Description

Technical Field

[0001] The utility model relates to the technical field of middle roof plates, in particular to a ceramic spraying middle roof plate based on the interior decoration of a rail transit vehicle. Background Art

[0002] The interior materials of urban rail transit vehicles mainly affect the weight index, performance, function and quality of the vehicles. In order to save energy and reduce consumption, higher requirements are placed on the fire resistance, lightweight and surface durability of the materials, which continuously promotes the evolution of interior materials to new high-tech materials. The selection of interior materials is determined by the comprehensive performance of the materials such as the modeling process, decorative effect, and mechanical properties. Commonly used interior materials are aluminum honeycomb composite panels, aluminum profiles and fiberglass. Among them, aluminum honeycomb composite panels are often used for the middle roof panels, floors, passenger compartment partitions and driver compartment partitions, aluminum profiles are often used for side roof panels and air supply grilles, and fiberglass materials are often used for interior wall panels and complex parts of the interior. The middle roof is an important component of the interior system. It is the first interior decoration of the vehicle that passengers see when entering the vehicle. Therefore, the installation quality of the middle roof panel will directly affect the overall effect of the vehicle and the overall evaluation of the vehicle by passengers. The main deficiencies of the existing middle roof panel interior parts of rail vehicles are as follows:

[0003] (1) In the spraying process of rail vehicle interior parts on the market, water-based environmentally friendly paints have gradually replaced traditional solvent-based paints, which has improved environmental performance. However, water-based paints still have many problems in the coating production process, such as poor wetting, poor atomization, poor leveling, sagging and other defects, which affect the construction and quality of rail vehicle coating.

[0004] (2) The roof panels of existing rail vehicles are usually integral structures, which have certain defects. They are very inconvenient to transport and install, and not easy to use. Some rail vehicle roof panels are pre-divided into multiple pieces. Although this is convenient for transportation and installation, there will be certain gaps at the joints, which will cause moisture in the air to condense and form water in the roof panel, which is prone to dripping. At the same time, if the number of divided roof panels is large, it will affect the stability of the connection relationship, and it is easy to fall, affecting the personal safety of passengers.

[0005] (3) In existing rail vehicles, a large number of air supply holes are opened on the outside of the roof for ventilation. However, during long-term operation, the air supply holes will be contaminated with dust, causing them to contaminate the air flow discharged from the inside, causing the air flow to carry odors, affecting the comfort of people inside the vehicle.
