based- it was used in the preparation of oligomer-based rubber mixtures, in obtaining ion exchangers, in the preparation of friction-resistant composites, in the preparation of solutions to prevent asphalt-resin-paraffin deposits formed during the operation of high-paraffin oil wells, and positive results were obtained. Currently, research work is underway to restore, at least partially, the main operational indicators of decommissioned thermoplasts by using cooligomers as modifiers during recycling.
