Composite Roofing Membrane Adhesive Water Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single ply roofing membranes often experience water migration between their layers due to their configuration, which can lead to inefficiencies and potential leaks in roofing systems.
Innovation Solution
A composite roofing membrane system is developed, comprising a roofing membrane, a roofing composite with a cap layer and reinforcing material, and an adhesive layer between them. The adhesive is a moisture-cure adhesive, specifically a silane-terminated polymer or polymethylmethacrylate, which enhances bonding and reduces water migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single ply roofing membrane configuration is used, then the roofing system is simple and easy to install, but water migration occurs between the layers
Solution Approach 1:
The patent applies composite materials by combining a roofing membrane with a roofing composite that includes a cap layer and reinforcing material, bonded together through an adhesive layer. This composite structure prevents water migration between layers while maintaining ease of installation through a modular assembly process.
2Reliability
If an adhesive layer is added between the roofing membrane and roofing composite, then water migration is prevented and bonding strength is improved, but the device complexity increases
Solution Approach 1:
The adhesive layer serves as an intermediary between the roofing membrane and roofing composite, creating a reliable bond that prevents water migration. The adhesive is specifically designed with moisture-curing properties and silane-terminated polymer or polymethylmethacrylate composition to ensure effective bonding without excessive complexity.
Solution Approach 2:
The adhesive layer's composition and curing characteristics are optimized to achieve effective bonding. The moisture-cure adhesive with silane-terminated polymer or polymethylmethacrylate undergoes chemical transformation when exposed to moisture, changing from a liquid or soft state to a cured bonded state, thereby achieving reliable waterproofing.
