Oil-Based Recording Liquid Clear Folder Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oil-based recording liquids face challenges in suppressing clear folder deformation during long-term storage due to high viscosity and polarity, leading to issues with ink ejection and adhesion, which results in short-term deformation suppression and inadequate storage properties.
Innovation Solution
The use of an oil-based recording liquid with a first organic medium having an SP value of 9.5 or more and an iodine value of 120 or more, or an allyl compound, which rapidly cures after recording, fixing the medium in the recording medium and preventing movement to the clear folder, along with the inclusion of metal soap or metal complex as oxidizing agents to promote oxidation polymerization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the viscosity of the recording liquid and the polarity of the medium are excessively high to suppress clear folder deformation, then the deformation of clear folder is suppressed for short term, but the ejection property of the recording liquid and adhesion between record materials deteriorate
Solution Approach 1:
The invention changes the chemical composition parameters of the oil-based medium by specifying precise SP value (9.0-10.5) and iodine value (100-150) ranges, and controlling content ratios between first and second organic media. This parameter optimization allows the medium to achieve both adequate viscosity for deformation suppression and appropriate ejection properties, resolving the contradiction between stability and operability.
2Stability of the object's composition
If the viscosity of the recording liquid and the polarity of the medium are excessively high to suppress clear folder deformation, then the deformation of clear folder is suppressed for short term, but the adhesion between record materials deteriorates
Solution Approach 1:
The invention optimizes the chemical parameters of the oil-based medium including SP value (9.0-10.5), iodine value (100-150), and the ratio of first to second organic medium content. These parameter changes enable the medium to provide sufficient viscosity for deformation suppression while maintaining adhesion strength through controlled polarity and composition.
3Object-affected harmful factors
If a low volatile organic compound is used as the medium to avoid health hazards, then health safety is improved, but the medium remains in and infiltrates into the recording medium causing strike through and bleeding
Solution Approach 1:
The invention changes the volatility and infiltration properties by selecting organic media with specific SP values (9.0-10.5) and iodine values (100-150). The first organic medium (50-95% content) provides low volatility for health safety, while the second organic medium (5-50% content) with lower SP value controls infiltration to prevent strike through and bleeding, thus resolving both harmful effects.
