Then prepare a filler consisting of foundry graphite GL-1(GOST 17022-81), solution of the dispersant is sodium tripolyphosphate (TU 2148-095-43499406-98) and nepheline flame retardant (TU 6-08-340-76). Then produce a mixing of prepared ingredients in the mixer and stores thus obtained suit the value of the tangent of mechanical loss, that largely depends on the temperature that must be considered when operating products using coatings of vibration mastics.To define the properties stated mastics were prepared several compounds (table. 1).The dependence of the vibration-absorbing properties of the claimed composition on temperature are given in table. 2.From table.2 shows that the claimed mastic has a sufficiently high vibration damping properties. The introduction of the mastic dispersant (sodium tripolyphosphate) provides an additional increase in vibration-absorbing properties of mastic compared with sample 4, in which the dispersant is missing.In the claimed mastic used cheaper compared with dibutyl phthalate plasticizer "Ados", which has III hazard class. This provides an improvement of the hygienic characteristics of the coating and the possibility of using the claimed mastic for a wider class of products.The industrial applicability of the claimed technical solution is confirmed by the successful results of experimental use of the claimed compositions, which can be manufactured with the required criterion "industrial applicability".Using the stated solution provides improved vibration damping properties of mastic, the improvement of the hygienic characteristics of the coating and the possibility of using the claimed mastic for a wider class of products. 1.
