Description

Technical Field

[0001] The utility model relates to the field of mica insulating materials, in particular to a high-temperature resistant soft mica plate. Background Art

[0002] Mica is a naturally occurring layered silicate mineral with excellent physical and electrical properties and the ability to maintain these properties 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 non-toxic, odorless, resistant to aging and corrosion.

[0003] Mica boards are widely used in industrial machinery and equipment due to their pressure resistance and temperature resistance. Mica boards include hard mica boards and soft mica boards. Hard mica boards are mainly made of muscovite mica paper glued with methyl polysiloxane resin and then pressed. This type of mica board has high strength, but is not flexible enough and is easy to delaminate. This type of mica board is mainly used in machinery, metallurgy, household appliances and other industries; soft mica boards are mainly made of phlogopite mica paper or synthetic mica paper glued with methyl phenyl polysiloxane resin and then pressed. This type of mica board has good flexibility and is easy to roll into shape, but is not strong enough and is easy to deform. This type of mica board is mainly used in electric heating equipment that requires winding, such as hair dryers, microwave ovens, electric soldering irons, toasters, and as an asbestos substitute in industries such as automobile exhaust pipe gaskets.

[0004] With the rapid development of new energy and new quality productivity, the performance and functions of mica board materials currently developed and produced are far from keeping up with the needs of modern industrial development and cannot meet the needs of the insulation material market. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a high temperature resistant soft mica plate which can be wound, folded, rolled and stamped.

[0006] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0007] 1. A high temperature resistant soft mica board, characterized in that: the high temperature resistant soft mica board comprises a mica paper layer and a mica tape layer, the mica paper layer is bonded to the mica tape layer at high temperature, the mica paper layer comprises N layers of phlogopite mica paper, the mica tape layer comprises a single layer of phlogopite mica paper and glass fiber cloth, and the single layer of phlogopite mica paper is bonded to the glass fiber cloth by an epoxy resin adhesive.

[0008] Furthermore, the glass fiber cloth is E-GLASS alkali-free glass cloth.

[0009] Furthermore, the mica paper layer comprises N layers of phlogopite mica paper, and each layer of phlogopite mica paper is bonded by epoxy resin adhesive.

[0010] Furthermore, the number of layers of the N-layer phlogopite mica paper is 2-13 layers.

[0011] Furthermore, the single-layer phlogopite paper has a basis weight of 120-160 g / ㎡ and a thickness of 0.09-0.10 mm.

[0012] The beneficial effects of the utility model are:

[0013] Through the composite high-temperature pressing of mica tape and multi-layer mica paper, the product can be wound, folded, curled, and stamped. It can burn for 10 minutes without penetrating the material and has excellent electrical insulation and high temperature resistance. It is particularly suitable for fireproof insulation of new energy vehicle battery packs. It can also be used in new energy vehicles to resist shock, aging, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the utility model;

[0015] In the figure: 1-mica tape layer, 2-mica paper layer, N-mica paper layer. DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] See also Figure 1 A high temperature resistant soft mica board, the high temperature resistant soft mica board comprises a mica paper layer and a mica tape layer, which is formed by bonding the mica paper layer and the mica tape layer and then pressing them at high temperature.

[0018] First, a single-layer phlogopite paper roll and a glass fiber cloth roll are mounted on the dryer head, and then the phlogopite mica and the glass fiber cloth are pulled through a pulling roller, a gluing roller and a compounding roller for gluing and compounding. The compounded adhesive is an epoxy resin adhesive, which is composed of epoxy resin, plasticizer, toughening agent, filler and curing agent.

[0019] The composite phlogopite paper and glass fiber cloth are then drawn into a dryer and dried at 60-80° C. for 30 minutes to form a mica tape.

[0020] Then, N layers of glued phlogopite paper are bonded by epoxy resin adhesive, dried and pressed in a press to form a high temperature resistant soft mica sheet.

[0021] The soft mica sheet and the mica tape layer are compounded by epoxy resin adhesive, dried and pressed in a press to make a high temperature resistant soft mica board.
