Embodiment

[0047] A method for manufacturing a double-layer ship using foamed plastics, comprising the steps of:

[0048] 1. According to the quality requirements, the specifications of domestically produced expandable polystyrene F151 or F251 are matured into pre-expanded polystyrene particles at a density of 15-30 kg / m3; or made into particle foam according to the required density; Or make mature granular bubbles with plastic materials of other varieties.

[0049] 2. After the steel plate structure between the outer plate and the inner plate of the ship (1) is derusted by sandblasting, paint the adhesive, use asphalt 5# plus 30% gasoline or use 2127 phenolic glue, and put it on the outer plate and the inner plate. Brushing on steel plate structural plates such as mid-bottom longitudinal truss girder (16), main floor plate (17), reinforcing plate in the space.

[0050] 3, the pre-expanded polystyrene granule of slaking, all fills the slaking granule bubble in the hole of bow deck (15) ...

Abstract

The invention relates to a method to manufacture double-plate ships with foam plastic. The invention is characterized in that the method comprises the following steps: a twisted steel plate is used between an outside plate and an inside plate of the manufactured double-plate ship; the rust on the horizontal and vertical framework steel plates is removed by adopting the technology of sandblast and so on; adhesive is applied; aged pre-foamed polystyrene grains are filled, and are heated and expanded with high pressure heating steam so as to foam the grains. After the grains are cold, the foam is bonded with and is integrated with a steel structure between the outside plate and the inside plate. After the ship is smashed or strikes aground, the foam plastic inside the outside plate and the inside plate form buffering; the inside plate of the ship is not staved easily; and even if the outside plate is staved in, no water leaks. The invention has the advantages of high sailing safety coefficient of the ship, long service life and convenient corrective maintenance.

Description

Technical field: [0001] The invention relates to a method for manufacturing a double-slab ship by using foam plastics. The double-slab passenger ship, oil tanker, container ship, etc. manufactured are made of foam plastics and steel plates in the space between the outer steel plate and the inner steel plate of the double-slab ship. The structure is molded to make the ship strong and durable, and the safety factor of navigation is improved. Background technique: [0002] Double-bottom passenger ships, container ships, oil tankers, container ships, etc., which are welded by steel plates in shipbuilding technology, consume a lot of steel. After the outer and inner plates are corroded, the repair and maintenance costs are high. Navigation in dangerous waters is dangerous. When the ship is sailing, the outer steel plate is punctured by other ships, the steel plate is aged and rotten, or it hits a rock. If the outer steel plate of the ship is damaged, the ship will enter the wate...
