Abstract

The invention discloses an asphalt composite matrix flexible waterproof coiled material. The asphalt composite matrix flexible waterproof coiled material comprises a matrix layer B, an upper surface layer A bonded with the matrix layer B, and a lower surface layer C bonded with the matrix layer B; the upper surface layer A is bonded with the matrix layer B with a modified asphalt, and the matrix layer B is bonded with the lower surface layer C with the modified asphalt; the matrix layer B is prepared from non-woven fabric; the upper surface layer A is prepared from a polyethylene film, a high temperature-resistant polyester film, or fine sand; and the lower surface layer C is prepared from a polyethylene film. A preparation method of the modified asphalt comprises following steps: straw powder is added into a sulfuric acid solution for heating and stirring; epoxy chloropropane and hydrogen peroxide are added for uniform stirring and heating so as to obtain a modified straw powder; the modifier straw powder, zeolite powder, sepiolite, waste tire rubber powder, ether, and aluminium-zirconium coupling agent are uniformly mixed and are subjected to microwave treatment so as to obtain a modified rubber powder; asphalt is heated, the modified rubber powder, SBS, and machine oil are added for uniform stirring, an obtained mixture is subjected to oxidation polishing, and talcum powder and calcium sulfate whisker are added for uniform stirring so as to obtain the modified asphalt.

Description

technical field [0001] The invention relates to the technical field of waterproof rolls, in particular to a flexible waterproof roll with asphalt composite tires and a preparation method thereof. Background technique [0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, mainly including asphalt Waterproof membrane and polymer waterproof membrane. Bitumen waterproofing membrane is a rollable sheet waterproof material made by spreading asphalt on the base tire (such as base paper, fiber fabric) and then spreading powder or sheet isolation material on the surface. Commonly used insulating materials are generally powdery or flake-like inorganic materials, such as talcum powder, crushed stone powder, and the like. Isolation materials and asphalt can only serve the purpose of isolation, and cannot improve the...
