Abstract

A kind of all-plastic boat, its hull is by being primary raw material with the PE plastics, other filler turning into modified plastic of add-on parts additive filling part processes through plastics rotational forming processing technology.Hull divides plastics outer surface layer, neutral fiber layer, plastic interior surfaces layer and local foaming layer.Carry out the accessory assembling again, made all-plastic boat.This gear has hygroscopic character little, and light, shock-resistant, withstanding corrosion, long service life, simple, the low cost and other advantages of manufacturing process become a kind of later-model marine communication means.

Description

All-plastic boat

The invention belongs to the shipbuilding technical field.

Existing inland river, lake, the transportation means of coastal beach, the means of delivery that the fisherman cultures usefulness generally all are wood structure, steel structure, cement structures, glass fibre reinforced plastic structure ship.All-plastic boat is compared advantage with existing various structure ships:

One, little, the without putrefaction of all-plastic boat hygroscopic character, and the wooden boat hygroscopic character is big, it is damaged to be easy to rot.

Two, in the same capability ratio, hull is light with steel structure ship, cement structures ship for all-plastic boat, and carrying capacity is big.

Three, all-plastic boat is with cement structures ship and glass fibre reinforced plastic structure ship ratio, because all-plastic boat constitutes hull for the compages layer, thereby it is strong to have hull toughness, the big advantage of anti-impulse force value.

Four, all-plastic boat has the strong advantage of salt tolerant, alkali, attack by acid that the steel structure ship is not had.

Five, all-plastic boat have that good integrity, cost that other structure ships do not have are low, processing is easy, raw material is sufficient, aesthetic in appearance, advantage such as be easy to promote the use of.

The purpose of the invention, provide the overall plastic structure ship that a kind of new material is made, it replaces nine meters of former length, load-carrying wood structure ship, steel structure ship, cement structures ship, the glass fibre reinforced plastic structure ship below 55 tons, makes it satisfy the advantage that existing ship does not have.

The content of the invention is: with the pE plastics is primary raw material, and add-on parts additive and filler become modified plastics, knocks down then in the container type ship pattern tool that is made of metal, and after 200 ℃ of-400 ℃ of fusions are heated in rotation, forms the hull surface layer.In like manner, with the pE plastics is primary raw material, and the add-on parts additive recharges staple glass fibre or the asbestos short fibre of 10%-50%, heat through rotation, formation is compounded in one deck fibrage on the superficial layer, is primary raw material with the pE plastics in like manner, and add-on parts additive and filler become modified plastics, heat through rotation, formation is compounded in one deck interior surface layers on the fibrage, thereby makes overall plastic hull, carries out demoulding 40 ℃ of following temperature then.And in the coverboard interlayer chamber at hull bottom and other relevant positions, carry out filled plastics and foam, like this through a whole set of plastics rotational forming processing technology, and plastic foamed processing technology just manufactures overall plastic hull, with parts and hull assembling match, becomes all-plastic boat again.

Advantages such as the invention has that hygroscopic character is small and light, tough, shock-resistant, withstanding corrosion, good integrity, long service life, manufacturing process are simple, low cost of manufacture.

Fig. 1 is ship section figure.

Fig. 2 is the hull part sectional view.

Fig. 3 is the rotary forming machine cutaway view.

Be example with canoe (5) among Fig. 1, plastics outer surface layer (6), neutral fiber layer (7), plastic interior surfaces layer (8), partial foaming layer (9) constitute hull.

With reference to Fig. 3.To knock down in the container mould (1) that is made of metal based on the raw material of pE plastics, and drive mould (1) through rotary forming machine (2) and go up at rocking carrier (3) and make rotation and banking motion up and down, the angle of inclination is between the 0-40 degree.Under the heating of double flame-thrower nozzle (4), its mould is included based on the raw material of pE plastics hang equably again at mould internal layer formation hull outer surface layer.In like manner, be compounded to form neutral fiber layer, the hull interior surface layers, these three layers are combined into one and become a synthetic layer, thereby have made overall plastic hull.Through demoulding under the cooling that being lower than 40 ℃, plastic foamed, accessory assembling again, made all-plastic boat.

Claims

1, a kind of all-plastic boat is characterized in that:

A plastics outer surface layer (6) is primary raw material, is added partly additive and filler and become modified plastics and form by the PE plastics, neutral fiber layer (7) is to be primary raw material by the PE plastics, add partly additive filling partly staple glass fibre or asbestos short fibre to form plastic interior surfaces layer (8) be to be primary raw material by the PE plastics, add part additive and filler and become the modified plastics composition, partial foaming layer (9) is that plastic foamed filling coverboard interlayer chamber forms;

B hull (5) is made of plastics outer surface layer (6), neutral fiber layer (7), plastic interior surfaces layer (8), partial foaming layer (9) Integratively.

2, all-plastic boat according to claim 1 is characterized in that the charging quantity of middle staple glass fibre of neutral fiber layer (7) or asbestos short fibre is preferably in 10%～50%.
