Abstract

The invention relates to a method for producing a film-forming composition based on tall oil or its mixture with rosin. The invention makes it possible to reduce the process temperature (from 240-280 to 170 ° C). This is achieved due to the fact that in the process for preparing the film-forming composition by treating tall oil or its mixture with rosin, fluff lime, zinc oxide, lead halite, pyrolusite and cobalt oxide with heating followed by the introduction of oxidized sunflower oil and organic solvent into the resulting product tall oil or its mixture with rosin is treated with pyrolusite at 130-170 ° C, and then treated successively with lime-fluff, zinc oxide, lead burning and cobalt oxide. 1 tab.

(5) METHOD FOR OBTAINING A FILM-FORMING COMPOSITION

(57) The invention relates to a process for the preparation of a film-forming composition based on tall oil or its mixture with rosin. The invention makes it possible to reduce the process temperature (from 2 40-280 to 170 ° C). This is achieved due to the fact that in the method of producing film-forming (her composition by treating tall oil or its mixture with cannabolok, lime-fluff, zinc oxide, lead halite, pyrolusite and cobalt oxide with heating, followed by the introduction of oxidized sunflower oils and organic solvents, tall oil or its mixture with rosin is treated with pyrolusite at 130–170 ° C, and then treated successively with fluff lime, zinc oxide, lead glut and cobalt oxide. l.

The invention relates to a method for producing a film-forming based on tall oil or its mixture with rosin and can be used in the paint and varnish industry in the manufacture of oil-oil drying oil and oil-resin varnish.

The purpose of the invention is to reduce the process temperature.

EXAMPLE 1. A reactor of 1 kg of crude tall oil is loaded into the reactor, heated to 105 ° C and held for 1-2 hours to dry the mass, then the temperature is raised to 130 ° C and pyrolusite is added in portions of 300 g, gradually increasing temperature up to

170 ° C. A total of about 3 kg of pyrolusite is added. After pyrolusite is added, 7 kg of construction lime (lime), 6 kg of zinc oxide, 2.5 kg of lead fiber, 1 kg of cobalt oxide are successively added in portions. The temperature in the reactor during the addition of metal oxides is maintained at 170 ° C. After stopping foaming in the reactor and obtaining a transparent mass, which is checked by pouring the sample from the reactor onto glass and examining it in transmitted light, 370 kg of sunflower oil are added to the reactor viscosity 9 min viscose

ps BS- t at 20 + 2 ° C, stirred, and after the temperature in the reactor was reduced by SO, the C-mass was pumped to a mixer, where it was diluted with 50 kg of white spirit. The resulting drying oil is used to make colored paints,

Example2. 300 kg of crude tall oil and kg of rosin are loaded into the reactor. The contents of the reactor are heated to melt the rosin and then dehydrated at 105 ° C for 1 hour. Then the temperature of the reaction mass is raised to 130 ° C and 5 kg of pyrolusite are added at this temperature in 300 g portions. The temperature in the process of adding pyrolusite is raised to 170 ° C. At this temperature and with constant stirring, 15 kg of construction lime (lime lime), 5 kg of zinc oxide, 5 kg of lead lithium and 1 kg of cobalt oxide are added successively. Then the reaction mass is kept for 1 hour, after which 150 kg of sunflower oil with a viscosity of 7-8 minutes are added to it using a VZ-viscometer at 20 + + 2 ° C and 370 kg of white spirit. After settling, the varnish is supplied for the manufacture of paints.

(The physico-mechanical properties of coatings obtained on the basis of oil-tall drying varnish and oil-resin of a new varnish are presented in the table.

Thus, the proposed method for producing a film-forming composition allows the process temperature to be reduced from 20-280 to 170 ° C, which leads to a decrease in the energy intensity of the process while maintaining the film-forming properties of the varnish and oil-resin varnish at the same level.
