Problems solved by technology

[0002] At present, the sea lifeboats on the market include rubber boat lifeboats, fiberglass lifeboats and steel lifeboats, etc. The advantages of rubber boat lifeboats and fiberglass lifeboats are that the hulls are light in weight and easy to carry and transport. When the reef is broken, it will affect the rescue at sea and endanger the life safety of the rescuers; the advantage of the steel lifeboat is that it is resistant to impact, but the disadvantage is that the hull is very heavy, and it is not convenient to carry and quickly transport

Embodiment 1

[0045] 1. Manufacturing of the hull:

[0046] (1) Preparation of portable and impact-resistant marine lifeboat plates: Add polypropylene resin into the high-speed mixer, turn on the high-speed mixer, mix the materials at high speed for 15 minutes, release them and send them into the hopper of the plate extruder. Turn on the switch of the plate extruder, control the temperature of the first stage of the plate extruder to 210°C, the temperature of the second stage to 220°C, the temperature of the third stage to 230°C, the temperature of the fourth stage to 240°C, and control the screw speed to 400r / min. The width of the plate is 5000mm and the thickness is 4mm.

[0047] (2) Blister molding mold development: according to the shape of the portable, impact-resistant marine lifeboat shell, use wood to make a portable, impact-resistant marine lifeboat blister molding mold. After the wooden plastic forming mold is opened, the surface of the mold is treated with epoxy resin putty. The f...

[0071] 1. Manufacturing of the hull:

[0072] (1) Preparation of portable and impact-resistant marine lifeboat plates: Add nylon resin into the high-speed mixer, turn on the high-speed mixer, mix the materials at high speed for 20 minutes, release them and send them into the hopper of the plate extruder. Turn on the switch of the plate extruder, control the temperature of the first stage of the plate extruder to 220°C, the temperature of the second stage to 230°C, the temperature of the third stage to 250°C, the temperature of the fourth stage to 265°C, and control the screw speed to 500r / min. The width of the plate is 6000mm and the thickness is 10mm.

[0073] (2) Blister molding mold development: according to the shape of the portable, impact-resistant marine lifeboat shell, use aluminum alloy or wood to make a portable, impact-resistant marine lifeboat blister molding mold. If the wooden plastic forming mold is used, after the wooden plastic forming mold is opened, the sur...

Abstract

The invention relates to a production method for a portable and impact-resistant lifeboat at sea. A shell, a ballast water tank separator plate and a boat deck of the lifeboat are made of polypropylene sheet materials or nylon sheet materials; a front windshield cover, a back windshield cover and a middle push-and-pull windshield cover are all made of polyester sheet materials or polycarbonate sheet materials. A manufacturing method of the lifeboat shell comprises the steps of heating the polypropylene sheet materials or the nylon sheet materials by an oven; then sending the treated sheet materials to a plastic forming mold and making by a vacuum forming method. The front windshield cover, the back windshield cover and the middle push-and-pull windshield cover are all prepared by the plastic forming method. The ballast water tank separator plate and the shell of the lifeboat are welded together; the boat deck is laid on the ballast water tank separator plate; the boat is provided with waterproof and windshield transparent cover; the middle of the boat is provided with the movable push-and-pull windshield cover. The lifeboat has the advantages of small resistance, light weight, impact resistance, wind and wave resistance, corrosion resistance and ageing resistance, and is widely applied in rescues at sea, fishing in the sea, plays at sea, sports at sea, etc.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and relates to a manufacturing method of a portable and impact-resistant marine lifeboat. Background technique [0002] At present, the sea lifeboats on the market include rubber boat lifeboats, fiberglass lifeboats and steel lifeboats, etc. The advantages of rubber boat lifeboats and fiberglass lifeboats are that the hulls are light in weight and easy to carry and transport. The reef will be broken, which will affect the rescue at sea and endanger the life safety of the rescuers; the advantage of the steel lifeboat is that it is resistant to impact, but the disadvantage is that the hull is very heavy, and it is not convenient to carry and quickly carry it. Therefore, it is of great significance to develop a kind of light weight, easy to carry, impact-resistant sea lifeboat. Contents of the invention [0003] The object of the present invention is to provide a manufacturing method of a po...
