According to different deposition methods, coating processes can be divided into physical vapor deposition (PVD), chemical vapor deposition (CVD), electroplating, solution deposition, spraying, etc. Commonly used coating materials include metals (such as aluminum, gold, chromium), non-metals (such as silicon carbide, silicon nitride), and organic polymers, etc. These materials have unique physical, chemical and mechanical properties and can meet the requirements of different applications.

[0003] The existing Chinese patent with the publication number CN106893299A can be referred to. It discloses a flame-retardant composite material for automotive instrument panel decorative parts. The flame-retardant composite material according to the weight parts of raw materials includes: 50 - 100 parts of polycarbonate, 0.5 - 5 parts of sodium hypophosphite, 5 - 25 parts of glass fiber, 2 - 10 parts of plasticizer, 1 - 10 parts of titanium dioxide, 0.1 - 10 parts of antioxidant, 5 - 25 parts of triphenyl phosphate, 5 - 25 parts of diphenyl phosphite, 0.5 - 5 parts of compatibilizer, 0.1 - 5 parts of coupling agent, and 3 - 20 parts of water.

It is made of the flame-retardant composite material. The flame-retardant composite material has high impact strength, good mechanical strength, high flame-retardant performance, no harm to human health, and ensures the driving safety of the vehicle. The preparation process of the present invention is simple, easy to industrialize, and has broad market application prospects.

[0004] This patent discloses a flame-retardant composite material for decorative parts, and it is stated that it is made of the flame-retardant composite material. The interaction of polycarbonate, sodium hypophosphite, glass fiber, plasticizer, titanium dioxide, antioxidant, triphenyl phosphate, diphenyl phosphite, compatibilizer, coupling agent, etc. makes the decorative part of the flame-retardant composite material have high impact strength, good mechanical strength, high flame-retardant performance, no harm to human health, and ensures the driving safety of the vehicle.

[0005] Although it has the effect of flame resistance, its manufacturing cost is relatively high. It is made by mixing a variety of flame-retardant materials. For the automotive parts in normal daily driving, its role is not prominent. In the event of a fire, the few minutes before flashover are often the most valuable for escape. The fireproof performance of its decorative part only needs to last until the operator can escape safely. Therefore, the inventor of the present invention has proposed a coated flame-retardant decorative part to solve the above-mentioned technical problem of reducing the manufacturing cost of the decorative part. Content of the Utility Model

[0008] The coating is sprayed on the surface of the plate, which can enhance the wear resistance and corrosion resistance of the plate and increase the service life of the plate. The plate consists of an upper plate and a lower plate, and is a detachable structure, which makes maintenance and replacement more convenient and reduces maintenance costs. The connecting components between the upper plate and the lower plate ensure the stability of the structure and facilitate disassembly. Filling grooves are opened in the middle of the upper plate and the lower plate, and flame retardants are filled in them. This design brings significant safety performance improvements. Flame retardants can effectively prevent the spread of fire, especially when a fire occurs, it can slow down the spread of the fire and buy more time for personnel evacuation and fire fighting. In addition, flame retardants can also reduce the degree of burning of the plate in a fire, reduce the damage to the plate by the fire, and further improve the safety and reliability of the plate.

[0009] Furthermore, the connecting component includes a connecting hole and a connecting piece, the connecting hole and the connecting piece are coaxially arranged, and the connecting hole and the connecting piece are gap-matched. The coaxial arrangement can ensure that the connecting hole and the connecting piece can be accurately aligned during assembly to avoid offset or misalignment, thereby improving the stability and reliability of the connection, and the gap arrangement allows the connecting piece and the connecting hole to have a certain amount of movement space after assembly. This design can absorb and compensate for minor deformations and displacements caused by factors such as thermal expansion of materials and mechanical vibration, thereby reducing stress concentration in the connecting components and extending the service life of the plate body. In addition, the gap arrangement can also facilitate the disassembly and replacement of the upper plate body and the lower plate body, reducing maintenance costs.

