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 boat manufacturing, in particular to an integrally formed boat and a manufacturing method thereof. The rotomolded plastic boat includes a boat main body, and the boat main body is a plastic boat integrally formed by using plastic materials through a rotomolding process. Plastic materials include: polyolefin, PA nylon, HIPS, ABS, PMMA, PC polymer materials. The boat main body made by the invention has the advantages of good strength, strong impact resistance, no pollution, recyclability 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...
