Embodiment 1

[0070] A lapping method introduced by the content of the manual, the material is waterproof roll material 2 with double lapping sides, the lapping width of the long side is 70mm, and the first lapping side is HDPE base film + isolation film + self-adhesive film + Isolation film, the second lap is HDPE base film + isolation film + self-adhesive film + reactive sand layer.

[0071] During construction, the isolation film on each side is torn off, the HDPE base film + self-adhesive film on the first lap of the first waterproof membrane is exposed and separated, and the HDPE bottom of the second lap on the second waterproof coil is separated. The membrane is separated from the self-adhesive film + reactive sand layer, and the HDPE bottom film of the second lap of the second waterproof roll is lapped on the HDPE bottom film of the first lap of the first waterproof roll of another roll At the same time, use a hot air welding machine to heat the lapped edges, and after the coiled mat...

Embodiment 2

[0074] A lapping method introduced by the contents of the manual, the material is a waterproof membrane 2 with a single lapping edge, the material should be a single lapping edge, and the lapping width is 70mm.

[0075] During construction, put the non-lap edge reaction sand layer of the coil upward, and cover the exposed HDPE film surface of the other coil, heat the lap edge with a hot air welding machine, and compact it with a pressure roller after the coil is slightly melted; When the short side is lapped, use a special tool to shovel off the self-adhesive film layer and reactive sand layer on the surface of the coiled material that will be on the bottom surface, and then cover another coiled material on the exposed HDPE film surface, and heat it with a hot air welding machine For the overlapping edge, after the coil is slightly melted, compact it with a pressure roller, and fill the gap with a pressure-sensitive hot melt adhesive that is heated immediately on site. The over...

Abstract

The invention provides a waterproof coiled material pre-paving and inverted sticking process. A waterproof coiled material is paved under a basement bottom plate and on a cushion layer and comprises an HDPE bottom film, a self-adhesive glue film and a reaction sand anti-sticking layer. The reaction sand anti-sticking layer is arranged on the self-adhesive glue film. The HDPE bottom film is arranged under the self-adhesive glue film. The waterproof pre-paving construction technology comprises the following processes of a, basic layer examination and acceptance, b, working surface transfer, c, basic layer cleaning, d, joint enhancement treatment, e, snapline positioning; f, coiled material paving, g, coiled material lapping treatment, h, coiled material head unwinding and fixing, i, self-checking and acceptance and j, working surface transfer. According to the waterproof coiled material pre-paving and inverted sticking process, compared with a traditional waterproof method, the construction time and the maintenance time of a leveling layer and a protective layer are omitted, the structure level is optimized, so that the construction period is greatly shortened, and the construction cost is greatly reduced; and the effects of environmental protection and safety are achieved, solvent and fuel are not needed in the construction process, environmental pollution and firefighting hidden dangers are avoided, and energy sources are saved.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a CPC non-asphalt-based durable reactive high-density polyethylene self-adhesive film waterproof coiled material pre-paved anti-adhesive construction process. Background technique [0002] At present, asphalt-based waterproof materials and ordinary waterproof materials are difficult to meet the life requirements of buildings for waterproof materials. The main waterproof materials on the market are still dominated by asphalt-based waterproof materials, which have many disadvantages, such as serious water leakage, short life, and difficult construction. Not environmentally friendly. These problems urgently need reasonable solutions. Contents of the invention [0003] The invention proposes a CPC non-asphalt-based durable reaction type high-density polyethylene self-adhesive film waterproof roll material pre-paved anti-adhesive construction technology, which solves the probl...
