Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tackifier resin emulsions used in pressure-sensitive adhesives do not provide sufficient pressure-sensitive adhesive force and curved surface adhesiveness.
Innovation Solution
A tackifier resin is developed as a reaction product of rosins, a ring structure-containing compound, and an alcohol, specifically incorporating compounds with alicyclic and aromatic groups to enhance adhesive properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional tackifier resin emulsion is mixed with a pressure-sensitive adhesive, then the adhesive composition is formed, but the pressure-sensitive adhesive force and curved surface adhesiveness are insufficient
Solution Approach 1:
The patent changes the chemical structure parameters of the tackifier resin by incorporating specific ring structure-containing compounds (compounds having an isobornyl group, compounds having a benzyl group, or compounds having an alicyclic group containing two or more alicyclic rings) into the reaction product of rosins and alcohols. This structural modification optimizes the molecular weight distribution and chemical composition to achieve both high pressure-sensitive adhesive force and excellent curved surface adhesiveness
Solution Approach 2:
The patent creates a composite tackifier resin by combining multiple components: rosins (A), ring structure-containing compounds (B) capable of reacting with the rosins, and alcohols (C). This composite structure integrates the adhesive properties of rosins with the structural benefits of ring-containing compounds to simultaneously improve pressure-sensitive adhesive force and curved surface adhesiveness
