The invention relates to the field of insulating materials and can be used for protection of underground facilities (pipelines, storage and other ), as roofing materials, sealing joints, cracks, protection of metals from corrosion and otherIn the world practice in the construction of pipelines, underground facilities and other widely used coatings, including epoxy powder composition, extruded or sprayed polyethylene, sticky polymeric tapes is isthmi have epoxy and polyethylene coating, but they are very expensive. More accessible and convenient for application of adhesive tapes, however, they do not have the required performance characteristics. Widespread coal and bituminous materials.Coal insulating materials used at the present time consist of thermoplastification in high-boiling oils coal and(or) coal tar pitch, coal oils, fillers (talc, carbon black (soot), coal, asbestos, rubber and other) and improving various properties of the composition additives [1-2]
The main disadvantage of coal enamels (upon receipt, the application and operation) is their high Carcinogenicity, because coal products (tar, pitches, and others) contain significant amounts of 2,4-benzpyrene.As a waterproofing materials are widely used petroleum bitumen mastic 
Closest to the claimed mastic mastic is isol  adopted for the prototype. Mastic isol is a multicomponent homogeneous mass consisting of rubber-bitumen binder (obtained thermomechanical treatment of vulcanized rubber or her regen is At 21-27-37-74). For the preparation of Isola use, for example, 56.2 per cent of bitumen, 18,9% rubber (tire reclaim), 3.5% rosin, 3.5% inden-coumarone resin, 14.9% of asbestos, of 1.1% coal oil and 1.9% of nefras (gasoline diluent).Physico-chemical characteristics of mastic isol below in table. 1.The disadvantages of this mastic refers to a relatively low cohesive ability, which greatly reduces the strength of the coating deposited on the solid material. In addition, the famous mastic is characterized by relatively high temperature flexibility, which leads to crack formation in the coating.The objective of the proposed technical solution is to increase the cohesive ability mastic relative to the solid material and the lowering of its temperature flexibility (improved elasticity).This problem is solved due to the fact that known waterproofing mastic, including an oil binder, gasoline diluent, coal oil, inden-coumarone resin, surface-active substances (SAS), as well as asbestos, rubber as a filler according to the invention contains as a binder a product of propane deasphalting, wt.Product propane deasphalting oil residues 41,0-61,5

The possibility of using product propane deasphalting oil residues (PDNA) brittina as a binder due to the significant content of resinous components (up to 57%). In at least astringent properties PDNA affect the contained oil. PDNA in the combination of a certain number of parallel layers, what determines the physico-chemical properties of the claimed composition and, first of all, the cohesive properties of mastic when applied to the surface of the solid material.In the inventive waterproofing mastic PDNA contains of 41.0-61.5% of the content PDNA in mastic below 41,0% resin has a low viscosity, poor adhesion to the filler that increases the temperature of flexibility and reduces the cohesion of the system of rigid material mastic solid material. When the content PDNA above 61,5% increases the viscosity of the mastic and temperature increases flexibility it on the rod. In the interval content PDNA 41,0-61,5% receive mastic with low temperature flexibility on the rod and high cohesion in relation to solid materials.As filler in the inventive mastic along with the previously known and used in the prototype asbestos-brand 7-450, GOST 12871-83, MEAs. 1, 2, 3, 4, and rubber (for example, the tire reclaim CS - OST 38.04307-88) use asphaltic.Asphaltic product deep obezbalivaniya oil residues, the content of asphalt-resinous substances which reaches more than 80% appearance asphaltic is a powdery product is brown or black color, easy comdev contained in the oil part, the higher the degree of dissolution of asphaltite.Asphaltic has the following average characteristics:

High content of asphaltenes in asphaltite (above 40%) contributes to the formation in the system with PDNA lamellar two-dimensional molecular compounds with optimal number (5-6) of parallel layers, which leads to lowering the temperature of the flexibility of the mastic on the web and increase its cohesion in systems with solid material.Asphaltic contained in mastic 0.8-9.0% of the content of asphaltite in mastic less than 0.8% dramatically decreases the cohesion of the mastic with a solid material. If the content of asphaltite in mastic exceed 9.0% of it has raised the fragility and the viscosity of the binder material, and matocha deformation). When the content of 0.8-9,0% asphaltite, and when 12,5-14,0% asbestos, the 15.6-19,0% rubber as filler receive mastic with optimal performance temperature brittleness and flexibility it on the rod and cohesion with solid material.As plasticizing additives in the inventive compositions use a known prototype inden-coumarone resin (TU 14-6-72-89) and coal oil (GOST 2770-74, MEAs. 1, 2, 3), which also has antiseptic properties, and proposed to enter the polyvinyl chloride in the amount of 1.0 to 5% Quality PVC skin corresponds marks PVC-With-7059-M and PVC-With-7056-M GOST 14332-78 that have the same constant values of Petenera (70-73) and a bulk density of 0.45-0.55 g/cm3but differ on the time of absorption of the plasticizer respectively not more than 10 and 25 min, the mass of absorbed plasticizer is not less than 54 and 17 g/100 g PVC, the mass fraction of moisture and volatile matter not more than 0.30 and 0.50%, respectively. Thermostability at 160oC for the brand PVC-With-7059-M must be at least 10 min and brand PVC-With-7056-M is not specified.When the content of polyvinyl chloride in mastic below 1.0% and above 5% deteriorates the cohesion of the mastic with solid materials and uvelichivala with high cohesion relative to the solid material and low temperature flexibility at the core.In the composition of the claimed mastic (song) injected surfactant (for example, synthetic fatty acid raw on THE other 38.107105-77, MEAs. 1, 2, 3) in an amount of 0.5 to 2.0% which can be applied mastic without prior drying of the surface of the processed material.As gasoline diluent can be applied Nefras C2 80/120 according to GOST 443-76 ISM. 1, 2.Proposed composition of the waterproofing mastic can improve the cohesion of the mastic with a hard surface with a stated ratio of the components, as evidenced by the following examples, which indicate the possibility of implementation of the proposed invention.Example 1. Hydroisolation mastic is produced by mixing the components in the following ratio, wt. PDNA 61,5, coal oil 0,7, inden-coumarone resin 5,5, asbestos 12,5, rubber 15,6, asphaltic 0.8, PVC 1,0, surfactants, 0.5 to Nefras (petrol solvent) of 1.9.The components are mixed mastic was conducted on a laboratory mixer type TP-A the capacity of 1 kg/h of the First in the running mixer downloaded the propane product of deasphalting at 20oC, and then gradually filling the filler (asbestos, rubber, asphaltic, Polga in the composition of the mastic (coal oil, inden-coumarone resin, surfactant). The mixture was stirred 3 hours After receiving the above mixture to it was added tire regenerator (rubber), expanded into a thin sheet together with inden-coumarone resin, rubber, cut into small pieces. The mixture was stirred for 8 hours then after 10-15 minutes in the mixer was introduced inden-coumarone resin, the mixture was stirred for another 90 min and used.The obtained resin has a softening temperature at Kish 60,0oC, the temperature of the flexibility of the sample at a bend in the rod diameter 20 mm -20oC, the cohesion of the concrete-grout-concrete 7,0 kg/cm2concrete-mastic-metal 8,7 kg/cm2the metal-resin-metal 16,5 kg/cm2(see tab. 2).Examples 2-3 performed analogously to example 1. Compounds mastics and their quality are given in table. 2.The table shows that the proposed mastic compared with the prototype has a high cohesion in relation to concrete, metal and low temperature flexibility at the core.Thus, using the proposed mastic as knitting product propane deasphalting oil residues that interact when mixed with the above components (PVC, asphaltic isolational mastic.
