Embodiment 1

[0018] The first step, ingredients: the formula is polyvinyl chloride (PVC) or polyethylene (PE) + 5% moisture absorbing agent + 2.5% color masterbatch;

[0019] The second step, mixing: the main equipment is a screw, and the auxiliary equipment is a feeding device. Mix the ingredients evenly, enter the screw through the feeding device, and then fully melt and mix under the action of the high-temperature screw;

[0020] The third step, extrusion: the main equipment is a flat extrusion die, which evenly extrudes the plate-shaped molten material from the melted and mixed raw materials;

[0021] The fourth step, calendering and compounding: the main equipment is three calender rolls, the plate-shaped molten material enters the three calender rolls, and the plate-shaped molten material is calendered, cooled and formed to form a waterproof sheet;

[0022] The fifth step, storage: the equipment is an elastic storage rack, which buffers the slight asynchronous production speed of the...

Abstract

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.

Description

technical field [0001] The invention relates to a composite anti-seepage geosynthetic material and its production process, in particular to a wide-width self-adhesive polymer composite waterproof roll material and its production process used in waterproof projects such as tunnels, subways, and culverts. Background technique [0002] As we all know, with the development of transportation technology, the quality requirements and construction requirements of waterproof projects such as tunnels, subways, and culverts are rapidly increasing. The engineering design requires simple construction, good adhesion, wide width, and fast construction. The performance of existing special waterproof materials is gradually Can not meet the needs of engineering design. At present, waterproof boards commonly used in tunnels, subways, culverts and other projects are generally produced by polyethylene, and the width can be up to 6m. It is a commonly used waterproof material in projects. The exi...
