[0028] First embodiment

[0029] The present invention provides an emergency coated cloth fire blanket for electric vehicles, comprising: a base fabric layer made of fiber material; a fireproof coating composed of fireproof and heat-insulating materials, the fireproof coating being used to be coated on the base fabric layer; the materials of the fireproof coating comprising chloroprene rubber and CSM; a waterproof layer arranged on the outside of the fireproof coating; and a connecting layer arranged on the inside of the base fabric layer, for fixing the fire blanket on the electric vehicle. The materials of the base fabric layer comprise glass fiber and aramid fiber.

[0030] In this embodiment, the base fabric layer is the basis of the fire blanket and is made of high-strength, high-temperature resistant fiber materials, specifically glass fiber and aramid fiber. Glass fiber is widely used in fireproof materials due to its excellent mechanical strength and heat resistance, while aramid fiber is known for its excellent flame retardancy and chemical corrosion resistance. The combination of the two can significantly improve the overall performance of the fire blanket. The fireproof coating is located on the base fabric layer and is carefully proportioned by fireproof and heat-insulating materials. The main components include chloroprene rubber (Neoprene) and CSM (chlorosulfonated polyethylene). Neoprene not only has good elasticity, but also has excellent weather resistance and oil resistance, which can effectively isolate flames; and CSM, as a high-performance synthetic rubber, has a unique chemical structure that gives it excellent flame retardancy and corrosion resistance. The combination of the two enables the fireproof coating to play the best protective effect when facing high temperature and flames. The waterproof layer is arranged on the outside of the fireproof coating and is made of special waterproof materials to prevent moisture penetration and ensure that the fire blanket can still maintain good fireproof performance in a humid environment. This design is particularly important for electric vehicles, as moisture may damage electrical components such as batteries, thereby increasing the risk of fire. The connecting layer is set on the inner side of the base fabric layer and is usually composed of adhesives or mechanical fixings to firmly fix the fire blanket to specific parts of the electric vehicle, such as around the battery pack or near key electronic components. This design ensures the stability of the fire blanket during vehicle driving, while facilitating quick installation and removal, improving the speed of emergency response.

[0031] Second embodiment

[0032] See also Figure 1 The present invention also provides a method for preparing an emergency coated cloth fire blanket for electric vehicles, comprising:

[0033] S201 coats the fireproof and heat-insulating material on the base fabric layer through a coating device to form a fireproof coating;

[0034] First, select suitable fireproof and heat-insulating materials, such as chloroprene and CSM (chlorosulfonated polyethylene), and adjust their proportions and concentrations according to the required performance. Then, using advanced coating equipment, these materials are evenly coated on the base fabric layer. The base fabric layer is interwoven with pre-prepared glass fiber and aramid fiber, which are selected for their high melting point and chemical stability. This step requires precise control of the coating process to ensure that the fireproof coating is uniform in thickness, free of bubbles and impurities, and achieves the best fireproof and heat-insulating effect.

[0035] After S202 coating is completed, vulcanization treatment is carried out;

[0036] After the fire-retardant coating is formed, it needs to be placed under specific conditions for vulcanization. Vulcanization is a chemical process that cross-links the molecular chains of rubber-like materials under heating conditions by adding sulfur or other vulcanizing agents, thereby enhancing their physical properties, such as hardness, elasticity and heat resistance. This process is critical for fire-retardant coatings because it not only improves the durability and stability of the coating, but also enhances its flame-retardant properties to ensure that it remains effective even in extreme temperatures.

[0037] S203 applies a waterproof coating on the outside of the vulcanized fire retardant coating;

[0038] In order to further enhance the comprehensive protection capability of the fire blanket, a waterproof coating needs to be applied on the surface of the vulcanized fireproof coating. The waterproof coating is usually made of high molecular polymer materials and has excellent waterproof and breathable properties. The addition of this layer can effectively prevent moisture penetration, avoid electrical short circuits or battery failures caused by water vapor, and ensure that the fireproof effect of the fire blanket in a humid environment is not affected.

[0039] S204 Finally, a connecting layer is bonded to the inner side of the base fabric layer.

[0040] A connecting layer needs to be bonded to the inside of the fire blanket, that is, the inner side of the base fabric layer. The connecting layer can be a special adhesive or a mechanical fastener, and its function is to firmly fix the fire blanket to a specific position in the electric vehicle, such as around the battery pack or near the motor. This step ensures the stability of the fire blanket during vehicle operation, and also facilitates rapid deployment and replacement in emergency situations. The bonding of the connecting layer must ensure that there are no bubbles or looseness to maintain the integrity and reliability of the entire fire protection system.
