However, there are still some bottlenecks in the application of this material. During construction, the short sides of the coil are not easy to overlap. In this way, waterproof weak points are formed at the overlapping parts of the short sides, which greatly reduces the waterproof effect.

The invention belongs to the technical field of waterproof rolls and particularly relates to a short-edge lap joint process for non-asphalt-base waterproof rolls. The process comprises the steps of during short edge lap joint, cutting a non-asphalt-base pressure-sensitive adhesive tape, and removing a lower isolation membrane on the non-asphalt-base pressure-sensitive adhesive tape; laying the face of the non-asphalt-base pressure-sensitive adhesive tape with the lower isolation membrane removed on the rough surface of the upper portion of a polymer sheet at the short edge lamp joint position flatly; removing the isolation membrane on the non-asphalt-base pressure-sensitive adhesive tape, heating the non-asphalt-base pressure-sensitive adhesive tape to a molten state through a hot air fan, melting the molten adhesive tape into the rough surface of the polymer sheet, and putting the short edge lap joint position of another polymer sheet flatly on the non-asphalt-base pressure-sensitive adhesive tape; performing compression with a roller to complete lap joint. According to the short-edge lap joint process, complexity and unreliability of prior processes are avoided, the site construction is free of open fire, safe and environment-friendly standards are achieved, the site operation is flexible and convenient, and the lap joint is reliable.
Description
technical field [0001] The utility invention belongs to the technical field of waterproof coiled material construction, in particular to a non-asphalt-based waterproof coiled material short-side overlapping construction process. Background technique [0002] The polymer non-asphalt-based sand surface membrane has excellent waterproof performance, can be integrated with the subsequent pouring concrete, and is still inseparable under long-term immersion. It has outstanding properties such as tensile resistance, puncture resistance, and ultraviolet radiation resistance. The waterproof membrane has poor resistance to ultraviolet radiation and is easy to puncture. It is gradually accepted by the majority of customers and has developed rapidly, breaking the traditional concept of waterproofing and realizing the "skin" waterproofing of buildings. However, there are still some bottlenecks in the application of this material. During construction, the short sides of the coil are not ...
