Abstract

The invention belongs to the technical field of building waterproof engineering and particularly relates to a self-adhesive waterproofing coiled material cementing material and its preparation method and a waterproofing coiled material prepared from the self-adhesive waterproofing coiled material cementing material. The self-adhesive waterproofing coiled material cementing material is prepared from 46 to 55 parts by weight of type I waterproofing coiled material asphalt, 6 to 9 parts by weight of SBS, 6 to 15 parts by weight of waste rubber powder, 8 to 12 parts by weight of aromatic oil, 5 to 10 parts by weight of tackifying resin, 4 to 9 parts by weight of ethylene bis-stearamide and 10 to 25 parts by weight of nanometer calcium carbonate. The preparation method solves the problem that the traditional method for preparing a waterproofing coiled material from SBR butadiene styrene rubber powder easily produces clustering and blocks a pipe. The processing temperature is low so that the production time of the self-adhesive waterproofing coiled material is greatly reduced and a production cost is reduced. The self-adhesive waterproofing coiled material cementing material has good waterproofing properties, high tensile strength, good extensibility, excellent low-temperature flexibility and heat resistance.
