Biodegradable Three-Layer Coating for Ceramic Imitation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paint coatings are difficult to decompose and cause environmental pollution, and they fail to achieve a realistic imitation ceramic effect with their limited properties of anticorrosion, waterproofing, and chemical resistance.
Innovation Solution
A three-layer paint coating system comprising a primer layer, a middle layer, and a surface layer, specifically formulated with ingredients like thermosetting acrylic resin, water-based or oil-based imitation porcelain coatings, and polyurethane (PU) imitation porcelain surface coatings, which can be applied to various materials to mimic ceramic appearance and properties without high-temperature processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paint coating materials are used, then anticorrosion and waterproof properties are achieved, but the materials are difficult to decompose and cause environmental pollution
Solution Approach 1:
The patent changes the chemical composition parameters of the paint coating material by using water-based acrylic resin instead of traditional organic solvents, making the material biodegradable while maintaining protective properties. The specific formulation includes water-based acrylic resin (40-60 parts), titanium dioxide (10-20 parts), and other additives in controlled proportions to achieve both durability and environmental friendliness
Solution Approach 2:
The patent creates a composite paint coating material combining water-based acrylic resin with inorganic pigments (titanium dioxide, zinc oxide), fillers (calcium carbonate, talcum powder), and biodegradable additives. This composite structure provides both the protective function and environmental decomposability
2Reliability
If regular paint coating materials are used, then basic protective properties are achieved, but a truly imitation ceramic effect is not achieved
Solution Approach 1:
The patent applies different functional components to specific aspects of the coating: titanium dioxide and zinc oxide for ceramic-like whiteness and opacity, calcium carbonate and talcum powder for matte ceramic texture, and the water-based acrylic resin system for glaze-like finish. Each ingredient serves a specific local quality requirement to achieve the overall ceramic effect
Solution Approach 2:
The patent adds dimensional complexity to the coating by incorporating multiple layers with different functions: a base layer for adhesion, a pigment layer for ceramic color and opacity, a filler layer for texture, and a top layer for glaze finish. This multi-dimensional structure creates the realistic ceramic appearance that single-layer paints cannot achieve

AI summary
A coating material with a primer layer, a middle layer and a surface layer and its method of application which includes the steps: (1) spraying the primer layer material onto an article; (2) spraying or brushing the middle layer material with a first color until satisfactorily coated; (3) repeating step (2) with the middle layer material having a second color and allowing drying; and (4) spraying the surface layer material of PU imitation porcelain material and allow drying to obtain the article with superior imitation ceramic effect. The present invention can be applied to any plastic and poly articles with a contoured body, making a highly imitative ceramic article such as pot or vase to replacing the existing authentic ceramic articles. Since the material being used is biodegradable, therefore effectively decreasing the level of pollution and damages to the environment and hence lessening the health hazards to human.
