Abstract

The invention relates to the technical field of waterproof materials and particularly relates to a preparation method of a nanoscale filler modified non-asphaltic waterproof material. The material comprises the following raw materials in parts by weight: 25-45 parts of rubber oil, 1-5 parts of hot melt adhesive elastomer, 1-11 parts of styrene-butadiene-styrene segmented copolymer, 1-8 parts of tackifying rubber, 4-16 parts of desulfurization rubber powder, 5-8 parts of high temperature resin, 10-25 parts of tackifying resin, 4-35 parts of nanoscale talcum powder and 1-2 parts of white carbon black powder. The preparation method comprises the steps of infiltrating the rubber oil into a proportioning reaction kettle; heating to 195-200 DEG C to remove water inside; adding desulfurization rubber powder to grind; adding the hot melt adhesive elastomer, the styrene-butadiene-styrene segmented copolymer and the tackifying elastomer; adding the high temperature resin and the tackifying resin to stir and dissolve; after half an hour, adding the nanoscale talcum powder and the white carbon black powder; then, uniformly stirring and cooling to prepare the waterproof material. The material has good self-curing and stripping performances.
