Abstract
The utility model relates to an anti-sink ship body, in particular to a ship body with filling material of foam in the empty cabin, which comprises a shell of ship and a board. The characteristics of the utility model are that utility model also comprises the foam layer between the shell of the ship and the board and the foam can be shaped in the empty cabin of the ship shell by the way of injection molding. The utility model has the functions of waterproof and sink preventing, which avoids the large lose of life and property.
Description
Technical field
The utility model relates to a kind of anti-shipwreck body, relates in particular to the empty cabin of a kind of hull and fills frothy hull.
Background technology
At present, the following of the hull clamping plate of passenger boat that we know and freighter is empty cabin, generally do not place article, main purpose is the weight that alleviates hull, dose its buoyancy, there is following shortcoming in this hull: when hull clashed into or breakage after, swelling is gone into the sinking that can cause ship in the ship very soon, brings massive losses for people's life, property safety.
Summary of the invention
The purpose of this utility model provides a kind of anti-shipwreck body, especially provides the empty cabin of a kind of hull to fill frothy hull.
The purpose of this utility model is finished by the following technical programs:
A kind of anti-shipwreck body comprises ship outer casing, deck, it is characterized in that: also comprise the froth bed of filling in the empty cabin between ship outer casing and the deck;
Described blister layer material is selected from any waterproof, plastic material, especially polymeric material, as: polyethylene, polypropylene, polyvinylchloride, polystyrene and ABS.
Described hull can be by the method for any melt molding, especially adopt the method for structural foam injection moulding to make: this method comprises preformed, prefoam, injection, demoulding, be that plastic molten mass is to foam in the injector barrel, it is the dissociation temperature that injector barrel heating-up temperature reaches foaming agent, make injector barrel screw axial slow astern set a distance behind the preformed again, make plastic molten mass that the space of foaming and intumescing be arranged, best backway is the space that makes plastic molten mass cubic expansion 1/5 to 1/4, and high-voltage high-speed injects molten mass on the mould of circulating water cooling subsequently;
Described plastic molten mass can be polyethylene, polypropylene, polyvinylchloride, polyphenyl second or alkene ABS.
Described structural foam is polypropylene preferably, makes foaming agent with Celogen Az, and described injector barrel heating-up temperature is: 150-210 ℃, 160-170 ℃ of spout temperature, preformed, pre-expansion time 10-20 second, injection speed 1-2 Kilograms Per Second, pressure 1000-1400 kg/cm
2, pressurize hardening time 100-120 second.
Described equipment and raw material all can be buied from market.
The utlity model has following advantage:
1, because in fact plastic foam has utilized ship outer casing to be mould, the foam molten mass is molded in the empty cabin of hull, with the hull formula structure that becomes one, simultaneously because the water-fast characteristics of plastic foam, when ship outer casing clashed into or damage and water inflow after, plastic foam has played waterproof effect for the second time.The plastic foam of these water resistancees can not soak in 72 hours, thereby had avoided the loss of people's life and property.
2, because specific foam weight is little, light weight does not influence hull weight, only occupies the space in sky cabin, has improved the value of hull greatly.
3, because the foam cost is low, cheap, saved manufacturing cost of the present utility model greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of anti-shipwreck body comprises ship outer casing 1, deck 2, it is characterized in that: also comprise the froth bed 3 of filling in the empty cabin between ship outer casing and the deck;
Described blister layer material, promptly plastic molten mass is selected from polypropylene.
Described hull adopts the method for structural foam injection moulding to make: this method has preformed, prefoam, injection, demoulding step, be that plastic molten mass is to foam in the injector barrel, it is the dissociation temperature that injector barrel heating-up temperature reaches foaming agent, make injector barrel screw axial slow astern set a distance behind the preformed again, make the space of plastic molten mass cubic expansion 1/4, high-voltage high-speed injects molten mass on the hull mould of circulating water cooling subsequently;
Make foaming agent with Celogen Az, described injector barrel heating-up temperature is 200 ℃, 170 ℃ of spout temperature, preformed, pre-expansion time 20 seconds, injection speed 1 Kilograms Per Second, pressure 1400 kg/cm
2, pressurize hardening time 120 seconds.
A kind of anti-shipwreck body comprises ship outer casing 1, deck 2, it is characterized in that: also comprise the froth bed 3 of filling in the empty cabin between ship outer casing and the deck;
Selecting polypropylene for use is foam raw material, presses embodiment 1 method manufacturing.Make foaming agent with Celogen Az, described injector barrel heating-up temperature is: 155 ℃, and 165 ℃ of spout temperature, preformed, pre-expansion time 15 seconds, injection speed 2 Kilograms Per Seconds, pressure 1200 kg/cm
2, pressurize hardening time 115 seconds.
Claims (4)
