Problems solved by technology

[0003] The seam peeling strength refers to the maximum strength when the lap between the coiled material and the coiled material is torn, which reflects the performance of the coiled material. The existing waterproof membrane has a single raw material formula and a simple process. After construction, the seam peeling strength Poor, when the base layer swells, it will be pulled apart at the lap joints, and the lap joints will fail, causing water seepage at the joints, making the waterproof layer of the building face severe challenges, and even suffer damage

Abstract

The invention provides a high-strength and anti-stripping elastomer modified asphalt waterproof coiled material. The high-strength and anti-stripping elastomer modified asphalt waterproof coiled material comprises a base material taking a reinforced long fiber polyester base material as a main material and further comprises the following components in parts by weight: 60-70 parts of petroleum asphalt, 3-6 parts of nano-TiO2 powder, 6-9 parts of styrene-butadiene-styrene block copolymer (SBS), 1-5 parts of C9 petroleum resin, 2-5 parts of stabilizer, 2-6 parts of AMR anti-stripping agent and 15-20 parts of talcum powder. The high-strength and anti-stripping elastomer modified asphalt waterproof coiled material provided by the invention has the advantages of relatively high waterproof effect, high stripping strength of lap joints after hot melt construction, effect of being less prone to causing cracking of the lap joints, relatively high tensile capacity, relatively good low-temperature softness and high water impermeability.

Description

technical field [0001] The invention relates to the technical field of waterproof membranes, in particular to a high-strength peel-resistant elastomer modified asphalt waterproof membrane and a production process. Background technique [0002] Elastomer-modified asphalt waterproofing membranes are clearly used in roofing and underground waterproofing projects of grades I and II of waterproofing membranes. The products are widely used in France, Germany, and Northern Europe. They are mainly used in roofs, basements, toilets, Buildings such as bridges and swimming pools are waterproof. Japan and the United States also use elastomer-modified asphalt waterproofing membranes. Elastomer-modified asphalt waterproofing membranes have become the first material for waterproofing projects, which not only changed the urban landscape, but also improved the drainage and insulation of the roof. Thermal performance, high-performance elastomer modified bitumen waterproof membrane has become ...
