COMBINING PROCESS OF COMPLETE SHEET

摘要

PURPOSE: A method for partially bonding joints of dual-composite waterproof sheets is provided to ensure high bonding stability by bonding the same materials and prevent defects by integrating a waterproof layer in an upper layer through double bonding. CONSTITUTION: A method for partially bonding joints of dual-composite waterproof sheets is as follows. A plurality of dual-composite waterproof sheets(10) are connected together. The dual-composite waterproof sheets comprise an upper layer(12) and a lower adhesive layer(14). The upper layer is mainly made of synthetic polymer. The lower adhesive layer is mainly made of rubberized asphalt and unvulcanized butyl rubber. At the state where the joints of the dual-composite waterproof sheets are overlapped, the upper layer of another dual-composite waterproof sheet is bonded on the top of the joints.
