Abstract

The invention belongs to the technical field of waterproof coiled material construction, and discloses a fluorescent hot-melt gasket as well as a preparation method and application thereof. The fluorescent hot-melt gasket is a fluorescent blending hot-melt gasket or a fluorescent interlayer hot-melt gasket; the fluorescent hot-melt gasket is prepared from the following components: polyolefin resin, an antioxidant, stearic acid amide and fluorescent master batch; and the fluorescent master batch comprises the following components: polyolefin resin, heavy calcium carbonate, a fluorescent agent and a coupling agent. Compared with a traditional hot-melt gasket, the fluorescent hot-melt gasket has the advantages that the welding speed can be remarkably increased, and the welding accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material construction, and in particular relates to a fluorescent hot-melt gasket and its preparation method and application. Background technique [0002] In the waterproof construction process of composite concrete lining structures such as tunnels, tunnels, and subway tunnels, hot-melt gaskets are usually used for temporary laying and hanging of waterproof membranes. At present, the common welding methods of hot-melt gaskets are electromagnetic welding and hot air welding. Among them, the hot-melt gasket for electromagnetic welding can be welded with an electromagnetic gun through the membrane after the waterproof membrane is laid and hung as a whole. [0003] Due to the lack of light in the tunnel and the dark environment where lighting is inconvenient, the position of the hot-melt gasket cannot be found in a timely and convenient manner during the construction process of the waterpr...
