Amphipathic Coated Cellulose Paper for Oil-Immersed Transformers

The patent applies composite materials by combining cellulose base material with amphipathic molecules that have both hydrophobic hydrocarbon groups and hydrophilic functional groups. This composite structure provides both the mechanical strength of cellulose and the water/heat resistance of the amphipathic coating, resolving the contradiction between durability and manufacturing complexity.

The patent changes the chemical parameters of the insulating paper surface by introducing amphipathic molecules with specific functional groups (carboxyl, hydroxyl, amino, or epoxy groups). This parameter change enhances water repellency and heat resistance without fundamentally changing the manufacturing process, thus improving durability while controlling costs.

The patent uses composite materials by coating cellulose with amphipathic molecules that provide thermal stability. The hydrophobic hydrocarbon groups and hydrophilic functional groups work together to create a structure that resists thermal degradation, improving heat resistance while maintaining cost-effectiveness through a relatively simple coating process.

The patent modifies the thermal parameters of the insulating paper by introducing amphipathic molecules with stable chemical bonds. These molecules raise the decomposition temperature and improve heat resistance through chemical parameter changes rather than requiring complex manufacturing processes.

The patent applies composite materials by combining hydrophilic functional groups that attract insulating oil with hydrophobic groups that repel water. This dual-nature composite structure improves impregnating ability with insulating oil while maintaining a relatively simple single-step coating manufacturing process.

The patent changes the surface chemical parameters of the insulating paper by introducing amphipathic molecules with specific functional groups. These parameter changes enhance oil impregnation through improved wettability and capillary action without requiring complex multi-step manufacturing processes.
