Abstract

The invention relates to a waste rubber composite modified asphalt waterproof material and a preparation method thereof. The waste rubber composite modified asphalt waterproof material sequentially comprises an upper surface isolation layer, an upper polymer modified asphalt layer, a tire basic layer, a lower polymer modified asphalt layer and a lower surface isolation layer from top to bottom, wherein the upper polymer modified asphalt layer and the lower polymer modified asphalt layer are prepared from waste rubber composite modified asphalt; the waste rubber composite modified asphalt is prepared form the following raw materials in parts by weight: 60 to 70 parts of petroleum asphalt, 10 to 20 parts of SBS (Styrene Butadiene Styrene) rubber, 5 to 10 parts of SIS (Styrene Isoprene Styrene) rubber, 10 to 20 parts of waste rubber powder, 2 to 3 parts of an asphalt modifier, 1 to 3 parts of a modified asphalt stabilizer, 0.1 to 0.3 part of graphene, 1 to 3 parts of sulfur, 0.5 to 0.8 part of petroleum sulfonate, 1 to 3 parts of succinic anhydride, 1 to 3 parts of wood vinegar, 3 to 5 parts of inorganic filler and 1 to 3 parts of metal oxide. According to the waste rubber composite modified asphalt waterproof material and the preparation method thereof, disclosed by the invention, an asphalt modification compatilizer is preferably selected, the compatibility of the waste rubber powder and the asphalt is effectively increased, and the prepared waterproof material has excellent high-temperature stability, excellent low-temperature crack resistance, aging resistance, durabilityand the like.

Description

technical field [0001] The invention relates to a waste rubber composite modified asphalt waterproof material and a preparation method thereof, belonging to the field of asphalt waterproof coiled materials. Background technique [0002] SBS modified bitumen waterproofing membrane refers to polyester felt or glass fiber felt as base, styrene-butadiene-styrene (SBS) copolymerized thermoplastic elastomer modified bitumen as coating material, both sides covered with polyester Modified bitumen waterproofing membrane made of vinyl film, fine sand or mineral aggregates. However, the modification by SBS is costly and unfavorable for popularization and use. At present, the production of a large number of automobile waste tires is increasing and the waste rubber particles obtained by crushing them can be used as modifiers to improve the performance of asphalt in various aspects, which not only solves the pollution problem caused by waste tires, but also can achieve waste The recycli...
