Abstract
The invention provides a self-adhesivepolymer modified bituminous polyesterfiber 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: 37-47 parts of bitumen, 8-18 parts of machine oil, 5-10 parts of SBSrubber, 2-12 parts of SBR rubber, 2-12 parts of EPDM rubberpowder, 2-7 parts of butyl rubberpowder, 25-35 parts of talcpowder and 1-10 parts of petroleum resins. The bitumen is 90# one. The invention has the effects as follows: the waterproof sheet material uses the EPDM modified bitumen as the base material and polyester cloths as the matrices; the back of the adhesive side is covered by the reinforced self-adhesive waterproof sheet material of abherent, thus achieving the effect of sticking while adhering and improving the construction efficiency; 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.
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...
