SELF-SEALING WATERPOOFING SHEET HAVING SELF-SEALING PROPERTY AND APPARATUS FOR PRODUCING THE SAME

摘要

The present invention relates to an index member having a self-repairing function, a method for manufacturing the same, and an apparatus for manufacturing the same, to form a triple structure including a waterproof material layer formed by mixing sodium bentonite, which expands upon hydration, with an adhesive. After the polyester network is laminated, the step of laminating a waterproof material mixed with bentonite and adhesive thereon, the step of consolidating the release paper and the structure of the polyester network and the waterproof material to the desired density and thickness, and the consolidated release paper Forming a polyester network on top of the structure of the polyester network / waterproof layer, and cutting the structure of the release paper / polyester network / waterproof layer / polyester network to a desired width. To implement, a release paper supply unit; A polyester network supply unit; A bentonite mixture supply unit including a stirrer for stirring the adhesive and bentonite at a constant ratio, and an applicator for applying the same to the upper portion of the polyester network; A polyester net adhesive portion for adhesively forming a polyester net on the bentonite mixture; A cutting part including a cutting knife on the top to cut the product in a length direction to form a rod in a desired width; The manufacturing apparatus which consists of a release paper supply part, a belt conveyor which transfers the release paper and polyester network supplied from the polyester supply part to each working part is used. The water repellent material having the self-repairing function of the present invention manufactured by such a manufacturing method and a manufacturing apparatus is excellent in its waterproofing effect, extremely easy to install, its effect is permanent, and its function is not degraded even under high head pressure. have.
