Polyoxyalkylene Acrylic Composition for Pump-Out-Resistant Thermal Interface

The patent applies phase transition by curing the liquid composition containing polymerizable compounds to transform it into a solid gel状 cured product. This phase change from liquid to solid eliminates dripping and pump-out phenomena while maintaining thermal conduction capability through the gel structure that retains thermal contact.

The patent uses composite materials by combining polymerizable compounds with thermally conductive fillers in a specific composition ratio. This composite structure provides both the thermal conduction properties of the filler particles and the structural integrity of the cured polymer matrix, preventing pump-out while maintaining heat transfer efficiency.

The patent applies parameter changes by carefully controlling the composition ratios of polymerizable compounds (5-50 mass%), thermally conductive fillers (50-95 mass%), and other additives. By optimizing these parameters, the cured product achieves both sufficient breaking strength (0.5 MPa or more) and dripping resistance simultaneously.

The patent uses composite materials with thermally conductive fillers dispersed in a cured polymer matrix. This composite structure provides both mechanical strength from the polymer network and thermal conduction from the filler particles, while the gel structure prevents dripping.

The patent applies parameter changes by specifying precise composition ranges: polymerizable compounds at 5-50 mass%, thermally conductive fillers at 50-95 mass%, and controlled amounts of other additives. This parameter optimization ensures both high breaking strength and excellent compatibility by preventing filler aggregation and ensuring uniform dispersion.

The patent applies local quality by ensuring uniform distribution of polymerizable compounds around thermally conductive filler particles. This local optimization of composition around each filler particle ensures good interfacial compatibility and stress transfer, maintaining both strength and filler compatibility.
