(57) Abstract:Field of application: woodworking, in particular in terms of pressure impregnation of the product and can be used for canning (antiseptic) railway sleepers, electric and Telegraph poles, ship masts, etc., the Composition includes antiseptic - coal-oil - and solvent - waste electrical oil-based chlorinated diphenylol "sovol" or "sovtol" - in the ratio of respectively 80 - 99 1 - 20 wt.%. The depth of impregnation of wood on the core is 6 mm, the sapwood - through. Antiseptic properties - sufficient. table 1. The invention relates to wood processing, in particular in conditions of autoclave impregnation products, and can be used for canning (antiseptic) railway sleepers, electric and Telegraph poles, ship masts, etc.Known composition for protecting wood, including light coal oil 50 to 95 wt. and the resin electrostatic precipitators 5 50% 
Closest to the present invention is a composition for the impregnation of wood, including antiseptic coal oil and a diluent, which use the C, in the following ratio of components, about. antiseptic 50 99; diluent 1 50 
The disadvantage of the above composition is a high water content, related to the fact that coal oil and put him in the diluent have a density comparable to the density of water, so the separation of the composition with water at normal conditions will not occur. In addition, this composition has a relatively low flash point (130-135oC), which leads to an increased fire hazard production.The task of the invention to provide a composition for impregnation of wood with a higher flash point, lower the water content of the composition, and the disposal of toxic waste.For task composition for protecting wood containing antiseptic coal oil and diluent, according to the invention, as a diluent contains waste electrical oil-based chlorinated biphenyls (sovol, sovtol) in the following ratio, wt. antiseptic 80 99; diluent 1 20.Chlorinated biphenyls (HDF) the mixture obtained by the action of chlorine on diphenyl containing chlorinated from monochlorobiphenyl to decachlorobiphenyl. HDF is gurbansolan to 10% in the last several years as transformer oil. They are prohibited for use as heat transfer fluids and plasticizers because of their toxicity. These substances are nonflammable, not soluble in water and have a low vapor pressure at ordinary temperature (0,006 mm RT.article or about 1.0 mg/m3). The maximum allowable concentration in the air of working zone (MAC) 1.0 mg/m3. After damage to the transformer, filled with sovtol or sovol, reuse, recent Smoking, so now accumulated a significant amount of this waste. Disposal by incineration or chemical treatment is very expensive.The solution to the problem of dehydration or disposal of these wastes is very important.Studies have shown that the introduction of chlorinated biphenyls in sleeper impregnation mixture can improve some indicators namely to raise the temperature of the flash and reduce watering. The minimum amount of diluent (1%) due to the effect of dehydration of antiseptic, and the upper limit (20%) kinematic viscosity of the composition.Waste electrical oils sovol and sovtol even after prolonged use (over 30 to 40 years) practically do not change their composition the proposed composition, had the following characteristics:
Density at 20oC 1.51 g/cm3< / BR>The viscosity at 20oC 10,6 mm2/s
Volatile at 100oC 0,13%
Experimental compositions were obtained by direct mixing of coal with waste oil electrical oil sovtol in different ratios at 50oC. Then, the composition was placed in an airtight vessel is heated, there was placed a sample of wood (pine) and spent the impregnation of the latter with the 90oC for 2 h under a pressure of 0.8 MPa.After impregnation the sample of wood was cooled and subjected to testing. Simultaneously conducted analysis of the impregnating mixture and the content of harmful substances in the air above the surface of the wood.For experimental verification of the proposed structure was made six mixtures.Example 1. Mixed 20% of waste electrical oils sovol and 80% coal oil. The mixture was stirred at 50oC. and Then impregnated with a mixture of a sample of wood at 90oC and a pressure of 0.8 MPa for 2 hExample 2. Mixed 1% of waste electrical oils sovol and 99% of the coal maltraitance oil sovol and 95% coal oil. Conditions of preparation and testing similar to example 1.Example 4. Mixed 15% of waste electrical oils sovtol and 85% coal oil. Conditions of preparation and testing similar to example 1.Example 5. Was mixed with 0.5% of waste electrical oils sovtol and 99.5% coal oil. Conditions of preparation and testing similar to example 1.Example 6. Mixed 25% of waste electrical oils sovtol and 75% coal oil. Conditions of preparation and testing similar to example 1.The table shows the properties of the resulting impregnating compositions and the test results.The test results show that the introduction of chlorinated biphenyls in coal oil can significantly increase the flash point of an impregnating composition, as well as to reduce the water content by increasing its density.Waste electrical oils do not find qualified use, disposal they are expensive. The proposed path disposal will allow you to get a considerable economic effect. So, sleeper impregnation plant processes in year 12 20 thousand tons of coal melhod 600 1000 t last.Currently preparing a batch of waste electrical oils to conduct pilot tests on Bogdanovichskii sleeper impregnation plant. The composition for impregnation of wood, including coal oil and diluent, characterized in that as a diluent it contains waste electrical oil-based chlorinated biphenyls - sovol or sovtol in the following ratio, wt.Coal oil 80 99
