Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reactive resins struggle to cure in thin layers at room temperature, leading to issues with durability, abrasion resistance, and yellow discoloration, while current solutions either require additional energy or result in shorter service lives and environmental concerns.
Innovation Solution
A novel (meth)acrylate-based reactive resin with a four-component hardener system, including permaleinates, zinc salts, sulfur compounds, and phosphorus compounds, which accelerates curing at room temperature and prevents yellowing, allowing for thin-layer applications with improved durability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If reaction resins are used in thin layers, then the heat of reaction is insufficient for complete curing, but using additional energy (light or radiation) is not practical for many applications
Solution Approach 1:
The invention changes the chemical parameters of the curing system by introducing a multi-component hardener system with permaleinates, zinc salts, sulfur compounds, and phosphorus compounds. This chemical modification enables the resin to cure exothermically in thin layers without requiring external energy input, resolving the contradiction between thin layer application and complete curing.
2Speed
If amine-containing systems are used to accelerate curing, then curing speed improves, but yellow discoloration occurs
Solution Approach 1:
The invention replaces amine-based accelerators with a novel hardener system based on permaleinates combined with zinc salts, sulfur compounds, and phosphorus compounds. This chemical substitution maintains fast curing speed while eliminating the yellow discoloration problem associated with amine-containing systems.
3Volume of moving object
If solvent- or water-based thermoplastic paints are used for thin-layer systems, then application in thin layers is possible, but service life is significantly shorter due to higher abrasion
Solution Approach 1:
The invention uses a composite chemical system combining permaleinates, zinc salts, sulfur compounds, and phosphorus compounds in a reactive resin matrix. This composite approach enables the material to achieve both thin-layer applicability and high durability through crosslinking, resolving the contradiction between thin layer thickness and long service life.
4Reliability
If chlorinated dibenzoyl peroxide and dibenzoyl peroxide are used as initiators, then curing can be achieved, but toxicologically questionable halogen-organic degradation products are released
Solution Approach 1:
The invention extracts and removes the harmful chlorine-containing components from the initiator system. By replacing chlorinated dibenzoyl peroxide and dibenzoyl peroxide with a chlorine-free hardener system based on permaleinates and metal complexes, the invention maintains curing capability while eliminating the release of toxic halogen-organic degradation products.
