Primer Layer for Acrylic Rubber Silicone Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current release layers in electrostatic image transfer systems have issues with adhesion, slow curing, short pot life, and low mechanical strength, leading to adhesion problems and inhibition of addition cure RTV silicone layers when directly applied over acrylic rubber layers.
Innovation Solution
An intermediate transfer member with a primer layer composed of epoxyalkylalkoxysilane, alkenylsilane, polyorganohydrosiloxane, and a titanium catalyst is used between the acrylic rubber layer and the addition cure RTV silicone layer, preventing poisoning and enhancing anchorage, thereby improving adhesion and mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a release layer is directly applied over an acrylic rubber layer, then adhesion is improved, but the addition cure RTV silicone layer is poisoned and curing is inhibited
Solution Approach 1:
A primer layer is introduced as an intermediary between the acrylic rubber layer and the addition cure RTV silicone release layer. This primer layer prevents the acrylic rubber from poisoning the silicone curing process while maintaining strong adhesion to both layers, thus resolving the contradiction between adhesion and curing reliability.
Solution Approach 2:
The release layer structure is segmented into multiple functional layers: the acrylic rubber layer provides mechanical strength and adhesion, the primer layer prevents chemical interference, and the addition cure RTV silicone layer provides release properties. This segmentation allows each layer to perform its specific function without interfering with others.
2Ease of manufacture
If current release layer formulations are used, then release properties are achieved, but curing time is long and mechanical strength is low
Solution Approach 1:
The patent changes the chemical composition parameters of the release layer by using addition cure RTV silicone material instead of conventional formulations. This parameter change results in faster curing times and improved mechanical strength while maintaining the necessary release properties for electrostatic image transfer.
