Abstract
The invention provides a self-adhesive rubber bituminous waterproof sheet material and preparation technology thereof. The waterproof sheet material comprises polyester cloths, an immersion oil coating layer and a film-mulching layer. The immersion oil comprises the following materials in parts by mass: 43-52 parts of bitumen, 5-15 parts of machine oil, 3-13 parts of SBS rubber, 3-13 parts of SBRrubber, 3-13 parts of EPDM rubber powder, 3-8 parts of butyl rubber powder, 15-25 parts of talc powder and 1-10 parts of petroleum resins. The bitumen is 90# one. The invention has the effects as follows: the waterproof sheet material can achieve the effect of sticking while adhering and improve the construction efficiency obviously; the waterproof sheet material is characterized by solvent-free construction, safety and no scald; the waterproof sheet material has shining surface and good elasticity, and the properties of the waterproof sheet material are not obviously changed after aging through laboratory test. The waterproof sheet material is suitable for waterproofing works of basements of industrial and civil buildings, subways, accumulated water in tunnels and the like, is also suitable for waterproofing of roofing of non-exposed buildings and is especially suitable for works which are characterized in that solvents and open fire are not allowed on the construction site.
Description
technical field [0001] The invention relates to a building waterproof coiled material and a preparation process of the waterproof coiled material. Background technique [0002] Waterproof membrane is a commonly used building material in building construction. In underground engineering and water conservancy engineering construction, waterproof membrane is of great significance to reduce leakage and withstand high water pressure. The existing EPDM waterproof membrane has excellent properties such as high strength, high elongation, high tear strength, high and low temperature resistance, ozone resistance, and aging resistance, so it is widely used in building construction. However, after the existing EPDM waterproofing membrane is laid, the waterproof base material cannot be closely combined with the building base, and water leakage is easy to occur. In case of local water seepage in the waterproof layer, it will also cause "water channeling" under the entire waterproof layer...
