Description

Technical Field

[0001] The utility model relates to the technical field of epoxy boards, in particular to a flame-retardant insulating epoxy board. Background Art

[0002] Epoxy board is a composite material made of epoxy resin and glass fiber, which has high mechanical strength, heat resistance, corrosion resistance and insulation performance.

[0003] In the existing technology, epoxy board is the main base material for circuit board production, and circuit board is one of the main components of contemporary PC products and plays an irreplaceable role. Although epoxy board has strong insulation and heat resistance, with the increasing power consumption and integration of electronic products, the performance requirements for epoxy board are also gradually increasing. At present, the commonly used epoxy boards on the market are gradually unable to meet mainstream needs. Therefore, it is necessary to develop an epoxy board with high insulation and high flame retardant effect. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology. The insulation performance and flame retardant performance of many commonly used epoxy boards on the market have obviously lagged behind market demand and cannot meet the growing quality requirements.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a flame-retardant insulating epoxy board, comprising a first epoxy board and a second epoxy board, the first epoxy board being located directly above the second epoxy board and being made of the same material, the first epoxy board being suspended directly above the second epoxy board, and a gap being reserved between the two, a plurality of horizontal bars and vertical bars being installed inside the gap, a plurality of the horizontal bars and vertical bars being crossed with each other, and forming a plurality of segmented reserved cavities of the same size, and a plurality of the segmented reserved cavities being arranged in a rectangular shape.

[0006] Optionally, the second epoxy plate is provided with an insulating frame away from the first epoxy plate, and the number of the insulating frames is four and they are arranged in a rectangular shape.

[0007] Optionally, each of the four insulating frames is provided with a rubber suction cup at one end away from the second epoxy board.

[0008] Optionally, a heat insulation structure is installed inside the segmented reserved cavity.

[0009] Optionally, the first epoxy sheet material and the second epoxy sheet material include a glass fiber layer and an insulation layer from the outside to the inside.

[0010] Optionally, a layer of graphite heat dissipation film is sprayed on the outer side of the glass fiber layer.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] In the present utility model, a plurality of horizontal bars and vertical bars are added between the first epoxy sheet and the second epoxy sheet, thereby improving the compressive resistance of the two epoxy sheets, increasing the overall rigidity and strength, and improving the load-bearing capacity and bending resistance of the epoxy sheets. In addition, a plurality of horizontal bars and vertical bars are crossed to form a plurality of segmented reserved cavities, which can further enhance the insulation performance of the insulation layer. The cross structure of the horizontal bars and vertical bars can effectively reduce the uneven distribution of the electric field in the insulation layer, reduce the electric field strength, and thus enhance the insulation effect. At the same time, the segmented reserved cavity structure can delay the spread of fire and increase the flame retardant time of the material. Moreover, due to the existence of the segmented reserved cavity, heat and flame will be effectively blocked during the transmission process, further improving the flame retardant performance of the material.

[0022] In this embodiment, by adding a plurality of horizontal bars 5 and vertical bars 6 between the first epoxy sheet 1 and the second epoxy sheet 2, the compressive resistance of the two epoxy sheets is improved, and the overall rigidity and strength are increased, thereby improving the load-bearing capacity and bending resistance of the epoxy sheets. In addition, a plurality of horizontal bars 5 and vertical bars 6 are crossed to form a plurality of segmented reserved cavities 7, which can further enhance the insulation performance of the insulating layer 13. The cross structure of the horizontal bars 5 and the vertical bars 6 can effectively reduce the uneven distribution of the electric field in the insulating layer 13, reduce the electric field strength, and thus enhance the insulation effect. At the same time, the segmented reserved cavity 7 structure can delay the spread of fire and increase the flame retardant time of the material. Moreover, due to the existence of the segmented reserved cavity 7, heat and flames will be effectively blocked during the transmission process, further improving the flame retardant performance of the material. In addition, the segmented reserved cavity 7 can provide an additional channel for heat dissipation, reduce the temperature increase of the material caused by heat accumulation, and help maintain the stability of the material and extend its service life.

[0024] In this embodiment, the rubber suction cup 4 and the insulating frame 3 can easily fix the flame-retardant insulating epoxy board tightly on various planes by virtue of the adsorption capacity of the rubber suction cup 4 during the fixation and transportation of the flame-retardant insulating epoxy board, thereby simplifying the loading and transportation process, and the insulating frame 3 provides solid support to ensure the stability of the rubber suction cup 4. In addition, both are made of insulating materials, thereby improving the insulation effect of the epoxy board, and the thermal insulation structure 8 can enhance the flame retardant and heat-resistant effect of the segmented reserved cavity 7.

[0026] In this embodiment, the glass fiber layer 12 can provide excellent strength and rigidity, so that the epoxy board has higher compression, tension and impact resistance, which helps to improve the durability and service life of the product, and also has a flame retardant function. In addition, the glass fiber layer 12 is sprayed with a layer of graphite heat dissipation film 11, which can increase its flame retardant properties, reduce the risk of combustion, and improve the safety of equipment use.
