Abstract:
The modification of existing paints and varnishes based on alkyd resins, as well as the creation of new film formers using functionalised oligomers to improve the properties of materials in use, has been carried out.
The aim of the work is to study vegetable oils used in the production of printing inks and to modify them in order to improve their technological properties. The work carried out allows the use of printing inks based on modified vegetable oils, with the expansion of their scope of application in the production of various printed products.
The modification of vegetable oils was carried out by interaction with synthesised urethane-containing reactive block copolymers. Modification of mustard oil allows to change its structure, to increase its molecular weight by oligomerisation of the oil with obtaining of branched structure. Modified vegetable oils provide fast drying alkyd coatings, even in air.
The properties of modified oils, the rate of film formation depend on the chemical nature of the block copolymer, its reactivity. The main processes of oil film structuring are due to oxidative and thermal polymerisation of double bonds of fatty acid residues.
Optimisation of the vegetable oil modification process has been carried out, a formulation for the production of printing inks has been developed and production tests have been carried out with positive results.
Keywords: paint material, film former, modification, alkyd resin, polymerization, structuring, vegetable oil, printing ink.