[0010] Furthermore, the flame retardant is composed of PP halogen-free flame retardant, the main component of PP halogen-free flame retardant is inorganic phosphorus-nitrogen flame retardant monomer, mainly including piperazine pyrophosphate, ammonium polyphosphate, aluminum hypophosphite, aluminum hydroxide and other formulation systems. The flame retardant mechanism of PP halogen-free flame retardant is that the phosphorus, nitrogen and carbon components in the flame retardant jointly produce non-combustible gas with flame retardant effect, phosphate covering layer and carbon layer with insulating effect. The three work together to achieve the flame retardant effect. PP halogen-free flame retardant is used as a flame retardant and is used together with the flame retardant board for flame retardancy, thereby reducing the flame leakage caused by the jet of beam flames caused by pressure.

[0011] Furthermore, a metal frame for auxiliary position limitation is connected to the outer side surface of the plate body; the metal frame provides stable structural support, enhances the overall stability of the plate body, and prevents the upper plate body and the lower plate body from detaching during the connection process. Secondly, the metal frame can accurately limit the position of the plate body to ensure that there is no deviation or dislocation during installation or use. In addition, the metal frame is made of aluminum and has good corrosion resistance and wear resistance.

[0012] Furthermore, the plate body is made of a flame-retardant board; the beneficial effect of the plate body being made of a flame-retardant board is mainly reflected in its fireproof performance.

In addition, the flame-retardant board also has high strength and stability, can maintain the integrity and functionality of the structure, and plays an important role in emergency situations such as fires. Therefore, using a flame-retardant board for the plate body can significantly improve the fire safety performance of the overall structure.

[0013] Furthermore, the coating layer is composed of silicon carbide; silicon carbide has extremely high hardness and is more wear-resistant than traditional metal coatings, which can effectively extend the service life of materials. This property makes silicon carbide coatings widely used in the surface protection of wear-resistant parts. In addition, silicon carbide coatings have good chemical stability in harsh environments such as acids and alkalis, are not easily corroded, and have a melting point as high as 2700°C, with excellent high-temperature resistance, and can maintain stability in extremely high-temperature environments. Silicon carbide also has good thermal conductivity, can effectively improve the heat dissipation effect of materials, has a high transmittance in the visible and infrared light bands, and its refractive index and optical transmission performance can be achieved by adjusting the gas phase composition and deposition conditions. Using silicon carbide as the material for the coating layer reduces the probability of damage to the surface of the plate body during the electroplating process.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The structural setting of spraying a coating layer on the surface of the plate body can enhance the wear resistance, corrosion resistance, etc. of the plate body, improve the service life of the plate body. The plate body is composed of an upper plate body and a lower plate body and is a detachable structure, making maintenance and replacement more convenient and reducing the maintenance cost. The connection components between the upper plate body and the lower plate body ensure the structural stability and also facilitate disassembly;

[0015] Moreover, filling grooves are provided in the middle parts of the upper plate body and the lower plate body, and a flame-retardant substance is filled therein. This design brings a significant improvement in safety performance. The flame-retardant substance can effectively prevent the spread of fire. Especially during a fire, it can slow down the spread speed of the fire, buying more time for personnel evacuation and fire extinguishing work. In addition, the flame-retardant substance can also reduce the burning degree of the plate body during a fire, reduce the damage to the plate body caused by the fire, and further improve the safety and reliability of the plate body;

[0016] When a flame is generated, due to the uneven pressure, the flame may appear in a bundle shape and be ejected under the action of the pressure. The plate body initially protects the ejected bundle-shaped flame to prevent the flame from leaking out. When the plate body is punched out into a hole shape by the pressure and exposes the surface of the flame retardant, the flame retardant provides secondary protection for the bundle-shaped flame to prevent the flame from leaking out. Through the two-fold protection of the flame, the role of separate protection is achieved, thereby achieving the flame retardant effect and facilitating the operator to have the best escape time.
