Problems solved by technology

[0002] In the patent with the application number "2012105340138" and the name "a self-adhesive waterproof material and its manufacturing method", a method of manufacturing a waterproof material is disclosed: the waterproof material is prepared from the following substances: softening oil 25-50 %, hot melt adhesive grade elastomer 0~5%, styrene-butadiene-styrene block copolymer 1~9%, tackifying rubber 0~5%, waste rubber elastomer 8~18%, UV protection 0.1-0.5% of additives, 5-8% of high-temperature resins, 10-25% of tackifying resins, 0.1-0.15% of interface agents, and 4-44% of pigments and fillers. It has strong weather resistance. For example, the widest application range is : The advantage of not breaking at -25 degrees and not flowing at 70 degrees, the peeling performance of such waterproof materials is 2-3 times that of traditional asphalt-based materials, that is, it has better peeling performance, but it is more demanding On the other hand, once such a waterproof material cracks, repairing the cracks requires cumbersome processes such as cleaning, high temperature, and pressing, and has the disadvantages of poor self-healing and easy rupture along old scars.

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.
