Abstract

The invention provides a non-asphalt-based pre-paved waterproof coiled material with high water soaking resistance and a preparation method thereof. The non-asphalt-based pre-paved waterproof coiled material comprises a polymer sheet layer, a polar hot-melt pressure-sensitive adhesive layer and a strong-hydrophobicity isolation sand layer, and the polar hot-melt pressure-sensitive adhesive comprises the following raw materials: SIS, naphthenic oil, first polyisobutene, second polyisobutene, hydrogenated C5 petroleum resin, styrene modified terpene resin, phenolic modified resin, modified maleic resin, an antioxidant, an ultraviolet light absorber and a light stabilizer. The high-hydrophobicity isolation sand is inorganic mineral particles treated by coupling agent hydrolysate. The prepared non-asphalt-based pre-paved waterproof coiled material has the characteristic of excellent water soaking resistance, after being soaked in water for 180 days, the isolation sand covered on the coiled material is still not easy to fall off, and the bonding surface at the lap joint can still keep a good bonding state, so that the good construction application performance of the coiled material is ensured.

Description

Technical field[0001]The present invention relates to the field of waterproof web technology, and more particularly to high water soaking non-orteenyl preparation waterproof web and preparation methods thereof.Background technique[0002]Non-asphalt base preparation waterproof coils were first invented by the US Grace Waterproof Company and brought into the Chinese market. Subsequently, the country has released relevant standards in 2008, vigorously promoting the preparation of waterproofing coil system and construction technology. At this stage, there are many cities in my country to carry out underground integrated gallery construction and tunnel engineering construction, providing non-orphal-based polymer waterproof coils. A wide range of applications.[0003]After the non-asphalt-based pre-paving waterproof coil is fixed, it is necessary to laid the steel bar, or the construction period is delayed and the concrete cannot be placed immediately. It is likely to be exposed to the natur...
