Adhesive Tape With Silicone-Coated Particles For Drop Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive tapes used for fixing parts and labels lack high drop impact resistance, leading to peeling off or breaking when dropped, and are difficult to remove during disassembly, especially in densely mounted parts.
Innovation Solution
The development of an adhesive tape with an adhesive layer containing particles with an average diameter of 4 to 40 μm and a silicone resin surface, and an adhesive resin, where the particles are dispersed in the adhesive resin in a predetermined ratio, enhancing drop impact resistance and ease of removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adhesive tapes are used for fixing parts, then adhesive reliability is maintained, but drop impact resistance is insufficient causing peeling or breaking
Solution Approach 1:
The adhesive layer is formulated as a composite material containing rubber resin (providing elasticity and impact absorption), silicone resin (providing adhesion and flexibility), and inorganic particles (providing reinforcement and structural stability). This composite structure enables the adhesive to simultaneously achieve high adhesive reliability and exceptional drop impact resistance by combining the complementary properties of different materials.
2Productivity
If adhesive tapes are pulled at high angles for rapid removal, then removal speed increases, but the adhesive tape tears off
Solution Approach 1:
The adhesive composition parameters are optimized to achieve a balance between adhesion strength and release ease. The specific ratios of rubber resin (30-70 parts), silicone resin (10-60 parts), and inorganic particles (5-50 parts) create an adhesive layer with controlled cohesive strength that allows rapid removal at high angles without tearing, while maintaining strong fixation during normal use.
3Ease of repair
If adhesive tape is removed from densely mounted parts, then disassembly is achieved, but the operation becomes complicated and time-consuming
Solution Approach 1:
The adhesive tape is designed with a base material layer that has been pre-separated from the adhesive layer, allowing the adhesive to be cleanly extracted and removed as a single unit from densely mounted parts. This extraction design eliminates the need for complex step-by-step removal operations, significantly reducing both operational complexity and time required for disassembly of products with multiple adhesive tapes.
