Problems solved by technology

[0004] 1. The manufacturing cycle is long, and the toxicity of the epoxy resin curing agent is harmful to the human body;
[0005] 2. The material of FRP is obviously brittle, and the collision will cause resin cracks, violent collision will cause crushing, and the safety hazard is prominent;
[0006] 3. Due to factors such as sun exposure and night dew, waves, surges, collisions and resin aging during use, frequent maintenance is required;
[0007] 4. It is difficult to do harmless treatment of FRP waste after scrapping, which will cause long-term harm to the environment

Abstract

The invention relates to the technical field of ship manufacturing, in particular to a ship which is integrally formed and a manufacturing method of the ship. A rotational moulding plastic ship comprises a ship body, and the ship body is a plastic ship which is made of plastic materials and is integrally formed through a rotational moulding technology. The plastic materials comprise polyolefin high polymer materials, PA nylon high polymer materials, HIPS high polymer materials, ABS high polymer materials, PMMA high polymer materials and PC high polymer materials. The ship body made of the plastic materials has the advantages of being good in strength, high in anti-impacting capacity, free of pollution, recyclable and the like.

Description

technical field [0001] The invention relates to the technical field of boat manufacturing, in particular to an integrally formed boat and a manufacturing method thereof. Background technique [0002] At present, known small boats generally refer to boats with a length of 2.5 meters to 15 meters, such as: non-powered boats, speedboats, yachts, etc., all of which are made of fiberglass. [0003] In the existing fiberglass material boat technology, the following defects often occur when boats are manufactured: [0004] 1. The manufacturing cycle is long, and the toxicity of the epoxy resin curing agent is harmful to the human body; [0005] 2. The material of FRP is obviously brittle, and the collision will cause resin cracks, violent collision will cause crushing, and the safety hazard is prominent; [0006] 3. Due to factors such as sun exposure and night dew, waves, surges, collisions and resin aging during use, frequent maintenance is required; [0007] 4. It is difficul...
