Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alcohol-based inks require a large amount of adhesive components to achieve adhesion comparable to solvent-based inks, leading to increased viscosity and decreased dispersibility and stability, making them impractical for use.
Innovation Solution
A dispersion composition comprising a modified polyolefin resin dispersed in an alcohol and aliphatic hydrocarbon solvent mixture, with specific (meth)acrylic acid components, achieving high solid content and low viscosity while maintaining good stability and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large amount of adhesive component is added to achieve good adhesion, then adhesion is improved, but viscosity increases and dispersibility decreases
Solution Approach 1:
The patent changes the chemical structure parameters of the adhesive component by introducing specific functional groups (carboxyl, hydroxyl, or amine groups) into the polyolefin resin. This structural modification enables the resin to achieve good adhesion at lower concentrations, thereby avoiding the viscosity increase and dispersibility deterioration that occur when large amounts of conventional adhesive are added.
Solution Approach 2:
The patent creates a composite adhesive system by combining polyolefin resin with specific functional additives or modifiers that introduce polar groups. This composite structure allows the material to achieve both good adhesion and low viscosity, resolving the contradiction between bonding strength and ease of dispersion.
2Strength
If a large amount of adhesive component is added to achieve good adhesion, then adhesion is improved, but sustainable stability decreases
Solution Approach 1:
The patent modifies the chemical parameters of the adhesive component by incorporating functional groups (carboxyl, hydroxyl, or amine groups) into the polyolefin resin structure. This modification enables the resin to maintain sustainable stability while achieving good adhesion, eliminating the need to add large amounts of adhesive that would compromise long-term stability.
3Strength
If a large amount of adhesive component is added to achieve good adhesion, then adhesion is improved, but viscosity increases
Solution Approach 1:
The patent changes the molecular structure parameters of the adhesive component by introducing functional groups (carboxyl, hydroxyl, or amine groups) into the polyolefin resin. This structural change allows the resin to achieve good adhesion at lower concentrations, thereby preventing the viscosity increase that occurs when large amounts of conventional adhesive are added.
4Strength
If solid content is increased to improve adhesion, then adhesion is improved, but dispersibility decreases
Solution Approach 1:
The patent changes the chemical composition parameters of the adhesive component by incorporating functional groups (carboxyl, hydroxyl, or amine groups) into the polyolefin resin structure. This modification enables the resin to maintain good dispersibility even at high solid contents, resolving the contradiction between adhesion strength and ease of dispersion.
