Since 2016, China has popularized fabricated buildings in all aspects, and the fabricated buildings are planned to account for more than 50% of new buildings in 2025 years, the fabricated buildings become a new trend of future buildings. Fabricated buildings require a large number of precast concrete composite slabs which require form-molding when precast. In the prefabrication process of the laminated slab template forming, the sealing strip has the function of being adhered to the template, and concrete slurry is prevented from flowing from a gap of the mold, so that the contour of the laminated slab is uneven, and the use is not influenced. It follows that the sealing effect of the formwork during factory prefabrication is crucial to the production quality of the laminate.
Besides pouring concrete slurry, a plurality of steel bars are needed to be added as framework materials to increase the strength of the composite slab during the prefabrication production of the composite slab, and the steel bars need to be manually moved to adjust positions during the prefabrication forming with the concrete slurry. In the shifting and adjusting process, the surface of the steel bar is provided with threads, so that the friction force between the steel bar and the sealing strip is large, the structure of the sealing strip is damaged frequently, the sealing effect of the sealing strip is lost, and the flatness of the outline of the produced laminated slab is influenced. To solve this problem, the method adopted at present is usually to replace the sealing strip when the sealing strip is worn to a certain extent so as to ensure the sealing effect on the formwork.
The existing sealing strip is usually a solid strip-shaped sealing strip, and is fixed on a template in a double-sided adhesive tape or glue brushing mode when in use. The sealing strip has poor elastic strain performance, high probability of being worn, long service life generally not more than 3 times, high replacement frequency and large replacement amount, causes a large amount of waste and simultaneously reduces the production efficiency of the laminated slab; and it uses double faced adhesive tape or glue to install fixedly, and not only clearance difficulty when changing lets change complex operation, influences production efficiency, and the installation location is unstable, very easily drops, influences sealed effect, causes harmful effects to the production quality of superimposed sheet. For this reason, it is necessary to develop a sealing tape having high elastic strain, good positioning ability and high sealability for use in the production process of fabricated building laminates.
