Solution Overview
Problem
There is a demand for improving the antifouling properties and durability of hydrophilicity on inorganic substrates, such as crockery, to enhance cleaning efficiency and prevent mineral deposits.
Innovation Solution
A surface treatment agent comprising a pretreatment agent with a silane compound and a polyfunctional monomer, and a hydrophilizing treatment agent, where the polyfunctional monomer has reactive groups that react with both the silane compound and the hydrophilizing agent, forming crosslinking points to improve hydrophilicity and antifouling properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a silane coupling agent and hydrophilic compound are applied sequentially (conventional method), then hydrophilicity is improved, but durability and antifouling property are insufficient
Solution Approach 1:
The patent introduces a polyfunctional monomer as an intermediary between the silane coupling agent and hydrophilic compound. This monomer has multiple reactive groups that enable it to bridge both components, forming a more stable and durable surface treatment layer with enhanced antifouling properties
Solution Approach 2:
The invention creates a composite surface treatment structure consisting of silane coupling agent, polyfunctional monomer, and hydrophilic compound working together. This composite approach combines the adhesion benefits of silane with the hydrophilicity of the compound, mediated by the polyfunctional monomer, to achieve superior durability and antifouling performance
2Reliability
If conventional surface treatment is applied to inorganic substrates, then hydrophilicity is improved, but antifouling property is insufficient
Solution Approach 1:
The polyfunctional monomer serves as a mediator that simultaneously reacts with the silane coupling agent and hydrophilic compound, creating a integrated surface treatment system that provides both hydrophilicity and antifouling properties in a single application process
Solution Approach 2:
The polyfunctional monomer performs multiple functions: it acts as a bridge between silane and hydrophilic compound, provides additional crosslinking points for enhanced durability, and contributes to antifouling properties. This multi-functionality simplifies the overall treatment process while achieving multiple performance goals
