Abstract

The invention relates to the preparation of mastic compounds used for sealing joints and waterproofing coatings. The invention allows to increase adhesion, frost resistance, processability and reduce water absorption and fluidity by using 5-15 wt.h. as a filler of chrysotile asbestos. and grinding dust - waste production of asbestos products 5-15 wt.h. and additionally VAT residue of the rectification column of the return isopentane-isoprene fraction in the production of isoprene rubber based on isoprene oligomer (mol.m..200-300) 5-40 wt.h. in the composition of the composition, parts by weight: varnish HP-734 based on chlorosulfonated polyethylene 15-80, bitumen 5-45. The composition may additionally contain N, Nb-diphenylparaphenylenediamine 0.2-0.7 wt.h. 3 tab.
