The invention relates to adhesive compositions based on polychloroprene rubber and can be used in the rubber industry for bonding vulcanized rubbers on the basis of different rubbers to each other. Known adhesive composition comprising a chloroprene rubber, thiuram, zinc oxide, as the resin product of co-condensation of phenol acetaldehyde and acetonaphthone and the solvent (USSR Author's certificate No. 1579920, CL C09J 111/00; publ. 23.07.90). As solvent a mixture of ethyl acetate and petrol. However, this adhesive composition does not provide a sufficiently high strength for bonding articles of vulcanized rubber. Known adhesive composition comprising polychloroprene rubber, epoxy resin, low molecular weight on BNR rubber, tertiary amine, and a solvent (USSR Author's certificate No. 685673, CL C08L 11/00; publ. 15.09.79). However, this adhesive composition has a low strength bonding of rubber products based on various rubbers. Known adhesive composition comprising polychloroprene rubber, butylbenzaldehyde resin, a copolymer of styrene and piperylene, rosin, esterified with glycerol, pine rosin, diphenylguanidine, 2,2-dimensionalised, zinc oxide, magnesium oxide, organic dissolve the spruce (U.S. Pat. 2028358 Russia, MKI6C09J 111/00; publ. 09.02.95). However, this adhesive composition, although it has a similar composition, used to glue products from ferrites. Closest to the invention to the technical essence is the glue SU (TU 381051760-89), which includes (parts by weight): polychloroprene rubber Nairit DP - 90,0, butylbenzaldehyde resin C - 90,0, zinc oxide - 5.0, magnesium oxide - 11,0, water - 3,0, organic solvent - 800,0. As the organic solvent, a mixture of nefras and ethyl acetate in a percentage ratio of 50:50. However, this adhesive composition (although it is widely used because of its low cost) does not provide a sufficiently high strength for bonding vulcanized rubber (attainable shear strength for bonding vulcanized rubber-based composition of polyisoprene rubber (SKI-3) does not exceed 0.43 MPa). Task: development of the composition of the adhesive composition having increased strength in bonding vulcanized rubber between them. The technical result is to increase the strength of the bonding vulcanized rubber between them. The technical result is achieved in that the adhesive composition comprising polychloroprene rubber Nairit DP, butylbenzaldehyde resin C, the water, the led of zinc, magnesium oxide, an organic solvent which is a mixture of ethyl acetate and nefras, further comprises a modifier, previously obtained as a result of interaction at room temperature aliphatic amine is triethanolamine or polyethylenimine and filler silica Rosil brand R-175 in the following ratio, parts by weight: polychloroprene rubber Nairit DP - 90,0, butylbenzaldehyde resin C - 90,0, water - 3,0, zinc oxide - 5.0, magnesium oxide - 11,0 specified organic solvent - 800,0, aliphatic amine is 0.1 to 0.2, the silica filler Rosil brand P-175 - 10,0. Polychloroprene rubber Nairit DP (TU-6-01-1319-85) is the main film-forming adhesives-solutions. Butylbenzaldehyde resin C (TU-60004691277193-97). Curing group: zinc oxide (zinc white GOST 202-84), magnesium oxide (burnt magnesia GOST 844-79) was previously used in the adhesive compositions (Kardashov D.A., Petrov A.V. Polymer adhesives. M.: Chemistry, 1983). Organic solvent: a mixture of ethyl acetate (GOST 8981-78) and nefras (GOST 3840167109-92). Triethanolamine (TU 2423-061-05807977-2002) is used for gas purification in obtaining pure carbon dioxide, textile and cement industries, in the manufacture of Metalworking fluids, cosmetics, household chemicals as raw materials in organic the ish synthesis. The polyethylenepolyamine (TU 2413-214-00203312-2002) is used as raw material for the production of active fundamentals of corrosion inhibitors, epoxy compounds, aminecontaining resins as curing agent of epoxy resins, varnishes and paints, detergents and additives. The filler is silica Rosil brand R-175 (Rosel-175) (TU 2168-038-00204872-2001) is a fine precipitated silica. Used for the production of tires, rubber products, artificial leather, paint, oil industry. Modifier receive a direct interaction of aliphatic amine and silica filler Rosil brand P-175, at room temperature for 1 hour. The modifier is a viscous mass of white. When using this modifier increases the adhesive properties of the adhesive composition. This is due to the increase of the content in the adhesive composition of functional groups. As a result of interaction of the specified modifier with macromolecule polychloroprene rubber is an increase in the concentration of polar groups and the formation of additional chemical bonds, which increases the mobility of the macromolecules