Therefore, they cannot be understood as limitations on the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The following is combined with Figure 1-4 The utility model is further described.

[0021] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an insulating mica board.

[0022] The specific technical scheme includes an inner interlayer 1, an adhesive layer 2, a toughening layer 3, a reinforcing layer 4 and a waterproof layer 5. Both sides of the inner interlayer 1 are coated with the adhesive layer 2, the side of the adhesive layer 2 away from the inner interlayer 1 is bonded with the toughening layer 3, the side of the toughening layer 3 away from the adhesive layer 2 is bonded with the reinforcing layer 4, and the waterproof layer 5 is coated on the side of the reinforcing layer 4 away from the toughening layer 3.

[0023] The inner interlayer 1 is provided with multiple layers of mica paper, and the number of layers of mica paper can be set according to actual needs. The mica papers of the layers in the inner interlayer 1 are bonded by an adhesive layer 2, and the adhesive layer 2 uses organic silicone water. A layer of organic silicone water is coated on each layer of mica paper, and a layer of mica paper is covered on the organic silicone water. The mica paper and the organic silicone water are connected in sequence at intervals. The toughening layer 3 is connected to the inner interlayer 1 by the adhesive layer 2. The toughening layer 3 can increase the toughness of the mica board. The reinforcement layer 4 is coated on the toughening layer 3, which can increase the toughness of the toughening layer 3, which can be beneficial to improving the toughness of the mica board. The waterproof layer 5 is coated on the reinforcement layer 4, and the inner interlayer 1, the adhesive layer 2, the toughening layer 3 and the reinforcement layer 4 can be waterproofed. The inner interlayer 1, the adhesive layer 2, the toughening layer 3, the reinforcement layer 4 and the waterproof layer 5 form an insulating mica board with waterproof and moisture-proof properties and high toughness.

[0024] The material used for the inner interlayer 1 is mica paper.

[0025] Mica paper is made of high-quality muscovite from Sichuan. It is broken into pulp and papermaking through thermochemical or hydraulic stripping, and then cut into continuous rolls or single sheets. Mica paper is an insulating material with good performance and can be used in a wide range of fields. It can be used as an insulating material in motors.

[0026] The material used for the adhesive layer 2 is organic silicone water.

[0027] Silicone has basic properties such as low surface tension, small viscosity-temperature coefficient and high gas permeability. It also has the advantages of high and low temperature resistance, electrical insulation, oxidation stability, flame retardancy, hydrophobicity, corrosion resistance and non-toxicity and odorlessness. It is widely used in construction, transportation, chemical, textile, food, light industry and medical industries, and is suitable for docking and bonding between silicone and silicone, metal, plastic and glass.

[0028] The material of the toughening layer 3 is glass fiber reinforced plastic.

Glass fiber reinforced plastic is a new functional material made of synthetic resin and glass fiber through a composite process. Glass fiber reinforced plastic material has the advantages of light weight, high specific strength, corrosion resistance, good electrical insulation performance, slow heat transfer, good thermal insulation and good resistance to instantaneous ultra-high temperature, which can increase the toughness of mica board.

[0030] The reinforcement layer 4 is made of polyurethane paint material.

[0031] Polyurethane paint is polyurethane paint. Polyurethane paint has the characteristics of strong paint film, rich gloss, strong adhesion, water resistance, wear resistance and corrosion resistance. It is widely used in high-end wooden furniture and can also be used on metal surfaces. Applying polyurethane paint on the surface of the toughening layer 3 can increase the toughness of the toughening layer 3. At the same time, it is wear-resistant and can reduce the wear rate. The advantage of strong adhesion can increase the stability of the connection with the toughening layer 3 and prevent it from falling off.

[0032] The material used for the waterproof layer 5 is acrylic waterproof coating.

[0033] Acrylic waterproof coating is a one-component water-based waterproof coating made with pure acrylic polymer emulsion as the base material and other additives added. The waterproof film formed after curing has certain elongation, elasticity, plasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, anti-seepage and protection. The waterproof coating has good temperature adaptability, is easy to operate, and is easy to repair and maintain.
