Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PVC tile floor coating methods suffer from low abrasion resistance, chemical resistance, heat resistance, and weatherability, leading to frequent detachment, maintenance costs, and poor durability due to low cross-linking density and adhesion issues.
Innovation Solution
A multilayer coating method involving a foundation step of cleaning and a glazing step with a gas glazer using a wax layer and a coating agent, applying a coating agent with a cotton or white pad at specific rpm and heat, forming a protective film that prevents scratches, stains, and detachment, while improving gloss and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If photocuring coating agent is applied to improve surface properties, then abrasion resistance and chemical resistance are improved, but heat resistance deteriorates and films are damaged upon exposure to momentary heat
Solution Approach 1:
The coating system is divided into multiple functional layers: a base coat layer providing abrasion and chemical resistance, and a clear topcoat layer providing heat resistance and gloss. This segmentation allows each layer to optimize its specific function without compromising the others.
Solution Approach 2:
The invention uses a composite coating structure combining different resin systems - the base coat uses a photocuring composition with urethane acrylate for durability, while the topcoat uses a heat-resistant formulation. This composite approach enables simultaneous achievement of abrasion resistance and heat resistance.
2Temperature
If cross-linking density is increased to improve heat resistance, then heat resistance is improved, but adhesion strength is lowered and cracks occur
Solution Approach 1:
The coating is segmented into two layers with different cross-linking densities - the base coat has moderate cross-linking for flexibility and adhesion, while the topcoat has higher cross-linking for heat resistance. This prevents crack propagation through the entire coating system.
Solution Approach 2:
Different regions of the coating have different properties: the base coat is formulated for flexibility and adhesion to the substrate, while the topcoat is formulated for heat resistance and surface quality. This local optimization resolves the contradiction between heat resistance and adhesion.
3Stability of the object's composition
If conventional detergent is used for detachment to maintain floor appearance, then appearance is maintained, but toxic chemical substances cause environmental pollution and respiratory diseases
Solution Approach 1:
The coating is designed as a sacrificial protective layer that can be easily removed and reapplied without harsh chemicals. Instead of using toxic detergents for detachment, the entire coating system is replaced periodically, eliminating exposure to harmful substances while maintaining appearance.
Solution Approach 2:
The coating formulation includes additives that reduce surface energy and improve release properties, allowing for easier detachment with minimal chemical intervention. This parameter change enables maintenance of appearance without reliance on toxic detergents.
4Strength
If multilayer coating structure is formed to improve durability and protection, then abrasion resistance and fouling resistance are improved, but coating process complexity increases
Solution Approach 1:
The base coat and topcoat are applied in sequence using the same photocuring equipment and methodology. The process merges the benefits of two layers while using a unified application and curing system, minimizing the increase in process complexity.
Solution Approach 2:
The coating system is designed so that a single photocuring coating agent formulation can serve multiple functions - providing both the protective base layer and the aesthetic top layer, or enabling sequential application of complementary layers. This universality reduces the need for specialized equipment for each layer.

AI summary
Provided is a method of coating a PVC tile floor with improved fouling resistance, abrasion resistance, workability and gloss. The method includes forming wax coating having a plurality of layers (a multilayer structure) on the surface of PVC tiles, and coating the uppermost surface of a wax layer with a coating agent for polishing stone surfaces so that a protective coating film for primarily protecting the floor from the outside is formed unlike a conventional floor coating having a pure wax layer structure, thereby advantageously fundamentally preventing scratches and stains of the surface, avoiding detachment and sliding of films and greatly improving durability and safety in use, and, in spite of simplified coating process, preventing yellowing, securing superior gloss, and improving workability and processability as well as maintenance/conservation after working and economic efficiency.
