Description

Technical Field

[0001] This utility model relates to the field of mica insulation materials, and in particular to a mica composite plate with embedded steel plate. Background Technology

[0002] Mica is a naturally occurring layered silicate mineral with excellent physical and electrical properties, which it retains even at high temperatures. It is completely chemically inert and non-flammable. Most importantly, it is resistant to high voltage, corona discharge, and radiation, and is also non-toxic, odorless, resistant to aging, and corrosion.

[0003] The main products in the current mica insulation material field include mica paper, mica board, and mica tape. Mica board is made by laminating multiple layers of glued mica paper and then pressing them at high temperature in one go. The product is resistant to high temperature and high pressure, and has high strength. It is mainly used in the electrical and home appliance industries.

[0004] Mica sheets include soft mica sheets bonded and pressed with epoxy resin adhesive and hard mica sheets bonded and pressed with silicone adhesive. Soft mica sheets have a certain degree of flexibility and wrapping properties, but their resilience and hardness are insufficient. Hard mica sheets have better hardness and a certain riveting function, but their flexibility and wrapping properties are insufficient. The components in new energy vehicles under the new quality productivity not only require good thermal conductivity and riveting function, but also good heat insulation and insulation functions, and even more importantly, good flexibility, wrapping properties, resilience and hardness.

[0005] With the rapid development of new energy and new quality productivity, single-purpose mica panels are far from meeting the needs of modern industrial development and the demands of the new energy electric vehicle market. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cloud board with excellent mechanical properties, thermal conductivity and riveting function, and also requires good flexibility, wrapping properties, resilience and a certain degree of hardness.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] An embedded steel plate mica composite panel includes a mica plate and a steel plate, characterized in that: the mica plate includes a soft mica plate and a hard mica plate, the soft mica plate is formed by bonding and pressing multiple layers of phlogopite paper with epoxy resin, and the hard mica plate is formed by bonding and pressing multiple layers of white mica paper with silicone resin; the inner surfaces of the soft mica plate and the hard mica plate are coated with a silicone resin layer, and the steel plate is embedded between the soft mica plate and the hard mica plate.

[0009] Preferably, the soft mica board is made of multiple layers of phlogopite paper bonded and pressed together with epoxy resin, and the hard mica board is made of multiple layers of muscovite paper bonded and pressed together with silicone resin.

[0010] Preferably, the thickness of the soft mica plate is 1.3-1.5 mm and the thickness of the hard mica plate (2) is 1.0-1.3 mm.

[0011] Preferably, the silicone resin is 9603 silicone resin and the epoxy resin is AFG90 epoxy resin.

[0012] Preferably, the steel plate (3) is a 304 stainless steel plate with a thickness of 1-1.5mm.

[0013] The beneficial effects of this utility model are:

[0014] This utility model embeds steel plates into phlogopite and muscovite plates, which not only have thermal conductivity and riveting function, but also good flexibility, wrapping properties, resilience and hardness. It is a bold attempt to apply mica products to new energy electric vehicles, which greatly improves the quality of new energy electric vehicles and extends their service life.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] See Figure 1 An embedded steel plate mica composite panel is characterized by comprising a soft mica plate, a hard mica plate, and a steel plate. The soft mica plate is formed by bonding and pressing multiple layers of phlogopite paper with epoxy resin, and the hard mica plate is formed by bonding and pressing multiple layers of white mica paper with silicone resin. The inner surfaces of the soft mica plate and the hard mica plate are coated with a silicone resin layer, and the steel plate is embedded between the soft mica plate and the hard mica plate.

[0019] Several sheets of phlogopite paper coated with epoxy resin are stacked together and then pressed in a press to form a soft mica board. Several sheets of white mica paper coated with silicone resin are then pressed in a press to form a hard mica board. Silicone is then coated on the inner surfaces of the soft and hard mica boards, and a steel plate is embedded between the soft and hard mica boards. Finally, the boards are pressed again to obtain a steel plate-embedded mica composite board required for Xinyuan electric vehicles.
