(57) Abstract:The invention relates to the field of vibration damping compositions for coatings, in particular for in-situ coating of marine areas. Mastic contains, wt%: 39,4-56,0 aqueous polyvinyl acetate dispersions, plasticized with dibutyl phthalate or triacetate of glycerol; 11.8 to 19,0 nepheline flame retardant; 26,0-42,0 crystalline graphite. What's new is that the mastic to improve the stability further comprises, in wt.%: 2,2-8,0 chalk and 0.5-4.6 alkylbenzyldimethylammonium. table 2. The invention relates to the field of production and application of vibration damping compositions for coatings, in particular for in-situ coating areas of the vessel.Known vibration-absorbing resin, comprising, by weight. 42,6-51,6 plasticized polyvinyl acetate dispersion (PVAD), from 9.6 to 10.6 nepheline flame retardant (); 32,3-34,0 crystalline graphite (KG) and 6.5-12.8 chloroparaffin 
Floor it has a complex good operating characteristics: high vibro-acoustic performance, excellent adhesion, low inflammability. However, the stability of the main vibroacoustic properties in time he nedolgim currently norms average life of the vessel is 20-25 years).The technical essence and the achieved effect is closest to the invention is a vibration-absorbing resin, comprising, by weight. 45,5-50,0 water PVAD; plasticized with dibutyl phthalate (DBP); 14,0-18,0 ON and 36,0-40,0 KG  Floor it has a complex of valuable operational characteristics: high, stable in time (for 3 year loss ratio decreased by not more than 8-12%) vibroacoustic characteristics, excellent adhesion, low inflammability. However, the stability of the most important technological properties of the mastic is not high enough. After 3-5 days from the date of manufacture mastic begins to noticeably lose their mobility, and after a month of storage the value of this indicator falls approximately three times. This is a very serious lack of technological material, negative consequences of which are:
the complexity of rubbing mastic from storage reservoirs (to avoid premature irreversible drying out mastic as any composition based on water PVAD, must be kept in a sealed container). Thick mastic literally have to pick out from cans and drums low operation beyond MGU from cans crumb's almost impossible (even after prolonged stirring and adding additional quantities of water) to turn into a smooth paste what is freshly made mastic. Hence the problem with mastic on temperame surface lumps substantially hinder spacelane and day exclude mechanized spraying, as they constantly clog the nozzle of the spray device;
vibroacoustic damping performance of the coatings of the famous mastic prototype stored for one month in the normal plant conditions, 25-30% lower than that of the coatings of the freshly prepared material.Because engineering plants it is difficult to provide immediate full use fresh mastic, the task of improving the stability of its technological properties is one of the most important.The aim of the invention is to increase the stability of the technological properties of the vibration-absorbing putty in time.This objective is achieved in that the vibration-absorbing resin, comprising water plasticized polyvinyl acetate dispersion, nepheline flame retardant and crystalline graphite, additionally contains chalk and alkylbenzyldimethylammonium (ABP) in the following ratio, wt.Water PVAD, plasti-
