Abstract

The invention discloses a hot-melt elastomer modified asphalt waterproof coiled material and a preparation method thereof. The upper surface modified asphalt layer of the waterproof membrane of the present invention is formed by high-density modified asphalt, and the lower surface modified asphalt layer is formed by high-density modified asphalt with an inverted isosceles trapezoidal cross-sectional pattern in the thickness direction of the waterproof membrane and Low-viscosity modified asphalt whose cross-section is isosceles triangle is alternately coated; in parts by weight, high-density modified asphalt: 100-140 parts of asphalt, 0-10 parts of softener, 10-30 parts of SBS, thickening 10-20 parts of modifier, 3-8 parts of modifier, 1-5 parts of defoamer, 20-40 parts of filler; low viscosity modified asphalt: 80-120 parts of asphalt, 10-30 parts of softener, SBS 5 ‑15 parts, modifier 15‑25 parts, viscosity reducer 2‑6 parts, filler 30‑60 parts. The waterproof coiled material of the invention has excellent low-temperature flexibility, fusibility and water resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a hot-melt elastomer modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] SBS thermoplastic elastomer first appeared in the United States in the early 1960s, and soon developed SBS modified asphalt in France and named it elastic asphalt. Because SBS modifier has a variety of excellent characteristics, it spread rapidly in Europe and spread to Japan and the United States. Currently, SBS is still the first choice for modified asphalt materials. The combination of SBS elastomer modified bitumen and filament polyester non-woven fabric makes the performance of SBS modified bitumen waterproof membrane more perfect and enters the ranks of high-grade waterproof materials, and is widely used in the field of waterproofing. In countries such as Germany, France, Finland and Norway, SBS modified bitumen waterproofing membrane accounts ...
