Fixing Member Resin Suppresses Foreign Substance Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing members face issues with foreign substances adhering to their surfaces, leading to damage and unintended separation due to lateral displacement in a joined state, which is not effectively addressed by increasing adhesiveness to prevent such displacement.
Innovation Solution
A fixing member formed from a cured product of a resin composition containing a resin, a curing agent, and a silicone-based surface modifier, with specific content ranges for the curing agent and silicone-based surface modifier, which reduces foreign substance adhesion and suppresses separation due to lateral displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adhesiveness between fixing members is increased to prevent lateral displacement, then the reliability of the joined state is improved, but foreign substances tend to adhere to the surfaces of the fixing members
Solution Approach 1:
The invention changes the chemical composition parameters of the resin by controlling the curing agent content (3-20 parts by mass per 100 parts by mass of resin) and silicone-based surface modifier content (0.01-5 parts by mass per 100 parts by mass of resin). This parameter optimization achieves a balance where the resin has sufficient adhesiveness to prevent lateral displacement while the surface properties are modified to reduce foreign substance adhesion.
Solution Approach 2:
The invention uses a composite resin material comprising multiple components: base resin, curing agent, and silicone-based surface modifier. This composite structure allows the bulk material to maintain high adhesiveness for preventing lateral displacement, while the silicone-based surface modifier creates a low-energy surface that resists foreign substance adhesion, thus resolving the contradiction between these two requirements.
2Strength
If the adhesiveness between fixing members is increased to suppress separation, then the strength of the joined state is improved, but the manufacturing precision is worsened due to foreign substance adhesion
Solution Approach 1:
By optimizing the curing agent content within 3-20 parts by mass per 100 parts by mass of resin, the invention achieves sufficient crosslinking density to provide strong bonding strength that suppresses separation, while avoiding excessive adhesiveness that would cause foreign substance adhesion and appearance defects.
Solution Approach 2:
The composite resin system with controlled proportions of base resin, curing agent, and silicone-based surface modifier creates a material that simultaneously provides high bonding strength for separation suppression and a clean surface appearance by reducing foreign substance adhesion through surface modification.
