Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acrylic resin compositions lack sufficient chemical resistance and oil resistance, leading to damage and shortened lifespan of electronic devices and industrial adhesives when exposed to chemicals and oils.
Innovation Solution
An acrylic resin composition with a polymer unit derived from a specific monomer formula (1), where the monomer unit constitutes 40 to 99% of the polymer, enhancing the resin's tensile strength and polarity to resist oleic acid and other chemicals and oils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If general acrylic resin is used as adhesive material, then good flexibility and stress followability are achieved, but chemical resistance and oil resistance deteriorate
Solution Approach 1:
The patent changes the chemical composition parameters of the acrylic resin by incorporating specific monomer units (carboxylic acid-containing units and hydroxyl group-containing units) in controlled proportions. This compositional parameter change enables the resin to achieve both flexibility and chemical/oil resistance simultaneously, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent creates a composite acrylic resin system by combining multiple functional monomer units within the same polymer structure. The resin contains carboxylic acid-containing units, hydroxyl group-containing units, and other acrylic monomer units in specific proportions, forming a composite material that exhibits both flexibility and resistance to chemicals and oils.
2Ease of operation
If acrylic foam base material is used in double-sided adhesive tape, then excellent flexibility is achieved, but durability in chemical environments deteriorates
Solution Approach 1:
The patent modifies the chemical composition parameters of the acrylic foam base material by incorporating carboxylic acid-containing monomer units and hydroxyl group-containing monomer units in specific proportions. This parameter change enables the foam to maintain flexibility while achieving durability in chemical environments, including resistance to detergents, waxes, and other chemicals.
3Reliability
If conventional acrylic resin is used in adhesive applications, then good adhesion is achieved, but lifespan in oil environments deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters of the acrylic resin by incorporating hydroxyl group-containing monomer units and carboxylic acid-containing monomer units in specific proportions. This parameter change enables the resin to maintain good adhesion performance while achieving extended lifespan in oil environments by resisting dissolution and degradation from oil exposure.
