Problems solved by technology

In addition, the ship engine room and crew living quarters are key areas for fire prevention, and fire accidents are prone to occur during ship operation, and the marine climate is easy to spread the fire.
Since ships often travel in the sea, seawater and sea breeze have great corrosion damage to the hull. Although many anti-corrosion technologies have been used in the prior art, such as anti-corrosion coatings, the anti-corrosion time of the anti-corrosion coatings used is short, and the impact resistance Weak, poor wear resistance

Abstract

The invention relates to the technical field of marine equipment, and particularly provides a flame-retardant corrosion-resistant watertight door which comprises a door frame and a door plate. The door frame and the door plate are rotatably connected through hinges positioned on one side of the door frame, a shackle is mounted on the other side of the door frame, a coaming is arranged on the inner side of the edge of the door plate peripherally, a mounting groove is formed between the coaming and the edge of the door plate and filled with sealing padding, the sealing padding comprises a sponge body, a mucilage layer and a rubber wrapper, the mucilage layer coats the outer surface of the sponge body, and the rubber wrapper coats the outer surface of the mucilage layer; an inner cover plate is arranged on the inner side of the door plate and fixed on the coaming, a sound absorbing layer and a light soundproof plate are arranged between the inner cover plate and the door plate, a corrosion-resistance coating layer coats the surface of the door plate, and a high-temperature-resistant coating layer coats the surface of the light soundproof plate. The flame-retardant corrosion-resistant watertight door has the advantages that the door plate is good in pressure-resistant performance and sealing effect, interference on seamen by noise can be avoided, and the door is fireproof, flame-retardant, resistant to high temperature, lasting in corrosion resistance and good in wear-resistant performance.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a flame-retardant and corrosion-resistant watertight door. Background technique [0002] With the popularization of water transportation and the development of shipbuilding industry, customers have higher and higher requirements for ship outfitting equipment. As an indispensable part of the ship, the watertight door is an important entrance for staff to enter and exit. However, the existing watertight door bears less pressure and has poor pressure resistance. Since the ship has been in the harsh marine environment for a long time, it is often corroded by salt spray, sea water and marine atmosphere. Therefore, higher requirements are put forward for the sealing of watertight doors. In addition, ship engine room and crew living quarters are key areas for fire prevention, and fire accidents are prone to occur during ship operation, and the marine climate is easy to spread f...
