Problems solved by technology

In addition, during construction, the bonding strength between the asphalt-based waterproofing membrane and the concrete structure is affected by factors such as the quality of the base layer, the construction environment, and the skill of the construction technicians. It cannot be guaranteed that each construction will meet the requirements of the construction technical specifications. The construction site often has problems such as poor bonding between the coiled material and the base layer, drumming, water channeling, and leakage, and increases the construction cost; in addition, ordinary coiled material construction requires many procedures and takes a long time to construct

Description

technical field [0001] The invention relates to a polymer self-adhesive film coil material with SEBS self-adhesive as a self-adhesive layer and a production method thereof, belonging to the field of building waterproof materials. Background technique [0002] At present, for large-scale building waterproof construction, waterproof membrane has become the material of choice. Traditional asphalt-based waterproofing membranes or modified asphalt waterproofing membranes are usually constructed using the hot-melt method, but this construction method is easily affected by environmental factors and cannot be constructed in wet or rainy weather; at the same time, the hot-melt method uses open flame construction, which has Security risks. Nowadays, many big cities have banned the use of open flames in construction, which puts forward higher requirements for manufacturers of waterproof membranes. In addition, during construction, the bonding strength between the asphalt-based waterp...
