Abstract

The invention provides a styrene butadiene styrene (SBS) modified bituminous waterproof sheet material and preparation technology thereof. The waterproof sheet material comprises polyester cloths, animmersion oil coating layer and a film-mulching layer. The immersion oil coating layer comprises the following materials in parts by mass: 32-52 parts of bitumen, 12-22 parts of residual oil, 9-19 parts of EPDM rubber powder, 2-7 parts of butyl rubber powder, 11-21 parts of talc powder and 5.6-10.6 parts of SBS rubber. The bitumen is the mixture of 9-19 parts of 10# bitumen and 23-33 parts of 60#bitumen. The invention is characterized by wide high temperature and low temperature resistance range, good elasticity and good hardness, is not easy to deform and is suitable for various levels of waterproofing works of roofing of industrial and civil buildings, underground, bridges, highways, swimming pools and the like in the south and in the north.

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...
