O5 1 The invention relates to decorative art for obtaining a special effect, in particular to the manufacture of decorative enamel imitating the luster of a metal. Known decorative enamel, imitating the gloss of metal, including alkyd and melamine-formaldehyde resins, aluminum pigment, orgaiic dye and organic solvent. 1. The disadvantage of decorative enamel is its poor quality associated with both yyen / him type and weather resistance. . The purpose of the invention is to improve the quality of decorative enamel. The goal is achieved by the fact that decorative enamel, imitating metal shine, including alkyd and melamine forms of aldehyde resins, aluminum pigment, organic dye and organic solvent, also contains a transparent highly dispersed iron oxide pigment and the product of the interaction of polyethylenipolyamine and synthetic fatty acids and a polymethylamine resin and synthetic fatty acids and polymetraphenol oxide; May % .: Alkyd resin 27.7-28.3 Melami-formaldehyde resin 16.7-17.0 Aluminum pigment1,2-, 5 Organic dye 1.0-2.0 Transparent high disperse / kelezookoki pigment0.9-1.2 The product of the interaction with polyethylene polyamine is with the organic acid and others. As an alkyd resin, phthalic and adipic acid polyesters are used with myogastric alcohols (glycerin, pentaher trit, etriol) , modified NLP C mashines with n-fatty acids. Orgaic dye is used as alcohol, ak and atsetonorastvorimye. .a, .1) omi1 ievy pigment used neysplyzayuschey for.me (paste H-1, H-2). The area of the slurry is 2-6 microns, the thickness of the slurches is 0.05-0.15. um Transparent highly dispersed kelozokisis (pigment differs from the usual: iron oxide pigments that are different from the cervical particles (average particle size is 0.03 µm, versus 0.2-0.6 fKM for opaque type G-0, F -, Ж-2, К, КМ. 4). The product (adhesive additive) of the interaction of polyethylene polyamchcha (PEPA) and syngothic fatty acids (FFA) 11 is a very high-quality compound with a specific weight of 0.87-0.88, 6 fluidity temperature 55--65 ° C, acid number 8.5-30 mG KOH / H, alkalinity not less than 17 MG KOH It is not more than 75 ° C and a water content is not more than 2 ° / o. A decrease in the content of transparent finely dispersed iron oxide pigment below 0.9% leads to a sharp improvement in the quality of decorative enamel as from the standpoint of external appearance (coatings fade) and from the point of view its weather resistance (protective properties deteriorate), and an increase in its content above 1.2% leads to a decrease in the initial decorative properties. Examples of the obtained decorative enamels imitating the luster of a metal are given in Table. 1. Decorative enamel, imitating the gloss of the metal is obtained as follows (example I). Pre-prepare a solution of an organic dye (1.0 g) in alcnd (26.8 g) and melamine formaldehyde (16.1 g) resins dissolved in xylene (29.682 g) and butanol (16.1 g); then a pigment paste is prepared by loading a highly dispersed iron oxide pigment (0.9 g) into a bead mill, Interaction Product. PEPA and FFA alkyd (1.5 g) and melamine-formaldehyde (0.9 g) resins dissolved in acid (2.1 g) and butanol (0.9 g) and dispersed for 3 hours at room temperature; an aluminum pigment slurry is then prepared, loading it into the mixer (1.2 g) together with xylene (2.2 g) and transferring to normal conditions under normal conditions. Then, the resulting dye solution (89.682 May. H), suspension of aluminum pigment (4.0 May. H.), Pigment paste (6.318 May. H) are loaded into the mixer and mixed under normal conditions until a homogeneous state. The composition in its normal form has a viscosity of 50-90 seconds with a VZ-4 viscometer at 20 ° C and before use it is diluted to a working viscosity of 18-22 seconds with a VZ-4 meter of xylene, butyl acetate or their mixture. In order to obtain a coating, decorative enamel is applied by pneumatic or electrostatic spraying on a previously primed metal or glass surface in 2 layers wet on wet with intermediate substance at 18-22 ° C for 3-5 minutes. Curing of the coatings takes place at 130 ° C for 30 minutes. The thickness of the two-layer coating is 35-40 microns. The comparable properties of decorative enamels that mimic the gloss of metal and coatings based on them are given in Table. 2
