Reaction sticky asphalt waterproof sheet material and preparation method thereof

Abstract

The invention relates to a reaction sticky asphalt waterproof sheet material, which comprises a first insulating film, a first reaction sticky asphalt waterproof layer, a polyurethane padding base layer, a second reaction sticky asphalt waterproof layer and a second insulating film, which are arranged from top to bottom; the first reaction sticky asphalt waterproof layer and the second reaction sticky asphalt waterproof layer are prepared from the same components in parts by weight: 2900 to 3100 parts of 90 # asphalt, 280 to 320 parts of 10 # asphalt, 850 to 950 parts of engine oil, 950 to 1050 parts of polyethylene, 15 to 25 parts of petroleum resin, 15 to 25 parts of coupling agent, 450 to 490 parts of rubber powder, 2300 to 2500 parts of stone powder, 293 to 307 parts of SBS and 890 to 910 parts of SBR. The SBS and the SBR are combined for use, and thus the sticky property of the reaction sticky asphalt waterproof sheet material is improved.

Description

technical field [0001] The invention relates to the field of building waterproof materials, more specifically, it relates to a reaction-adhesive asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] At present, due to the improper selection of waterproof materials on the surface of buildings in humid environments, water seepage often occurs on the surface of the building, resulting in corrosion of steel bars inside the building, spalling of concrete pavement, alkali-aggregate reaction, and concrete expansion caused by steel bar corrosion. The damage problem seriously affects the durability of the building and the normal service life of the building. Therefore, the waterproofing of buildings, especially the waterproofing of buildings in humid environments, has attracted increasing attention. In the process of traditional building construction, waterproof materials are generally divided into two categories: coiled materials and coa...

Problems solved by technology

[0003] However, the construction thickness of the waterproof coating is not easy to control; it is firmly combined with the base surface, and it is easily affected by cracks in the base surface to cause stretching and cracking; most coatings are not easy to use in long-term water-immersed environments, and are not easy to use in places exposed to sunlight; construction It needs to be painted many times, the construction period is long, and solvents are easily generated during the construction process, polluting the environment and other problems.

[0004] At the same time, the biggest obstacle in the use of membrane waterp
