Abstract

The invention relates to a packing material for a hatch cover, and more specifically relates to a packing material for a hatch cover, which is hollow inside and thus can elastically absorb loads. The packing material for a hatch cover is characterized by comprising a first part and a second part. The first part is formed into an outer frame with a hollow inside, any one face of the upper face and the lower face is open, is made of a first rubber material, and performs elastic deformation with combination with a pressure lever of the hatch cover. The second part is formed inside the first part and is made of a second rubber material. The second part has the following forms by comprising more than two hollow structures and more than one post between the hollow structures. Therefore, according to the packing material, a shape restoration ratio can be improved through the hollow structures inside the packing material; the packing material is made by a continuous vulcanization method and can have stable cross sections, and the time for manufacturing process can be shortened when the continuous vulcanization method is compared with conventional injection moulding methods.

Description

technical field [0001] The invention relates to a hatch cover with sealing material [0002] More specifically, it relates to a sealing material for a hatch cover in which a hollow is formed inside the sealing material so as to elastically absorb a load while maintaining a seal, and a method for manufacturing the same. Background technique [0003] A cargo ship or a container ship is provided with a hold for storing grain, crude oil, cargo, containers, etc., and the upper part of the hold is provided with a hatch, and the hatch is formed with an opening through which cargo can enter and exit. In order to prevent foreign matter or seawater from entering the cabin while the ship is moving, it is necessary to seal the opening of the hatch cover, and a hatch cover is used for this purpose. Moreover, the inner edge of the hatch cover is provided with a sealing material, so as to play the role of cushioning and maintaining sealing. [0004] figure 1 A side sectional view sh...
