Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing adhesion methods for perfluoroelastomer with metal components are inadequate, leading to limited use in applications like oil seals, rolls, and valves due to lack of suitable curing adhesives and increased manufacturing costs from multi-layer adhesive systems.
Innovation Solution
A curing adhesive composition comprising 50-400 parts by weight of a silane coupling agent and 50-400 parts by weight of an organometallic compound compounded with 100 parts by weight of a phenolic resin, specifically using poly-para vinylphenol resin, to create a single-layer adhesive for improved interlaminar adhesion of perfluoroelastomer laminated metals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a multi-layer adhesive system is used to bond perfluoroelastomer to metal, then adhesion performance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines multiple adhesive layers into a single integrated adhesive composition containing both silane coupling agents and organometallic compounds. This merging approach maintains the adhesion benefits of multi-layer systems while simplifying the manufacturing process to a single-layer application.
Solution Approach 2:
The invention creates a composite adhesive material that integrates the functional properties of different adhesive types (silane-based and organometallic-based) into one formulation. This composite approach allows the single layer to perform the functions that previously required separate layers.

Solution Approach 1:
The patent combines multiple adhesive layers into a single integrated adhesive composition containing both silane coupling agents and organometallic compounds. This merging approach maintains the adhesion benefits of multi-layer systems while simplifying the manufacturing process to a single-layer application.
3Temperature
If conventional fluororubber is used for sealing parts, then heat resistance and oil resistance are achieved, but chemical resistance to organic solvents deteriorates
Solution Approach 1:
The invention changes the chemical composition parameters of the adhesive system by incorporating organometallic compounds that are compatible with perfluoroelastomer, enabling the material to maintain its properties while achieving broader chemical resistance including resistance to organic solvents.

AI summary
To provide a curing adhesive composition that can be suitably used for bonding perfluoroelastomer and that is capable of improving the interlaminar adhesion between layers of a perfluoroelastomer laminated metal having a single adhesive layer. A curing adhesive composition obtained by compounding 50-400 parts by weight of a silane coupling agent and 50-400 parts by weight of an organometallic compound to 100 parts by weight of phenolic resin. This adhesive composition can be effectively used for the adhesion of a metal component and a perfluoroelastomer component. A perfluoroelastomer laminated metal using such an adhesive composition is, unlike conventional methods, capable of laminating a perfluoroelastomer component and a metal component using a single layer without forming multiple adhesive layers, and therefore said perfluoroelastomer laminated metal is capable of providing excellent effects including the ability to obtain conjugated sealing parts with excellent heat resistance and chemical (acid) resistance.
