Abstract

The invention discloses a modified asphalt waterproof coiled material and a preparation method thereof. The modified asphalt waterproof coiled material is prepared from the following raw materials: Buton rock asphalt, bisphenol-A epoxy resin, high-density polyvinyl chloride, SBS (Styreneic Block Copolymers) rubber, butadiene styrene rubber, coumarone resin, SBR (Styrene Butadiene Rubber), naphthenic rubber oil, vinyl trichloro silane, butylated hydroxyanisole, epoxypropane butyl ether, benzophenone, calcium carbonate, powdered carbon, magnesium hydroxide, aluminum hydroxide, diatomite, talcumpowder, phenyl salicylateo-hydroxybenzoic acid phenyl ester, cerium oxide, antimony trioxide, a PE (Polyethylene) membrane and polypropylene fabric. The modified asphalt waterproof coiled material isprepared by the following steps: preparing a base material; preparing a modified material; then mixing a main material with the modified material, and extruding the mixture out of a tire bodyinto a carcass through a screw extruder; extruding the mixture through a roller; compounding the polypropylene fabric and the carcasstire body into a whole by hot pressing; cooling; lastly, attaching the PE membrane to the surface in order to form the waterproof coiled material. The waterproof coiled material disclosed by the invention has superior high-temperature resistance and ultraviolet ray resistance.

Description

【Technical field】 [0001] The invention belongs to the technical field of coil preparation, and in particular relates to a modified asphalt waterproof coil and a preparation method thereof. 【Background technique】 [0002] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of road bridges, roofs or buildings that need to be waterproofed, waterproof membranes need to be laid in advance. According to its main waterproof composition materials, it can be divided into three categories: asphalt waterproof materials, polymer modified waterproof membranes and synthetic polymer waterproof membranes. Among them, asphalt waterproof membranes are the most commonly used waterproof membranes, accounting for the total market share. The effect of 70% of the amount, this coil is actually a rollable sheet-shaped waterproof material made by dipping asphalt on the base tire and then spreading powder or sheet-shaped isolation materials on...
