Problems solved by technology

[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

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 ...
