Permanent magnetic force based waterproof rubber strip

Abstract

The invention discloses a permanent magnetic force based waterproof rubber strip. The permanent magnetic force based waterproof rubber strip comprises a rubber strip body and a plurality of neodymium-iron-boron permanent magnetic cores. A magnetic core mounting hole is formed in the bottom end of the rubber strip body and extends along the L direction of the length direction of the rubber strip body to penetrate through the whole rubber strip body, the neodymium-iron-boron permanent magnetic cores are arranged in the magnetic core mounting hole, and a waterproof rubber strip bottom edge is formed between the magnetic core mounting hole and the bottom face of the rubber strip body. The permanent magnetic force based waterproof rubber strip has the advantages that the neodymium-iron-boron permanent magnetic cores and a hull plate produce magnetic force, so that the permanent magnetic force based waterproof rubber strip is attracted on a steel plate surrounding a manhole firmly; working water or rainwater can be prevented from seeping into a ship's space through the manhole or flowing into the ship's space directly, and accordingly substituting magnetic fixing for welding or bolt fixing is achieved.

Description

technical field [0001] The invention relates to the technical field of rubber strips, in particular to permanent magnetic waterproof rubber strips. Background technique [0002] At present, the shipbuilding industry has excess capacity and increasingly fierce competition. In order to improve production efficiency and quality, reduce production costs, and reduce and avoid repeated construction, it has become an urgent problem to be solved. [0003] During ship construction, especially during the berth construction, due to construction needs, the manhole covers on the ship are not installed. During this time, the working water or rainwater on the ship flows into the interior of the hull through the manhole. However, the water inside the hull could not be discharged in time, causing serious water accumulation inside the hull, resulting in corrosion. These corroded places must be re-polished, sand washed, and painted, which brings a lot of repetitive work and cost waste to the...
