Embodiment Construction

[0022] The present invention is further described below:

[0023] A method for manufacturing a fiberglass boat, the steps are as follows:

[0024] (1) For the production of the mold, the female mold is made of glass fiber reinforced plastic, and the inner surface is required to be smooth, and the finish is required to be a mirror surface.

[0025] (2) After the mold is qualified, wipe the surface of the mold with clean cotton gauze, then wax, dip a little wax liquid with cotton gauze, and apply it evenly on the surface of the mold in a spiral shape, and wait for it to dry for 15-25 minutes. Wipe the wax surface with a clean gauze, and then apply the remaining wax several times according to the above method, and finally polish it with a wool wheel.

[0026] (3) For gel coat spraying, first use adhesive tape to protect the periphery of the hull mold, use two spray guns to start at the same position, and finally meet at the same position to avoid excessive residence time during ...

Abstract

The invention relates to ships, in particular to a method for manufacturing glass reinforced plastic ships. The steps are as follows: mould manufacture, waxing, gel coat spraying, hull moulding, hull strengthening, first column laying, demoulding cloth paving and compressing, guide cloth paving and compressing, spiral tube laying, vacuum tube laying, vacuum film packaging and compressing, vacuum pumping, resin guiding, and the like. The method has the advantages of unique technology, smooth ship surface, short production cycle, low labor intensity, and the like, and environmental pollution can be reduced further.

Description

Technical field: [0001] The invention relates to a ship, in particular to a manufacturing method of a glass fiber reinforced plastic ship. Background technique: [0002] As we all know, the production of FRP ships generally adopts the mold method. The molds used include wooden molds, plaster molds, glass steel molds or cement molds, etc. Among them, wooden molds and glass steel molds are the most widely used. The surface is rough. For those fishing boats and transport ships that do not require too much appearance, wooden molds are often used. FRP molds can obtain high-quality outer surfaces, but the cost is high and the operation is cumbersome, especially prolonging the production cycle. For yachts, FRP molds are often used for passenger ships and speedboats with high appearance requirements. Invention content: [0003] The purpose of this utility model is to provide a kind of manufacturing method of the glass fiber reinforced plastic boat that adopts vacuum leading-in mo...
