Method for producing a porous particle composite for an electrical insulating paper |
| 摘要 |
A method is provided for producing an electrical insulation paper having a particle composite. The method involves mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles. The dispersion is sedimented, such that the particles in platelet form are arranged in essentially plane-parallel layers in the sediment. The carrier fluid is removed from the sediment. Energy is introduced into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent. The mass ratio is predetermined such that the particle composite has a porous structure. The insulation paper is thereby produced. |

1. A method for producing an electrical insulation paper comprising a particle composite, comprising the steps of:
mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles, producing a sediment by sedimenting the dispersion, as a result of which the particles in platelet form are arranged in essentially plane-parallel layers in the sediment; removing the carrier fluid from the sediment, introducing energy into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent, wherein the mass ratio is predetermined such that the particle composite has a porous structure, producing the insulation paper. |
