Composite Wax Coating Agent for Clay Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agents/primers fail to ensure sufficient adhesion between a porous basic frame and industrial clay, particularly in semi-automatic and fully automatic application processes, leading to reduced bonding and contamination issues.
Innovation Solution
A coating agent comprising a base wax portion with a melting range below 80°C and a synthetic wax portion with a higher melting point, combined with optional additives like rheological additives, tackifiers, and colorants, is applied to the basic frame, allowing for increased adhesion when heated by the industrial clay, forming a strong bond without a lubricant film.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional agents/primers are used to improve adhesion between basic frame and industrial clay, then adhesion is enhanced, but they fail to provide sufficient adhesion in semi-automatic and fully automatic application processes
Solution Approach 1:
The patent changes the chemical composition parameters of the coating agent by combining silane-based primers with specific wax components (paraffin wax, microcrystalline wax, and/or polyalphaolefin wax) in defined ratios. This parameter modification enables the coating to provide sufficient adhesion in automated application processes where conventional primers fail, resolving the contradiction between adhesion strength and automation compatibility
Solution Approach 2:
The patent creates a composite coating agent by combining silane-based primer components with wax components (paraffin wax, microcrystalline wax, and/or polyalphaolefin wax) in specific weight ratios (20-70% silane, 30-80% wax). This composite formulation synergistically provides both strong adhesion properties and compatibility with automated application processes, resolving the technical contradiction between adhesion strength and automation extent
2Ease of operation
If semi-automatic application system is used to apply clay, then application process is simplified, but adhesion between clay and basic frame is significantly reduced
Solution Approach 1:
The patent modifies the coating agent composition by incorporating specific wax components (paraffin wax, microcrystalline wax, and/or polyalphaolefin wax) in optimized ratios alongside silane-based primers. These parameter changes enable the coating to maintain strong adhesion even when applied through semi-automatic systems that cannot exert high pressure, thus resolving the contradiction between ease of operation and adhesion strength
Solution Approach 2:
The patent introduces a specially formulated coating agent as an intermediary layer between the basic frame and industrial clay. This intermediary contains wax components that create optimal bonding conditions, enabling strong adhesion to be achieved even with reduced application pressure from semi-automatic systems, thus resolving the contradiction between ease of operation and adhesion strength
3Object-affected harmful factors
If barrier layer such as shellac is applied to basic frame, then dust contamination is prevented, but adhesion between clay and basic frame is reduced
Solution Approach 1:
The patent replaces the conventional shellac barrier layer with a composite coating agent containing silane-based primers and specific wax components in defined ratios. This composite formulation simultaneously provides dust barrier functionality and maintains strong adhesion properties, resolving the contradiction between contamination protection and adhesion strength that plagues conventional shellac-based solutions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly enhances the adhesion between the basic frame and industrial clay, as demonstrated by increased tensile strength, and prevents aerosol formation during spraying, ensuring effective bonding and reduced contamination.
Implementation Method 1
The base wax portion is present as a wax and/or wax blend the melting range of which is between 60° C. and 80° C. The melting point of the base wax portion is therefore somewhat below the application temperature/processing temperature of the industrial clay, which is approximately 80° C.
Implementation Method 2
The coating agent in accordance with the invention consists of at least one wax/wax portion as well as other optional additives. The at least one wax portion is present as a base wax portion and a synthetic wax portion.
