The invention discloses a wide self-
adhesive high-
polymer composite waterproof coiled material and a production process thereof. The coiled material consists of three or four
layers, namely an isolating
membrane layer, a self-
adhesive layer, a waterproof plate layer or the isolating
membrane layer, the self-
adhesive layer, the waterproof plate layer and a
geotextile composite layer from top to bottom; the production process comprises the following steps of material preparation, mixing,
extrusion, rolling and compounding, storage, self-adhesive layer
coating, storage and coiling; the coiled material solves problems that the difficulty is high in the processes of production of the conventional
geotextile waterproof material and
engineering construction, the requirement on quality of constructors and the cost are high, the construction quality is not stable, the construction progress is slow, the conventional
geotextile waterproof material with a self-adhesive function is relatively narrow and inconvenient to construct, a large number of joints are generated because the geotextile waterproof material is frequently welded, the probability that quality problems occur after the geotextile waterproof material is welded is high, a product is compounded in the later period, and the production cost is high; the largest width of the waterproof coiled material reaches 3.05m; the self-adhesive function is realized; waterproof coiled material forming and self-adhesive layer
coating are performed on the same
production line, so that the production cost is reduced; and the waterproof coiled material is favorable for construction during waterproof
engineering such as tunnels, metros and culverts, and the construction quality is improved.
