Problems solved by technology

From this point of view, the elastomer-modified asphalt waterproof membrane (SBS) technology produced in China is basically mature at this stage, but there are still many problems. Due to the inaccurate dosage during the batching process, the instability of temperature control during the oxidation process, and Due to a series of reasons such as the method being too old, the quality of the product is unstable, and there are defects in anti-aging, poor anti-oxidation ability, low elongation, and short life.

Abstract

The invention relates to a high-ductility polyethylene polypropylene fiber waterproof coiled material which is prepared by sequentially combining a first adhesive layer, a first rib reinforcement layer, a core layer, a second rib reinforcement layer and a second adhesive layer, wherein the core layer is a linear low density polyethylene layer modified by high-elasticity high-molecular compounds; the two surfaces are composed of a high-strength polypropylene fiber filament nonwoven fabric and an enhanced glass fiber fabric, so that the tensile breaking strength is enhanced to 170N / cm at the maximum; and the core layer is prepared by adding high-elasticity high-molecular compounds, an antiaging agent, a stabilizer, an adhesion promoter and the like into the linear low density polyethylene resin. By reasonably adding the high-elasticity high-molecular compounds, the coiled material has excellent ductility, and the maximum elongation at break is up to 1270%; and by adding the antiaging agent, the product has the characteristics of high aging resistance, high oxidation resistance, high corrosion resistance, favorable flexibility, high bending tendency, no breaking, high tensile resistance, high piercing resistance and the like. Therefore, the product is more suitable for waterproofing work in special positions.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a polyethylene polypropylene fiber waterproof coiled material with high elongation performance, which belongs to the field of construction engineering waterproof materials. Background technique [0002] At present, foreign new waterproof materials have accounted for more than 90% of the total market, and product quality, function, and service life have reached a relatively high level. Since the application of asphalt membranes in my country's waterproof projects in the 1970s, asphalt waterproof materials have always been the leading product for building waterproofing, accounting for about 70% of the total market recently, and polymer waterproof materials accounted for only about 10%. Others For waterproof coatings and other waterproof materials. From this point of view, the elastomer-modified asphalt waterproof membrane (SBS) technology produced in China is basically mature at this...
