Solution Overview
Problem
Conventional fire-retardant coating systems lack broad adhesion, solvent resistance, and antimicrobial properties, and often contain hazardous materials like antimony and halogens, which pose health and environmental risks.
Innovation Solution
A multi-faceted coating system comprising urethane resins, monofunctional and multifunctional monomers, a reactive diluent, intumescent fire-retardant additives, and silver-based antimicrobial agents, which provides excellent fire-retardancy, adhesion, solvent resistance, and antimicrobial activity while avoiding hazardous halogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional fire-retardant coating systems are used, then fire-retardant properties are provided, but adhesion to substrates deteriorates
Solution Approach 1:
The patent employs a composite coating formulation combining acrylic polymer, vinyl acetate monomer, fire-retardant additives (ammonium polyphosphate, melamine cyanurate), and titanium dioxide. This composite approach integrates multiple functional components that work synergistically to achieve both fire-retardant protection and substrate adhesion, resolving the contradiction between fire safety and bonding reliability.
2Object-affected harmful factors
If conventional fire-retardant coating systems are used, then fire-retardant properties are provided, but solvent resistance deteriorates
Solution Approach 1:
The coating system uses a composite formulation with crosslinking agents (glycerol, pentaerythritol) that create a chemically resistant network structure. This composite material approach enables the coating to maintain both fire-retardant functionality and resistance to solvents like acetone and alcohol, preventing degradation during routine cleaning.
3Object-affected harmful factors
If antimony and halogens are used in fire-retardant coatings, then fire-retardant properties are enhanced, but health and environmental hazards increase
Solution Approach 1:
The patent explicitly removes hazardous antimony and halogen compounds from the coating formulation. Instead, it uses safer alternatives: ammonium polyphosphate and melamine cyanurate as fire-retardant additives. This extraction of harmful substances while maintaining fire-protection functionality directly addresses the contradiction between effectiveness and safety.
Solution Approach 2:
The patent converts potentially harmful substances into beneficial ones by replacing toxic antimony and halogens with environmentally friendly phosphorus-nitrogen based fire-retardant additives. These alternatives provide equivalent or superior fire protection without the health and environmental hazards, turning a harmful formulation approach into a safe one.
4Object-affected harmful factors
If conventional fire-retardant coatings are applied, then fire safety is improved, but antimicrobial protection is lost
Solution Approach 1:
The patent merges two distinct protective functions into a single coating system: fire-retardant protection (via ammonium polyphosphate and melamine cyanurate) and antimicrobial protection (via zinc oxide and silver sulfate). This combined formulation resolves the contradiction by providing both fire safety and hygiene protection simultaneously, eliminating the need for separate coatings.
