Description

The invention relates to coating compositions containing wax-like triazines as components. Such compositions are used as protective or decorative coatings for various materials, for example inorganic, such as stone, metals, etc., organic, for example wood, leather, nlastmassy, as well as textiles and paper.

It has been established that triazine derivatives of general formula I

where Ri, R2, Rs are radicals independent of each other, representing each amino group substituted by one or two aliphatic residues, or substituted or unsubstituted saturated 3-7-membered nitrogen heterocycle, which may contain other heteroatoms attached through a ring nitrogen atom ,

a nitrogen heterocycle linked through two nitrogen atoms to both triazine rings can be used as a component of the coating composition. As aliphatic substituents of the amino group Ri, R2 or Rs, aliphatic open-ended or cycloaliphatic residues are considered. As aliphatic open chain residues may

to be applied, in particular, those which have straight or branched chains of alkyl or alkenyl residues containing from 1 to 22 carbon atoms. The open-chain aliphatic residue as a substituent for the primary amino group contains 6-22 carbon atoms, preferably 10-22, while for both open-chain residues as substituents of the secondary amino group, one is predominantly an alkyl or alkenyl residue with 1-6 atoms carbon, the other - those with 6-22 carbon atoms.

These alkyl and alkenyl residues may, in turn, contain or not

contain one or more hydroxyl groups or halogen atoms. For example, 5-7-membered cyclic systems, which, if nitrogen is present, may contain in the cycle also other heteroatoms, in particular oxygen, sulfur. Such heterocycles include cirrolidine, piperidine, piperazine, 1-alkylpinerazine, morpholine, thiomorpholine, as well as hexahydroazepines or hexahydrodiazepine. Such heterocycles can be unsubstituted or repeatedly substituted, for example, by alkyl 1) 1e or haloalkyl groups. The radicals of polybasic amines forming the bridging unit X may be radicals of aliphatic polyamines, in particular ethylene diamine, hexamethylenediamine, K, N-bis (gammaamino-yropyl) - N-methylamine, aromatic or alicyclic polyamine radicals, for example, fsylyanediamine and symphidine diamine, diamine diamine, and aromatic or alicyclic polyamide radicals, for example, fsylylenediamine, symphony diamines, and aromatic or alicyclic polyamine radicals, for example, fsylylenediamine and symphidine diamine molecules, or aromatic or alicyclic polyamine radicals, for example, fsylylenediamine and symphonic diamino groups; -aminomethylcyclohexane, heterocyclic nolamine, in particular 2,6-diaminopyridine, as well as radicals of not less than dibasic hydrogenated heterocycle containing nitrogen, for example piperazine. Triazines of general formula I are obtained by the interaction of two equivalents of 2-guanidino4-amino-5-triazine of general formula II 1Г "V, where Hal is a halogen atom with a sequence number of up to 35, RI, Ra, Kz are independent of each other, each amino group substituted by one or two aliphatic residues, or a substituted or unsubstituted saturated 3-7-membered nitrogen heterocycle, which can contain other heteroatoms and is attached via a nitrogen atom, with one equivalent of a polybasic amine or at least dibasic a clinical compound, salt; nitrogen, in the presence of an agent capable of binding acids, at temperatures of 100-300 ° C in the presence of a solvent or diluent. High-boiling organic liquids with a boiling point higher than 100 ° C, for example aliphatic and aromatic hydrocarbons such as high-boiling petroleum fractions, toluene, xylene, halogenated hydrocarbons, in particular chlorobenzene, high-boiling ethers, : M-alkylated amides of acids, sulfoxides, etc. According to the invention, they are used as inorganic bases as carbonates, alkali hydroxides and alkaline earth metals as an acid binding agent. allov, and organic bases such as tertiary amines, for example pyridine and collidine. In many cases, it is advisable to use tertiary amines, such as pyridine, as a solvent or diluent, which simultaneously perform the functions of an acid binding agent. The triazines of the formula I used according to the invention are characterized by certain melting points and are wax-like. Therefore, they can serve as substitutes for natural and synthetic waxes used in the industry or can be used with them for processing and finishing the surface of products from all materials. They have the characteristic properties of natural waxes, for example, solubility in solvents for fats and compatibility with synthetic and natural waxes. With the help of appropriate emulsifiers in water, triazine liphrmules I can be processed into thin emulsion emulsions, they form films resistant to chemical agents, in particular alkali. By their suitability of PAs used as waxes, they are practically equivalent to the ester of montanic acids (acids of moi-, tan-wax). Triaziums of the formula I. are also suitable as a mild fabric for textiles of all types. According to the invention, a coating composition is prepared by displacing a single triazine of general formula I or several triazines of this kind with conventional coating materials. Such materials are, for example, the following: natural and synthetic waxes, resins, silicones and similar components, improving the physical properties of coatings, as well as solvents, organic and organic nanofillers, such as silicates, ground synthetic resins, anionic, cationic and non-ionic dispersants, cleaning components, in particular, natural and synthetic soaps, surfactants, pigments, lightfastness enhancement ingredients, stabilizers of all types, as well as corrosion inhibitors, ferments, dyes, biocides, or substances containing them, for example, isecticides, fungicides, bactericides, etc. The coating compositions obtained according to the invention can be produced and used in the form of aerosols, solutions, emulsions, hard solids and pastes. These formulations can also be used to protect and finish (for example, as polishing waxes) surfaces of articles made of various materials, as well as for paper processing, for example in the manufacture of carbon paper. As waxy triazines, for example, the triazines listed in the table are used.
