Removable Tile Floor System Using Dispersion Polymer Adhesive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic or stone tile floor coverings are difficult to remove without causing damage, requiring significant mechanical force and resulting in the destruction of tiles and the need for extensive preparation before reapplication.
Innovation Solution
A tile-based floor covering system using a polyacrylate dispersion polymer as the first adhesive layer between the substrate and a decoupling mat, with a mortar-based tile adhesive layer for the tiles, allowing for easy dismantling by pulling off the decoupling mat, leaving a clean surface ready for new flooring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mortar-based adhesive is used to attach tiles to the substrate, then the floor covering achieves high mechanical resistance and durability, but the tiles and substrate become difficult to separate requiring significant mechanical force and causing damage
Solution Approach 1:
The adhesive system is segmented into two distinct layers: a lower dispersion polymer-based adhesive layer providing reversible bonding to the substrate, and an upper mortar-based tile adhesive layer providing strong mechanical bonding to the tiles. This segmentation allows the lower layer to enable easy removal while the upper layer ensures mechanical strength.
Solution Approach 2:
The decoupling mat serves as an intermediary layer between the substrate and the tile layer. It is adhered to the substrate by the dispersion polymer-based adhesive and provides a interface that allows for easy peeling off of the entire tile assembly, while still transmitting sufficient load during normal use.
2Reliability
If traditional tile adhesive is used, then the floor covering remains stable during use, but removal requires complete destruction of tiles and extensive substrate preparation
Solution Approach 1:
The chemical parameters of the adhesive system are changed by using a dispersion polymer-based adhesive with specific properties (aqueous dispersion, flexible polymer chain) in the lower layer. This allows the adhesive to maintain bond strength during normal use but become removable under controlled conditions, enabling tile removal without substrate damage.
Solution Approach 2:
The adhesive system is a composite of two different adhesive types: dispersion polymer-based adhesive (lower layer) and mortar-based tile adhesive (upper layer). Each layer contributes different properties - the lower layer provides reversible bonding for easy removal, while the upper layer ensures stable attachment during use.
3Reliability
If flexible fiber-based uncoupling layers are used, then sound propagation is interrupted and cracks are suppressed, but the floor covering remains difficult to remove without damage
Solution Approach 1:
The invention uses a decoupling mat that copies the function of traditional fiber-based uncoupling layers (crack suppression and sound isolation) but with a critical modification: it is combined with a dispersion polymer-based adhesive that enables easy removal. The mat itself may be fiber-based but the adhesive system transforms its removability characteristics.