polychloroprene and deeper diffusion areas of the interior surface of the vulcanizate. This explains the higher is their strength when bonding of vulcanized rubbers to each other. The adhesive composition is prepared as follows. In the beginning prepare a rubber compound S-1-GN - a mixture of plant APS, magnesium oxide, zinc oxide (ETP 8857-91) in the rubber mixer for 10 minutes, the temperature of the mixer gradually increases as you enter the components of the mixture) from 50°C to 85°C. After discharging the mixture at a temperature of 105°C is carried out by listomania for 5 minutes Then heated rubber mixture with part of the solvent (about 0.1 of the total amount of the solvent is loaded into clearesult. Remaining solvent together with other ingredients of the adhesive composition butylbenzaldehyde resin, water, modifier loaded portions in clearesult as swelling rubber compound. Total time clemmesen is 4.5-5 hours, with the introduction of the modifier can be carried out after preparation of the adhesive composition on the basis of the remaining components. An example of the preparation of the adhesive composition. In clearesult containing prepared in a known manner naritaweg glue SU (TU 381051760-89), comprising polychloroprene rubber Nairit DP, butylbenzaldehyde resin C, zinc oxide, magnesium oxide, water and a specified organic solvent, enter the calculated amount in the specified modifier and mix the contents 5-10 minutes before proceneonate mass. Receive adhesive compositions 1-4, the compositions of which are given in table 1. Glue is a liquid beige color. Adhesive tech, well put on the rubber surface. Have been investigated by various contents of the specified modifier (table 2). Stated number of components of the modifier aliphatic amine of 0.1 - 0.2 and the silica filler Rosil brand P-175 - 10,0 due to the fact that when you increase or decrease the indicated dosages bond strength when bonding is reduced. Comparative tests of strength properties of adhesives in all variants of the claimed composition and the prototype for bonding vulcanized rubber-based composition of polyisoprene rubber (SKI-3) and chloroprene rubber (Neoprene) are given in table 2. For the comparative tests was prepared 4 types of compositions (according to the method described in the example) and the composition of the prototype presented in table 1. The proposed composition was studied on the adhesion strength shear achieved through keeping under load of 2 kg at room temperature (20°C) within 24 hours. The data presented in table 2, which shows that the proposed composition surpass the prototype values of shear strength. Adhesion shear was determined on a tensile testing machine MPC - 250 (RTM 1.2.126-88). is the technology pasting the following samples. One-time application of the prepared adhesive to the prepared surface, drying the adhesive film at room temperature (20°C) for 1-2 minutes, then made a tight pressing of the bonding surfaces. As can be seen from table 2, the proposed adhesive compositions provide enhanced strength properties of adhesive joints in comparison with the prototype. Thus, the shear strength of the adhesive joint for bonding vulcanized rubber-based Neoprene prototype is 0.75 MPa, and with the use of the modifier of 1.02 MPa (composition 3). Thus, when using the proposed adhesive compositions within these limits increases the strength of bonding of the articles of vulcanised rubber other on the basis of various rubbers, due to the participation of this modifier in improving the adhesion properties of the adhesive. We found that the reason for increasing the adhesion performance of the adhesive composition is not only an increase in the concentration of the polar groups with the introduction of the modifier, but the formation of additional chemical bonds in the interaction of the specified modifier with movable allylic chlorine atoms in macromolecules polychloroprene rubber, which leads to an increase of the density of a spatial grid and, apparently, to the hardening of the adhesive film./p>
Technical and economic effect, resulting from the application of the adhesive compositions is that its use can significantly improve the quality fastening products, of vulcanised rubber other on the basis of different rubbers. The adhesive composition comprising polychloroprene rubber Nairit DP, butylbenzaldehyde resin C, water, zinc oxide, magnesium oxide, organic solvent which is a mixture of ethyl acetate and nefras, characterized in that it further comprises a modifier, previously obtained as a result of interaction at room temperature aliphatic amine is triethanolamine or polyethylenepolyamine and filler silica Rosil brand R-175 in the following ratio of components, parts by weight:
