DCP reaction sticky wet-laid waterproofing membrane polymer I. Introduction DCP reaction sticky wet-laid waterproofing membrane based on a polymer cross-laminated film and the reactive self-adhesive compound by a special process, high-performance, cold applied self stick waterproofing membrane, with excellent dimensional stability, thermal stability, UV resistance and bidirectional tear resistance. Seal system to achieve a comprehensive, safe and reliable. Second, product characteristics 1. Excellent self-adhesive and adhesion with the cement, construction in the wet base surface, a wide range of applications; full adhesion 2. building structure, effectively prevent liquid water and water vapor into the structure; 3. Good bonding properties, adhesive and web material joint life itself synchronization; 4. high tensile strength, elongation greater grass-roots stretching and cracking deformation applicability; 5. construction, steel and can be laid directly concrete without protective layer provided to accelerate the construction schedule. Implementation of standards DCP reaction sticky polymer wet-laid waterproofing membrane GB / T 23457-2009 "pre-shop / wet-laid waterproofing membrane" Three, Construction Method (1) the base surface trash, floating pulp and other clean. Base surface should be dried watering wet, but not have clear water. (2) according to waterproof specifications, to do detailed node 500 mm wide web site additional layer processing, and make the seal. (3) elastic line test shop. To play the first positioning line when playing the line, the distance between the second and the first for the width of the web, after the baseline between each reference line distance before a press aside not less than 80 mm ride then the width of the positioning. (4) In accordance with cement: water = 2: 1 weight ratio of cement paste formulation. First water is poured into the prepared raw mix slurry bucket, at high temperature, the base surface is dry, add the right amount of polymer plastic construction as insurance agent, and then cement into the water, soak for 15-20 minutes. After fully saturated, the excess water drained, with an electric mixer mixing not less than five minutes. (5) After the test shop, from one end of the coil lift, along the length of the fold, with the wallpaper knife in the fold at the lower surface film from the film roll gently cut open, be careful not to scratch the membrane; (6) The barrier film carefully torn from the web of self-adhesive surface, scratch cement paste. Scratch the surface of the base again, the membrane surface scratch again. Cement paste and base thickness depending on the level the case may be, the general thickness of 1.5 to 2.5 mm thick. Cement paste thickness should be uniform, smooth appearance. (7) The coil end painted cement paste lift back to the turn, paving on the grass, with the blade from the middle of the exhaust air to both sides scraping pressure, the scraping pressure discharge of cement paste back scraping edge. Coil other half were paving treated in the same manner. (8) Paving under a sheet, staggered 1/3 amplitude longitudinal length, roll up and down the length of two side lap Scratch cement paste with a wet-laid method, a width of not less than 80 mm. Lap before the insulating film at the edges of the upper and lower coil overlap removed. (9) Stones bilayer membrane, two floors and an adjacent two membrane seams should be staggered 1/3 ~ 1/2 width, and the two may not be mutually perpendicular paving the web. Before then the upper and lower coil surface paving the insulating film is removed, paving directly. Overlapping edge treatment: membrane overlapping edges of the long side torn insulation film directly dry adhesive side; the linesman take short coil length 1000 mm, width 160㎜ double-sided adhesive tape lap, lap width of not less than 80 mm. (10) received the first place be closed: the facade received the first coil end fixed or embedded in the top of the wall reserved for recess, and sealed with sealant. (11) After the waterproof layer laid out, and let sit for 24-48 hours, under normal circumstances, the higher the temperature, the shorter the time required. When hot weather waterproof layer exposure, use shade cloth covered.
