Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antifouling paints for marine structures have excellent antifouling effects but suffer from low surface smoothness, which affects their performance and durability.
Innovation Solution
A (meth)acrylic-modified silicone macromonomer is developed, which can be used to form a copolymer that provides both excellent antifouling properties and surface smoothness when used in antifouling paints, characterized by a specific chemical formula and synthesis methods that optimize the balance of siloxane and (meth)acrylic groups for improved coating properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antifouling paints comprising copolymer from siloxane-containing polymerizable monomer are used, then excellent antifouling effects are achieved, but surface smoothness is poor
Solution Approach 1:
The patent changes the chemical structure parameters of the polymer by introducing a macromonomer with a specific siloxane backbone structure and controlled molecular weight (parameter d: 1-1000 repeating units). This structural modification allows the polymer to achieve both excellent antifouling properties and improved surface smoothness in the coating
Solution Approach 2:
The patent creates a composite polymer structure combining siloxane-containing macromonomer units with (meth)acrylic polymer chains. This composite structure integrates the hydrophobicity and antifouling characteristics of siloxane with the coating-forming ability of (meth)acrylic polymers, achieving both smooth surface and effective antifouling performance
