METHOD OF SYNTHESIS OF VIBRATION-ABSORBING MASTIC Russian patent published in 1995 - IPC

Abstract RU 2044016 C1

FIELD: mastics. SUBSTANCE: method involves addition of polyvinyl acetate to the aqueous dispersion containing dry matter at concentration 50-6- wt.-% alkylbenzylpyridinium chloride of the following formula: where n 2-5. Then plasticizer (glycerol dibutylphthalate or triacetate), nepheline antipyrene and fillers (chalk and vermiculite) were added. Components were used at the following ratio, wt.-% polyvinyl acetate dispersion 35.3-66.7; plasticizer 3.30-8.35; nepheline antipyrene 6.7-18.6; vermiculite 8.6-29.4; chalk 2.0-14.5, and alkylbenzylpyridinium chloride 0.5-4.9. EFFECT: improved method of mastic synthesis. 2 tbl
