Description

Technical Field

[0001] The utility model relates to the technical field of mica plates, in particular to a mica plate with a skeleton. Background Art

[0002] Mica is a special sheet silicate mineral. Its crystal structure is a lamellar structure composed of two layers of silicon-oxygen tetrahedrons sandwiched by a layer of aluminum-oxygen octahedron. The special lamellar structure of mica determines that it has extremely high electrical insulation perpendicular to the cleavage plane. At the same time, it also has good transparency, excellent strippability, chemical stability, reducibility, and the ability to maintain the above excellent physical and chemical properties under high temperature conditions. It is a very important insulating material. As an important electrical insulating material, mica insulating materials need to have a sufficiently large area during use. With the depletion of large mica resources, sheet insulating materials prepared from crushed mica through appropriate processing methods have become the mainstream of mica insulation.

[0003] After searching, the Chinese patent with the announcement number CN218948633U discloses a mica composite plate structure, which belongs to the technical field of mica products. It includes at least two stainless steel mesh layers and one more mica paper layer than the stainless steel mesh layers, the stainless steel mesh layers and the mica paper layers are alternately distributed, and a silicone resin layer is coated between the mica paper layer and the stainless steel mesh layer, and the silicone resin passes through the mesh of the stainless steel mesh layer. The utility model has the advantages of high mechanical strength.

[0004] When this patent is actually used, there are the following defects:

[0005] In this patent, when the glue is applied between the mica paper layer and the stainless steel mesh layer, the glue will continuously release and produce a large amount of toxic and harmful gases under high temperature conditions. However, if the amount of glue applied is too little, it will affect the overall structural strength and stability of the mica board, making the mica board structurally unstable after molding and prone to interlayer peeling after continuous use. Utility Model Content

[0006] In view of the technical problem that in the existing patents, when the glue is coated between the mica paper layer and the stainless steel mesh layer, the glue will continuously release and produce a large amount of toxic and harmful gases under high temperature conditions, but if the amount of glue applied is too little, it will affect the overall structural strength and stability of the mica board, resulting in poor structural stability of the mica board after molding, and easy interlayer peeling after continuous use, the utility model provides a mica board with a skeleton.

[0008] By setting the skeleton component, the amount of glue impregnation during hot-pressing and compounding of the impregnated mica paper in the mica board substrate can be effectively reduced, thereby preventing the mica board substrate from peeling off between layers during use.

[0009] Furthermore, the skeleton assembly includes a first skeleton, a second skeleton and a third skeleton.

[0010] Furthermore, the second skeleton is arranged between the first skeleton and the third skeleton, and connecting columns are fixedly installed on one side of the first skeleton and the second skeleton, and connecting grooves are opened on one side of the third skeleton and the other side of the second skeleton, and two adjacent connecting columns correspond to the connecting grooves.

[0011] Furthermore, three clamping blocks are fixedly installed on the peripheral side of the connecting column, and three clamping grooves are opened on the peripheral side of the inner wall of the connecting groove, and the clamping blocks correspond to the clamping grooves.

[0012] By providing the connection columns and connection grooves, the skeleton assembly can be used for mica boards of various thicknesses.

[0013] Furthermore, gaps between the first frame, the second frame, the third frame and the mounting slots are filled with epoxy resin glue by pressure injection.

[0014] Furthermore, glass fiber cloths are arranged on both sides of the mica board substrate, and mica paper is arranged on one side of the two glass fiber cloths and one side of the mica board substrate.

[0015] Furthermore, the mica board substrate is formed by hot-pressing and composite forming of a plurality of mica sheets.

[0016] Furthermore, a carbon fiber fabric layer is arranged between the plurality of mica sheets.

[0017] The beneficial effects of the utility model are as follows: compared with the prior art, in the utility model;

[0018] By setting up the skeleton component, the amount of glue impregnation during hot pressing and compounding of the impregnated mica paper in the mica board substrate can be effectively reduced, and the interlayer peeling of the mica board substrate during use can be prevented, thereby effectively solving the problem that the glue of the existing mica board will continue to release and generate a large amount of toxic and harmful gases under high temperature conditions during production, and if the amount of glue applied is too little, it will affect the overall structural strength and stability of the mica board.
