Solution Overview
Problem
Existing ceiling systems face challenges with decorative coatings that have unpredictable pot-life and manufacturing time, leading to difficulties in application and drying, which affect both manufacturing efficiency and aesthetic appeal.
Innovation Solution
A coated building panel with a surface coating comprising inorganic pigment and a humectant containing a first ester-containing compound, where the liquid carrier is present in an amount less than 1 wt.% or ranging from 10 wt.% to 30 wt.% based on the total weight of the coating, providing improved carrier retention and viscosity stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If decorative coatings are applied to building panels to enhance aesthetic properties, then aesthetic appeal is improved, but manufacturing time and pot-life unpredictability increase
Solution Approach 1:
The patent changes the chemical parameters of the coating formulation by incorporating specific esters (such as ethyl lactate, propyl lactate, or glycol esters) as humectants and viscosity modifiers. These parameter changes enable the coating to maintain stable viscosity and predictable pot-life, resolving the contradiction between aesthetic quality and manufacturing time efficiency
Solution Approach 2:
The patent creates a composite coating material that combines inorganic pigments, binders, and specifically selected ester-based humectants. This composite formulation achieves both aesthetic properties through proper pigment dispersion and manufacturing efficiency through controlled viscosity and extended pot-life, directly addressing the technical contradiction
2Loss of substance
If high solids content coating is used to reduce carrier loss, then carrier retention is improved, but viscosity stability deteriorates
Solution Approach 1:
The patent introduces ester-based humectants (ethyl lactate, propyl lactate, glycol esters) as intermediary substances that mediate between the high solids content requirement and viscosity stability. These intermediaries provide carrier retention through their humectant properties while simultaneously acting as viscosity modifiers to maintain composition stability, resolving the contradiction between reduced carrier loss and viscosity stability
